Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Summary of Significant Accounting Policies and New Accounting Standards	Organization, Summary of Significant Accounting Policies and New Accounting Standards Organization Unless the context requires otherwise, "we", "us", "our", "GreenSky" and "the Company" refer to the business of GreenSky, Inc. and its subsidiaries. "Bank Partners" are defined as federally insured banks that originate loans under the GreenSky program and any other lenders with respect to those loans. We are a leading technology company Powering Commerce at the Point of Sale SM . Our platform is powered by a proprietary technology infrastructure that facilitates merchant sales, while reducing the friction and improving the economics associated with a consumer making a purchase and a bank extending financing for that purchase. It supports the full transaction lifecycle, including credit application, underwriting, real-time allocation to our Bank Partners, document distribution, funding, settlement and servicing. Merchants using our platform, which presently range from small, owner-operated home improvement contractors and healthcare providers to large national home improvement brands and retailers and healthcare service organizations, rely on us to facilitate low or deferred interest promotional point-of-sale financing and payments solutions that enable higher sales volume. Consumers on our platform, who to date primarily have super-prime or prime credit scores, find financing with promotional terms to be an attractive alternative to other forms of payment. Our Bank Partners' access to our proprietary technology solution and merchant network enables them to build a diversified portfolio of high quality consumer loans with attractive risk-adjusted yields with minimal upfront investment. GreenSky, Inc. was formed as a Delaware corporation on July 12, 2017. The Company was formed for the purpose of completing an initial public offering ("IPO") of its Class A common stock and certain Reorganization Transactions, as further described below, in order to carry on the business of GreenSky Holdings, LLC (“GS Holdings”) and its consolidated subsidiaries. GS Holdings, a holding company with no operating assets or operations, was organized in August 2017. On August 24, 2017, GS Holdings acquired a 100% interest in GreenSky, LLC ("GSLLC"), a Georgia limited liability company, which is an operating entity. Common membership interests of GS Holdings are referred to as "Holdco Units." Immediately prior to our IPO, (i) the operating agreement of GS Holdings (the "GS Holdings Agreement") was amended and restated to, among other things, modify its capital structure by replacing the different classes of membership interests and profits interests with Holdco Units; (ii) we issued to each of the Continuing LLC Members (as defined below) a number of shares of GreenSky, Inc. Class B common stock equal to the number of Holdco Units held by it (other than the Holdco Units that were exchanged in connection with the IPO), for consideration in the amount of $0.001 per share of Class B common stock; (iii) certain Holdco Units were contributed to GreenSky, Inc. in exchange for shares of our Class A common stock; (iv) equity holders of the Former Corporate Investors (as defined below) contributed their equity in the Former Corporate Investors to GreenSky, Inc. in exchange for shares of our Class A common stock and the right to certain payments under the Tax Receivable Agreement (“TRA”), and Former Corporate Investors merged with and into subsidiaries of GreenSky, Inc.; (v) outstanding options to acquire Class A units of GS Holdings were equitably adjusted so that they are exercisable for shares of Class A common stock; and (vi) outstanding warrants to acquire Class A units of GS Holdings were equitably adjusted pursuant to their terms so that they are exercisable for Holdco Units (and an equal number of shares of Class B common stock). We refer to these transactions collectively as the “Reorganization Transactions.” Following the Reorganization Transactions, the "Original GS Equity Owners" (other than the Former Corporate Investors) and certain "Original Profits Interests Holders," which we collectively refer to as the "Continuing LLC Members," continue to own Holdco Units. Original GS Equity Owners refers to the owners of units of GS Holdings prior to the Reorganization Transactions. Former Corporate Investors refers to certain of the Original GS Equity Owners that merged with and into one or more subsidiaries of GreenSky, Inc. in connection with the Reorganization Transactions, which was accounted for as a common control transaction and had no material impact on the net assets of the Company. Original Profits Interests Holders refers to the owners of profits interests in GS Holdings prior to the Reorganization Transactions. On May 24, 2018, the Company's Class A common stock commenced trading on the NASDAQ Stock Market in connection with its IPO of 43,700,000 shares of its Class A common stock at a public offering price of $23.00 per share, receiving approximately $954.8 million in net proceeds, after deducting underwriting discounts and commissions (but not including other offering costs), which were used to purchase 2,426,198 shares of Class A common stock and 41,273,802 newly-issued Holdco Units at a price per unit equal to the price per share of Class A common stock sold in the IPO, less underwriting discounts and commissions. The newly-issued Holdco Units were sold by Continuing LLC Members, which we also refer to as "Exchanging Members." Pursuant to an "Exchange Agreement," the Exchanging Members can exchange their Holdco Units (with automatic cancellation of an equal number of shares of Class B common stock) for shares of our Class A common stock on a one -for-one basis, subject to customary adjustments, or for cash (based on the market price of the shares of Class A common stock), at our option (such determination to be made by the disinterested members of our board of directors). The IPO and Reorganization Transactions resulted in the Company becoming the sole managing member of GS Holdings. As the sole managing member of GS Holdings, we operate and control all of GS Holdings’ operations and, through GS Holdings and its subsidiaries, conduct GS Holdings’ business. As of March 31, 2019 , the Company had an economic interest in GS Holdings of 34.0% , after adjusting for unvested units. The Company consolidates the financial results of GS Holdings and reports a noncontrolling interest in its Unaudited Condensed Consolidated Financial Statements representing the GS Holdings interests held by Continuing LLC Members. Summary of Significant Accounting Policies Basis of Presentation The Unaudited Condensed Consolidated Financial Statements were prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") for interim financial statements. We condensed or omitted certain notes and other information from the interim financial statements presented in this Quarterly Report on Form 10-Q. Therefore, these interim statements should be read in conjunction with the GreenSky, Inc. 2018 Form 10-K filed with the SEC on March 15, 2019. In the opinion of management, the Unaudited Condensed Consolidated Financial Statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair statement of our financial condition and results of operations for the interim periods presented. The condensed consolidated balance sheet as of December 31, 2018 , was derived from the audited annual consolidated financial statements, but does not contain all of the footnote disclosures from the annual consolidated financial statements required by United States generally accepted accounting principles ("GAAP"). All intercompany balances and transactions are eliminated upon consolidation. The results for the three months ended March 31, 2019 are not necessarily indicative of results expected for the full year. Use of Estimates The preparation of financial statements in conformity with GAAP requires that management 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 periods. Such estimates and assumptions include, but are not limited to, those that relate to fair value measurements, share-based compensation and income taxes. In developing estimates and assumptions, management uses all available information; however, actual results could materially differ from those estimates and assumptions. Cash and Cash Equivalents and Restricted Cash The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the Unaudited Condensed Consolidated Balance Sheets to the total included within the Unaudited Condensed Consolidated Statements of Cash Flows as of the dates indicated. March 31, 2019 2018 Cash and cash equivalents $ 267,798 $ 277,501 Restricted cash 174,860 141,677 Cash and cash equivalents and restricted cash in Unaudited Condensed Consolidated Statements of Cash Flows $ 442,658 $ 419,178 Revenue Recognition Disaggregated revenue Revenue disaggregated by type of service was as follows for the periods presented: Three Months Ended 2019 2018 Merchant fees $ 74,094 $ 59,365 Interchange fees 9,954 11,575 Transaction fees 84,048 70,940 Servicing fees 19,633 14,331 Other (1) 19 55 Servicing and other 19,652 14,386 Total revenue $ 103,700 $ 85,326 (1) Other revenue includes miscellaneous revenue items that are individually immaterial. Other revenue is presented separately herein in order to clearly present merchant, interchange and servicing fees, which are more integral to our primary operations and better enable financial statement users to calculate metrics such as servicing and merchant fee yields. We have no remaining performance obligations as of March 31, 2019 . No assets were recognized from the costs to obtain or fulfill a contract with a customer as of March 31, 2019 or December 31, 2018 . V olume-based price concessions