Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying interim financial statements of BJ’s Wholesale Club Holdings, Inc. are unaudited and, in the opinion of management, reflect all normal recurring adjustments considered necessary for a fair statement of the Company’s financial statements in accordance with generally accepted accounting principles in the United States of America ("GAAP"). The consolidated balance sheet as of February 2, 2019 is derived from the audited consolidated balance sheet as of that date. The unaudited results of operations for the first quarter of fiscal year 2019 are not necessarily indicative of future results or results to be expected for fiscal year 2019. The Company’s business, in common with the business of retailers generally, is subject to seasonal influences. The Company’s sales and operating income have typically been highest in the fourth quarter holiday season and lowest in the first quarter of each fiscal year. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K for fiscal year 2018, as filed with the Securities Exchange Commission (the "SEC") on March 25, 2019. Initial Public Offering On July 2, 2018, the Company completed the IPO, in which the Company issued and sold 43,125,000 shares of its common stock (including 5,625,000 shares of common stock that were subject to the underwriters’ option to purchase additional shares) at an initial public offering price of $17.00 per share. The Company received total aggregate proceeds of $685.9 million net of underwriters’ discounts, commissions and other transaction expenses, which totaled $47.2 million. On July 2, 2018, the Company used the net proceeds from the IPO to extinguish the total outstanding balance of $623.2 million of its senior secured second lien term loan facility (the “Second Lien Term Loan”). See Note 6, Debt and Credit Arrangements, for further discussion regarding the Second Lien Term Loan extinguishment. On October 1, 2018, certain selling stockholders completed the registered sale of 32,200,000 shares of the Company’s common stock at a public offering price of $26.00 per share. Of the 32,200,000 shares sold, 4,200,000 shares represented the underwriters’ exercise of their overallotment option. The Company did not receive any proceeds from this offering or incur underwriters’ discounts or commissions on the sale. The Company incurred transaction costs of $2.4 million primarily for legal, accounting and printer services related to the offering. On March 11, 2019, certain selling stockholders completed the registered sale (the "March 2019 Secondary Offering") of 19,550,000 shares of the Company's common stock at a public offering price of $25.08 per share. Of the 19,550,000 shares sold, 2,550,000 shares represented the underwriters’ exercise of their overallotment option. The Company did not receive any proceeds from the March 2019 Secondary Offering or incur underwriters’ discounts or commissions on the sale. The Company incurred transaction costs of $1.2 million primarily for legal, accounting and printer services related to the offering. Stock Split On June 15, 2018, the Company effected a seven-to-one stock split of its issued and outstanding shares of common stock and proportional adjustment to the existing conversion ratios for each series of the Company’s Contingently Redeemable Common Stock (see Note 9). Accordingly, all shares and per share amounts for all periods presented in the accompanying consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect this stock split and adjustment of the contingently redeemable common stock conversion ratios. Deferred Offering Costs The Company capitalized certain legal, professional, accounting and other third-party fees that were directly associated with the IPO as deferred offering costs. Upon the consummation of the IPO, $47.2 million was recorded in stockholders’ deficit as a reduction of additional paid-in capital. Recent Accounting Pronouncements The accounting policies the Company follows are set forth in the Company’s audited financial statements for fiscal year 2018. There have been no material changes to these accounting policies, except as noted below for new accounting pronouncements adopted at the beginning of fiscal year 2019. Leases (ASU 2016-2) In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-2, Leases (FASB Accounting Standards Codification (“ASC”) Topic 842, Leases) which requires recognition on the balance sheet for the rights and obligations created by leases with terms greater than twelve months. Consistent with prior GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee will depend primarily on its classification as a finance or operating lease. However, unlike prior GAAP—which required only finance (formerly capital) leases to be recognized on the balance sheet—the new ASU requires both types of leases to be recognized on the balance sheet. The ASU took effect for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. This standard can be applied at the beginning of the earliest period presented using the modified retrospective method, which includes certain practical expedients that an entity may elect to apply. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases and ASU 2018-11, Leases (Topic 842): Targeted Improvements, which make improvements to ASC 842 and allow entities to apply the new standards and not restate comparative periods in transition to ASC 842 and instead report the comparative periods under ASC 840. The Company adopted ASC 842 using the modified retrospective method at the beginning of the first quarter of fiscal year 2019. In accordance with ASC 842, the Company did not restate comparative periods in transition to ASC 842 and instead reported comparative periods under ASC 840. Adoption of the standard resulted in the initial recognition of $2.040 billion of operating lease right-of-use (“ROU”) assets and $2.071 billion of operating lease liabilities as of February 3, 2019. The difference between the assets and liabilities is attributable to the reclassification of certain existing lease-related assets and liabilities as an adjustment to the ROU assets. Finance leases were not impacted by the adoption of the new guidance as finance lease liabilities and the corresponding assets were recorded on the consolidated balance sheet under the previous guidance. The adoption of this standard did not have a material impact on the Company’s interim unaudited consolidated statements of operations and comprehensive income, statements of contingently redeemable common stock and stockholders’ deficit or cash flows, and had a $11.6 million impact on beginning retained earnings in fiscal year 2019 primarily associated with the impact of the Company's deferred gain on prior years' sale leaseback transactions, net of tax. The Company elected the transition package of practical expedients permitted within the new standard which, among other things, allowed it to carry-forward the historical lease classification. The Company did not elect the practical expedient to use hindsight in determining the lease term and in assessing impairment of ROU assets and therefore continued to utilize lease terms determined under previous lease guidance. Please refer to Note 4 – Leases for further discussion on the Company's leases. Non-Employee Share-Based Compensation (ASU 2018-07) In June 2018, the FASB issued ASU 2018-07 Improvements to Non-employee Share-Based Payment Accounting which updates the guidance to Compensation—Stock Compensation (Topic 718). The updated guidance aligns the measurement and classification guidance for share-based payments to non-employees with the guidance for share-based payments to employees, with certain exceptions. The Company adopted ASU 2018-07 at the beginning of the first quarter of fiscal year 2019 and the adoption of this standard did not have a material impact on its consolidated financial statements. Recently Issued Accounting Pronouncements Fair Value Measurement (ASU 2018-13) In August 2018, the FASB issued ASU 2018-13 Changes to the Disclosure Requirements for Fair Value Measurement which updates the guidance to Fair Value Measurement (Topic 820). The updated guidance modifies the disclosure requirements for fair value measurements by removing, modifying or adding certain disclosures. The updated guidance is effective for fiscal periods beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The Company does not anticipate the updated guidance will have a material impact on its consolidated financial statements. Intangibles-Goodwill and Other-Internal-Use Software (ASU 2018-15) In August 2018, the FASB issued ASU 2018-15 Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) The update related to accounting for implementation costs incurred in a cloud computing arrangement that is a service contract. The update allows entities who are customers in hosting arrangements that are service contracts to apply the existing internal-use software guidance to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The update specifies classification for capitalizing implementation costs and related amortization expense within the financial statements and requires additional disclosures. The updated guidance is effective for fiscal reporting periods, including interim reporting within those periods, beginning after December 15, 2019. Early adoption is permitted and can be applied either retrospectively or prospectively. The Company is currently evaluating the transition methods and the impact of the adoption of this standard on its consolidated financial statements. Goodwill Impairment (ASU 2017-04) In January 2017, the FASB issued ASU 2017-04. ASU 2017-04 provides amendments to ASC 350, "Intangibles - Goodwill and Other", which eliminate Step 2 from the goodwill impairment test. Entities should perform their goodwill impairment tests by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. The amendments in this update are effective prospectively during interim and annual periods beginning after December 15, 2019, with early adoption permitted. The Company does not believe adoption of this standard will have a material effect on the its consolidated financial statements. Credit Losses (ASU 2016-13) In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"). This new guidance will change how entities account for credit impairment for trade and other receivables, as well as for certain financial assets and other instruments. ASU 2016-13 will replace the current "incurred loss" model with an "expected loss" model. Under the "incurred loss" model, a loss (or allowance) is recognized only when an event has occurred (such as a payment delinquency) that causes the entity to believe that a loss is probable (i.e., that it has been "incurred"). Under the "expected loss" model, an entity will recognize a loss (or allowance) upon initial recognition of the asset that reflects all future events that will lead to a loss being realized, regardless of whether it is probable that the future event will occur. The "incurred loss" model considers past events and current conditions, while the "expected loss" model includes expectations for the future which have yet to occur. ASU 2016-13 is effective for public companies for fiscal years beginning after December 15, 2019 with early adoption permitted for fiscal years beginning after December 15, 2018, including interim periods therein. The standard will require entities to record a cumulative-effect adjustment to the balance sheet as of the beginning of the first reporting period in which the guidance is effective. The Company does not believe adoption of this standard will have a material impact on its consolidated financial statements.

