Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Description and Accounting Policies [Text Block]	Background Business. CarMax, Inc. (“we,” “our,” “us,” “CarMax” and “the company”), including its wholly owned subsidiaries, is the nation’s largest retailer of used vehicles. We operate in two reportable segments: CarMax Sales Operations and CarMax Auto Finance (“CAF”). Our CarMax Sales Operations segment consists of all aspects of our auto merchandising and service operations, excluding financing provided by CAF. Our CAF segment consists solely of our own finance operation that provides financing to customers buying retail vehicles from CarMax. The company operates in two operating segments, CarMax Sales Operations and CAF, both of which are reportable segments. The chief executive officer, who serves as the company’s chief operating decision maker (“CODM”), reviews the performance of our CarMax Sales Operations segment at the gross profit level, the components of which are presented within the consolidated statements of earnings. The CODM uses gross profit to assess financial performance, monitor forecasted versus actual results and adjust pricing strategy. The required segment information related to our CAF segment is presented in Note 3. Additionally, asset information by segment is not utilized for purposes of assessing performance or allocating resources and, as a result, such information has not been presented. We deliver an unrivaled customer experience by offering a broad selection of quality used vehicles and related products and services at competitive, no-haggle prices using a customer-friendly sales process. Our omni-channel experience provides a common platform across all of CarMax that leverages our scale, nationwide footprint and infrastructure and empowers our customers to buy a vehicle on their terms, whether online, in-store or through a seamless combination of both. Our associates, stores, technology and digital capabilities seamlessly tied together enable us to provide the most customer-centric car buying and selling experience, a key differentiator in a very large and fragmented market. We offer customers a range of related products and services, including the appraisal and purchase of vehicles directly from consumers and dealers; the financing of retail vehicle purchases through CAF and third-party finance providers; the sale of extended protection plan (“EPP”) products, which include extended service plans (“ESPs”) and guaranteed asset protection (“GAP”); advertising and subscription services; and vehicle repair service. Vehicles purchased through the appraisal process that do not meet our retail standards are sold to licensed dealers through on-site or virtual wholesale auctions. Basis of Presentation and Use of Estimates. The accompanying interim unaudited consolidated financial statements include the accounts of CarMax and our wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. These interim unaudited consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, such interim consolidated financial statements reflect all normal recurring adjustments considered necessary to present fairly the financial position and the results of operations and cash flows for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full fiscal year. The accounting policies followed in the presentation of our interim financial results are consistent with those included in the company’s Annual Report on Form 10-K for the fiscal year ended February 28, 2025 (the “2025 Annual Report”), with the exception of those related to recent accounting pronouncements adopted in the current fiscal year. These interim unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and footnotes included in our 2025 Annual Report. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Certain prior year amounts have been reclassified to conform to the current year’s presentation. Amounts and percentages may not total due to rounding. Recent Accounting Pronouncements. Effective in Future Periods In July 2025, the Financial Accounting Standards Board (“FASB”) issued an accounting pronouncement (ASU 2025-05) related to credit losses for accounts receivable and contract assets. The amendments in this update provide a practical expedient permitting an entity to assume that conditions at the balance sheet date remain unchanged over the life of the asset when estimating expected credit losses for current accounts receivable and current contract assets. This update is effective for annual periods beginning after December 15, 2025, including interim periods within those fiscal years, though early adoption is permitted. We plan to adopt this pronouncement for our fiscal year beginning March 1, 2026, and we do not expect it to have a material effect on our consolidated financial statements. In September 2025, the FASB issued an accounting pronouncement (ASU 2025-06) related to accounting for internal-use software costs. The amendments in this update improve the operability of the guidance by removing all references to software development project stages so that the guidance is neutral to different software development methods. This update is effective for annual periods beginning after December 15, 2027, including interim periods within those fiscal years, though early adoption is permitted. We plan to adopt this pronouncement for our fiscal year beginning March 1, 2028. We are currently in the process of evaluating the effects of this pronouncement on our consolidated financial statements.
