Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates and assumptions are subject to inherent uncertainties which may result in actual amounts differing from reported amounts. The Consolidated Financial Statements for the 13 weeks ended May 4, 2024 and April 29, 2023, in the opinion of management, include all adjustments (consisting only of normal recurring adjustments) considered necessary to present fairly, in all material respects, the consolidated financial position and results of operations of the Company.
Seasonality	Seasonality Because of the seasonal nature of the retail business, the results of operations for the 13 weeks ended May 4, 2024 and April 29, 2023 (which do not include the holiday season) are not necessarily indicative of such results for the full fiscal year.
Comprehensive Income	Comprehensive Income Total comprehensive income represents the change in equity during a period from sources other than transactions with shareholders and, as such, includes net income. For the Company, the only other components of total comprehensive income for the 13 weeks ended May 4, 2024 and April 29, 2023 relate to post employment and postretirement plan items. Settlement charges incurred are included as a separate component of income before income taxes in the Consolidated Statements of Income. Amortization reclassifications out of accumulated other comprehensive income (loss) are included in the computation of net periodic benefit cost (income) and are included in benefit plan income, net on the Consolidated Statements of Income.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendments in this update enhance segment reporting by expanding the breadth and frequency of segment disclosures required by public entities. Most notable, registrants will be required to disclose: (1) significant segment expenses regularly provided to the Chief Operating Decisions Maker ("CODM") and included within the reported measure(s) of a segment's profit or loss, (2) the amount and composition of other segment items, (3) how the CODM uses the reported measure(s) of a segment's profit or loss to assess segment performance and decide how to allocate resources, (4) on an interim basis, all segment profit or loss and asset disclosures currently required annually by Topic 280, as well as those introduced by the ASU, and (5) the CODM's title and position. ASU 2023-07 is effective for the Company beginning in the fiscal year ending February 1, 2025. The Company is currently evaluating the impacts of the adoption of ASU 2023-07. In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" (ASU 2023-09). The amendments in this update enhance the transparency and decision usefulness of income tax disclosures, primarily through improvements to the rate reconciliation and income taxes paid information, specifically requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation, and (2) income taxes paid disaggregation by jurisdiction. These amendments allow investors to better assess how an entity's operations and tax related risks and planning affects its income tax rate and prospects for future cash flows. ASU 2023-09 is effective for the Company beginning in the fiscal year ending January 31, 2026. The Company is currently evaluating the impacts of the adoption of ASU 2023-09.
Revenue	Retail Sales Retail sales include merchandise sales, inclusive of delivery income, licensed department income, Marketplace income, sales of private brand goods directly to third party retailers and sales of excess inventory to third parties. Sales of merchandise are recorded at point of sale for in-store purchases or the time of shipment to the customer for digital purchases and are reported net of estimated merchandise returns and certain customer incentives. Commissions earned on sales generated by licensed departments and Marketplace are included as a component of total net sales and are recognized as revenue at the time merchandise is sold to customers. Service revenues (e.g., alteration and cosmetic services) are recorded at the time the customer receives the benefit of the service. The Company has elected to present sales taxes on a net basis and sales taxes are included in accounts payable and accrued liabilities until remitted to the taxing authorities. Merchandise Returns The Company estimates merchandise returns using historical data and recognizes an allowance that reduces net sales and cost of sales. The liability for merchandise returns is included in accounts payable and accrued liabilities on the Company's Consolidated Balance Sheets and was $193 million, $136 million and $214 million as of May 4, 2024, February 3, 2024 and April 29, 2023, respectively. Included in prepaid expenses and other current assets is an asset totaling $116 million, $83 million and $127 million as of May 4, 2024, February 3, 2024 and April 29, 2023, respectively, for the recoverable cost of merchandise estimated to be returned by customers. Gift Cards and Customer Loyalty Programs The Company only offers no-fee, non-expiring gift cards to its customers. At the time gift cards are sold or issued, no revenue is recognized; rather, the Company records an accrued liability to customers. The liability is relieved, and revenue is recognized, equal to the amount redeemed at the time gift cards are redeemed for merchandise. The Company records revenue from unredeemed gift cards (breakage) in net sales on a pro-rata basis over the time period gift cards are actually redeemed. At least three years of historical data, updated annually, is used to determine actual redemption patterns. The Company maintains customer loyalty programs in which customers earn points based on their purchases. Under the Macy's Star Rewards loyalty program, points are earned based on customers' spending on Macy's private label and co-branded credit cards as well as non-proprietary cards and other forms of tender. Bloomingdale's Loyallist and Bluemercury BlueRewards programs provide tender neutral points-based programs to their customers. The Company recognizes the estimated net amount of the rewards that will be earned and redeemed as a reduction to net sales at the time of the initial transaction and as tender when the points are subsequently redeemed by a customer. The liability for unredeemed gift cards and customer loyalty programs is included in accounts payable and accrued liabilities on the Company's Consolidated Balance Sheets and was $349 million, $384 million and $360 million as of May 4, 2024, February 3, 2024 and April 29, 2023, respectively. Credit Card Revenues In 2005, in connection with the sale of most of the Company's credit card accounts and related receivable balances to Citibank, the Company and Citibank entered into a long-term marketing and servicing alliance pursuant to the terms of a Credit Card Program Agreement ("Credit Card Program"). Subsequent to this initial arrangement and associated amendments, on December 13, 2021, the Company entered into the sixth amendment to the amended and restated Credit Card Program with Citibank (the "Program Agreement"). The changes to the Credit Card Program's financial structure are not materially different from its previous terms. As part of the Program Agreement, the Company receives payments for providing a combination of interrelated services and intellectual property to Citibank in support of the underlying Credit Card Program. Revenue based on the spending activity of the underlying accounts is recognized as the respective card purchases occur and the Company's profit share is recognized based on the performance of the underlying portfolio. Revenue associated with the establishment of new credit accounts and assisting in the receipt of payments for existing accounts is recognized as such activities occur. Credit card revenues include finance charges, late fees and other revenue generated by the Company’s Credit Card Program, net of fraud losses and expenses associated with establishing new accounts, credit card funding costs and bad debt reserves and are a component of other revenue on the consolidated statements of income. The Program Agreement expires March 31, 2030, subject to an additional renewal term of three years. The Program Agreement provides for, among other things, (i) the ownership by Citibank of the accounts purchased by Citibank, (ii) the ownership by Citibank of new accounts opened by the Company’s customers, (iii) the provision of credit by Citibank to the holders of the credit cards associated with the foregoing accounts, (iv) the servicing of the foregoing accounts, and (v) the allocation between Citibank and the Company of the economic benefits and burdens associated with the foregoing and other aspects of the alliance. Pursuant to the Program Agreement, the Company continues to provide certain servicing functions related to the accounts and related receivables owned by Citibank and receives compensation from Citibank for these services. The amounts earned under the Program Agreement related to the servicing functions are deemed adequate compensation and, accordingly, no servicing asset or liability has been recorded on the Consolidated Balance Sheets.