to merchants and other channel partners that were netted against the gross transaction price were $ 5,908 and $ 4,593 during the three months ended March 31, 2019 and 2018 , respectively. We recognized bad debt expense arising from our contracts with customers of $ 209 and $ 777 during the three months ended March 31, 2019 and 2018 , respectively, which is recorded within general and administrative expense in our Unaudited Condensed Consolidated Statements of Operations. Recently Adopted Accounting Standards Leases In February 2016, the FASB issued ASU 2016-02, which required the recognition of right-of-use ("ROU") assets and lease liabilities for operating leases with terms greater than 12 months on our Unaudited Condensed Consolidated Balance Sheets. Presentation of leases within our Unaudited Condensed Consolidated Statements of Operations and Unaudited Condensed Consolidated Statements of Cash Flows was generally consistent with the prior lease accounting guidance codified in ASC 840, Leases . In July 2018, the FASB issued ASU 2018-11, which provided an additional (and optional) transition method to adopt ASU 2016-02 by applying its provisions at the adoption date and recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption, rather than applying the provisions at the beginning of the earliest period presented in the financial statements. We adopted the standard as of January 1, 2019 with the transition method outlined in ASU 2018-11, recognizing a cumulative-effect adjustment to retained earnings as of that date. Comparative periods continue to be presented and disclosed in accordance with legacy guidance in ASC 840. We applied the practical expedients permitted under the transition guidance outlined in ASU 2018-11, which permitted us to not reassess the following: (i) whether any expired or existing contracts are or contain a lease, (ii) the lease classification for any expired or existing leases, and (iii) initial direct costs for any existing leases. As a result of adopting this standard, we recorded a ROU asset of $ 11.3 million, a lease liability of $ 14.1 million and an immaterial cumulative-effect adjustment to equity as of January 1, 2019. Our adoption of this standard did not have any impact on our Unaudited Condensed Consolidated Statements of Operations. See Note 13 for additional lease disclosures. Improvements to non-employee share-based payment accounting In June 2018, the FASB issued ASU 2018-07 to simplify certain aspects of the accounting for non-employee share-based payment transactions. Under the new standard, all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor's own operations by issuing share-based payment awards are within the scope of ASC 718. Consistent with the accounting requirement for employee share-based payment awards, non-employee share-based payment awards within the scope of ASC 718 are measured at grant-date fair value of the equity instruments, and the requirement to reassess classification of non-employee share-based payment awards upon vesting is eliminated. Our adoption of this standard on January 1, 2019 did not have any impact on our Unaudited Condensed Consolidated Financial Statements. Accounting Standards Issued, But Not Yet Adopted Measurement of credit losses on financial instruments In June 2016, the FASB issued ASU 2016-13, which is intended to better align the timing of recognition of credit losses on financial instruments with management’s expectations. The standard requires a financial asset (or group of financial assets) measured at amortized cost to be presented at the net amount expected to be collected. Management must determine expected credit losses for all financial instruments held at the reporting date based on relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts, the latter of which broadens current guidance. The standard requires enhanced disclosures to help investors and other financial statement users to better understand the significant estimates and judgments used in estimating credit losses. The standard is effective for us on January 1, 2020, with early adoption permitted. The majority of this standard's provisions must be applied using a modified retrospective approach. We are currently evaluating the potential impact of adopting this standard. Customer's accounting for implementation costs incurred in a cloud computing arrangement that is a service contract In August 2018, the FASB issued ASU 2018-15, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, costs for implementation activities in the application development stage are capitalized depending on the nature of the costs, while costs incurred during the preliminary project and post-implementation stages are expensed as the activities are performed. This standard also requires entities to amortize the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement and to apply the existing impairment guidance in ASC 350-40 to the capitalized implementation costs as if the costs were long-lived assets. The standard clarifies that such capitalized implementation costs are also subject to the guidance on abandonment in ASC 360, Property, Plant, and Equipment . In addition, this standard requires alignment in presentation between: (1) the expense related to the capitalized implementation costs and the fees associated with the hosting element (service) of the arrangement on the statement of operations, (2) the capitalized implementation costs and any prepayment for the fees of the associated hosting arrangement on the balance sheet, and (3) the payments for capitalized implementation costs and the payments made for fees associated with the hosting element in the statement of cash flows. The standard is effective for us on January 1, 2020, with early adoption permitted, and should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We are refining our inventory of existing cloud computing arrangements to identify hosting arrangements that are service contracts and will evaluate how to account for the implementation costs of such arrangements.

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share Basic earnings per share of Class A common stock is computed by dividing net income attributable to GreenSky, Inc. by the weighted average number of shares of Class A common stock outstanding during the period. Diluted earnings per share of Class A common stock is computed by dividing net income attributable to GreenSky, Inc., adjusted for the assumed exchange of all potentially dilutive Holdco Units for Class A common stock, by the weighted average number of shares of Class A common stock outstanding adjusted to give effect to potentially dilutive elements. Prior to the IPO, the GS Holdings membership structure included Class A, B, and C Units and Profits Interests. The Company analyzed the calculation of earnings per unit for periods prior to the IPO and determined that it resulted in values that would not be meaningful to the users of these Unaudited Condensed Consolidated Financial Statements. Therefore, earnings per share information has not been presented for the three months ended March 31, 2018 . The following table sets forth reconciliations of the numerators and denominators used to compute basic and diluted earnings per share of Class A common stock for the three months ended March 31, 2019 . Three Months Ended March 31, 2019 Numerator: Income before income tax expense $ 6,806 Less: Net income attributable to noncontrolling interests 4,502 Less: Income tax expense/(benefit) (595 ) Net income attributable to GreenSky, Inc. – basic $ 2,899 Add: Reallocation of net income attributable to noncontrolling interests from the assumed exchange of common units of GS Holdings for Class A common stock 4,502 Less: Income tax expense/(benefit) on reallocation of net income attributable to noncontrolling interests (1) (1,367 ) Net income attributable to GreenSky, Inc. – diluted $ 8,768 Denominator: Weighted average shares of Class A common stock outstanding – basic 57,946,943 Add: Dilutive effects as shown separately below Holdco Units exchangeable for Class A common stock 122,872,400 Class A common stock options 2,918,972 Holdco warrants exchangeable for Class A common stock 328,031 Unvested Class A common stock (2) 126,995 Weighted average shares of Class A common stock outstanding – diluted 184,193,341 Earnings per share of Class A common stock outstanding – basic $ 0.05 Earnings per share of Class A common stock outstanding – diluted (3) $ 0.05 (1) We assumed an effective tax rate of (28.8)% , which represents the effective tax rate on the consolidated GreenSky, Inc. entity inclusive of the income taxes on the portion of GS Holdings' earnings that are attributable to noncontrolling interests. The tax benefit includes the year to date tax benefit of warrant exercises and stock-based compensation deductions. (2) Includes both unvested Class A common stock issued as part of the Reorganization Transactions and unvested Class A common stock awards issued subsequent to the Reorganization Transactions. (3) Our calculation of diluted earnings per share excludes 2,885,041 Class A common stock options, 637,097 unvested Holdco Unit awards and 1,589,999 unvested Class A common stock awards for the three months ended March 31, 2019 , as their inclusion would have been anti-dilutive. These amounts represent the number of instruments outstanding at the end of the period. Application of the treasury stock method would reduce these amounts if they had a dilutive effect and were included in the computation of diluted earnings per share. Shares of the Company’s Class B common stock do not participate in the earnings or losses of the Company and, therefore, are not participating securities. As such, separate presentation of basic and diluted earnings per share of Class B common stock under the two-class method has not been presented.