Merchandise sales—The Company recognizes sale of merchandise at clubs and gas stations at the point of sale when the customer takes possession of the goods and tenders payment. At point of sale, the performance obligation is satisfied because control of the merchandise transfers to the customer. Sales of merchandise at the Company’s clubs and gas stations, excluding sales taxes, represent approximately 96% of the Company’s net sales and approximately 94% of the Company’s total revenues. Sales taxes are recorded as a liability at the point of sale. Revenue is recorded at the point of sale based on the transaction price on the merchandise tag, net of any applicable discounts, sales taxes and expected refunds. For e-commerce sales, the Company recognizes sales when control of the merchandise is transferred to the customer, which is typically at the shipping point.

BJ’s Perks Rewards and My BJ's Perks programs— The Company’s BJ’s Perks Rewards^® membership program allows participating members to earn 2% cash back, up to a maximum of $500 per year, on qualified purchases made at BJ’s. The Company also offers a co-branded credit card program, the My BJ’s Perks^® program, which allows My BJ's Perks^® Mastercard credit card holders to earn 3% or 5% cash back on eligible purchases made at BJ’s and 1% or 2% cash back on purchases made with the card outside of BJ’s. Cash back is in the form of electronic awards issued in $20 increments that may be used online or in-club at the register and expire six months from the date issued.

Earned awards may be redeemed on future purchases made at the Company. The Company recognizes revenue for earned awards when customers redeem such awards as part of a purchase at one of the Company’s clubs or the Company’s website. The Company accounts for these transactions as multiple element arrangements and allocates the transaction price to separate performance obligations using their relative fair values. The Company includes the fair value of award dollars earned in deferred revenue at the time the award dollars are earned. This liability was $27.6 million at May 4, 2019 and $23.5 million at May 5, 2018.

Royalty revenue received in connection with the My BJ's Perks co-brand credit card program is variable consideration and is considered deferred until the card holder makes a purchase. The Company’s total deferred royalty revenue related to the outstanding My BJ’s Perks Rewards was $13.3 million, $13.4 million and $12.7 million at May 4, 2019, February 2, 2019 and May 5, 2018, respectively. The timing of revenue recognition of these awards dollars is driven by actual customer activities, such as redemptions and expirations. The Company expects to recognize $10.4 million of the deferred revenue at May 4, 2019 in fiscal year 2019, and the remainder will be recognized in the years thereafter.

Membership—The Company charges a membership fee to its customers. That fee allows customers to shop in the Company’s clubs, shop on the Company’s website and purchase gas at the Company’s gas stations for the duration of the membership, which is generally 12 months. Because the Company has the obligation to provide access to its clubs, website and gas stations for the duration of the membership term, the Company recognizes membership fees on a straight-line basis over the life of the membership. The Company’s deferred revenue related to membership fees was $141.6 million, $134.4 million and $133.9 million at May 4, 2019, February 2, 2019 and May 5, 2018, respectively.

Gift Card Programs—The Company sells BJ’s gift cards that allow the customer to redeem the card for future purchases equal to the amount of the original purchase price of the gift card. Revenue from gift card sales is recognized upon redemption of the gift card because the Company’s performance obligation to redeem the gift card for merchandise is satisfied when the gift card is redeemed. Historically, the Company has recognized breakage under the remote model, which recognizes breakage income when the likelihood of the customer exercising its remaining rights becomes remote. Under the new guidance, the Company recognizes breakage in proportion to its rate of gift card redemptions. This change in breakage recognition model had an immaterial impact on the Company’s results of operations for each of the first quarters of fiscal year 2019 and fiscal year 2018, respectively. Deferred revenue related to gift cards was $8.0 million, $9.1 million and $8.1 million at May 4, 2019, February 2, 2019 and May 5, 2018, respectively. The Company recognized $11.1 million and $11.3 million of revenue from gift card redemptions in the first quarter of fiscal year 2019 and fiscal year 2018, respectively.

Disaggregation of Revenue

The Company’s club retail operations, which represent substantially all the consolidated total revenues, are the Company’s only reportable segment. All the Company’s identifiable assets are in the United States. The Company does not have significant sales outside the United States, nor does any customer represent more than 10% of total revenues for any period presented. The following table summarizes the Company’s percentage of net sales disaggregated by category for the first quarter of fiscal year 2019 and fiscal year 2018:



	Thirteen Weeks Ended
	May 4, 2019	May 5, 2018
Edible Grocery	24%	24%
Perishables	28%	29%
Non-Edible Grocery	22%	22%
General Merchandise	13%	12%
Gasoline and Other Ancillary Services	13%	13%

Leases [Abstract]

Leases

The Company adopted ASC 842 as of February 3, 2019, using the modified retrospective method and applying transitional relief allowing entities to initially apply the requirements at the adoption date by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, results and disclosures for the reporting periods beginning on February 3, 2019 are reported and presented under ASC 842, while prior period amounts and disclosures are not adjusted and continue to be reported and presented under ASC 840.

As part of the adoption, the Company elected the following practical expedients:

1. A package of practical expedients allowing the Company to: a) carry forward its historical lease classification; b) avoid reassessing whether any expired or existing contracts are or contain leases; and c) avoid reassessing initial direct costs for any existing leases.

