| Basis of Presentation and Summary of Significant Accounting Policies | Basis of Presentation and Summary of Significant Accounting Policies Fiscal Year The Company’s fiscal year ends on January 31. For example, references to fiscal 2026 refer to the fiscal year ending January 31, 2026. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and applicable rules and regulations of the U.S. Securities and Exchange Commission (SEC) regarding interim financial reporting. Accordingly, they do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with GAAP. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended January 31, 2025, which was filed with the SEC on March 21, 2025.  In management’s opinion, these unaudited condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the Company’s financial position as of April 30, 2025 and the results of operations for the three months ended April 30, 2025 and 2024, and cash flows for the three months ended April 30, 2025 and 2024. The condensed balance sheet as of January 31, 2025 was derived from the audited consolidated financial statements but does not include all disclosures required by GAAP. The results of operations for the three months ended April 30, 2025 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period.  Principles of Consolidation The condensed consolidated financial statements include the accounts of Snowflake Inc., its wholly-owned subsidiaries, and a majority-owned subsidiary in which the Company has a controlling financial interest. All intercompany transactions and balances have been eliminated in consolidation. The Company records noncontrolling interest in its condensed consolidated financial statements to recognize the minority ownership interest in its majority-owned subsidiary. Profits and losses of the majority-owned subsidiary are attributed to controlling and noncontrolling interests using the hypothetical liquidation at book value method. Segment Information The Company has a single operating and reportable segment. The Company’s chief operating decision maker (CODM) is its Chief Executive Officer, who reviews financial information presented on a consolidated basis, including, but not limited to, the Company’s consolidated net loss, for purposes of making operating decisions, assessing financial performance, and allocating resources.  The following table presents selected financial information with respect to the Company’s single operating segment (in thousands):  
 (1)For the three months ended April 30, 2025 and 2024, respectively, approximately 68% and 65% of cost of product revenue represented third-party cloud infrastructure expenses incurred in connection with the customers’ use of the Snowflake platform and the deployment and maintenance of the platform on public clouds, including different regional deployments. (2)For the three months ended April 30, 2025 and 2024, respectively, approximately 34% and 37% of the Company’s total cost of revenue and operating expenses were comprised of personnel-related expenses, excluding stock-based compensation and associated payroll taxes. These expenses consist primarily of salaries, benefits, bonuses, sales commissions and draws paid to the Company’s sales force and certain referral fees paid to third parties, including amortization of deferred commissions, and associated payroll taxes. They also include salaries, benefits and bonuses allocated as part of overhead costs. See Note 11, “Equity,” for details regarding the Company’s stock-based compensation. The measure of segment assets is the total assets on the Company’s condensed consolidated balance sheets. See the Company’s condensed consolidated financial statements for other financial information regarding its operating segment.  For information regarding the Company’s revenue by geographic area, see Note 3, “Revenue, Accounts Receivable, Deferred Revenue, and Remaining Performance Obligations.” The following table presents the Company’s long-lived assets, comprising property and equipment, net and operating lease right-of-use assets, by geographic area (in thousands): 
 ________________ (1)No individual country outside of the United States accounted for more than 10% of the Company’s long-lived assets as of April 30, 2025 and January 31, 2025. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Such estimates include, but are not limited to, stand-alone selling prices (SSP) for each distinct performance obligation, internal-use software development costs, the expected period of benefit for deferred commissions, the fair value of intangible assets acquired in business combinations, the useful lives and impairment of long-lived assets, the carrying value of operating lease right-of-use assets, stock-based compensation, accounting for income taxes, and the fair value of investments in marketable and non-marketable securities. The Company bases its estimates on historical experience and also on assumptions that management considers reasonable. These estimates are assessed on a regular basis; however, actual results could differ from these estimates.  Summary of Significant Accounting Policies The Company’s significant accounting policies are discussed in “Note 2 – Basis of Presentation and Summary of Significant Accounting Policies” of the Company’s Annual Report on Form 10-K for the fiscal year ended January 31, 2025, which was filed with the SEC on March 21, 2025. There have been no significant changes to the Company’s accounting policies during the three months ended April 30, 2025, except for updates to the software development costs accounting policy, as described below.  Software Development Costs The Company capitalizes qualifying internal-use software development costs, which have historically related primarily to its cloud platform, under Accounting Standards Codification (ASC) Topic 350-40, Internal-use Software (ASC 350-40). The costs consist of personnel costs (including related benefits and stock-based compensation) that are incurred during the application development stage. Capitalization of costs begins when two criteria are met: (1) the preliminary project stage is completed, and (2) it is probable that the software will be completed and used for its intended function. Capitalization ceases when the software is substantially complete and ready for its intended use, including the completion of all significant testing. Costs related to preliminary project activities and post-implementation operating activities are expensed as incurred. Capitalized internal-use software development costs are included in property and equipment, net on the condensed consolidated balance sheets. These costs are amortized over the estimated useful life of the software, which is three years, on a straight-line basis. Cost and accumulated amortization of fully amortized capitalized internal-use software development costs are removed from the Company’s condensed consolidated balance sheets when the related software is no longer in use. The amortization of capitalized internal-use software development costs related to the Company’s platform applications is primarily included in cost of revenue in the condensed consolidated statements of operations. During the three months ended April 30, 2025, the Company began marketing the Snowflake platform to selected public sector customers who will have contractual rights to take possession of the Company’s software and who will contract with third parties to host the Company’s software. As a result, the Company’s ongoing and future software development costs related to the Snowflake platform must be accounted for under ASC 985-20, Costs of Software to be Sold, Leased or Marketed (ASC 985-20). All costs to establish technological feasibility are expensed as they are incurred. Technological feasibility is established when the working model is complete, which typically occurs at or shortly before the general release of the software products. Costs incurred subsequent to establishing technological feasibility are capitalized until the software product is available for general release to customers, at which point they are amortized on a product-by-product basis. Software development costs capitalized under ASC 985-20 are included in property and equipment, net on the condensed consolidated balance sheets, and are tested for impairment whenever events or changes in circumstances occur that could impact their recoverability. Software development costs that meet the criteria for capitalization were not material for the three months ended April 30, 2025. Software development costs capitalized prior to fiscal 2026 in connection with the Snowflake platform will be amortized over their remaining useful life and recognized as cost of revenue.