Fair Value Disclosures [Abstract]
Fair Value of Assets and Liabilities	Fair Value of Assets and Liabilities The following table summarizes, by level within the fair value hierarchy, the carrying amounts and estimated fair values of our assets and liabilities measured at fair value on a recurring or nonrecurring basis or disclosed, but not carried, at fair value in the Unaudited Condensed Consolidated Balance Sheets as of the dates presented. There were no transfers into, out of, or between levels within the fair value hierarchy during any of the periods presented. Refer to Note 4 , Note 7 and Note 8 for additional information on these assets and liabilities. Level March 31, 2019 December 31, 2018 Carrying Fair Value Carrying Fair Value Assets: Cash and cash equivalents (1) 1 $ 267,798 $ 267,798 $ 303,390 $ 303,390 Loan receivables held for sale, net (2) 2 1,999 2,432 2,876 3,552 Liabilities: Finance charge reversal liability (3) 3 $ 149,598 $ 149,598 $ 138,589 $ 138,589 Servicing liabilities (3) 3 3,197 3,197 3,016 3,016 Term loan (1) 2 386,243 395,115 386,822 386,234 (1) Disclosed, but not carried, at fair value. The carrying value of our term loan is net of unamortized debt discount and debt issuance costs. The fair value of our term loan was determined using a discounted cash flow model based on observable market factors (such as changes in credit spreads for comparable benchmark companies) and credit factors specific to us. (2) Measured at fair value on a nonrecurring basis. (3) Measured and carried at fair value on a recurring basis. Servicing liabilities are presented within other liabilities in the Unaudited Condensed Consolidated Balance Sheets. The cash flow impacts of our liabilities that are measured at fair value on a recurring basis are included within net cash provided by operating activities in the Unaudited Condensed Consolidated Statements of Cash Flows. Cash and cash equivalents Cash and cash equivalents are classified within Level 1 of the fair value hierarchy, as the primary component of the price is obtained from quoted market prices in an active market. The carrying amounts of our cash and cash equivalents approximate their fair values due to the short maturities and highly liquid nature of these accounts. Loan receivables held for sale Loan receivables held for sale are recorded in the Unaudited Condensed Consolidated Balance Sheets at the lower of cost or fair value and, therefore, are measured at fair value on a nonrecurring basis. For our loan receivables held for sale, fair value approximates par value, as we have consistently sold loans for the full current balance in historical and current period transactions with our Bank Partners. Loan receivables held for sale are classified within Level 2 of the fair value hierarchy, as the primary component of the price is obtained from observable values of loan receivables with similar terms and characteristics as the loan receivables sold to our Bank Partners. We have the ability to access this market, and it is the market into which these loan receivables are typically sold. Finance charge reversals Our Bank Partners offer certain loan products that have a feature whereby the account holder is provided a promotional period to repay the loan principal balance in full without incurring a finance charge. For these loan products, we bill interest each month throughout the promotional period and, under the terms of the contracts with our Bank Partners, we are obligated to pay this billed interest to the Bank Partners if an account holder repays the loan balance in full within the promotional period. Therefore, the monthly process of billing interest on deferred loan products triggers a potential future finance charge reversal ("FCR") liability for the Company. The FCR component of our Bank Partner contracts qualifies as an embedded derivative. The FCR liability is not designated as a hedge for accounting purposes and, as such, changes in its fair value are recorded within cost of revenue in the Unaudited Condensed Consolidated Statements of Operations. The FCR liability is carried at fair value on a recurring basis in the Unaudited Condensed Consolidated Balance Sheets and is estimated based on historical experience and management’s expectation of future FCR. The FCR liability is classified within Level 3 of the fair value hierarchy, as the primary component of the fair value is obtained from unobservable inputs based on the Company’s data, reasonably adjusted for assumptions that would be used by market participants. The following table reconciles the beginning and ending fair value measurements of our FCR liability during the periods indicated. Three Months Ended 2019 2018 Beginning balance $ 138,589 $ 94,148 Receipts (1) 32,123 28,093 Settlements (2) (59,879 ) (42,838 ) Fair value changes recognized in cost of revenue (3) 38,765 21,510 Ending balance $ 149,598 $ 100,913 (1) Represents cash received from deferred payment loans during the promotional period (referred to as incentive payments), cash received from recoveries on previously charged-off Bank Partner loans, and the proceeds received from transferring our rights to Charged-Off Receivables (as defined below) attributable to previously charged-off Bank Partner loans. We consider all monthly incentive payments from Bank Partners during the period to be related to billed finance charges on deferred interest products until monthly incentive payments exceed total billed finance charges on deferred products, which did not occur during any of the periods presented. (2) Represents the reversal of previously billed finance charges associated with deferred payment loan principal balances that were repaid within the promotional period. (3) A fair value adjustment is made based on the expected reversal percentage of billed finance charges (expected settlements), which is estimated at each reporting date. The fair value adjustment is recognized in cost of revenue in the Unaudited Condensed Consolidated Statements of Operations. Our estimated reversal rate for billed interest on deferred loan products is the significant unobservable input used to value the Level 3 FCR liability. As we have expanded our deferred loan products and as our historical experience with these products has progressed, management has developed more specific reversal rates for categories of deferred loan products based on the length of the interest-free promotional period (ranging from 6 to 24 months), whether or not loan principal payments were required to be paid during the interest-free promotional period, and the industry vertical (home improvement or elective healthcare). This has resulted in incremental increases in the number of reversal rate assumptions used to value the FCR liability. The overall decrease in reversal rates is primarily attributable to lower reversal rate experience on loans within the elective healthcare industry vertical. The following table presents the ranges and weighted averages of our estimated reversal rates as of the dates indicated. Reversal rate March 31, 2019 December 31, 2018 Range 60.0% - 97.0% 70.0% - 97.3% Weighted average 87.8 % 88.2 % The weighted averages in the above table were calculated by first determining the percentage of the reporting date FCR liability attributable to each category of deferred loan products for which a reversal rate assumption is determined. We then multiplied these weights by the unique reversal rate for each category and summed the resulting products. A significant increase or decrease in the estimated reversal rates could result in a significantly higher or lower, respectively, calculation of our expected future payments to our Bank Partners, resulting in a higher or lower, respectively, fair value measurement of our FCR liability. Charged-off receivables Periodically, we transfer our rights to previously charged-off loan receivables ("Charged-Off Receivables") in exchange for a cash payment based on the expected recovery rate of such loan receivables, which consist primarily of previously charged-off Bank Partner loans. We have no continuing involvement with these Charged-Off Receivables other than performing reasonable servicing and collection efforts on behalf of the third parties and Bank Partners that purchased the Charged-Off Receivables. The proceeds from transfers of Charged-Off Receivables attributable to Bank Partner loans are recognized on a collected basis as reductions to cost of revenue, which reduces the fair value adjustment to the FCR liability in the period of transfer. The following table presents details of Charged-Off Receivables transfers during the periods indicated. Aggregate Unpaid Balance Proceeds Bank Partner loans Loan receivables held for sale Total (1) Bank Partner loans Loan receivables held for sale Total Three Months Ended March 31, 2019 $ 53,652 $ 667 $ 54,319 $ 7,355 $ 91 $ 7,446 Three Months Ended March 31, 2018 37,426 1,159 38,585 4,979 154 5,133 (1) During the three months ended March 31, 2019 and 2018 , $5,160 and $3,219 , respectively, of the