Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements and footnotes have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") as contained in the Financial Accounting Standards Board (‘‘FASB’’) Accounting Standards Codification (“ASC”) for interim financial information. All intercompany transactions and accounts have been eliminated in consolidation. The results of operations for the three and nine months ended September 30, 2015 are not necessarily indicative of the results for the full year or the results for any future periods. We have reclassified certain prior-period amounts to conform to the current period’s presentation. These unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements, including the related notes, and the other information contained in our Annual Report on Form 10-K for the year ended December 31, 2014 . When used in these notes to condensed consolidated financial statements, the terms "we," "us," "our" or similar terms refers to On Deck Capital, Inc. and its consolidated subsidiaries. In the second quarter of 2015, we acquired a 55% interest in On Deck Capital Australia PTY LTD ("OnDeck Australia") with the remaining 45% owned by non-affiliated parties. In the third quarter of 2015, we acquired a 67% interest in Lancelot QBFOD LLC with the remaining 33% owned by Intuit Inc. ("Intuit"). We have entered into the transaction involving OnDeck Australia with local partners to facilitate providing financing products to small businesses in Australia. We and Intuit jointly invested in Lancelot QBFOD LLC to provide integrated access to line of credit financing to Intuit customers utilizing Intuit's customer data. We consolidate the financial position and results of operations of OnDeck Australia and Lancelot QBFOD LLC. The noncontrolling interest, which is presented as a separate component of our consolidated equity, represents the minority owners' proportionate share of the equity of the jointly owned entities. The noncontrolling interest is adjusted for the minority owners' share of the earnings, losses, investments and distributions. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts in the condensed consolidated financial statements and accompanying notes. Significant estimates include allowance for loan losses, valuation of warrants, stock-based compensation expense, servicing assets/liabilities, capitalized software development costs, the useful lives of long-lived assets and valuation allowance for deferred tax assets. We base our estimates on historical experience, current events and other factors we believe to be reasonable under the circumstances. These estimates and assumptions are inherently subjective in nature; actual results may differ from these estimates and assumptions. Loans and Loans Held for Sale Loans We originate term loans and lines of credit (collectively, “loans”) that are generally short term in nature and require daily or weekly repayments. We have both the ability and intent to hold these loans to maturity. When we originate a term loan, the borrower grants us a security interest in its assets. We may or may not perfect our security interest by publicly filing a financing statement. Loans are carried at amortized cost, reduced by a valuation allowance for loan losses estimated as of the balance sheet dates. In accordance with ASC Subtopic 310-20, Nonrefundable Fees and Other Costs , the amortized cost of a loan is equal to the unpaid principal balance, plus net deferred origination costs. Net deferred origination costs are comprised of certain direct origination costs, net of all loan origination fees received. Loan origination fees include fees charged to the borrower related to origination that increase the loan’s effective interest yield. Direct origination costs in excess of loan origination fees received are included in the loan balance and amortized over the term of the loan using the effective interest method. Loan origination costs are limited to direct costs attributable to originating a loan, including commissions and personnel costs directly related to the time spent by those individuals performing activities related to loan origination. Additionally, when a term loan is originated in conjunction with the extinguishment of a previously issued term loan, also known as a renewal, we determine whether this is a new loan or a modification to an existing loan in accordance with ASC 310-20. If accounted for as a new loan, any remaining unamortized net deferred costs are recognized when the new loan is originated. Further, when a renewal is accounted for as a new loan, the cash flows of the origination and related net deferred origination costs of that new loan are presented as operating cash outflows on the Statement of Cash Flows if the renewal is designated to be sold or as investing cash outflows if the renewal is designated to be held for investment. If a renewal is accounted for as a modification, any remaining unamortized net deferred costs are amortized over the life of the modified loan. Further, when a renewal is accounted for as a modification, the additional cash flows associated with the origination and related net deferred origination costs of that modification are presented on the Statement of Cash Flows within the same section as the originally issued term loan prior to renewal. Loans Held for Sale OnDeck Marketplace ® is a program whereby we originate and sell certain term loans to third-party institutional investors and retain servicing rights. We sell these whole loans to purchasers in exchange for a cash payment. A portion of our loans are originated for the purpose of being sold through OnDeck Marketplace . These whole loans are initially classified as held for sale within a short period of time from the initial funding when the whole loan is identified for sale