| Revenue, Accounts Receivable, Deferred Revenue, and Remaining Performance Obligations | Revenue, Accounts Receivable, Deferred Revenue, and Remaining Performance Obligations Disaggregation of Revenue Revenue consists of the following (in thousands):  
 Revenue by geographic area, based on the location of the Company’s customers (or end-customers under reseller arrangements), was as follows (in thousands):  
 ________________ (1)No individual country in these areas represented more than 10% of the Company’s revenue for all periods presented.  (2)Includes Europe, the Middle East and Africa. Accounts Receivable, Net As of April 30, 2025 and January 31, 2025, allowance for credit losses of $4.2 million and $4.8 million, respectively, was included in the Company’s accounts receivable, net balance. Significant Customers For purposes of assessing the concentration of credit risk and significant customers, a group of customers under common control or customers that are affiliates of each other are regarded as a single customer. As of April 30, 2025 and January 31, 2025, there were no customers that represented 10% or more of the Company’s accounts receivable, net balance. Additionally, there were no customers that represented 10% or more of the Company’s revenue for each of the three months ended April 30, 2025 and 2024. Deferred Revenue The Company recognized $820.9 million and $673.5 million of revenue for the three months ended April 30, 2025 and 2024, respectively, from the deferred revenue balances as of January 31, 2025 and 2024, respectively. Remaining Performance Obligations Remaining performance obligations (RPO) represent the amount of contracted future revenue that has not yet been recognized, including (i) deferred revenue and (ii) non-cancelable contracted amounts that will be invoiced and recognized as revenue in future periods. The Company’s RPO excludes performance obligations from on-demand arrangements as there are no minimum purchase commitments associated with these arrangements, and certain time and materials contracts that are billed in arrears. Portions of RPO that are not yet invoiced and are denominated in foreign currencies are revalued into U.S. dollars each period based on the applicable period-end exchange rates.  As of April 30, 2025, the Company’s RPO was $6.7 billion, of which the Company expects approximately 50% to be recognized as revenue in the twelve months ending April 30, 2026 based on historical customer consumption patterns. However, the amount and timing of revenue recognition are generally dependent upon customers’ future consumption, which is inherently variable at customers’ discretion and can extend beyond the original contract term in cases where customers are permitted to roll over unused capacity to future periods, generally on the purchase of additional capacity at renewal. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Cash Equivalents, Investments and Strategic Investments | Cash Equivalents, Investments and Strategic Investments Cash Equivalents and Investments The following is a summary of the Company’s cash equivalents, short-term investments, and long-term investments on the condensed consolidated balance sheets (in thousands): 
 
 The Company included $22.4 million and $23.6 million of interest receivable in prepaid expenses and other current assets on the condensed consolidated balance sheets as of April 30, 2025 and January 31, 2025, respectively. The Company did not recognize an allowance for credit losses against interest receivable as of April 30, 2025 and January 31, 2025 because such potential losses were not material. As of April 30, 2025, the contractual maturities of the Company’s available-for-sale marketable debt securities did not exceed 36 months. The estimated fair values of available-for-sale marketable debt securities, classified as short-term or long-term investments on the Company’s condensed consolidated balance sheets, by remaining contractual maturity, are as follows (in thousands): 
 Gross unrealized losses on the Company’s available-for-sale marketable debt securities were not material as of April 30, 2025 and January 31, 2025. For available-for-sale marketable debt securities with unrealized loss positions, the Company does not intend to sell these securities and it is more likely than not that the Company will hold these securities until maturity or a recovery of the cost basis. The decline in fair values of these securities due to credit related factors was not material as of April 30, 2025 and January 31, 2025. Strategic Investments The Company’s strategic investments consist primarily of non-marketable equity securities recorded at cost minus impairment, if any, and adjusted for observable transactions for the same or similar investments of the same issuer (referred to as the Measurement Alternative).

| Fair Value Measurements | Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value as follows: Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. The following table presents the fair value hierarchy for the Company’s assets and liabilities measured at fair value on a recurring basis as of April 30, 2025 (in thousands): 
 The following table presents the fair value hierarchy for the Company’s assets and liabilities measured at fair value on a recurring basis as of January 31, 2025 (in thousands): 
 The Company determines the fair value of its security holdings based on pricing from the Company’s service providers and market prices from industry-standard independent data providers. Such market prices may be quoted prices in active markets for identical assets (Level 1 inputs) or pricing determined using inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs), such as yield curve, volatility factors, credit spreads, default rates, loss severity, current market and contractual prices for the underlying instruments or debt, broker and dealer quotes, as well as other relevant economic measures. The Company’s derivative financial instruments, consisting of foreign currency forward contracts, are carried at fair value on the condensed consolidated balance sheets. The following table summarizes the notional amounts of the Company’s outstanding derivative financial instruments (in thousands): 
 These derivative financial instruments did not have a material impact on the Company’s condensed consolidated financial statements for all periods presented. The Company’s non-marketable equity securities accounted for using the Measurement Alternative are recorded at fair value on a non-recurring basis. When indicators of impairment exist or observable price changes of qualified transactions occur, the respective non-marketable equity security would be classified within Level 3 of the fair value hierarchy because significant unobservable inputs or data in an inactive market are used in estimating their fair value. The estimation of fair value for these assets requires the use of an observable transaction price or other unobservable inputs, including the volatility, rights, and obligations of the securities the Company holds. See Note 4, “Cash Equivalents, Investments and Strategic Investments,” for details regarding the Company’s strategic investments. See Note 9, “Convertible Senior Notes,” for the fair value measurement of the Company’s convertible senior notes. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Convertible Senior Notes | Convertible Senior Notes In September 2024, the Company issued an aggregate principal amount of $2.3 billion of convertible senior notes in a private placement to qualified institutional buyers, comprising of (i) $1.15 billion aggregate principal amount of 0% convertible senior notes due 2027 (2027 Notes) and (ii) $1.15 billion aggregate principal amount of 0% convertible senior notes due 2029 (2029 Notes, and together with the 2027 Notes, the Notes). Each series of Notes was issued pursuant to separate indentures, as supplemented (each an Indenture and together, the Indentures), between the Company and U.S. Bank Trust Company, National Association, as trustee. The Notes are general, senior unsecured obligations of the Company. The 2027 Notes will mature on October 1, 2027 and the 2029 Notes will mature on October 1, 2029, in each case unless earlier converted, redeemed, or repurchased. Neither the 2027 Notes nor the 2029 Notes bear regular interest, and the principal amount of the Notes will not accrete. The Company may elect or be required to pay special interest on the Notes under certain circumstances in accordance with the terms of the applicable Indenture. Special interest, if any, will be payable semiannually in arrears on April 1 and October 1 of each year, beginning on April 1, 2025. The total proceeds from the issuance of the Notes were approximately $2.27 billion, net of $31.2 million of debt issuance costs.  The following table presents the details of each series of Notes: 