aggregate unpaid balance on cumulative transferred Charged-Off Receivables were recovered through our servicing efforts on behalf of our Charged-Off Receivables investors. Servicing liabilities We elected the fair value method to account for our servicing liabilities to more appropriately reflect the value of the obligation in our Unaudited Condensed Consolidated Financial Statements. As a result of this election, our servicing liabilities are carried at fair value on a recurring basis within other liabilities in the Unaudited Condensed Consolidated Balance Sheets and are estimated using a discounted cash flow model. Servicing liabilities are classified within Level 3 of the fair value hierarchy, as the primary component of the fair value is obtained from unobservable inputs based on peer market data, reasonably adjusted for assumptions that would be used by market participants to service our transferred Charged-Off Receivables portfolios, for which market data is not available. Changes in the fair value of our servicing liabilities are recorded within other gains/(losses) in the Unaudited Condensed Consolidated Statements of Operations. Significant assumptions used in valuing our servicing liabilities were as follows: • Cost of servicing: The cost of servicing represents the servicing rate a willing market participant would require to service loans with similar characteristics as the Charged-Off Receivables. • Discount rate: The discount rate reflects the time value of money adjusted for a risk premium and is within an observable range based on peer market data. • Recovery period: Our recovery period was determined based on a reasonable recovery period for loans of these sizes and characteristics based on historical experience. We assumed that collection efforts for these loans will cease after five years, and the run-off of the portfolio will follow a straight-line methodology, adjusted for actual cash recoveries over time. The following table reconciles the beginning and ending fair value measurements of our servicing liabilities associated with transferring our rights to Charged-Off Receivables during the periods presented. Three Months Ended 2019 2018 Beginning balance $ 3,016 $ 2,071 Initial obligation from transfer of Charged-Off Receivables (1) 651 461 Fair value changes recognized in other gains/(losses) Change in inputs or assumptions used in the valuation model — — Other changes in fair value (1)(2) (470 ) (345 ) Ending balance $ 3,197 $ 2,187 (1) Recognized in other gains/(losses) in the Unaudited Condensed Consolidated Statements of Operations. (2) Represents the reduction of our servicing liabilities due to the passage of time and collection of loan payments. The following table presents quantitative information about the significant unobservable inputs used to value the Level 3 servicing liabilities as of the dates presented. Input March 31, 2019 December 31, 2018 Range Weighted Average Range Weighted Average Cost of servicing (basis points) 62.5 62.5 62.5 62.5 Discount rate 18.0 % 18.0 % 18.0 % 18.0 % Recovery period (years) 3.3 - 4.9 4.3 3.6 - 4.9 4.3 The recovery period is weighted by the unpaid balance of previously transferred Charged-Off Receivables as of March 31, 2019 and December 31, 2018 . The recovery period reflects the length of time over which we expect to perform servicing activities and has an inverse correlation with the amount by which the servicing liability is reduced each reporting period. As such, a significant increase or decrease in the expected recovery period could have resulted in higher or lower, respectively, servicing liabilities. A significant increase or decrease in the market cost of servicing could have resulted in significantly higher or lower, respectively, servicing liabilities as of March 31, 2019 and December 31, 2018 . We only use one cost of servicing assumption; therefore, the weighted average only includes a singular basis points cost of servicing. Finally, a significant increase or decrease in the discount rate could have resulted in lower or higher, respectively, servicing liabilities as of March 31, 2019 and December 31, 2018 . The discount rate impact on our servicing liabilities is much less compared to the recovery period and cost of servicing assumptions. We only use one discount rate assumption; therefore, the weighted average only includes a singular discount rate. Financial Guarantee Under the terms of the contracts with our Bank Partners, we provide limited protection in the event of excessive Bank Partner portfolio credit losses and record a financial guarantee liability at fair value based on historical experience and the amount of current customer delinquencies expected to convert into Bank Partner portfolio credit losses. See Note 13 for additional information.

Debt Disclosure [Abstract]
Borrowings	Borrowings Credit Agreement In August 2017, we entered into a $450.0 million credit agreement (“Credit Agreement”), which provided for a $350.0 million term loan (“original term loan”) maturing on August 25, 2024 and a $100.0 million revolving loan facility maturing on August 25, 2022. The net proceeds from the term loan of $338.6 million , along with $7.9 million of cash, were set aside for a subsequent $346.5 million payment (which is occurring in stages) to certain equity holders and a related party. With the exception of the payments to the related party, which are related party expenses, the payments were accounted for as distributions. During the three months ended March 31, 2019 , we made distributions of $ 1.0 million and no payments to the related party. The remaining reserved payment of $4.5 million as of March 31, 2019 was included within other liabilities and related party liabilities in the Unaudited Condensed Consolidated Balance Sheets. As of March 31, 2019 and December 31, 2018 , we had no borrowings under the revolving loan facility. Amended Credit Agreement In March 2018, we amended certain terms of our Credit Agreement ("Amended Credit Agreement"). The term loan and revolving loan facility under the Amended Credit Agreement are collectively referred to as the "Credit Facility." The Amended Credit Agreement replaced the original term loan with a $400.0 million term loan (“modified term loan”) and extended the maturity date to March 29, 2025. Further, the interest margin on the modified term loan was reduced to 3.25% per annum. We contemporaneously settled the outstanding principal balance on the original term loan of $349.1 million with the issuance of the $400.0 million modified term loan. The net proceeds from the modified term loan were used to provide for distributions to certain equity holders and a related party prior to the Company's IPO. During the three months ended March 31, 2019 , we made distributions of $ 0.2 million and no payments to the related party. The remaining reserved payment of $1.6 million as of March 31, 2019 was included within other liabilities and related party liabilities in the Unaudited Condensed Consolidated Balance Sheets. See Note 14 for further discussion of related party transactions. When our first lien net leverage ratio is above 1.50 to 1.00 , we are subject to a quarterly commitment fee at a per annum rate of 0.50% on the daily unused amount of the revolving loan facility, inclusive of the aggregate amount available to be drawn under letters of credit, of which $10.0 million was available, but unused, as of March 31, 2019 . This rate is reduced to 0.375% for any quarterly period in which our first lien net leverage ratio is equal to or below 1.50 to 1.00 . During the three months ended March 31, 2019 and 2018 , we recognized $94 and $125 , respectively, of commitment fees within interest expense in the Unaudited Condensed Consolidated Statements of Operations. Key details of the term loan are as follows: March 31, 2019 December 31, 2018 Term loan, face value (1) $ 396,000 $ 397,000 Unamortized debt discount (2) (3,574 ) (3,728 ) Unamortized debt issuance costs (2) (6,183 ) (6,450 ) Term loan $ 386,243 $ 386,822 (1) The principal balance of the term loan is scheduled to be repaid on a quarterly basis at an amortization rate of 0.25% per quarter through December 31, 2024, with the balance due at maturity. (2) For the three months ended March 31, 2019 and 2018 , debt discount of $154 and $128 , respectively, and debt issuance costs of $267 and $289 , respectively, were amortized into interest expense in the Unaudited Condensed Consolidated Statements of Operations. Covenants We were in compliance with all covenants, both financial and non-financial, as of March 31, 2019 and December 31, 2018 . The Amended Credit Agreement defines events of default, the breach of which could require early payment of all borrowings under, and termination of, the Amended Credit Agreement or similar actions. Any borrowings under the Amended Credit Agreement are unconditionally guaranteed by our subsidiaries. Further, the lenders have a security interest in substantially all of the assets of GS Holdings and the other guarantors thereunder.