2. A practical expedient related to land easements, allowing the Company to carry forward the accounting treatment for land easements on existing agreements and eliminating the need to reassess existing lease contracts to determine if land easements are separate leases under ASC 842.

The Company did not elect the following practical expedients:

1. A practical expedient that would allow the Company to use hindsight in determining the lease term and to assess impairment of the entity's ROU assets, since election of this expedient could make adoption more complex given that re-evaluation of the lease term.

2. A practical expedient allowing the Company to not separate lease components from nonlease components (e.g., common area maintenance costs) since currently the Company does not combine lease and nonlease components for any of its real estate leases.

In accordance with ASC 842 the Company determines if an arrangement is a lease at inception or modification of a contract, and classifies each lease as either operating or finance lease at commencement. The Company only reassesses lease classification subsequent to commencement upon a change to the expected lease term or the contract being modified. The Company has operating and finance leases for the Company's clubs, and operating leases for the Company's distribution centers, corporate office, and stand alone gas stations. Operating leases, net of accumulated amortization, are included in operating lease ROU assets, and current and noncurrent operating lease liabilities, on the interim unaudited consolidated balance sheet. Finance leases are included in property and equipment, accrued expenses and other current liabilities, and other noncurrent liabilities on the interim unaudited consolidated balance sheets. Lease liabilities are calculated using the effective interest method, regardless of classification, while the amortization of the ROU assets varies depending upon classification. Finance lease classification results in a front-loaded expense recognition pattern over the lease term, which amortizes the ROU asset by recognizing interest expense and amortization expense as separate components of lease expense and calculates the amortization expense component on a straight-line basis. Conversely, operating lease classification results in a straight-line expense recognition pattern over the lease term and recognizes lease expense as a single expense component, which results in amortization of the ROU asset that equals the difference between lease expense and interest expense. Lease expense for finance and operating leases are included in selling general and administrative expense on the interim unaudited consolidated statement of operations and comprehensive income. Leases with an initial term of twelve months or less are not recorded on the balance sheet.

The Company is generally obligated for the cost of property taxes, insurance, and maintenance relating to its leases, which are often variable lease payments. Such costs are presented as occupancy costs for finance and operating leases included in selling, general and administrative expense on the interim unaudited consolidated statement of operations and comprehensive income.

Certain of the Company's lease agreements provide for lease payments based on future sales volumes at the leased location, or include rental payments adjusted periodically for inflation or based on an index, which are not measurable at the inception of the lease. The Company expenses such variable amounts in the period incurred, which is the period in which it becomes probable that the specified target that triggers the variable lease payments will be achieved. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants.

ROU assets represent the right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the reasonably certain lease term. The operating lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option.

Where the Company's leases do not provide an implicit rate, the Company uses a collateralized incremental borrowing rate ("IBR") to determine the present value of lease payments. The collateralized IBR is based on a synthetic credit rating that is externally prepared on an annual basis at the measurement date, and that the Company adjusts quarterly with a yield curve that approximates the Company's market risk profile.

In calculating the present value of the lease payments, the Company has elected to utilize its estimated IBR based on the original lease term and not the remaining lease term. The initial primary term of the Company's operating leases ranges from 5 to 44 years, with most of these leases having an initial term of 20 years. The initial primary term of the Company's two finance leases are 20 years.

The adoption of ASC 842 resulted in the initial recognition of $2.040 billion of operating lease ROU assets and $2.071 billion of operating lease liabilities as of February 3, 2019. The difference between the assets and liabilities is attributable to the reclassification of certain existing lease-related assets and liabilities as an adjustment to the right-of-use assets. The Company derecognized assets and liabilities of $94.7 million and $125.8 million, respectively, in connection with the non-cash transitional adjustment. As a result of adopting ASC 842, the Company also recorded a charge to retained earnings of $11.6 million, primarily associated with the net of tax impact of the Company's deferred gain on prior years' sale leaseback transactions. Finance leases were not impacted by the adoption of the new guidance, as finance lease liabilities and the corresponding assets were recorded on the consolidated balance sheet under the previous guidance. The adoption of this standard did not materially impact the Company's consolidated statements of operations and comprehensive income, or the Company's consolidated statements of cash flows.

As of May 4, 2019, assets recorded under finance leases were $19.2 million and accumulated amortization associated with finance leases was $8.6 million, while ROU assets recorded as operating leases were $2.092 billion and accumulated amortization associated with operating leases was $35.8 million. In the first quarter of fiscal year 2019 the Company recorded a non-cash increase of $49.4 million to ROU assets and liabilities resulting from lease reassessments.