 The conversion rate for each series of Notes is subject to adjustment under certain circumstances in accordance with the terms of the applicable Indenture. In addition, following certain corporate events that occur prior to the maturity date of the relevant series of Notes or if the Company delivers a notice of redemption in respect of a series of Notes, the Company will, in certain circumstances, increase the conversion rate of the relevant series of Notes for a holder who elects to convert its Notes of the applicable series in connection with such a corporate event or convert its Notes called (or deemed called) for redemption during the related redemption period (as defined in the applicable Indenture), as the case may be. Holders may convert all or any portion of the 2027 Notes and 2029 Notes at their option at any time prior to the close of business on the business day immediately preceding July 1, 2027 and July 1, 2029, respectively, in each case only upon satisfaction of one or more of the following conditions:  (1) during any fiscal quarter commencing after the fiscal quarter ending on January 31, 2025 (and only during such fiscal quarter), if the last reported sale price of the Company’s Class A common stock, par value $0.0001 per share, for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price for the relevant series of Notes on each applicable trading day;  (2) during the five business day period after any ten consecutive trading day period (Measurement Period) in which the trading price (as defined in the Indentures) per $1,000 principal amount of the 2027 Notes or the 2029 Notes, as applicable, for each trading day of the Measurement Period was less than 98% of the product of the last reported sale price of the Company’s Class A common stock and the conversion rate for such Notes on each such trading day;  (3) if the Company calls the relevant series of Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, but only with respect to the Notes called (or deemed called) for redemption; or  (4) upon the occurrence of specified corporate events as set forth in the applicable Indenture.  On or after July 1, 2027, in the case of the 2027 Notes, and on or after July 1, 2029, in the case of the 2029 Notes, until the close of business on the second scheduled trading day immediately preceding the relevant maturity date, holders of the relevant series of Notes may convert all or any portion of their Notes of such series at any time, regardless of the foregoing conditions.  Upon conversion, the Company may satisfy its conversion obligation by paying or delivering, as the case may be, cash, shares of the Company’s Class A common stock or a combination of both, at the Company’s election, in the manner and subject to the terms and conditions provided in the applicable Indenture. The Company may, at its option, redeem for cash all or any portion of the 2027 Notes (subject to the partial redemption limitation set forth in the Indenture governing the 2027 Notes), on or after April 6, 2026 if the last reported sale price of the Company’s Class A common stock has been at least 150% of the conversion price then in effect for the 2027 Notes for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the 2027 Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date. The Company may, at its option, redeem for cash all or any portion of the 2029 Notes (subject to the partial redemption limitation set forth in the Indenture governing the 2029 Notes), on or after October 6, 2027 if the last reported sale price of the Company’s Class A common stock has been at least 130% of the conversion price then in effect for the 2029 Notes for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the 2029 Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date. No sinking fund is provided for the Notes. If the Company undergoes a fundamental change (as defined in the applicable Indenture) prior to the maturity date of a series of Notes, then, subject to certain conditions and except as set forth in the applicable Indenture, holders of the relevant series of Notes may require the Company to repurchase for cash all or any portion of their Notes of such series at a fundamental change repurchase price equal to 100% of the principal amount of the relevant series of Notes to be repurchased, plus accrued and unpaid special interest, if any, to, but excluding, the relevant fundamental change repurchase date. Each of the Indentures governing the 2027 Notes or the 2029 Notes includes customary covenants and sets forth certain events of default after which the relevant series of Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default (as defined in the applicable Indenture) involving the Company after which such Notes become automatically due and payable.  Each series of Notes is accounted for as a liability in its entirety, measured at amortized cost. The debt issuance costs for each series of the Notes are amortized to interest expense using the effective interest method over their respective terms, with effective interest rates of 0.04% for the 2027 Notes and 0.02% for the 2029 Notes. The following table presents the net carrying values and fair values of each series of Notes as of April 30, 2025 (in thousands): 
 The fair value was determined based on the quoted prices of the Notes in an inactive market on the last traded day of the fiscal quarter and has been classified as Level 2 in the fair value hierarchy. Amortization of debt issuance costs was not material for the three months ended April 30, 2025. The Company used a portion of the net proceeds from the offering to (i) pay the $195.5 million cost of the privately negotiated capped call transactions relating to each series of the Notes, as described below, and (ii) repurchase $399.6 million of its Class A common stock from purchasers of the Notes in the offering in privately negotiated transactions entered into in connection with the Notes offering at a purchase price of $112.50 per share. Capped Call Transactions In connection with the Notes offering, the Company entered into privately negotiated capped call transactions relating to each series of Notes (Capped Calls) with certain of the initial purchasers or affiliates thereof and certain other financial institutions. The Capped Calls are generally expected to reduce the potential dilution to the Company’s Class A common stock upon any conversion of the relevant series of the Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted Notes of such series, as the case may be, with such reduction and/or offset subject to a cap based on a cap price initially equal to $225.00 per share.  The following table sets forth other key terms and premiums paid for the Capped Calls related to each series of Notes (in thousands, except per share data): 
 The Capped Calls are separate transactions, and not part of the terms of any series of Notes. As the Capped Calls qualify for a scope exception from derivative accounting for instruments that are both indexed to the issuer’s own stock and classified in stockholders’ equity, the premiums paid for the purchases of the Capped Calls was recorded as a reduction to the additional paid-in capital and will not be remeasured as long as they continue to meet the conditions for equity classification. The Company elected to integrate the Capped Calls with the Notes for income tax purposes pursuant to applicable U.S. Treasury Regulations. Accordingly, the premiums paid for the purchases of the Capped Calls are deductible for income tax purposes over the term of the Notes. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Commitments and Contingencies | 3 Months Ended |

| Apr. 30, 2025 | |
| Commitments and Contingencies Disclosure [Abstract] | |