Noncontrolling Interest [Abstract]
Noncontrolling Interests	Noncontrolling Interests GreenSky, Inc. is the sole managing member of GS Holdings and consolidates the financial results of GS Holdings. Therefore, the Company reports a noncontrolling interest based on the common units of GS Holdings held by the Continuing LLC Members. Changes in GreenSky, Inc.’s ownership interest in GS Holdings, while GreenSky, Inc. retains its controlling interest in GS Holdings, are accounted for as equity transactions. As such, future redemptions or direct exchanges of Holdco Units by the Continuing LLC Members will result in a change in ownership and reduce or increase the amount recorded as noncontrolling interest and increase or decrease additional paid-in capital when GS Holdings has positive or negative net assets, respectively. As of March 31, 2019 , GreenSky, Inc. had 62,151,547 shares of Class A common stock outstanding, which resulted in an equivalent amount of ownership of Holdco Units. Adjusted for unvested Holdco Units, GreenSky, Inc. had a 34.0% economic ownership interest in GS Holdings as of March 31, 2019 .

Income Taxes

Income Taxes	3 Months Ended
	Mar. 31, 2019
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes GreenSky, Inc. is taxed as a corporation and pays corporate federal, state and local taxes on income allocated to it from GS Holdings based upon GreenSky, Inc.’s economic interest held in GS Holdings. GS Holdings is treated as a pass-through partnership for income tax reporting purposes. GS Holdings’ members, including GreenSky, Inc., are liable for federal, state and local income taxes based on their share of GS Holdings’ pass-through taxable income. The Company’s effective tax rate for the three months ended March 31, 2019 was (8.7)% , and the Company recorded $595 of income tax benefit for the three months ended March 31, 2019 . The Company’s effective tax rate for the three months ended March 31, 2019 was less than our combined federal and state statutory tax rate of 23.7% , primarily because the Company is not liable for income taxes on the portion of GS Holdings’ earnings that are attributable to noncontrolling interests. Further, the effective tax rate for the three months ended March 31, 2019 includes the tax effect of warrant exercises and stock-based compensation deductions, which are required to be recorded discretely in the interim period in which those items occur. The effective tax rate is dependent on many factors, including the estimated amount of income subject to income tax; therefore, the effective tax rate can vary from period to period. Prior to the Reorganization Transactions, GS Holdings' earnings were completely exempt from federal corporate income taxation. The results from the three months ended March 31, 2018 do not reflect income tax expense because, prior to the Reorganization Transactions, the consolidated GS Holdings pass-through entity was not subject to federal income tax. As of March 31, 2019 and December 31, 2018 , the total liability related to uncertain tax positions was $3.4 million and $3.4 million, respectively. The Company recognizes interest and penalties, if applicable, related to uncertain tax positions as a component of income tax expense. Accrued interest and penalties were immaterial as of March 31, 2019 , and therefore did not impact the effective income tax rate. The Company anticipates that the liability for unrecognized tax benefits could decrease by up to $3.4 million within the next twelve months due to the Company filing a non-automatic method change with the Internal Revenue Service. Deferred tax assets, net of $337.8 million and $307.0 million as of March 31, 2019 and December 31, 2018 , respectively, relate primarily to the basis difference in our investment in GS Holdings. This basis difference arose primarily as a result of the Reorganization Transactions, the IPO and subsequent exchanges of Class B common stock for Class A common stock. As of March 31, 2019 , we concluded based on the weight of all available positive and negative evidence that all of our deferred tax assets are more likely than not to be realized. As such, no additional valuation allowance was recognized. Tax Receivable Agreement Pursuant to our election under Section 754 of the Internal Revenue Code (the "Code"), we expect to obtain an increase in our share of the tax basis in the net assets of GS Holdings when Holdco Units are redeemed or exchanged by the Continuing LLC Members of GS Holdings. We intend to treat any redemptions and exchanges of Holdco Units as direct purchases of Holdco Units for U.S. federal income tax purposes. These increases in tax basis may reduce the amounts that we would otherwise pay in the future to various tax authorities. They may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets. On May 23, 2018, we entered into a tax receivable agreement ("TRA") that provides for the payment by us of 85% of the amount of any tax benefits that we actually realize, or in some cases are deemed to realize, as a result of (i) increases in our share of the tax basis in the net assets of GS Holdings resulting from any redemptions or exchanges of Holdco Units and from our acquisition of the equity of certain of the Former Corporate Investors, (ii) tax basis increases attributable to payments made under the TRA, and (iii) deductions attributable to imputed interest pursuant to the TRA (the "TRA Payments"). We expect to benefit from the remaining 15% of any tax benefits that we may actually realize. The TRA Payments are not conditioned upon any continued ownership interest in GS Holdings or us. The rights of each member of GS Holdings that is a party to the TRA are assignable to transferees of their respective Holdco Units. The timing and amount of aggregate payments due under the TRA may vary based on a number of factors, including the timing and amount of taxable income generated by the Company each year, as well as the tax rate then applicable. As of March 31, 2019 , the Company had a liability of $ 286.6 million related to its projected obligations under the TRA, which is captioned as tax receivable agreement liability in our Unaudited Condensed Consolidated Balance Sheets. During the three months ended March 31, 2019 , we did not make any payments, inclusive of interest, to members of GS Holdings pursuant to the TRA.

Commitments, Contingencies and

Commitments, Contingencies and Guarantees	3 Months Ended
	Mar. 31, 2019
Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Guarantees	Commitments, Contingencies and Guarantees Commitments Leases As discussed in Note 1 , we adopted the provisions of ASU 2016-02 as of January 1, 2019. Periods subsequent to this adoption date are presented and disclosed in accordance with ASC 842, Leases, while comparative periods continue to be presented and disclosed in accordance with legacy guidance in ASC 840, Leases. In accordance with ASC 842, we determine if an arrangement is or contains a lease at inception of the contract. A contract is or contains a lease if the contract conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. We primarily lease our premises under multi-year, non-cancelable operating leases. Operating leases are included in operating lease ROU assets and operating lease liabilities in our Unaudited Condensed Consolidated Balance Sheets. As of March 31, 2019 , we did not have any finance leases. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU assets are increased by any prepaid lease payments and are reduced by any unamortized lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Base rent is subject to rent escalations on each annual anniversary from the lease commencement dates. Lease expense for lease payments, including any step rent provisions specified in the lease agreements, is recognized on a straight-line basis over the lease term and is included within property, office and technology and related party expenses in the Unaudited Condensed Consolidated Statements of Operations. Lease expense was $811 and $744 for the three months ended March 31, 2019 and 2018 , respectively. See Note 14 for additional information regarding office space leased from a related party. Our operating leases have terms expiring from 2021 through 2024, exclusive of renewal option periods. Our leases contain renewal option periods ranging from five to fifteen years from the expiration dates. One lease also contains a termination option in 2023. These options were not recognized as part of our operating lease ROU assets and operating lease liabilities, as we did not conclude at the commencement date of the leases that we were reasonably certain to exercise these options. However, in our normal course of business, we expect our leases to be renewed, amended or replaced by other leases. As of March 31, 2019 , we had operating leases for expanded premises to existing leases that had not yet commenced. These operating leases will commence during 2019 with lease terms of approximately three to five years. As applicable, these leases also extend the terms of the existing leases to run coterminously with the expanded premises. The future undiscounted lease payments for these leases total approximately $3,587 . The components of lease expense and supplemental cash flow information related to our operating leases were as follows for the period indicated. Three Months Ended Lease expense Operating lease cost $ 811 Cash paid for amounts included in the measurement of operating lease liabilities Operating cash flows from operating leases $ 956 Supplemental balance sheet information related to our operating leases was as follows as of the date indicated. March 31, 2019 Operating lease ROU assets $ 10,657 Operating lease liabilities 13,325 Weighted average remaining lease term (in years) 3.9 Weighted average discount rate 5.7 % For the periods presented, maturities of operating lease liabilities as of the