and a plan exists for the sale. A loan that is initially designated as held for sale or held for investment may be reclassified when our intent for that loan changes. When a loan held for sale is reclassified to held for investment, the loan is recorded at amortized costs and an appropriate provision for loan loss is recorded. When a loan held for investment is reclassified to held for sale, any allowance for loan loss related to that loan will be released. Loans held for sale, inclusive of net deferred origination costs, are recorded at the lower of amortized cost or fair value until the loans are sold or reclassified. Servicing Rights We service loans that we have sold to third parties and upon such sale, we may recognize a servicing asset or liability, collectively referred to as servicing rights. Receiving more than adequate compensation, as defined by ASC Topic 860 Transfers and Servicing , results in the recognition of a servicing asset. Receiving less than adequate compensation results in a servicing liability. Servicing assets and liabilities are recorded at fair value and are presented as a component of other assets or accrued expenses and other liabilities, respectively. The initial recognition of a servicing asset results in a corresponding increase to gain on sales of loans. The initial recognition of a servicing liability results in a corresponding decrease to gain on sales of loans. Subsequent adjustments to the fair value of servicing rights are recognized as an adjustment to other revenue. We utilize industry-standard modeling, such as discounted cash flow models, to arrive at an estimate of fair value and may utilize independent service providers to assist in the valuation process. Significant assumptions used in valuing our servicing rights are as follows: • Adequate compensation: We estimate adequate compensation as the rate a willing market participant would require to service loans with similar characteristics as those in the serviced portfolio. In the event of a lack of transparency and quantity of transactions related to trades of servicing rights of comparable loans (i.e., loans with comparable terms, unpaid principal balances, renewal rates and default rates) we may consider the actual cost incurred as an appropriate proxy for what a market participant would require to service the loans. • Discount rate: For servicing rights on loans, the discount rate reflects the time value of money and a risk premium intended to reflect the amount of compensation market participants would require. • Renewal rate: We estimate the timing and probability that a borrower may renew their loan in advance of scheduled repayment, thus reducing the projected unpaid principal balance and expected term of the loan, which are used to project future servicing revenues. • Default rate: We estimate the timing and probability of loan defaults and write-offs, thus reducing the projected unpaid principal balance and expected term of the loan, which are used to project future servicing revenues. Allowance for Loan Losses The allowance for loan losses (“ALLL”) is established through periodic charges to the provision for loan losses. Loan losses are charged against the ALLL when we believe that the future collection of principal is unlikely. Subsequent recoveries, if any, are credited to the ALLL. We evaluate the creditworthiness of our portfolio on a pooled basis due to its composition of small, homogeneous loans with similar general credit risk characteristics and diversification among variables including industry and geography. We use a proprietary forecast loss rate at origination for new loans that have not had the opportunity to make payments when they are first funded. The forecasted loss rate is updated daily to reflect actual loan performance, and the underlying ALLL model is updated monthly to reflect our assumptions. The allowance is subjective as it requires material estimates, including such factors as historical trends, known and inherent risks in the loan portfolio, adverse situations that may affect borrowers’ ability to repay and current economic conditions. Other qualitative factors considered may include items such as uncertainties in forecasting and modeling techniques, changes in portfolio composition, seasonality, business conditions and emerging trends. Recovery of the carrying value of loans is dependent to a great extent on conditions that may be beyond our control. Any combination of the aforementioned factors may adversely affect our loan portfolio resulting in increased delinquencies and loan losses and could require additional provisions for credit losses, which could impact future periods. In our opinion, we have provided adequate allowances to absorb probable credit losses inherent in our loan portfolio based on available and relevant information affecting the loan portfolio at each balance sheet date. Accrual for Unfunded Loan Commitments and Off-Balance Sheet Credit Exposures For our line of credit product we estimate probable losses on unfunded loan commitments similarly to the ALLL process and include the calculated amount in accrued expenses and other liabilities. We believe the accrual for unfunded loan commitments is sufficient to absorb estimated probable losses related to these unfunded credit commitments. The determination of the adequacy of the accrual is based on evaluations of the unfunded credit commitments, including an assessment of the probability of commitment usage, credit risk factors for lines of credit outstanding to these customers and the terms and expiration dates of the unfunded credit commitments. As of September 30, 2015 and December 31, 2014 , our off-balance sheet credit exposure related to the undrawn line of credit balances was $65.1 million and $28.7 million , respectively. The related accrual