| Commitments and Contingencies | Commitments and Contingencies Operating Leases—The Company leases its facilities for office space under non-cancelable operating leases with various expiration dates through fiscal 2039. Certain lease agreements include options to renew or terminate the lease, which are not reasonably certain to be exercised and therefore are not factored into the determination of lease payments. During the three months ended April 30, 2025, the Company recognized impairment charges of $85.9 million for operating lease right-of-use assets and $20.6 million for property and equipment, net, primarily relating to the cease-use of its San Mateo office facility. These impairment charges represent the amounts by which the carrying values of the asset groups exceeded their estimated fair values, and were recorded as general and administrative expenses on the condensed consolidated statement of operations. The fair values of the impaired asset groups were estimated using discounted cash flow models (income approach) based on market participant assumptions, including the expected downtime prior to the commencement of future subleases, projected sublease income over the remaining lease periods, and discount rates to reflect the level of risk associated with receiving future cash flows. These assumptions are classified within Level 3 inputs of the fair value hierarchy. The fair values of the impaired asset groups are not material. As of April 30, 2025, the Company had committed $48.2 million, net of tenant incentives expected to be received, for leases signed but not yet commenced based on the exchange rate as of April 30, 2025. These leases will commence on various dates starting in fiscal 2026 with lease terms ranging from 5.3 years to 12.8 years. In addition, the Company subleases certain of its unoccupied facilities to third parties with various expiration dates through fiscal 2030. Such subleases have all been classified as operating leases. Sublease income is recorded as a reduction to the Company’s operating lease costs. Sublease income was $1.4 million and $2.4 million for the three months ended April 30, 2025 and 2024, respectively. Other Contractual Commitments—Other contractual commitments relate mainly to third-party cloud infrastructure agreements and subscription arrangements used to facilitate the Company’s operations at the enterprise level. There were no material contractual obligations that were entered into during the three months ended April 30, 2025 that were outside the ordinary course of business. 401(k) Plan—The Company sponsors a 401(k) defined contribution plan covering all eligible U.S. employees. Contributions to the 401(k) plan are discretionary. The Company did not make any matching contributions to the 401(k) plan for each of the three months ended April 30, 2025 and 2024. Legal Matters—On March 23, 2021, a former employee filed a charge with the National Labor Relations Board (NLRB) claiming that he was terminated in retaliation for engaging in concerted activity protected under the National Labor Relations Act. On September 15, 2023, following a hearing before a NLRB administrative law judge, the administrative law judge issued his ruling in favor of the former employee and ordered that he be awarded certain compensatory and other damages. The Company is appealing the ruling to the Board of the NLRB. The Company believes it is reasonably possible that a loss could ultimately result from an unfavorable outcome and that an estimate of the potential range of loss is between zero and $25 million, plus interest. No material loss accrual was recorded on the Company’s condensed consolidated balance sheets as of April 30, 2025 and January 31, 2025, because management believes the likelihood of material loss resulting from this charge is not probable given the further appellate proceedings that are due to take place. On February 29, 2024, a stockholder class action lawsuit was filed against the Company, the Company’s former Chief Executive Officer, and the Company’s Chief Financial Officer in the United States District Court in the Northern District of California, alleging violations under Sections 10(b) and 20(a) of the Exchange Act. The complaint seeks an unspecified amount of damages, attorneys’ fees, expert fees, and other costs. On October 28, 2024, an amended complaint was filed by the lead plaintiff. On December 23, 2024, the Company filed a motion to dismiss the amended complaint. On January 29, 2025, the lead plaintiff informed the Company that it would seek leave to file a second amended complaint rather than respond to the motion to dismiss. On April 7, 2025, the lead plaintiff filed its second amended complaint. The Company plans to file a motion to dismiss the second amended complaint on or before June 6, 2025. In addition, since the filing of the class action lawsuit, four additional complaints containing securities derivative claims have been filed against the Company and certain of the Company’s directors and executive officers alleging similar violations. The derivative claims have been stayed pending resolution of the anticipated motion to dismiss the class action lawsuit. The Company is unable to estimate any reasonably possible loss, or range of loss, with respect to these matters at this time. The Company and the other defendants intend to vigorously defend against the claims in these actions. On June 13, 2024, a class action was filed in the United States District Court for the District of Montana against the Company alleging that the Company failed to take reasonable measures to secure systems that contained consumer data, thereby allowing threat actors to access and exfiltrate personally identifiable information. In the months that followed, numerous additional class actions making the same or similar allegations were filed in the United States and Canada against the Company and/or customers whose consumer or employee data was exfiltrated. Among other claims, the complaints assert common law claims for negligence, breach of fiduciary duty, breach of implied contract, and unjust enrichment, as well as statutory claims, and seek an unspecified amount of damages, attorneys’ fees and costs, as well as injunctive relief. On October 4, 2024, an order was issued by the United States Judicial Panel on Multidistrict Litigation combining the class actions filed in the United States into a multidistrict litigation in the District of Montana. On February 3, 2025, plaintiffs filed their representative complaint on behalf of the consumer plaintiffs. On February 14, 2025, the Court created a separate financial institution track to represent the interests of certain financial institutions (FI Plaintiffs) and ordered that a separate FI Plaintiff representative complaint be filed. On March 21, 2025, the plaintiffs filed an amended representative complaint on behalf of the consumer plaintiffs. On April 7, 2025, an FI Plaintiff representative complaint was filed. On April 14, 2025, the plaintiffs filed a second amended representative complaint on behalf of the consumer plaintiffs. On May 16, 2025, the Company filed a motion to dismiss the second amended representative complaint on behalf of the consumer plaintiffs. On May 20, 2025, the plaintiffs filed a third amended representative complaint that asserted additional claims against the Company on behalf of individuals impacted by the breach of a Snowflake customer account containing personally identifiable information from the Los Angeles Unified School District. The Company’s deadline to respond to the FI Plaintiff representative complaint is June 26, 2025. In addition to the multidistrict litigation, a class action is pending in the Supreme Court of British Columbia. The Company is unable to estimate any reasonably possible loss, or range of loss, with respect to these matters at this time. The Company intends to vigorously defend against the claims in these actions. In addition, the Company is involved from time to time in various claims and legal actions arising in the ordinary course of business. While it is not feasible to predict or determine the ultimate outcome of these matters, the Company believes that none of its current legal proceedings will have a material adverse effect on its financial position, results of operations, or cash flows. Letters of Credit—As of April 30, 2025, the Company had a total of $20.8 million in cash collateralized letters of credit outstanding, substantially in favor of certain landlords for the Company’s leased facilities. These letters of credit renew annually and expire at various dates through fiscal 2033. Indemnification—The Company enters into indemnification provisions under agreements with other parties in the ordinary course of business, including business partners, investors, contractors, customers, and the Company’s officers, non-employee directors, and certain employees. The Company has agreed to indemnify and defend the indemnified party for claims and related losses suffered or incurred by the indemnified party from actual or threatened third-party claims due to the Company’s activities or non-compliance with certain representations and warranties made by the Company. It is not possible to determine the maximum potential loss under these indemnification provisions due to the Company’s limited history of prior indemnification claims and the unique facts and circumstances involved in each particular provision. For each of the three months ended April 30, 2025 and 2024, losses recorded in the condensed consolidated statements of operations in connection with the indemnification provisions, where the Company is an indemnifying party, were not material. |