date indicated and a reconciliation of the total undiscounted cash flows to the operating lease liabilities in the Unaudited Condensed Consolidated Balance Sheets, were as follows in accordance with ASC 842: March 31, 2019 Remainder of 2019 $ 2,594 2020 3,813 2021 3,904 2022 2,926 2023 1,238 Thereafter 542 Total lease payments $ 15,017 Less: imputed interest (1,692 ) Operating lease liabilities $ 13,325 Future minimum lease payments under leases entered into as of the date indicated (inclusive of leases that had not yet commenced) were as follows for the years presented in accordance with ASC 840: December 31, 2018 2019 $ 3,871 2020 4,073 2021 4,173 2022 3,087 2023 1,238 Thereafter 542 Total minimum lease payments $ 16,984 Covenants Our transaction processor and some Bank Partners impose financial covenants upon our wholly owned subsidiary, GSLLC. As of March 31, 2019 and December 31, 2018 , GSLLC was in compliance with all financial covenants. See Note 7 to the Unaudited Condensed Consolidated Financial Statements for discussion of financial and non-financial covenants associated with our borrowings. Other Commitments As of March 31, 2019 and December 31, 2018 , the outstanding open and unused line of credit on approved loan receivables held for sale was $2.4 million and $ 3.0 million, respectively, for which we did not record a provision in the Unaudited Condensed Consolidated Financial Statements. For certain Bank Partners, we maintain a restricted cash balance based on a contractual percentage of the total interest billed on outstanding deferred interest loans that are within the promotional period less previous FCR on such outstanding loans. As of March 31, 2019 and December 31, 2018 , restricted cash in the Unaudited Condensed Consolidated Balance Sheets includes $56.4 million and $49.8 million, respectively, associated with these arrangements. Contingencies In limited instances, the Company may be subject to operating losses if we make certain errors in managing credit programs and we determine that a customer is not liable for a loan originated by a Bank Partner. We evaluated this contingency in accordance with ASC 450, Contingencies , and determined that it is reasonably possible that losses could result from errors in underwriting. However, in management’s opinion, it is not possible to estimate the likelihood or range of reasonably possible future losses related to errors in underwriting based on currently available information. Therefore, we have not established a liability for this loss contingency. Further, from time to time, we place Bank Partner loans on non-accrual and non-payment status (“Pended Status”) while we investigate consumer loan balance inquiries, which may arise from disputed charges related to work performed by third-party merchants. As of March 31, 2019 , Bank Partner loan balances in Pended Status were $16.5 million . While it is management’s expectation that most of these loan balance inquiries will be resolved without incident, in certain instances we may determine that it is appropriate for the Company to permanently reverse the loan balance and assume the economic responsibility for the loan balance itself. We record a liability for these instances. As of March 31, 2019 , our liability for potential Pended Status future losses was $5.5 million . Legal Proceedings From time to time, we may become a party to civil claims and lawsuits in the ordinary course of business. IPO Litigation The Company and certain of its officers and directors, together with certain underwriters of the Company’s IPO, were named in six putative class actions filed in the Supreme Court of the State of New York, all of which actions have been consolidated (In Re GreenSky, Inc. Securities Litigation (Consolidated Action), Index No. 655626/2018 (N.Y. Sup. Ct.) (the “State Case”)), and in two putative class actions filed in the United States District Court for the Southern District of New York, both of which actions also have been consolidated (In Re GreenSky, Inc. Securities Litigation (Consolidated Action), Case No. 1:2018-cv-11071-PAE (S.D.N.Y.) (the “Federal Case” and, together with the State Case, the “Consolidated Cases”)). The Company and its officers and directors named in the Consolidated Cases intend to defend themselves vigorously in all respects in regard thereto. Under certain circumstances, the Company may be obligated to indemnify some or all of the other defendants in the Consolidated Cases. As the Company has not determined the likelihood of loss with respect to the Consolidated Cases to be probable, the Company has not recorded any liability as of March 31, 2019 with respect to either of such actions. It is our policy to recognize legal fees as they are incurred when legal services are provided within general and administrative expense in our Unaudited Condensed Consolidated Statements of Operations. As it relates to ongoing legal proceedings, we estimate the aggregate range of reasonably possible losses in excess of amounts previously recognized and inclusive of additional potential legal fees to be up to approximately $4.6 million. Financial Guarantees Under the terms of the contracts with our Bank Partners, a contractual percentage of the Bank Partners’ monthly originations and month-end outstanding portfolio balance is held and maintained in restricted, interest-bearing escrow accounts to serve as limited protection to the Bank Partners in the event of excess Bank Partner portfolio credit losses. The Company’s maximum exposure to Bank Partner portfolio credit losses is limited to the contractual restricted cash balance, which was $102.4 million as of March 31, 2019 . The recorded fair value of the financial guarantee related to these contracts was $1.3 million as of March 31, 2019 , which was recorded within other liabilities in the Unaudited Condensed Consolidated Balance Sheets. Recorded financial guarantees are typically settled within one year of the initial measurement of the liabilities. In determining the measured liabilities, we consider a variety of factors, including historical experience and management’s expectations of current customer delinquencies converting into Bank Partner portfolio losses. We do not expect to directly recover any losses associated with this financial guarantee.

Related Party Transactions

Related Party Transactions	3 Months Ended
	Mar. 31, 2019
Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Leases We lease office space from a related party under common management control for which lease expense is recognized within related party expenses in the Unaudited Condensed Consolidated Statements of Operations and for which operating lease right-of-use assets and operating lease liabilities are recognized within those respective line items in the Unaudited Condensed Consolidated Balance Sheets. Total operating lease expense related to this office space was $437 and $372 for the three months ended March 31, 2019 and 2018 , respectively. Operating lease ROU assets and operating lease liabilities related to this office space were $ 6.2 million and $ 7.2 million, respectively, as of March 31, 2019 . Contractual and Other Arrangements In August 2018, we entered into an agreement in which an unrelated third party acted as a placement agent in connection with certain Charged-Off Receivables transfers and received a fee from us based on the proceeds received from such transfers. In performing these services, the third party agreed to use an affiliate of a member of the Board of Directors and, as such, we determined this arrangement to be related party in nature. In December 2018, the unrelated third party assigned its role in the agreement to the affiliate entity itself; therefore, the arrangement remains a related party transaction. We incurred expenses related to this arrangement of $ 99 during the three months ended March 31, 2019 , which is presented within related party expenses in the Unaudited Condensed Consolidated Statements of Operations. There is no payable related to this arrangement as of March 31, 2019 and December 31, 2018 . We entered into non-interest bearing loan agreements with certain non-executive employees for which the remaining outstanding balances are forgiven ratably over designated periods based on continual employment with the Company. As of March 31, 2019 and December 31, 2018 , the remaining outstanding balances on these loan agreements were $125 and $142 , respectively, which are presented within related party receivables in the Unaudited Condensed Consolidated Balance Sheets. There were no equity-based payments to non-employees that resulted in related party expenses during the three months ended March 31, 2019 and 2018 . Distributions In May 2018, we declared a special operating distribution of $26.2 million, which resulted in a related party payable of $1.2 million. The unpaid portion of the related party distribution of $0.2 million was recorded within related party liabilities in the Unaudited Condensed Consolidated Balance Sheets as of March 31, 2019 and will be paid in stages upon vesting events. In May 2018, we used the net proceeds from the issuance of our modified term loan to provide for distributions to certain equity holders and a related party prior to the Company's IPO. During the three months ended March 31, 2019 , we made no payments to the related party. The unpaid portion of the related party reserved payment of $ 0.1 million was recorded within related party liabilities in the Unaudited Condensed Consolidated Balance Sheets as of March 31, 2019 . In August 2017, we incurred fees of $2.6 million due to an affiliate of one of the members of the board of managers in connection with finalizing our August 2017 term loan transaction. These costs were not directly attributable to the original term loan and were, therefore, expensed as incurred rather than deferred against the term loan balance. The unpaid portion of these fees of $0.5 million as of March 31, 2019 , were recorded within related party liabilities in the Unaudited Condensed Consolidated Balance Sheets. Financing Partner Arrangement In June 2018, the outstanding receivables owned by affiliates of two members of our current Board of Directors pursuant to a November 2016 agreement were sold to a Bank Partner, which is not a related party, and continue to be serviced by us. In connection with that receivable sale, the related party financing partners ended this servicing agreement with us. As of March 31, 2019 and December 31, 2018 , we no longer have any such related party arrangements. Unaudited Condensed Consolidated Statements of Operations effects associated with our related party financing partners were as follows during the period indicated. Three Months Ended March 31, 2018 Servicing and other $ 28 Related party expenses (1) 211 (1) Expenses incurred related to related party financing partner credit losses.