Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	Revenue The Company’s revenues include merchandise sales at stores, online, and through franchise agreements. We also receive revenue sharing from our credit card agreement for private label and co-branded credit cards, and breakage revenue related to our gift cards, credit vouchers, and outstanding loyalty points. Breakage revenue is recognized based upon historical redemption patterns. For online sales and catalog sales, the Company has elected to treat shipping and handling as fulfillment activities and not as a separate performance obligation. Accordingly, we recognize revenue for our single performance obligation related to online sales and catalog sales at the time control of the merchandise passes to the customer, which is generally at the time of shipment. We also record an allowance for estimated merchandise returns based on our historical return patterns and various other assumptions that management believes to be reasonable. Revenues are presented net of any taxes collected from customers and remitted to governmental authorities. Our credit card agreement provides for certain payments to be made to us, including a share of revenue from the performance of the credit card portfolios and reimbursements of loyalty program discounts. We have identified separate performance obligations related to our credit card agreement that include both providing a license and an obligation to redeem loyalty points issued under the loyalty rewards program. Our obligation to provide a license is satisfied when the subsequent sale or usage occurs and our obligation to redeem loyalty points is deferred until those loyalty points are redeemed. Income related to our credit card agreement is classified within net sales on our Consolidated Statements of Income. We also have franchise agreements with unaffiliated franchisees to operate Gap, Banana Republic, and Old Navy stores in a number of countries throughout Asia, Europe, Latin America, the Middle East, and Africa. Under these agreements, third parties operate, or will operate, stores that sell apparel and related products under our brand names. We have identified separate performance obligations related to our franchise agreements that include both providing our franchise partners with a license and an obligation to supply franchise partners with our merchandise. Our obligation to provide a license is satisfied when the subsequent sale or usage occurs and our obligation to supply franchise partners with our merchandise is satisfied when control of the merchandise transfers. As of February 1, 2020 and February 2, 2019, there were no material contract liabilities related to our franchise agreements. We defer revenue when cash payments are received in advance of performance for unsatisfied obligations related to our gift cards, credit vouchers, outstanding loyalty points, and reimbursements of loyalty program discounts associated with our credit card agreement. For fiscal 2019, the opening balance of deferred revenue for these obligations was $227 million, of which $188 million was recognized as revenue during the period. The closing balance of deferred revenue related to gift cards, credit vouchers, outstanding loyalty points, and reimbursements of loyalty program discounts was $226 million as of February 1, 2020. For fiscal 2018, the opening balance of deferred revenue for these obligations was $232 million, of which $200 million was recognized as revenue during the period. The closing balance of deferred revenue related to gift cards, credit vouchers, outstanding loyalty points, and reimbursements of loyalty program discounts was $227 million as of February 2, 2019. We expect that the majority of our revenue deferrals as of February 1, 2020 will be recognized as revenue in the next 12 months as our performance obligations are satisfied.