| Equity | Equity Common Stock—The Company had reserved shares of common stock for future issuance as follows (in thousands): 
 Stock Repurchase Program and Treasury Stock—In February 2023, the Company’s board of directors authorized a stock repurchase program of up to $2.0 billion of the Company’s outstanding Class A common stock. Repurchases may be effected, from time to time, either on the open market (including via pre-set trading plans), in privately negotiated transactions, or through other transactions in accordance with applicable securities laws. The timing and amount of any repurchases will be determined by management based on an evaluation of market conditions and other factors. The program does not obligate the Company to acquire any particular amount of common stock, and the repurchase program may be suspended or discontinued at any time at the Company’s discretion. In August 2024, the Company’s board of directors authorized the repurchase of an additional $2.5 billion of its outstanding common stock and extended the expiration date of the stock repurchase program from March 2025 to March 2027. The following table summarizes the stock repurchase activity under the Company’s stock repurchase program (in thousands, except per share data): 
 ________________ (1)Excludes transaction costs and excise tax associated with the repurchases. All repurchases presented in the table above were made in open market transactions. As of April 30, 2025, $1.5 billion remained available for future stock repurchases under the stock repurchase program (exclusive of any transaction costs associated with repurchases). The first 0.5 million shares repurchased under the Company’s authorized stock repurchased program were recorded in treasury stock as a reduction to the stockholders’ equity on the condensed consolidated balance sheets. All shares of Class A common stock subsequently repurchased were retired. Upon retirement, the par value of the common stock repurchased was deducted from common stock and any excess of repurchase price (including associated transaction costs) over par value was recorded entirely to retained earnings (accumulated deficit) on the condensed consolidated balance sheets. Equity Incentive Plans—The Company’s 2020 Equity Incentive Plan (2020 Plan), which became effective in connection with its Initial Public Offering (IPO), provides for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards (RSUs), performance awards and other forms of equity compensation (collectively, equity awards). All shares that remain available for future grants are under the 2020 Plan.  The Company’s 2012 Equity Incentive Plan (2012 Plan) provided for the grant of equity awards to employees, non-employee directors, and other service providers of the Company. The 2012 Plan was terminated in September 2020 in connection with the IPO but continues to govern the terms of outstanding awards that were granted prior to the termination of the 2012 Plan. Upon the expiration, forfeiture, cancellation, or reacquisition of any shares of common stock underlying outstanding equity awards granted under the 2012 Plan, an equal number of shares of Class A common stock will become available for grant under the 2020 Plan. No further equity awards will be granted under the 2012 Plan. The Company’s 2020 Employee Stock Purchase Plan (2020 ESPP) authorizes the issuance of shares of common stock pursuant to purchase rights granted to employees. Offering periods are generally six months long and begin on the first trading day on or after March 15 and September 15 of each year, except for the first two offering periods. The initial offering period began on September 15, 2020 and ended on February 26, 2021. The second offering period began on March 1, 2021 and ended on September 14, 2021.  On February 1, 2025, the shares available for grant under the 2020 Plan and the 2020 ESPP were automatically increased by 16.7 million shares and 3.3 million shares, respectively, pursuant to the annual evergreen increase provisions under the 2020 Plan and the 2020 ESPP. Stock Options—Stock options granted under the 2012 Plan and the 2020 Plan (collectively, the Plans) generally vest based on continued service over four years and expire ten years from the date of grant. Certain stock options granted under the 2012 Plan are exercisable at any time following the date of grant and expire ten years from the date of grant. A summary of stock option activity during the three months ended April 30, 2025 is as follows: 
 No options were granted during the three months ended April 30, 2025. During the three months ended April 30, 2024, the Company granted a stock option with a grant-date fair value of $77.89 per share. The intrinsic value of options exercised in the three months ended April 30, 2025 and 2024 was $129.5 million and $241.8 million, respectively. The aggregate grant-date fair value of options that vested during the three months ended April 30, 2025 and 2024 was $7.7 million and $7.3 million, respectively. Equity-Classified RSUs—RSUs granted under the 2012 Plan are equity-classified and had both service-based and performance-based vesting conditions, of which the performance-based vesting condition was satisfied upon the effectiveness of the IPO in September 2020. The service-based vesting condition for these awards is typically satisfied over four years with a cliff vesting period of one year and continued vesting quarterly thereafter. Stock-based compensation associated with RSUs granted under the 2012 Plan was recognized using an accelerated attribution method from the time it was deemed probable that the vesting condition was met through the time the service-based vesting condition had been achieved.  Equity-classified RSUs granted under the 2020 Plan include those that only contain a service-based vesting condition that is typically satisfied over four years, and the related stock-based compensation for these RSUs is recognized on a straight-line basis over the requisite service period. In addition, under the 2020 Plan, the Company granted 0.4 million and 0.8 million equity-classified RSUs (Leadership PRSUs) to its executive officers and certain other members of its senior leadership team during the three months ended April 30, 2025 and 2024, respectively. These Leadership PRSUs were granted at 120% of the target number of these awards, representing the maximum number of Leadership PRSUs that may be eligible to vest over their full term, and have both service-based and performance-based vesting conditions. The service-based vesting condition for these Leadership PRSUs is typically satisfied over four years with a cliff vesting period of one year and continued vesting quarterly thereafter. The performance-based vesting condition is satisfied upon the achievement of certain Company annual performance targets set by the compensation committee of the board of directors of the Company. The ultimate number of the Leadership PRSUs eligible to vest ranges between 0% to 120% of the target number of the Leadership PRSUs based on the weighted-average achievement of such Company annual performance metrics for the respective fiscal year. Stock-based compensation associated with these Leadership PRSUs is recognized using an accelerated attribution method over the requisite service period, based on the Company’s periodic assessment of the probability that the performance condition will be achieved. Stock-based compensation recognized for these Leadership PRSUs was $13.8 million and $12.5 million for the three months ended April 30, 2025 and 2024, respectively. A summary of equity-classified RSUs activity during the three months ended April 30, 2025 is as follows: 
