Accounting Policies [Abstract]
Description of Business	Description of Business Aaron's, Inc. (the "Company") is a leading omnichannel provider of lease-purchase solutions. As of June 30, 2018, the Company's operating segments are Progressive Leasing, Aaron's Business and DAMI. Progressive Leasing is a virtual lease-to-own company that provides lease-purchase solutions in 46 states and the District of Columbia. It does so by purchasing merchandise from third-party retailers desired by those retailers' customers and, in turn, leasing that merchandise to the customers through a lease-to-own transaction. Progressive Leasing consequently has no stores of its own, but rather offers lease-purchase solutions to the customers of traditional retailers. The Aaron's Business offers furniture, consumer electronics, home appliances and accessories to consumers primarily with a month-to-month, lease-to-own agreement with no credit needed through the Company's Aaron's-branded stores in the United States and Canada and e-commerce website. This operating segment also supports franchisees of its Aaron's-branded stores. In addition, the Aaron's Business segment also includes the operations of Woodhaven Furniture Industries, which manufactures and supplies the majority of the upholstered furniture and bedding leased and sold in Company-operated and franchised stores. DAMI partners with merchants to provide a variety of revolving credit products originated through two third-party federally insured banks to customers that may not qualify for traditional prime lending (called "second-look" financing programs). The Company acquired the store operations of five franchisees during the six months ended June 30, 2018 and four franchisees during the year ended December 31, 2017, which included the Company's largest franchisee. The Company acquired the store operations of three additional franchisees in July 2018. Refer to Note 2 and Note 8 to these condensed consolidated financial statements for additional discussion on these franchisee acquisitions.
Basis of Presentation	Basis of Presentation The preparation of the Company's condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information requires management to make estimates and assumptions that affect the amounts reported in these financial statements and accompanying notes. Actual results could differ from those estimates. Generally, actual experience has been consistent with management's prior estimates and assumptions. Management does not believe these estimates or assumptions will change significantly in the future absent unidentified and unforeseen events. The accompanying unaudited condensed consolidated financial statements do not include all information required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included in the accompanying unaudited condensed consolidated financial statements. These financial statements should be read in conjunction with the financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017 (the "2017 Annual Report") filed with the U.S. Securities and Exchange Commission on March 1, 2018. The results of operations for the three and six months ended June 30, 2018 are not necessarily indicative of operating results for the full year.
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of Aaron's, Inc. and its subsidiaries, each of which is wholly owned. Intercompany balances and transactions between consolidated entities have been eliminated.
Accounting Policies and Estimates	Accounting Policies and Estimates See Note 1 to the consolidated financial statements in the 2017 Annual Report.
Earnings Per Share	Earnings Per Share Earnings per share is computed by dividing net earnings by the weighted average number of shares of common stock outstanding during the period. The computation of earnings per share assuming dilution includes the dilutive effect of stock options, restricted stock units ("RSUs"), restricted stock awards ("RSAs") and performance share units ("PSUs") (collectively, "share-based awards") as determined under the treasury stock method.
Revenue Recognition	Revenue Recognition Lease Revenues and Fees The Company provides merchandise, consisting of furniture, consumer electronics, computers, appliances and household accessories, to its customers for lease under certain terms agreed to by the customer. The Company's Aaron's Business stores offer leases with month-to-month terms that can be renewed up to 12, 18 or 24 months. The Company's Progressive Leasing segment offers virtual lease-purchase solutions, typically over 12 months, to the customers of traditional retailers. The Company does not require deposits upon inception of customer agreements. The customer has the right to acquire ownership either through a purchase option or through payment of all required lease payments. Aaron's Business lease revenues are recognized as revenue net of related sales taxes in the month they are due. Lease payments received prior to the month due are recorded as deferred lease revenue, and this amount is included in customer deposits and advance payments in the accompanying condensed consolidated balance sheets. Progressive Leasing lease revenues are earned prior to the lease payment due date and are recorded net of related sales taxes as earned. Revenue recorded prior to the payment due date results in unbilled accounts receivable in the accompanying condensed consolidated balance sheets. All of the Company's customer agreements are considered operating leases. The Company maintains ownership of the lease merchandise until all payment obligations are satisfied under sales and lease ownership agreements. Initial direct costs related to Progressive Leasing's lease purchase agreements are capitalized as incurred and amortized over the estimated lease term. The capitalized costs have been classified within prepaid expenses and other assets in the accompanying consolidated balance sheets. Initial direct costs related to Aaron's Business customer agreements are expensed as incurred and have been classified as operating expenses in the Company's consolidated statements of earnings. The statement of earnings effects of expensing the initial direct costs of the Aaron's Business as incurred are not materially different from amortizing initial direct costs over the lease term. Retail and Non-Retail Sales Revenues from the sale of merchandise to franchisees are recognized when control transfers to the franchisee, which is upon its receipt of the merchandise. Revenues from the sale of merchandise to other customers are recognized