for unfunded loan commitments was $3.2 million and $1.3 million as of September 30, 2015 and December 31, 2014 , respectively. Net adjustments to the accrual for unfunded loan commitments are included in general and administrative expenses. Accrual for Third-Party Representations We have made certain representations to third parties that purchase loans through OnDeck Marketplace . There are no restricted assets related to the underlying loan sale agreements. Any significant estimated post-sale obligations or contingent obligations to the purchaser of the loans, such as fraudulent loan repurchase obligations or excess loss indemnification obligations, would be accrued if probable and estimable in accordance with ASC 450, Contingencies . As of September 30, 2015 and December 31, 2014 , we have recorded a liability of $0.3 million and $0 , respectively, related to estimated post-sale obligations. Revenue Recognition Interest Income We generate revenue primarily through interest and origination fees earned on loans originated and held to maturity. We recognize interest and origination fee revenue over the terms of the underlying loans using the effective interest method. Origination fees collected but not yet recognized as revenue are netted with direct origination costs and presented as a component of loans in our condensed consolidated balance sheets. Historically, borrowers who elected to prepay term loans were required to pay future interest and fees that would have been assessed had the term loan been repaid in accordance with its original agreement. Beginning in December 2014, certain term loans may be eligible for a discount of future interest and fees that would have been assessed had the loan been repaid in accordance with its original agreement. Gain on Sales of Loans In October 2013, we started OnDeck Marketplace whereby we originate and sell certain loans to third-party purchasers and retain servicing rights. We account for the loan sales in accordance with ASC Topic 860, Transfers and Servicing, which states that a transfer of a financial asset, a group of financial assets, or a participating interest in a financial asset is accounted for as a sale if all of the following conditions are met: 1. The financial assets are isolated from the transferor and its consolidated affiliates as well as its creditors. 2. The transferee or beneficial interest holders have the right to pledge or exchange the transferred financial assets. 3. The transferor does not maintain effective control of the transferred assets. For the nine months ended September 30, 2015 and 2014 , all sales met the requirements for sale treatment in accordance with ASC Topic 860, Transfers and Servicing . We record the gain or loss on the sale of a loan at the sale date in an amount equal to the proceeds received, adjusted for initial recognition of servicing assets or liabilities obtained at the date of sale, less outstanding principal and net deferred origination costs. Other Revenue Other revenue includes servicing revenue related to loans previously sold, fair value adjustments to servicing rights, marketing fees earned from our issuing bank partner, which are recognized as the related services are provided, and monthly fees charged to customers for our line of credit products. Stock-Based Compensation In accordance with ASC Topic 718, Compensation—Stock Compensation , all stock-based compensation provided to employees is measured based on the grant-date fair value of the awards and recognized as compensation expense on a straight-line basis over the period during which the award holder is required to perform services in exchange for the award (the vesting period). We issue stock options to employees and directors, which are valued using the Black-Scholes-Merton Option Pricing Model to estimate the fair value of stock options. The use of the option valuation model requires subjective assumptions, including the fair value of our common stock, the expected term of the option and the expected stock price volatility, which is based on our stock as well as our peer companies. We issue restricted stock units ("RSUs") to employees and directors, which are measured based on the fair values of the underlying stock on the dates of grant. Additionally, the recognition of stock-based compensation expense requires an estimation of the number of options and RSUs that will ultimately vest and the number of options and RSUs that will ultimately be forfeited. Estimated forfeitures are subsequently adjusted to reflect actual forfeiture. Recent Accounting Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU 2014-09, Revenue Recognition , which creates ASC 606, Revenue from Contracts with Customers , and supersedes ASC 605, Revenue Recognition . ASU 2014-09 requires revenue to be recognized in an amount that reflects the consideration to which the entity expects to be entitled in exchange for goods or services as described in ASU 2014-09. In July 2015, the FASB voted to defer the effective date of the new revenue standard by one year. The new guidance will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted, but not before the original effective date of December 15, 2016. We are currently in the process of assessing the impact the adoption of this guidance will have on our consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs , which amends ASC 835-30, Interest - Imputation of Interest. ASU 2015-03 requires entities to change the presentation of debt issuance costs in the financial statements. Under the ASU, an entity will be required to present such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. This accounting standard is effective beginning January 1, 2016. We are currently assessing the impact this accounting standard will have on our consolidated financial statements.