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities Upon completion of our IPO, GreenSky, Inc. became the managing member of GS Holdings with 100% of the management and voting power in GS Holdings. In its capacity as managing member, GreenSky, Inc. has the sole authority to make decisions on behalf of GS Holdings and bind GS Holdings to agreements. Further, GS Holdings maintains separate capital accounts for its investors as a mechanism for tracking earnings and subsequent distribution rights. Accordingly, management concluded that GS Holdings is a limited partnership or similar legal entity as contemplated in ASC 810, Consolidation . Further, management concluded that GreenSky, Inc. is GS Holdings' primary beneficiary based on two conditions. First, GreenSky, Inc., in its capacity as managing member with sole voting rights, has the power to direct the activities of GS Holdings that most significantly impact its economic performance, including selecting, terminating and setting the compensation of management responsible for implementing GS Holdings' policies and procedures, as well as establishing the strategic, operating and capital decisions of GS Holdings in the ordinary course of business. Second, GreenSky, Inc. has an obligation to absorb potential losses of GS Holdings or the right to receive potential benefits from GS Holdings in proportion to its equity interest, which was 34.0% as of March 31, 2019 , after adjusting for unvested Holdco Units. Management considers this exposure to be significant to GS Holdings. As the primary beneficiary, GreenSky, Inc. consolidates the results of GS Holdings for financial reporting purposes under the variable interest consolidation model guidance in ASC 810. GreenSky, Inc.’s relationship with GS Holdings results in no recourse to the general credit of GreenSky, Inc. GS Holdings and its consolidated subsidiaries represent GreenSky, Inc.’s sole investment. GreenSky, Inc. shares in the income and losses of GS Holdings in direct proportion to GreenSky, Inc.’s ownership percentage. Further, GreenSky, Inc. has no contractual requirement to provide financial support to GS Holdings. Below are tabular disclosures that provide insight into how GS Holdings affects GreenSky, Inc.’s financial position, performance and cash flows. Prior to the IPO and Reorganization Transactions, GreenSky, Inc. did not have any variable interest in GS Holdings.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Unless the context requires otherwise, "we", "us", "our", "GreenSky" and "the Company" refer to the business of GreenSky, Inc. and its subsidiaries. "Bank Partners" are defined as federally insured banks that originate loans under the GreenSky program and any other lenders with respect to those loans. We are a leading technology company Powering Commerce at the Point of Sale SM . Our platform is powered by a proprietary technology infrastructure that facilitates merchant sales, while reducing the friction and improving the economics associated with a consumer making a purchase and a bank extending financing for that purchase. It supports the full transaction lifecycle, including credit application, underwriting, real-time allocation to our Bank Partners, document distribution, funding, settlement and servicing. Merchants using our platform, which presently range from small, owner-operated home improvement contractors and healthcare providers to large national home improvement brands and retailers and healthcare service organizations, rely on us to facilitate low or deferred interest promotional point-of-sale financing and payments solutions that enable higher sales volume. Consumers on our platform, who to date primarily have super-prime or prime credit scores, find financing with promotional terms to be an attractive alternative to other forms of payment. Our Bank Partners' access to our proprietary technology solution and merchant network enables them to build a diversified portfolio of high quality consumer loans with attractive risk-adjusted yields with minimal upfront investment. GreenSky, Inc. was formed as a Delaware corporation on July 12, 2017. The Company was formed for the purpose of completing an initial public offering ("IPO") of its Class A common stock and certain Reorganization Transactions, as further described below, in order to carry on the business of GreenSky Holdings, LLC (“GS Holdings”) and its consolidated subsidiaries. GS Holdings, a holding company with no operating assets or operations, was organized in August 2017. On August 24, 2017, GS Holdings acquired a 100% interest in GreenSky, LLC ("GSLLC"), a Georgia limited liability company, which is an operating entity. Common membership interests of GS Holdings are referred to as "Holdco Units." Immediately prior to our IPO, (i) the operating agreement of GS Holdings (the "GS Holdings Agreement") was amended and restated to, among other things, modify its capital structure by replacing the different classes of membership interests and profits interests with Holdco Units; (ii) we issued to each of the Continuing LLC Members (as defined below) a number of shares of GreenSky, Inc. Class B common stock equal to the number of Holdco Units held by it (other than the Holdco Units that were exchanged in connection with the IPO), for consideration in the amount of $0.001 per share of Class B common stock; (iii) certain Holdco Units were contributed to GreenSky, Inc. in exchange for shares of our Class A common stock; (iv) equity holders of the Former Corporate Investors (as defined below) contributed their equity in the Former Corporate Investors to GreenSky, Inc. in exchange for shares of our Class A common stock and the right to certain payments under the Tax Receivable Agreement (“TRA”), and Former Corporate Investors merged with and into subsidiaries of GreenSky, Inc.; (v) outstanding options to acquire Class A units of GS Holdings were equitably adjusted so that they are exercisable for shares of Class A common stock; and (vi) outstanding warrants to acquire Class A units of GS Holdings were equitably adjusted pursuant to their terms so that they are exercisable for Holdco Units (and an equal number of shares of Class B common stock). We refer to these transactions collectively as the “Reorganization Transactions.” Following the Reorganization Transactions, the "Original GS Equity Owners" (other than the Former Corporate Investors) and certain "Original Profits Interests Holders," which we collectively refer to as the "Continuing LLC Members," continue to own Holdco Units. Original GS Equity Owners refers to the owners of units of GS Holdings prior to the Reorganization Transactions. Former Corporate Investors refers to certain of the Original GS Equity Owners that merged with and into one or more subsidiaries of GreenSky, Inc. in connection with the Reorganization Transactions, which was accounted for as a common control transaction and had no material impact on the net assets of the Company. Original Profits Interests Holders refers to the owners of profits interests in GS Holdings prior to the Reorganization Transactions. On May 24, 2018, the Company's Class A common stock commenced trading on the NASDAQ Stock Market in connection with its IPO of 43,700,000 shares of its Class A common stock at a public offering price of $23.00 per share, receiving approximately $954.8 million in net proceeds, after deducting underwriting discounts and commissions (but not including other offering costs), which were used to purchase 2,426,198 shares of Class A common stock and 41,273,802 newly-issued Holdco Units at a price per unit equal to the price per share of Class A common stock sold in the IPO, less underwriting discounts and commissions. The newly-issued Holdco Units were sold by Continuing LLC Members, which we also refer to as "Exchanging Members." Pursuant to an "Exchange Agreement," the Exchanging Members can exchange their Holdco Units (with automatic cancellation of an equal number of shares of Class B common stock) for shares of our Class A common stock on a one -for-one basis, subject to customary adjustments, or for cash (based on the market price of the shares of Class A common stock), at our option (such determination to be made by the disinterested members of our board of directors). The IPO and Reorganization Transactions resulted in the Company becoming the sole managing member of GS Holdings. As the sole managing member of GS Holdings, we operate and control all of GS Holdings’ operations and, through GS Holdings and its subsidiaries, conduct GS Holdings’ business. As of March 31, 2019 , the Company had an economic interest in GS Holdings of 34.0% , after adjusting for unvested units. The Company consolidates the financial results of GS Holdings and reports a noncontrolling interest in its Unaudited Condensed Consolidated Financial Statements representing the GS Holdings interests held by Continuing LLC Members.
