Accounting Policies [Abstract]
Basis of Presentation	The accompanying consolidated balance sheet as of December 31, 2023, which is derived from audited consolidated financial statements, and the unaudited consolidated financial statements, including the notes thereto, includes the accounts of FirstCash Holdings, Inc. and its wholly-owned subsidiaries (together, the “Company”). The Company regularly makes acquisitions, and the results of operations for the acquisitions have been consolidated since the acquisition dates. All significant intercompany accounts and transactions have been eliminated. These unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the rules and regulations for reporting on Form 10-Q. Accordingly, they do not include certain information and disclosures required for comprehensive financial statements. These interim period financial statements should be read in conjunction with the Company’s audited consolidated financial statements, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on February 5, 2024. The consolidated financial statements as of March 31, 2024 and 2023, and for the three month periods ended March 31, 2024 and 2023, are unaudited, but in management’s opinion include all adjustments (consisting of only normal recurring adjustments) considered necessary to present fairly the financial position, results of operations and cash flow for such interim periods. Operating results for the period ended March 31, 2024 are not necessarily indicative of the results that may be expected for the full year. The Company has pawn operations in Latin America, where in Mexico, Guatemala and Colombia, the functional currency is the Mexican peso, Guatemalan quetzal and Colombian peso. Accordingly, the assets and liabilities of these subsidiaries are translated into U.S. dollars at the exchange rate in effect at each balance sheet date, and the resulting adjustments are accumulated in other comprehensive income (loss) as a separate component of stockholders’ equity. Revenues and expenses are translated at the average exchange rates occurring during the respective period. The Company also has pawn operations in El Salvador, where the reporting and functional currency is the U.S. dollar.
Use of Estimates	The preparation of interim financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and related revenue and expenses, and the disclosure of gain and loss contingencies at the date of the financial statements. Such estimates and assumptions are subject to a number of risks and uncertainties, which may cause actual results to differ materially from the Company’s estimates.
Recent Accounting Pronouncements	In October 2023, the FASB issued ASU No 2023-06, “Disclosure Agreements – Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative” (“ASU 2023-06”). ASU 2023-06 will align the disclosure and presentation requirements in the FASB Accounting Standards Codification with the SEC’s regulations. The amendments in ASU 2023-06 will be applied prospectively and are effective when the SEC removes the related requirements from Regulations S-X or S-K. Any amendments the SEC does not remove by June 30, 2027 will not be effective. As the Company is currently subject to these SEC requirements, ASU 2023-06 is not expected to have a material effect on the Company’s current financial position, results of operations or financial statement disclosures. In November 2023, the FASB issued ASU No 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”). ASU 2023-07 expands disclosures about a public entity’s reportable segments and requires more enhanced information about a reportable segment’s expenses, interim segment profit or loss, and how a public entity’s chief operating decision maker uses reported segment profit or loss information in assessing segment performance and allocating resources. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. ASU 2023-07 should be applied retrospectively to all prior periods presented in the financial statements. The Company does not expect ASU 2023-07 to have a material effect on the Company’s current financial position, results of operations or financial statement disclosures. In December 2023, the FASB issued ASU No 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). ASU 2023-09 expands disclosures in the rate reconciliation and requires disclosure of income taxes paid by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. ASU 2023-09 should be applied prospectively; however, retrospective application is permitted. The Company does not expect ASU 2023-09 to have a material effect on the Company’s current financial position, results of operations or financial statement disclosures. In March 2024, the FASB issued ASU No 2024-02, “Codification Improvements - Amendments to Remove References to the Concepts Statements” (“ASU 2024-02”). ASU 2024-02 removes references to various Concepts Statements. In most instances, the references are extraneous and not required to understand or apply the guidance. ASU 2024-02 is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. ASU 2024-02 can be applied prospectively or retrospectively. The Company adopted ASU 2024-02 effective January 1, 2024 on a prospective basis. The adoption of ASU 2024-02 did not have a material effect on the Company’s current financial position, results of operations or financial statement disclosures
Fair Value Measurement	The fair value of financial instruments is determined by reference to various market data and other valuation techniques, as appropriate. Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels. The three fair value levels are (from highest to lowest): Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data.