The facility bears interest at LIBOR plus 3.00% , and matures in May 2017. On May 22, 2015 an amendment was made to the ODAC Agreement extending the date of maturity from October 2016 to May 2017. In addition to other changes, this facility is now exclusively for the use of financing our line of credit product. On June 12, 2015, through a wholly-owned bankruptcy remote subsidiary, we entered into a $100 million revolving line of credit with Bank of America, N.A. ("PORT Agreement"). The facility bears interest at LIBOR plus 2.25% , and matures in June 2017. On August 13, 2015, an amendment was made to the ODAP Agreement converting the Lenders’ obligation from a commitment to make revolving loans to ODAP of up to $75 million to an agreement under which the Lenders are allowed to make, on an uncommitted basis, revolving loans to ODAP of up to $100 million ; extending the revolving termination date (i.e., the period during which ODAP is permitted to request the advance of revolving loans) by approximately one year to August 13, 2016 and the amortization period end date by approximately one year to August 13, 2017; increasing the borrowing advance rate; and various other changes. On October 2, 2015 an amendment was made to the Square 1 Agreement which extended the date of maturity from October 2015 to October 2016, added a minimum monthly interest payment and modified certain financial and portfolio covenants. On October 7, 2015 an amendment was made to the ODART Agreement extending the date of maturity from September 2016 to September 2017. As a result of the amendment, the Class A revolving loans will bear interest at a rate of Cost of Funds plus 2.25% and, at ODART's request, the Class B revolving lending commitment was terminated, reducing the total facility to $150 million . At ODART’s election, the $17.6 million Class B revolving commitment can be reintroduced which would restore the facility to $167.6 million . The borrowing base will be 95% and the interest rate will be LIBOR plus 7.00% for such Class B revolving loans. The amendment will further allow for a specified portion of the financing for weekly paying term loans.

Income Tax

Income Tax Disclosure [Abstract]
Income Tax	Income Tax As part of the process of preparing the unaudited condensed consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves determining the annual effective tax rate, income tax expense (benefit) and deferred income tax expense (benefit) related to temporary differences resulting from differing treatment of items, such as the loan loss reserve, timing of depreciation and deferred rent liabilities, for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within the accompanying unaudited condensed consolidated balance sheets. We must then assess the likelihood that the deferred tax assets will be recovered through the generation of future taxable income. We have not incurred any income tax during the three and nine months ended September 30, 2015 and 2014 due to one or more of the following reasons: • the book losses incurred during those periods; • the anticipated and known book losses for years ending December 31, 2015 and ended 2014 , respectively, or; • the significant deferred tax assets available for application should permanent and temporary differences from book income yield taxable income. We claimed deductions on our U.S. federal tax return for certain expenses related to our initial public offering that were validated at the level of substantial authority, but did not exceed the "more likely than not" threshold. Deductions that are not deemed more likely than not to withstand examination by a taxing authority are considered to be "uncertain tax positions" as defined in ASC 740 Income Taxes . We estimate the tax-effected exposure of these deductions to be approximately $2.2 million . These deductions did not result in any change to our tax payable or our provision for income taxes, both of which were $0 as of and for the nine months ended September 30, 2015, as we would have been in a loss position for both book and tax purposes without regard to these deductions. These deductions will increase our deferred tax asset as well as the corresponding valuation allowance. There will be no financial statement benefit derived from this additional deferred tax asset until such time as the valuation allowance is released. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. Based upon the level of historical losses and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that we will not realize the benefits of these deductible differences in the foreseeable future. Therefore, we have recorded a full valuation allowance against our net deferred tax asset.