at the time of shipment, at which time control is transferred to the customer. Substantially all of the amounts reported as non-retail sales and non-retail cost of sales in the accompanying condensed consolidated statements of earnings relate to the sale of lease merchandise to franchisees. The Company classifies the sale of merchandise to other customers as retail sales in the consolidated statements of earnings. Franchise Royalties and Fees The Company franchises its Aaron's stores in markets where the Company has no immediate plans to enter. Franchisees pay an ongoing royalty of 6% of the weekly cash revenue collections, which is recognized as the fees become due. In addition, franchisees typically pay a non-refundable initial franchise fee from $15,000 to $50,000 depending upon market size. Franchise fees and area development fees are generated from the sale of rights to develop, own and operate sales and lease ownership stores and pre-opening services provided by Aaron's to assist in the start-up operations of the stores. The Company considers the rights to the intellectual property and the pre-opening services to be a single performance obligation, resulting in the recognition of revenue ratably over time from the store opening date throughout the remainder of the franchise agreement term. The Company believes that this period of time is most representative of the time period in which the customer realizes the benefits of having the right to access the Company's intellectual property. The deferred revenue balance related to initial franchise fees is $2.3 million as of June 30, 2018 and is included in customer deposits and advance payments on the condensed consolidated balance sheets. Revenue related to initial franchise fees recognized during the three and six months ended June 30, 2018 was $0.2 million and $0.5 million respectively. The Company guarantees certain debt obligations of some of the franchisees and receives guarantee fees based on the outstanding debt obligations of such franchisees. The Company recognizes finance fee revenue as the guarantee obligation is satisfied. Refer to Note 5 of these condensed consolidated financial statements for additional discussion of the Company's franchise-related guarantee obligation. The Company also charges fees for advertising efforts that benefit the franchisees. Such fees are recognized at the time the advertising takes place and are presented as franchise royalties and fees in the Company's condensed consolidated statements of earnings. Initial direct costs related to the pre-opening services provided to franchisees are immaterial and are expensed as incurred. These expenses have been classified as operating expenses in the Company's condensed consolidated statements of earnings.
Interest and Fees on Loans Receivable	Interest and Fees on Loans Receivable DAMI extends or declines credit to an applicant through its bank partners based upon the applicant's credit rating and other factors. Qualifying applicants receive a credit card to finance their initial purchase and to use in subsequent purchases at the merchant or other participating merchants for an initial 24-month period, which DAMI may renew if the cardholder remains in good standing. DAMI acquires the loan receivable from merchants through its third-party bank partners at a discount from the face value of the loan. The discount is comprised of a merchant fee discount and a promotional fee discount. The merchant fee discount represents a pre-negotiated, nonrefundable discount that generally ranges from 3% to 25% of the loan face value. The discount is designed to cover the risk of loss related to the portfolio of cardholder charges and DAMI's direct origination costs. The merchant fee discount and origination costs are netted on the condensed consolidated balance sheet in loans receivable. Cardholders generally have an initial 24-month period that the card is active. The merchant fee discount, net of the origination costs, is amortized on a net basis and is recorded as interest and fee revenue on loans receivable in the condensed consolidated statements of earnings on a straight-line basis over the initial 24-month period. The discount from the face value of the loan on the acquisition of the loan receivable from the merchant through the third-party bank partners also includes a promotional fee discount, which generally ranges from 1% to 8%. The promotional fee discount is intended to compensate the holder of the loan receivable (e.g. DAMI) for deferred or reduced interest rates that are offered to the cardholder for a specified period on the outstanding loan balance (generally for six, 12 or 18 months). The promotional fee discount is amortized as interest and fee revenue on loans receivable in the condensed consolidated statements of earnings on a straight-line basis over the promotional interest period (i.e., over six, 12 or 18 months, depending on the promotion). The unamortized promotional fee discount is netted on the condensed consolidated balance sheet in loans receivable. The customer is required to make periodic minimum payments of at least 3.5% of the outstanding loan balance, which includes outstanding interest. Fixed and variable interest rates, typically 25% to 34.99%, are compounded daily for cards that do not qualify for deferred or reduced interest promotional periods. Interest income, which is recognized based upon the amount of the loans outstanding, is recognized as interest and fees on loans receivable in the billing period in which they are assessed if collectability is reasonably assured. For credit cards that provide for deferred or reduced interest, if the balance is not paid off during the promotional period, interest is billed to the customers at standard rates and the cumulative amount owed is charged to the cardholder account in the month that the promotional period expires or defaults. The Company recognizes interest revenue during the promotional period based on its historical experience related to cardholders that fail to pay off balances during the promotional period. Annual fees are charged to cardholders at the commencement of the loan and on each subsequent anniversary date. Annual fees are deferred and recognized into revenue on a straight-line basis over a one year period. Under the provisions of the credit card agreements, the Company also may assess fees for service calls or for missed or late payments, which are recognized as revenue in the billing period in which they are assessed if collectability is reasonably assured.