 ________________ (1)Represents an adjustment in the number of shares outstanding, with regards to Leadership PRSUs granted during the three months ended April 30, 2024, based on the actual achievement of the associated Company annual performance targets for fiscal 2025. Liability-Classified RSUs—During the fourth quarter of fiscal 2024, in connection with a business combination, the Company agreed to grant, under the 2020 Plan, RSUs that contain both post-combination service-based and performance-based vesting conditions (Acquisition PRSUs) to eligible existing or future employees, subject to a maximum total number of approximately 1.7 million shares. The post-combination service-based vesting condition for these Acquisition PRSUs is satisfied over four years with a cliff vesting period of one year and continued vesting quarterly thereafter. The performance-based vesting condition is contingent on the achievement of certain performance metric over the twelve-month period ending January 31, 2027. Acquisition PRSUs will vest when both service-based and performance-based conditions are satisfied. The ultimate number of Acquisition PRSUs eligible to vest is determined based on the actual achievement of the performance metric, which takes into account certain factors including the Company’s stock price and market capitalization. Once granted, Acquisition PRSUs are initially liability-classified and recorded in other liabilities on the Company’s condensed consolidated balance sheets, as the monetary value of the obligation under each potential outcome of the performance condition is predominantly based on a fixed monetary amount known at inception and will be settled in a variable number of shares. Subsequently, these awards are remeasured to the fair value at each reporting date until the number of Acquisition PRSUs eligible to vest is fixed, at which time these awards will be reclassified to equity. Stock-based compensation associated with these awards is recognized based on the probable outcome of the performance condition, using an accelerated attribution method over the requisite service period, with a cumulative catch-up adjustment recognized for changes in the fair value estimated at each reporting date. As of April 30, 2025, the liabilities associated with these Acquisition PRSUs were not material. As of January 31, 2025, the liabilities associated with these Acquisition PRSUs were $11.1 million.  A summary of liability-classified RSUs activity during the three months ended April 30, 2025 is as follows: 
 Restricted Common Stock—From time to time, the Company has granted restricted common stock outside of the Plans. Restricted common stock is not deemed to be outstanding for accounting purposes until it vests.  A summary of restricted common stock activity during the three months ended April 30, 2025 is as follows: 
 Stock-Based Compensation—The following table summarizes the assumptions used in estimating the fair values of a stock option granted to an employee during the three months ended April 30, 2024: 
 In addition, for the stock option granted during the three months ended April 30, 2024, the shares to be issued upon exercise are subject to a one-year holding period. As such, the Company applied a 7.6% discount for lack of marketability to the fair value estimated using the Black-Scholes option-pricing model, based on the assumptions included in the table above. No stock options were granted during the three months ended April 30, 2025. The following table summarizes the assumptions used in estimating the fair values of employee stock purchase rights granted under the 2020 ESPP (ESPP Rights) during each of the three months ended April 30, 2025 and 2024: 
 Expected term—For stock options considered to be “plain vanilla” options, the Company estimates the expected term based on the simplified method, which is essentially the weighted average of the vesting period and contractual term, as the Company’s historical option exercise experience does not provide a reasonable basis upon which to estimate the expected term. The expected term for ESPP Rights approximates the offering period. Expected volatility—The Company uses the average of (i) the historical volatility of its Class A common stock, and (ii) the implied volatility from publicly traded options on its Class A common stock to develop an expected volatility assumption. Risk-free interest rate—Risk-free rate is estimated based upon quoted market yields for the United States Treasury debt securities for a term consistent with the expected life of the awards in effect at the time of grant. Expected dividend yield—Because the Company has never paid and has no intention to pay cash dividends on common stock, the expected dividend yield is zero. Fair value of underlying common stock—The fair value of the Company’s common stock is determined by the closing price, on the date of grant, of its common stock, which is traded on the New York Stock Exchange. The following table summarizes the assumptions used in estimating the fair value of liability-classified Acquisition PRSUs as of April 30, 2025 and January 31, 2025: 
 Expected volatility—The Company uses the average of (i) the historical volatility of its Class A common stock, and (ii) the implied volatility from publicly traded options on its Class A common stock to develop an expected volatility assumption. Risk-free interest rate—Risk-free rate is estimated based upon quoted market yields for the United States Treasury debt securities for a term that approximates the period from the reporting date to January 31, 2027. Stock-based compensation included in the condensed consolidated statements of operations was as follows (in thousands): 
 As of April 30, 2025, total compensation cost related to unvested awards not yet recognized was $3.7 billion, which will be recognized over a weighted-average period of 2.9 years. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Income Tax Disclosure [Abstract] | |
| Income Taxes | Income Taxes The Company computes its tax provision for interim periods by applying the estimated annual effective tax rate to year-to-date pre-tax income from recurring operations and adjusting for discrete tax items arising in that quarter. The Company had an effective tax rate of (1.4%) and (0.9%) for the three months ended April 30, 2025 and 2024, respectively. The Company has incurred U.S. operating losses and has minimal profits in foreign jurisdictions. The Company has evaluated all available evidence, both positive and negative, including historical levels of income and expectations and risks associated with estimates of future taxable income, and has determined that it is more likely than not that its net deferred tax assets will not be realized in the United States and the United Kingdom. Due to uncertainties surrounding the realization of the deferred tax assets, the Company maintains a full valuation allowance against its net deferred tax assets. The Company is subject to income taxes in the United States and numerous foreign jurisdictions. As of April 30, 2025, tax years 2012 and forward generally remain open for examination for U.S. federal and state tax purposes, and tax years 2020 and forward generally remain open for examination for foreign tax purposes. The Company has applied ASC 740 and determined that it has uncertain tax positions giving rise to unrecognized tax benefits for each of the three months ended April 30, 2025 and 2024. The Company’s policy is to recognize interest and penalties related to uncertain tax positions in income tax expense. The Company does not anticipate any significant changes to its unrecognized tax benefits over the next 12 months, and no material amount related to these unrecognized tax benefits, if recognized, would have an impact on the Company’s effective tax rate. On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 (Inflation Act) into law. The Inflation Act contains certain tax measures, including a corporate alternative minimum tax of 15% on some large corporations and an excise tax of 1% on stock repurchases. For each of the three months ended April 30, 2025 and 2024, the Inflation Act had no material impact to the Company’s aggregate tax liability, financial position and results of operations, including its stock repurchase program. |

| Net Loss per Share | Net Loss per Share Basic and diluted net loss per share attributable to Snowflake Inc. Class A common stockholders is computed in conformity with the two-class method required for participating securities. The Company considers unvested common stock to be participating securities, as the holders of such stock have the right to receive nonforfeitable dividends on a pari passu basis in the event that a dividend is declared on common stock. Basic net loss per share attributable to Snowflake Inc. Class A common stockholders is computed by dividing net loss attributable to Snowflake Inc. Class A common stockholders by the weighted-average number of shares of Snowflake Inc. Class A common stock outstanding during the period, which excludes treasury stock. Diluted net loss per share attributable to Snowflake Inc. Class A common stockholders is computed by giving effect to all potentially dilutive Snowflake Inc. Class A common stock equivalents to the extent they are dilutive. For purposes of this calculation, stock options, RSUs, restricted common stock, ESPP Rights, and shares underlying the conversion option in the Notes are considered to be common stock equivalents but have been excluded from the calculation of diluted net loss per share attributable to Snowflake Inc. Class A common stockholders as their effect is anti-dilutive for all periods presented. The following table presents the calculation of basic and diluted net loss per share attributable to Snowflake Inc. Class A common stockholders (in thousands, except per share data): 