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Assets and Liabilities Measured at Fair Value on a Recurring Basis Using Significant Unobservable Inputs (Level 3) We evaluate our financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level at which to classify them for each reporting period. Due to the lack of transparency and quantity of transactions related to trades of servicing rights of comparable loans, we utilize an income valuation technique to estimate fair value. We utilize industry-standard modeling, such as discounted cash flow models, to arrive at an estimate of fair value and may utilize independent service providers to assist in the valuation process. This determination requires significant judgment. The following tables present information about our assets and liabilities that are measured at fair value on a recurring basis as of September 30, 2015 (in thousands): September 30, 2015 Description Level 1 Level 2 Level 3 Total Assets: Servicing assets $ — $ — $ 2,252 $ 2,252 Total assets $ — $ — $ 2,252 $ 2,252 There were no transfers between levels during the nine months ended September 30, 2015 . The following tables presents quantitative information about the significant unobservable inputs used for certain of our Level 3 fair value measurement at September 30, 2015 . Servicing Rights September 30, 2015 Unobservable input Weighted Average Servicing assets Discount rate 30.00 % Cost of service (1) 0.07 % Renewal rate 43.44 % Default rate 6.43 % (1) Estimated cost of servicing a loan as a percentage of unpaid principal balance. The weighted averages above are indicative of the range for discount rate, cost of service and default rate. The renewal rate had a range of 35.44% to 50.91% during the three months ended September 30, 2015 . The above unobservable inputs were consistent during the three months ended September 30, 2015 when servicing right assets were initially recognized. Changes in certain of the unobservable inputs noted above may have a significant impact on the fair value of our servicing asset. The following table summarizes the effect adverse changes in estimate would have on the value of the servicing asset that we carry at fair value as of September 30, 2015 given a hypothetical changes in default rate and cost to service (in thousands): Servicing Assets Default rate assumption: Default rate increase of 25% (92 ) Default rate increase of 50% (182 ) Cost to service assumption: Cost to service increase by 25% (53 ) Cost to service increase by 50% (106 ) We had no servicing assets or liabilities as of December 31, 2014. Warrant Liability The following table presents the changes in the Level 3 instruments measured at fair value on a recurring basis for the three and nine months ended September 30, 2014 (in thousands): Three Months Ended September 30, 2014 Nine Months Ended September 30, 2014 Warrant liability balance - beginning of period $ 13,272 $ 4,446 Exercise of warrants (10,770 ) (10,766 ) Change in fair value 300 9,122 Warrant liability balance - end of period $ 2,802 $ 2,802 The warrant liability is classified within Level 3 due to the liability being valued using significant unobservable inputs. Fair value of these warrants is based on a valuation of our common stock. As the valuation of our common stock was determined prior to our initial public offering, we used a combination of the inputs including option pricing models, secondary transactions with third-party investors and an initial public offering scenario to determine the valuation of our common stock. A hypothetical increase or decrease in assumed asset volatility of 10% in the option pricing model would result in an immaterial impact to the fair value of the warrants as of September 30, 2014 . In the unaudited consolidated statements of operations, changes in fair value are included in warrant liability fair value adjustment. Assets and Liabilities Disclosed at Fair Value As loans are not measured at fair value, the following discussion relates to estimating the fair value disclosure under ASC Topic 825. The fair value of loans is estimated by discounting scheduled cash flows through the estimated maturity. The estimated market discount rates used for loans are our current offering rates for comparable loans with similar terms. The carrying amounts of certain of our financial instruments, including loans and loans held for sale, approximate fair value due to their short-term nature and are considered Level 3. The carrying amount of our financing obligations, such as fixed-rate debt, approximates fair value, by considering the borrowing rates currently available to us for financing obligations with similar terms and credit risks.