Investments	Investments At December 31, 2017, investments classified as held-to-maturity securities consisted of British pound-denominated notes issued by PerfectHome, which is based in the U.K. The PerfectHome Notes ("Notes") consisted of outstanding principal and accrued interest of £15.1 million ($20.4 million) at December 31, 2017. PerfectHome was a variable interest entity ("VIE") because it did not have sufficient equity at risk. However, the Company was not the primary beneficiary and did not consolidate PerfectHome since the Company lacked power through voting or similar rights to direct the activities that most significantly affected PerfectHome's economic performance. During the three months ended June 30, 2018, PerfectHome's liquidity deteriorated significantly due to continuing operating losses and the senior lender's decision to no longer provide additional funding under a secured revolving debt agreement resulting from PerfectHome's default of certain covenants. Additionally, the senior lender notified PerfectHome in May 2018 of its intent to exercise remedies available under its credit documentation, which included the right to call its outstanding debt. Furthermore, during the three months ended June 30, 2018, the U.K. governing authority for rent-to-own companies, the Financial Conduct Authority, proposed new regulatory measures which could adversely affect PerfectHome's business. In July 2018, PerfectHome entered into the U.K.’s insolvency process and was subsequently acquired by the senior lender. The Company believes it will not receive any further payments on its subordinated secured Notes. As a result, the Company recorded a full impairment of the PerfectHome investment of $20.1 million during the three months ended June 30, 2018.
Accounts Receivable	Accounts Receivable Accounts receivable consist primarily of receivables due from customers of Progressive Leasing and Company-operated stores, corporate receivables incurred during the normal course of business (primarily for real estate leasing activities and vendor consideration) and franchisee obligations.
Lease Merchandise	Lease Merchandise The Company's lease merchandise consists primarily of furniture, consumer electronics, home appliances and accessories and is recorded at the lower of cost or net realizable value. The cost of merchandise manufactured by our Woodhaven Furniture Industries operations is recorded at cost and includes overhead from production facilities, shipping costs and warehousing costs. The Company-operated stores begin depreciating merchandise at the earlier of twelve months and one day or when the item is leased and depreciate merchandise to a 0% salvage value over the lease agreement period when on lease, generally 12 to 24 months, and generally 36 months when not on lease. The Company's Progressive Leasing segment, at which substantially all merchandise is on lease, depreciates merchandise generally over 12 months. Depreciation is accelerated upon early payout. The Company's policies require weekly lease merchandise counts at its store-based operations, which include write-offs for unsalable, damaged, or missing merchandise inventories. In addition to monthly cycle counting, full physical inventories are generally taken at the fulfillment and manufacturing facilities annually and appropriate provisions are made for missing, damaged and unsalable merchandise. In addition, the Company monitors lease merchandise levels and mix by division, store, and fulfillment center, as well as the average age of merchandise on hand. If obsolete lease merchandise cannot be returned to vendors, its carrying amount is adjusted to its net realizable value or written off. All lease merchandise is available for lease or sale. On a monthly basis, all damaged, lost or unsalable merchandise identified is written off. The Company records a provision for write-offs on the allowance method, which estimates the merchandise losses incurred but not yet identified by management as of the end of the accounting period based on historical write-off experience. The provision for write-offs is included in operating expenses in the accompanying condensed consolidated statements of earnings.