 No Class B common stock was outstanding during any periods presented. The following potentially dilutive securities were excluded from the calculation of diluted net loss per share attributable to Snowflake Inc. Class A common stockholders for the periods presented because the impact of including them would have been anti-dilutive (in thousands): 
 The Company entered into the Capped Calls in connection with the Notes offering. The effect of the Capped Calls was also excluded from the calculation of diluted net loss per share attributable to Snowflake Inc. Class A common stockholders as the effect of the Capped Calls would have been anti-dilutive. The Capped Calls are generally expected to reduce the potential dilution to the Company’s Class A common stock upon any conversion of the relevant series of the Notes. See Note 9, “Convertible Senior Notes,” for further details. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Basis of Presentation and Summary of Significant Accounting Policies (Policies) | 3 Months Ended | 
|---|---|
| Apr. 30, 2025 | |
| Accounting Policies [Abstract] | |
| Fiscal Year | Fiscal Year The Company’s fiscal year ends on January 31. For example, references to fiscal 2026 refer to the fiscal year ending January 31, 2026. | 
| Basis of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and applicable rules and regulations of the U.S. Securities and Exchange Commission (SEC) regarding interim financial reporting. Accordingly, they do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with GAAP. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended January 31, 2025, which was filed with the SEC on March 21, 2025. In management’s opinion, these unaudited condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the Company’s financial position as of April 30, 2025 and the results of operations for the three months ended April 30, 2025 and 2024, and cash flows for the three months ended April 30, 2025 and 2024. The condensed balance sheet as of January 31, 2025 was derived from the audited consolidated financial statements but does not include all disclosures required by GAAP. The results of operations for the three months ended April 30, 2025 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period. | 
| Principles of Consolidation | Principles of Consolidation The condensed consolidated financial statements include the accounts of Snowflake Inc., its wholly-owned subsidiaries, and a majority-owned subsidiary in which the Company has a controlling financial interest. All intercompany transactions and balances have been eliminated in consolidation. The Company records noncontrolling interest in its condensed consolidated financial statements to recognize the minority ownership interest in its majority-owned subsidiary. Profits and losses of the majority-owned subsidiary are attributed to controlling and noncontrolling interests using the hypothetical liquidation at book value method. | 
| Segment Information | Segment InformationThe Company has a single operating and reportable segment. The Company’s chief operating decision maker (CODM) is its Chief Executive Officer, who reviews financial information presented on a consolidated basis, including, but not limited to, the Company’s consolidated net loss, for purposes of making operating decisions, assessing financial performance, and allocating resources.The measure of segment assets is the total assets on the Company’s condensed consolidated balance sheets. | 
| Use of Estimates | Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Such estimates include, but are not limited to, stand-alone selling prices (SSP) for each distinct performance obligation, internal-use software development costs, the expected period of benefit for deferred commissions, the fair value of intangible assets acquired in business combinations, the useful lives and impairment of long-lived assets, the carrying value of operating lease right-of-use assets, stock-based compensation, accounting for income taxes, and the fair value of investments in marketable and non-marketable securities.The Company bases its estimates on historical experience and also on assumptions that management considers reasonable. These estimates are assessed on a regular basis; however, actual results could differ from these estimates. | 
| Software Development Costs | Software Development Costs The Company capitalizes qualifying internal-use software development costs, which have historically related primarily to its cloud platform, under Accounting Standards Codification (ASC) Topic 350-40, Internal-use Software (ASC 350-40). The costs consist of personnel costs (including related benefits and stock-based compensation) that are incurred during the application development stage. Capitalization of costs begins when two criteria are met: (1) the preliminary project stage is completed, and (2) it is probable that the software will be completed and used for its intended function. Capitalization ceases when the software is substantially complete and ready for its intended use, including the completion of all significant testing. Costs related to preliminary project activities and post-implementation operating activities are expensed as incurred. Capitalized internal-use software development costs are included in property and equipment, net on the condensed consolidated balance sheets. These costs are amortized over the estimated useful life of the software, which is three years, on a straight-line basis. Cost and accumulated amortization of fully amortized capitalized internal-use software development costs are removed from the Company’s condensed consolidated balance sheets when the related software is no longer in use. The amortization of capitalized internal-use software development costs related to the Company’s platform applications is primarily included in cost of revenue in the condensed consolidated statements of operations. Software development costs capitalized prior to fiscal 2026 in connection with the Snowflake platform will be amortized over their remaining useful life and recognized as cost of revenue. | 
| Revenue Recognition and Remaining Performance Obligations | Remaining Performance ObligationsRemaining performance obligations (RPO) represent the amount of contracted future revenue that has not yet been recognized, including (i) deferred revenue and (ii) non-cancelable contracted amounts that will be invoiced and recognized as revenue in future periods. The Company’s RPO excludes performance obligations from on-demand arrangements as there are no minimum purchase commitments associated with these arrangements, and certain time and materials contracts that are billed in arrears. Portions of RPO that are not yet invoiced and are denominated in foreign currencies are revalued into U.S. dollars each period based on the applicable period-end exchange rates. | 
| Capped Call Transactions | The Capped Calls are separate transactions, and not part of the terms of any series of Notes. As the Capped Calls qualify for a scope exception from derivative accounting for instruments that are both indexed to the issuer’s own stock and classified in stockholders’ equity, the premiums paid for the purchases of the Capped Calls was recorded as a reduction to the additional paid-in capital and will not be remeasured as long as they continue to meet the conditions for equity classification. | 
| Recently Issued Accounting Pronouncements Not Yet Adopted | Recently Issued Accounting Pronouncements Not Yet Adopted In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires annual disclosure on disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. This guidance is effective for the Company for its fiscal year beginning February 1, 2025 on a prospective basis. Early adoption and retrospective application are permitted. The Company is currently evaluating the impact of the adoption of this guidance on its disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40), which requires disclosure, on an annual and interim basis, of specified information about certain costs and expenses in the notes to financial statements. This guidance is effective for the Company for its fiscal year beginning February 1, 2027 and interim periods within its fiscal year beginning February 1, 2028 on either a prospective or retrospective basis. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of this guidance on its disclosures. | 