Basis of Presentation	Basis of Presentation The Unaudited Condensed Consolidated Financial Statements were prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") for interim financial statements. We condensed or omitted certain notes and other information from the interim financial statements presented in this Quarterly Report on Form 10-Q. Therefore, these interim statements should be read in conjunction with the GreenSky, Inc. 2018 Form 10-K filed with the SEC on March 15, 2019. In the opinion of management, the Unaudited Condensed Consolidated Financial Statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair statement of our financial condition and results of operations for the interim periods presented. The condensed consolidated balance sheet as of December 31, 2018 , was derived from the audited annual consolidated financial statements, but does not contain all of the footnote disclosures from the annual consolidated financial statements required by United States generally accepted accounting principles ("GAAP"). All intercompany balances and transactions are eliminated upon consolidation. The results for the three months ended March 31, 2019 are not necessarily indicative of results expected for the full year.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires that management 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 periods. Such estimates and assumptions include, but are not limited to, those that relate to fair value measurements, share-based compensation and income taxes. In developing estimates and assumptions, management uses all available information; however, actual results could materially differ from those estimates and assumptions.
Recently Adopted Accounting Standards and Accounting Standards Issued but Not Yet Adopted	Recently Adopted Accounting Standards Leases In February 2016, the FASB issued ASU 2016-02, which required the recognition of right-of-use ("ROU") assets and lease liabilities for operating leases with terms greater than 12 months on our Unaudited Condensed Consolidated Balance Sheets. Presentation of leases within our Unaudited Condensed Consolidated Statements of Operations and Unaudited Condensed Consolidated Statements of Cash Flows was generally consistent with the prior lease accounting guidance codified in ASC 840, Leases . In July 2018, the FASB issued ASU 2018-11, which provided an additional (and optional) transition method to adopt ASU 2016-02 by applying its provisions at the adoption date and recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption, rather than applying the provisions at the beginning of the earliest period presented in the financial statements. We adopted the standard as of January 1, 2019 with the transition method outlined in ASU 2018-11, recognizing a cumulative-effect adjustment to retained earnings as of that date. Comparative periods continue to be presented and disclosed in accordance with legacy guidance in ASC 840. We applied the practical expedients permitted under the transition guidance outlined in ASU 2018-11, which permitted us to not reassess the following: (i) whether any expired or existing contracts are or contain a lease, (ii) the lease classification for any expired or existing leases, and (iii) initial direct costs for any existing leases. As a result of adopting this standard, we recorded a ROU asset of $ 11.3 million, a lease liability of $ 14.1 million and an immaterial cumulative-effect adjustment to equity as of January 1, 2019. Our adoption of this standard did not have any impact on our Unaudited Condensed Consolidated Statements of Operations. See Note 13 for additional lease disclosures. Improvements to non-employee share-based payment accounting In June 2018, the FASB issued ASU 2018-07 to simplify certain aspects of the accounting for non-employee share-based payment transactions. Under the new standard, all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor's own operations by issuing share-based payment awards are within the scope of ASC 718. Consistent with the accounting requirement for employee share-based payment awards, non-employee share-based payment awards within the scope of ASC 718 are measured at grant-date fair value of the equity instruments, and the requirement to reassess classification of non-employee share-based payment awards upon vesting is eliminated. Our adoption of this standard on January 1, 2019 did not have any impact on our Unaudited Condensed Consolidated Financial Statements. Accounting Standards Issued, But Not Yet Adopted Measurement of credit losses on financial instruments In June 2016, the FASB issued ASU 2016-13, which is intended to better align the timing of recognition of credit losses on financial instruments with management’s expectations. The standard requires a financial asset (or group of financial assets) measured at amortized cost to be presented at the net amount expected to be collected. Management must determine expected credit losses for all financial instruments held at the reporting date based on relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts, the latter of which broadens current guidance. The standard requires enhanced disclosures to help investors and other financial statement users to better understand the significant estimates and judgments used in estimating credit losses. The standard is effective for us on January 1, 2020, with early adoption permitted. The majority of this standard's provisions must be applied using a modified retrospective approach. We are currently evaluating the potential impact of adopting this standard. Customer's accounting for implementation costs incurred in a cloud computing arrangement that is a service contract In August 2018, the FASB issued ASU 2018-15, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, costs for implementation activities in the application development stage are capitalized depending on the nature of the costs, while costs incurred during the preliminary project and post-implementation stages are expensed as the activities are performed. This standard also requires entities to amortize the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement and to apply the existing impairment guidance in ASC 350-40 to the capitalized implementation costs as if the costs were long-lived assets. The standard clarifies that such capitalized implementation costs are also subject to the guidance on abandonment in ASC 360, Property, Plant, and Equipment . In addition, this standard requires alignment in presentation between: (1) the expense related to the capitalized implementation costs and the fees associated with the hosting element (service) of the arrangement on the statement of operations, (2) the capitalized implementation costs and any prepayment for the fees of the associated hosting arrangement on the balance sheet, and (3) the payments for capitalized implementation costs and the payments made for fees associated with the hosting element in the statement of cash flows. The standard is effective for us on January 1, 2020, with early adoption permitted, and should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We are refining our inventory of existing cloud computing arrangements to identify hosting arrangements that are service contracts and will evaluate how to account for the implementation costs of such arrangements.

The tax benefit includes the year to date tax benefit of warrant exercises and stock-based compensation deductions. (2) Includes both unvested Class A common stock issued as part of the Reorganization Transactions and unvested Class A common stock awards issued subsequent to the Reorganization Transactions. (3) Our calculation of diluted earnings per share excludes 2,885,041 Class A common stock options, 637,097 unvested Holdco Unit awards and 1,589,999 unvested Class A common stock awards for the three months ended March 31, 2019 , as their inclusion would have been anti-dilutive. These amounts represent the number of instruments outstanding at the end of the period. Application of the treasury stock method would reduce these amounts if they had a dilutive effect and were included in the computation of diluted earnings per share.

We retain servicing arrangements on sold loan receivables with the same terms and conditions as loans that are originated by our Bank Partners. Income from loan receivables held for sale activities is recorded within interest income and other gains/(losses) in the Unaudited Condensed Consolidated Statements of Operations. On March 27, 2019, we sold loan receivables held for sale to a Bank Partner in the amount of $63,673 . We had no sales of loan receivables held for sale during the three months ended March 31, 2018. (2) We temporarily hold certain loan receivables, which are originated by a Bank Partner, while non-originating Bank Partner eligibility is being determined. Once we determine that a loan receivable meets the investment requirements of an eligible Bank Partner, we transfer the loan receivable to the Bank Partner at cost plus any accrued interest. The reported amount also includes loan receivables that have been placed on non-accrual and non-payment status while we investigate consumer inquiries. (3) We received recovery payments of $9 and $17 during the three months ended March 31, 2019 and 2018 , respectively. Recoveries of principal and finance charges and fees on previously written off loan receivables held for sale are recognized on a collected basis as other gains and interest income, respectively, in the Unaudited Condensed Consolidated Statements of Operations. Separately, during the three months ended March 31, 2019 and 2018 , write offs and other were reduced by $91 and $154 , respectively, related to cash proceeds received from transferring our rights to Charged-Off Receivables attributable to loan receivables held for sale.