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments In March 2015, we amended the lease of our New York City corporate headquarters to extend the lease and rent additional space. We will occupy the additional space incrementally, as it becomes available, at which time we will incur a proportionate amount of additional rent payments. The dates the additional space will be available are uncertain as they are dependent upon the departure of current occupants and the landlord’s ability to prepare the space. Upon the completion of delivery of all additional space, our additional average monthly fixed rent payment will be approximately $0.4 million . The amended lease also provides for rent credits aggregating $3.6 million and a tenant improvement allowance not to exceed $5.8 million . The lease will terminate ten years and ten months after the delivery of certain portions of the additional space. In April 2015, we provided notice of termination to the landlord of our current office space in Denver, Colorado resulting in a termination fee of $0.4 million which is included in general and administrative expense for the nine months ended September 30, 2015. The lease is scheduled to expire in January 2016. In June 2015, we entered into a sublease in Denver, Colorado (the "New Denver Lease") as the subtenant. The New Denver Lease is for approximately 72,000 square feet with an average monthly fixed rent payment of approximately $144,000 . The New Denver Lease also provides for a tenant improvement allowance not to exceed $2.6 million . The lease has a term of 124 months after the commencement date. Concentrations of Credit Risk Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash, cash equivalents, restricted cash and loans. We hold cash, cash equivalents and restricted cash in accounts at regulated domestic financial institutions in amounts that may exceed FDIC insured amounts and at non-U.S. financial institutions where deposited amounts may be uninsured. We believe these institutions to be of acceptable credit quality and we have not experienced any related losses to date. We are exposed to default risk on loans we originate and hold and that we purchase from our issuing bank partner. We perform an evaluation of each customer's financial condition and during the term of the customer's loan(s), we have the contractual right to limit a customer's ability to take working capital loans or other financing from other lenders that may cause a material adverse change in the financial condition of the customer. There is no single customer or group of customers that comprise a significant portion of our loan portfolio. Contingencies Two separate putative class actions were filed in August 2015 in the United States District Court for the Southern District of New York against us, certain of our executive officers, our directors and certain or all of the underwriters of our initial public offering, or IPO. The suits allege that the registration statement for our IPO contained materially false and misleading statements regarding, or failed to disclose, specified information in violation of the Securities Act of 1933, as amended. The suits seek a determination that the case is a proper class action and/or certification of the plaintiff as a class representative, rescission or a rescissory measure of damages and/or unspecified damages, interest, attorneys’ fees and other fees and costs.The deadline for seeking lead plaintiff status was October 5, 2015. The court has not ruled on the pending motion for consolidation of the two suits into a single case, the appointment of a lead plaintiff and approval of plaintiff’s counsel. The Company intends to defend itself vigorously in these matters, although at this time we cannot predict the outcome. From time to time we are subject to other legal proceedings and claims in the ordinary course of business. The results of such matters cannot be predicted with certainty. However, we believe that the final outcome of any such current matters will not result in a material adverse effect on our consolidated financial condition, consolidated results of operations or consolidated cash flows.

All intercompany transactions and accounts have been eliminated in consolidation. The results of operations for the three and nine months ended September 30, 2015 are not necessarily indicative of the results for the full year or the results for any future periods. We have reclassified certain prior-period amounts to conform to the current period’s presentation. These unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements, including the related notes, and the other information contained in our Annual Report on Form 10-K for the year ended December 31, 2014 . When used in these notes to condensed consolidated financial statements, the terms "we," "us," "our" or similar terms refers to On Deck Capital, Inc. and its consolidated subsidiaries.
Use of Estimates	The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts in the condensed consolidated financial statements and accompanying notes. Significant estimates include allowance for loan losses, valuation of warrants, stock-based compensation expense, servicing assets/liabilities, capitalized software development costs, the useful lives of long-lived assets and valuation allowance for deferred tax assets. We base our estimates on historical experience, current events and other factors we believe to be reasonable under the circumstances. These estimates and assumptions are inherently subjective in nature; actual results may differ from these estimates and assumptions.