| Strategic Investments | The Company’s strategic investments consist primarily of non-marketable equity securities recorded at cost minus impairment, if any, and adjusted for observable transactions for the same or similar investments of the same issuer (referred to as the Measurement Alternative). | 
| Fair Value of Financial Instruments | Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value as follows: Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. The Company determines the fair value of its security holdings based on pricing from the Company’s service providers and market prices from industry-standard independent data providers. Such market prices may be quoted prices in active markets for identical assets (Level 1 inputs) or pricing determined using inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs), such as yield curve, volatility factors, credit spreads, default rates, loss severity, current market and contractual prices for the underlying instruments or debt, broker and dealer quotes, as well as other relevant economic measures.The Company’s derivative financial instruments, consisting of foreign currency forward contracts, are carried at fair value on the condensed consolidated balance sheets.The Company’s non-marketable equity securities accounted for using the Measurement Alternative are recorded at fair value on a non-recurring basis. When indicators of impairment exist or observable price changes of qualified transactions occur, the respective non-marketable equity security would be classified within Level 3 of the fair value hierarchy because significant unobservable inputs or data in an inactive market are used in estimating their fair value. The estimation of fair value for these assets requires the use of an observable transaction price or other unobservable inputs, including the volatility, rights, and obligations of the securities the Company holds. The fair value was determined based on the quoted prices of the Notes in an inactive market on the last traded day of the fiscal quarter and has been classified as Level 2 in the fair value hierarchy. | 
| Treasury Stock, Policy | All shares of Class A common stock subsequently repurchased were retired. Upon retirement, the par value of the common stock repurchased was deducted from common stock and any excess of repurchase price (including associated transaction costs) over par value was recorded entirely to retained earnings (accumulated deficit) on the condensed consolidated balance sheets. | 
| Net Loss Per Share | Basic and diluted net loss per share attributable to Snowflake Inc. Class A common stockholders is computed in conformity with the two-class method required for participating securities. The Company considers unvested common stock to be participating securities, as the holders of such stock have the right to receive nonforfeitable dividends on a pari passu basis in the event that a dividend is declared on common stock. Basic net loss per share attributable to Snowflake Inc. Class A common stockholders is computed by dividing net loss attributable to Snowflake Inc. Class A common stockholders by the weighted-average number of shares of Snowflake Inc. Class A common stock outstanding during the period, which excludes treasury stock. Diluted net loss per share attributable to Snowflake Inc. Class A common stockholders is computed by giving effect to all potentially dilutive Snowflake Inc. Class A common stock equivalents to the extent they are dilutive. For purposes of this calculation, stock options, RSUs, restricted common stock, ESPP Rights, and shares underlying the conversion option in the Notes are considered to be common stock equivalents but have been excluded from the calculation of diluted net loss per share attributable to Snowflake Inc. Class A common stockholders as their effect is anti-dilutive for all periods presented. The Company entered into the Capped Calls in connection with the Notes offering. The effect of the Capped Calls was also excluded from the calculation of diluted net loss per share attributable to Snowflake Inc. Class A common stockholders as the effect of the Capped Calls would have been anti-dilutive. The Capped Calls are generally expected to reduce the potential dilution to the Company’s Class A common stock upon any conversion of the relevant series of the Notes. See Note 9, “Convertible Senior Notes,” for further details. | 
| Impairment or Disposal of Long-Lived Assets, Policy | These impairment charges represent the amounts by which the carrying values of the asset groups exceeded their estimated fair values, and were recorded as general and administrative expenses on the condensed consolidated statement of operations. The fair values of the impaired asset groups were estimated using discounted cash flow models (income approach) based on market participant assumptions, including the expected downtime prior to the commencement of future subleases, projected sublease income over the remaining lease periods, and discount rates to reflect the level of risk associated with receiving future cash flows. These assumptions are classified within Level 3 inputs of the fair value hierarchy. The fair values of the impaired asset groups are not material. | 
| Research, Development, and Computer Software, Policy | During the three months ended April 30, 2025, the Company began marketing the Snowflake platform to selected public sector customers who will have contractual rights to take possession of the Company’s software and who will contract with third parties to host the Company’s software. As a result, the Company’s ongoing and future software development costs related to the Snowflake platform must be accounted for under ASC 985-20, Costs of Software to be Sold, Leased or Marketed (ASC 985-20). All costs to establish technological feasibility are expensed as they are incurred. Technological feasibility is established when the working model is complete, which typically occurs at or shortly before the general release of the software products. Costs incurred subsequent to establishing technological feasibility are capitalized until the software product is available for general release to customers, at which point they are amortized on a product-by-product basis. Software development costs capitalized under ASC 985-20 are included in property and equipment, net on the condensed consolidated balance sheets, and are tested for impairment whenever events or changes in circumstances occur that could impact their recoverability. Software development costs that meet the criteria for capitalization were not material for the three months ended April 30, 2025. |

| Fair Value Disclosures [Abstract] | |
| Fair Value of Financial Instruments | Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value as follows: Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. The Company determines the fair value of its security holdings based on pricing from the Company’s service providers and market prices from industry-standard independent data providers. Such market prices may be quoted prices in active markets for identical assets (Level 1 inputs) or pricing determined using inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs), such as yield curve, volatility factors, credit spreads, default rates, loss severity, current market and contractual prices for the underlying instruments or debt, broker and dealer quotes, as well as other relevant economic measures.The Company’s derivative financial instruments, consisting of foreign currency forward contracts, are carried at fair value on the condensed consolidated balance sheets.The Company’s non-marketable equity securities accounted for using the Measurement Alternative are recorded at fair value on a non-recurring basis. When indicators of impairment exist or observable price changes of qualified transactions occur, the respective non-marketable equity security would be classified within Level 3 of the fair value hierarchy because significant unobservable inputs or data in an inactive market are used in estimating their fair value. The estimation of fair value for these assets requires the use of an observable transaction price or other unobservable inputs, including the volatility, rights, and obligations of the securities the Company holds. The fair value was determined based on the quoted prices of the Notes in an inactive market on the last traded day of the fiscal quarter and has been classified as Level 2 in the fair value hierarchy. |
