Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated balance sheet at December 31, 2015, which is derived from audited financial statements, and the unaudited condensed consolidated financial statements, including the notes thereto, include the accounts of First Cash Financial Services, Inc. and its wholly-owned subsidiaries (together, the “Company”). All significant intercompany accounts and transactions have been eliminated. These unaudited consolidated financial statements are condensed and do not include all disclosures and footnotes required by generally accepted accounting principles in the United States of America for complete financial statements. These interim period financial statements should be read in conjunction with the Company’s consolidated financial statements, which are included in the Company’s annual report on Form 10-K for the year ended December 31, 2015, filed with the Securities and Exchange Commission (the “SEC”) on February 17, 2016. The condensed consolidated financial statements as of June 30, 2016 and 2015, and for the three month and six month periods ended June 30, 2016 and 2015, 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 periods ended June 30, 2016 are not necessarily indicative of the results that may be expected for the full fiscal year. The Company manages its pawn and consumer loan operations under three operating segments: U.S. pawn operations, U.S. consumer loan operations and Latin America pawn and consumer loan operations. The three operating segments have been aggregated into one reportable segment because they have similar economic characteristics and similar long-term financial performance metrics. Additionally, all three segments offer similar and overlapping products and services to a similar customer demographic and are supported by a single, centralized administrative support platform. The Company has significant operations in Mexico and Guatemala to a lesser extent, where the functional currency is the Mexican peso and Guatemalan quetzal, respectively. 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. Revenue and expenses are translated at the average exchange rates occurring during the three month and six month periods ended June 30, 2016. The Company also has operations in El Salvador where the reporting and functional currency is the U.S. dollar.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”). ASU 2014-09 is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the Financial Accounting Standards Board issued ASU No. 2015-14 “Revenue from Contracts with Customers (Topic 606),” which delayed the effective date of ASU 2014-09 by one year. In addition, between March 2016 and May 2016, the Financial Accounting Standards Board issued ASU No. 2016-08, “Revenue from Contracts with Customers - Principal versus Agent Considerations (Reporting revenue gross versus net)” (“ASU 2016-08”), ASU No. 2016-10, “Identifying Performance Obligations and Licensing” (“ASU 2016-10”) and ASU No. 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients” (“ASU 2016-12”). ASU 2016-08, ASU 2016-10 and ASU 2016-12 clarify certain aspects of ASU 2014-09 and provide additional implementation guidance. ASU 2014-09, ASU 2016-08, ASU 2016-10 and ASU 2016-12 become effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2017 for public companies. Early adoption is permitted but not before annual reporting periods beginning after December 15, 2016. Entities are permitted to apply ASU 2014-09, ASU 2016-08, ASU 2016-10 and ASU 2016-12 either retrospectively or through an alternative transition model. The Company is currently assessing the potential impact of ASU 2014-09, ASU 2016-08, ASU 2016-10 and ASU 2016-12 on its consolidated financial statements. In April 2015, the Financial Accounting Standards Board issued ASU No. 2015-03, which requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. In August 2015, the Financial Accounting Standards Board issued ASU No. 2015-15, which clarified the guidance in ASU 2015-03 regarding presentation and subsequent measurement of debt issuance costs related to line-of-credit arrangements. The SEC Staff announced they would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line of credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-03 requires retrospective application and represents a change in accounting principle. ASU 2015-03 became effective for fiscal years beginning after December 15, 2015 and interim periods within those fiscal years. The adoption of ASU 2015-03 resulted in a $3,797,000, $4,436,000 and $4,126,000 decrease in other non-current assets and senior unsecured notes in the accompanying condensed consolidated balance sheets as of June 30, 2016, 2015 and December 31, 2015, respectively. The Company elected to present debt issuance costs related to the Company’s revolving unsecured credit facilities as an asset as allowed in ASU 2015-15. In July 2015, the Financial Accounting Standards Board issued ASU No. 2015-11, “Simplifying the Measurement of Inventory” (“ASU 2015-11”). ASU 2015-11 requires inventory be measured at the lower of cost or net realizable value. ASU 2015-11 defines net realizable value as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Inventory measured using last-in, first-out (“LIFO”) or the retail inventory method are excluded from the scope of this update. ASU 2015-11 requires prospective application and is effective for fiscal years beginning after December 15, 2016 and interim periods within those fiscal years, with early adoption permitted. The Company does not expect ASU 2015-11 to have a material effect on the Company’s current financial position, results of operations or financial statement disclosures. In February 2016, the Financial Accounting Standards Board issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). ASU 2016-02 requires a lessee to recognize, in the statement of financial position, a liability to make lease payments (the lease liability) and a right-to-use asset representing its right to use the underlying asset for the lease term. Leases will be classified as either financing or operating, with classification affecting the pattern of expense recognition in the income statement. Lessor accounting remains largely unchanged. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods, with early adoption permitted. An entity will be required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently assessing the potential impact of ASU 2016-02 on its consolidated financial statements. In March 2016, the Financial Accounting Standards Board issued ASU No. 2016-09, “Compensation-Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). Under ASU 2016-09, companies will no longer record excess tax benefits and certain tax deficiencies in additional paid-in capital (“APIC”). Instead, they will record all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement and the APIC pools will be eliminated. In addition, ASU 2016-09 eliminates the requirement that excess tax benefits be realized before companies can recognize them. ASU 2016-09 also requires companies to present excess tax benefits as an operating activity on the statement of cash flows rather than as a financing activity. Furthermore, ASU 2016-09 will increase the amount an employer can withhold to cover income taxes on awards and still qualify for the exception to liability classification for shares used to satisfy the employer’s statutory income tax withholding obligation. An employer with a statutory income tax withholding obligation will now be allowed to withhold shares with a fair value up to the amount of taxes owed using the maximum statutory tax rate in the employee’s applicable jurisdiction(s). ASU 2016-09 requires a company to classify the cash paid to a tax authority when shares are withheld to satisfy its statutory income tax withholding obligation as a financing activity on the statement of cash flows. Under current GAAP, it was not specified how these cash flows should be classified. In addition, companies will now have to elect whether to account for forfeitures on share-based payments by (1) recognizing forfeitures of awards as they occur or (2) estimating the number of awards expected to be forfeited and adjusting the estimate when it is likely to change, as is currently required. ASU 2016-09 is effective for reporting periods beginning after December 15, 2016, with early adoption permitted. The Company is currently assessing the potential impact of ASU 2016-09 on its consolidated financial statements. In June 2016, the Financial Accounting Standards Board issued ASU No. 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables. ASU 2016-13 is effective for public entities for fiscal years beginning after December 15, 2019, with early adoption permitted. The Company is currently assessing the potential impact of ASU 2016-13 on its consolidated financial statements.