Loans Receivable, Net	Loans Receivable, Net Gross loans receivable represents the principal balances of credit card charges at DAMI's participating merchants that remain outstanding to cardholders, plus unpaid interest and fees due from cardholders. The allowances and unamortized fees represents an allowance for uncollectible amounts; merchant fee discounts, net of capitalized origination costs; promotional fee discounts; and deferred annual card fees. Loans acquired in the October 15, 2015 DAMI acquisition (the "Acquired Loans") were recorded at their estimated fair value at the acquisition date. The projected net cash flows from expected payments of principal, interest, fees and servicing costs and anticipated charge-offs were included in the determination of fair value; therefore, an allowance for loan losses and an amount for unamortized fees were not recognized for the Acquired Loans. The difference, or discount, between the expected cash flows to be received and the fair value of the Acquired Loans is accreted to interest and fees on loans receivable based on the effective interest method. At each period end, the Company evaluates the appropriateness of the accretable discount on the Acquired Loans based on actual and revised projected future cash receipts. Losses on loans receivable are recognized when they are incurred, which requires the Company to make its best estimate of probable losses inherent in the portfolio. The Company evaluates loans receivable collectively for impairment. The method for calculating the best estimate of probable losses takes into account the Company's historical experience, adjusted for current conditions and the Company's judgment concerning the probable effects of relevant observable data, trends and market factors. Economic conditions and loan performance trends are closely monitored to manage and evaluate exposure to credit risk. Trends in delinquency ratios are an indicator of credit risk within the loans receivable portfolio, including the migration of loans between delinquency categories over time. Charge-off rates represent another indicator of the potential for future credit losses. The risk in the loans receivable portfolio is correlated with broad economic trends, such as unemployment rates, gross domestic product growth and gas prices, which can have a material effect on credit performance. To the extent that actual results differ from estimates of uncollectible loans receivable, the Company's results of operations and liquidity could be materially affected. The Company calculates the allowance for loan losses based on actual delinquency balances and historical average loss experience on loans receivable by aging category for the prior eight quarters. The allowance for loan losses is maintained at a level considered adequate to cover probable losses of principal, interest and fees on active loans in the loans receivable portfolio. The adequacy of the allowance is evaluated at each period end. Delinquent loans receivable are those that are 30 days or more past due based on their contractual billing dates. The Company places loans receivable on nonaccrual status when they are greater than 90 days past due or upon notification of cardholder bankruptcy, death or fraud. The Company discontinues accruing interest and fees and amortizing merchant fee discounts and promotional fee discounts for loans receivable in nonaccrual status. Loans receivable are removed from nonaccrual status when cardholder payments resume, the loan becomes 90 days or less past due and collection of the remaining amounts outstanding is deemed probable. Payments received on nonaccrual loans are allocated according to the same payment hierarchy methodology applied to loans that are accruing interest. Loans receivable are charged off at the end of the month following the billing cycle in which the loans receivable become 120 days past due. DAMI extends or declines credit to an applicant through its bank partners based upon the applicant's credit rating and other factors.
Assets Held for Sale	Assets Held for Sale Certain properties, consisting of parcels of land and commercial buildings, met the held for sale classification criteria as of June 30, 2018 and December 31, 2017. Assets held for sale are recorded at the lower of their carrying value or fair value less estimated cost to sell and are classified within prepaid expenses and other assets in the condensed consolidated balance sheets. Depreciation is suspended on assets upon classification to held for sale. The carrying amount of the properties held for sale as of June 30, 2018 and December 31, 2017 is $9.7 million and $10.1 million, respectively. The Company estimated the fair values of real estate properties using the market values for similar properties. These properties are considered Level 2 assets as defined below.
Fair Value Measurement	Fair Value Measurement Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To increase the comparability of fair value measures, the following hierarchy prioritizes the inputs to valuation methodologies used to measure fair value: Level 1—Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2—Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3—Valuations based on unobservable inputs reflecting the Company's own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. The Company measures assets held for sale at fair value on a nonrecurring basis and records impairment charges when they are deemed to be impaired. The Company maintains certain financial assets and liabilities, and fixed-rate long-term debt, that are not measured at fair value but for which fair value is disclosed. The fair values of the Company's other current financial assets and liabilities, including cash and cash equivalents, accounts receivable and accounts payable, approximate their carrying values due to their short-term nature. The fair value for the loans receivable, net of allowances, and the revolving credit borrowings also approximate their carrying amounts.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted Revenue Recognition. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("Topic 606"). ASU 2014-09 replaces substantially all existing revenue recognition guidance with a single, comprehensive revenue recognition model that requires a company to recognize revenue to depict the transfer of promised goods and services to customers at the amount to which it expects to be entitled in exchange for transferring those goods or services. On January 1, 2018, the Company adopted Topic 606 using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning on January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under Topic 605. The standard changed the timing of recognition of store pre-opening revenue from franchisees. Previously, the Company's accounting policy was to recognize initial franchise store pre-opening revenue when earned, which is generally when a new store opens. Under the new standard, the initial franchise pre-opening services are not considered distinct from the continuing franchise services as they would not transfer a benefit to the franchisee directly without use of the franchise license and should be bundled with the franchise license as a single performance obligation. As a result, the pre-opening revenues will be recognized from the store opening date over the remaining life of the franchise license term. The standard also changed the presentation of certain fees charged to franchisees, primarily advertising fees. Previously, there was diversity in practice and advertising fees charged to franchisees were recorded as a reduction to advertising expense, which is classified within operating expenses in the consolidated statements of earnings. The new standard resulted in the presentation of advertising fees charged to franchisees to be reported as franchise royalties and fee revenue in the consolidated statements of earnings, instead of a reduction to advertising expense. The changes associated with the adoption of Topic 606 will not require significant changes to controls and procedures around the revenue recognition process. The Company adopted the standard on January 1, 2018 using the modified retrospective approach and recorded a pre-tax adjustment to opening retained earnings and deferred revenue of $2.4 million on January 1, 2018. The Company expects to recognize such amounts in revenue over an average of the next 5 years. Business Combinations. In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business. The objective of the update is to add guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The Company prospectively adopted this ASU in the first quarter of 2018. The new standard results in certain store acquisitions (or disposals) which do not transfer a substantive process to be accounted for as asset acquisitions (or disposals). The Company has identified a separate "expanded customer base" intangible asset, which is separately valued and recorded in asset acquisitions. The "expanded customer base" represents the estimated fair value of the acquisition purchase price paid by the Company for the ability to advertise and execute lease agreements with a larger pool of customers in the respective markets. This intangible asset was previously subsumed in goodwill under the business combinations accounting guidance. In situations in which the purchase price exceeds the fair value of the assets acquired, any remaining economic goodwill is allocated on a relative fair value basis to all acquired assets, including merchandise inventory. In situations in which the fair value of the assets acquired exceeds the purchase price, the acquisition is treated as a bargain purchase with the excess allocated on a relative fair value basis to all assets. This results in the recognition of the initial asset bases at less than fair value, including merchandise inventory. The Company routinely enters into arrangements to acquire lease merchandise inventory and the related customer lease agreements of a store; however, the arrangement does not transfer a substantive process. Under ASU 2017-01, these acquisitions result in all of the purchase price getting assigned to definite lived assets, instead of a portion going to goodwill. This results in higher depreciation and amortization expense under the new standard for asset acquisitions that would have been accounted for as business combinations under the prior guidance. Transactions that are now accounted for as asset disposals, instead of business disposals, do not result in the write-off of goodwill as part of the disposal. The new standard did not have a material impact to the Company's condensed consolidated financial statements during the first six months of 2018. The future impact of this new standard will depend on the quantity and magnitude of future acquisitions (or disposals) that will be treated as asset acquisitions (or disposals) in accordance with ASU 2017-01. Pending Adoption Leases. In February 2016, the FASB issued ASU 2016-02, Leases, which would require lessees to recognize assets and liabilities for most leases and would change certain aspects of today's lessor accounting, among other things. ASU 2016-02 is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. Companies must use a modified retrospective approach to adopt ASU 2016-02. A majority of the Company's revenue generating activities will be within the scope of ASU 2016-02. The Company has preliminarily determined that the new standard will not materially impact the timing of revenue recognition. The new standard will result in the Company classifying bad debt expense incurred within its Progressive Leasing segment as a reduction of lease revenue and fees within the consolidated statements of earnings. The new standard will also impact the Company as a lessee by requiring substantially all of its operating leases to be recognized on the balance sheet as a right-to-use asset and lease liability. The Company plans to elect a package of optional practical expedients which includes the option to retain the current classification of leases entered into prior to January 1, 2019, and thus does not anticipate a material impact to the consolidated statements of earnings or consolidated statements of cash flows. The Company expects to be affected by the transition guidance related to recognition of deferred gains recorded under previous sale and operating leaseback transactions, which requires companies to recognize any deferred gains not resulting from off-market terms as a cumulative-effect adjustment to retained earnings upon adoption of ASU 2016-02. The Company is currently quantifying the impacts of its operating leases to the consolidated financial statements, as well as evaluating other impacts of adopting ASU 2016-02, and intends to adopt the new standard in the first quarter of 2019. Financial Instruments - Credit Losses. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments. The main objective of the update is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by companies at each reporting date. For trade and other receivables, held to maturity debt securities and other instruments, companies will be required to use a new forward-looking "expected losses" model that generally will result in the recognition of allowances for losses earlier than under current accounting guidance. The standard will be adopted on a prospective basis with a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019, with early adoption permitted. The Company has not yet determined the potential effects of adopting ASU 2016-13 on its consolidated financial statements.