Loans and Loans Held for Sale	Loans We originate term loans and lines of credit (collectively, “loans”) that are generally short term in nature and require daily or weekly repayments. We have both the ability and intent to hold these loans to maturity. When we originate a term loan, the borrower grants us a security interest in its assets. We may or may not perfect our security interest by publicly filing a financing statement. Loans are carried at amortized cost, reduced by a valuation allowance for loan losses estimated as of the balance sheet dates. In accordance with ASC Subtopic 310-20, Nonrefundable Fees and Other Costs , the amortized cost of a loan is equal to the unpaid principal balance, plus net deferred origination costs. Net deferred origination costs are comprised of certain direct origination costs, net of all loan origination fees received. Loan origination fees include fees charged to the borrower related to origination that increase the loan’s effective interest yield. Direct origination costs in excess of loan origination fees received are included in the loan balance and amortized over the term of the loan using the effective interest method. Loan origination costs are limited to direct costs attributable to originating a loan, including commissions and personnel costs directly related to the time spent by those individuals performing activities related to loan origination. Additionally, when a term loan is originated in conjunction with the extinguishment of a previously issued term loan, also known as a renewal, we determine whether this is a new loan or a modification to an existing loan in accordance with ASC 310-20. If accounted for as a new loan, any remaining unamortized net deferred costs are recognized when the new loan is originated. Further, when a renewal is accounted for as a new loan, the cash flows of the origination and related net deferred origination costs of that new loan are presented as operating cash outflows on the Statement of Cash Flows if the renewal is designated to be sold or as investing cash outflows if the renewal is designated to be held for investment. If a renewal is accounted for as a modification, any remaining unamortized net deferred costs are amortized over the life of the modified loan. Further, when a renewal is accounted for as a modification, the additional cash flows associated with the origination and related net deferred origination costs of that modification are presented on the Statement of Cash Flows within the same section as the originally issued term loan prior to renewal. Loans Held for Sale OnDeck Marketplace ® is a program whereby we originate and sell certain term loans to third-party institutional investors and retain servicing rights. We sell these whole loans to purchasers in exchange for a cash payment. A portion of our loans are originated for the purpose of being sold through OnDeck Marketplace . These whole loans are initially classified as held for sale within a short period of time from the initial funding when the whole loan is identified for sale and a plan exists for the sale. A loan that is initially designated as held for sale or held for investment may be reclassified when our intent for that loan changes. When a loan held for sale is reclassified to held for investment, the loan is recorded at amortized costs and an appropriate provision for loan loss is recorded. When a loan held for investment is reclassified to held for sale, any allowance for loan loss related to that loan will be released. Loans held for sale, inclusive of net deferred origination costs, are recorded at the lower of amortized cost or fair value until the loans are sold or reclassified. Servicing Rights We service loans that we have sold to third parties and upon such sale, we may recognize a servicing asset or liability, collectively referred to as servicing rights. Receiving more than adequate compensation, as defined by ASC Topic 860 Transfers and Servicing , results in the recognition of a servicing asset. Receiving less than adequate compensation results in a servicing liability. Servicing assets and liabilities are recorded at fair value and are presented as a component of other assets or accrued expenses and other liabilities, respectively. The initial recognition of a servicing asset results in a corresponding increase to gain on sales of loans. The initial recognition of a servicing liability results in a corresponding decrease to gain on sales of loans. Subsequent adjustments to the fair value of servicing rights are recognized as an adjustment to other revenue. We utilize industry-standard modeling, such as discounted cash flow models, to arrive at an estimate of fair value and may utilize independent service providers to assist in the valuation process. Significant assumptions used in valuing our servicing rights are as follows: • Adequate compensation: We estimate adequate compensation as the rate a willing market participant would require to service loans with similar characteristics as those in the serviced portfolio. In the event of a lack of transparency and quantity of transactions related to trades of servicing rights of comparable loans (i.e., loans with comparable terms, unpaid principal balances, renewal rates and default rates) we may consider the actual cost incurred as an appropriate proxy for what a market participant would require to service the loans. • Discount rate: For servicing rights on loans, the discount rate reflects the time value of money and a risk premium intended to reflect the amount of compensation market participants would require. • Renewal rate: We estimate the timing and probability that a borrower may renew their loan in advance of scheduled repayment, thus reducing the projected unpaid principal balance and expected term of the loan, which are used to project future servicing revenues. • Default rate: We estimate the timing and probability of loan defaults and write-offs, thus reducing the projected unpaid principal balance and expected term of the loan, which are used to project future servicing revenues. Allowance for Loan Losses The allowance for loan losses (“ALLL”) is established through periodic charges to the provision for loan losses. Loan losses are charged against the ALLL when we believe that the future collection of principal is unlikely. Subsequent recoveries, if any, are credited to the ALLL. We evaluate the creditworthiness of our portfolio on a pooled basis due to its composition of small, homogeneous loans with similar general credit risk characteristics and diversification among variables including industry and geography. We use a proprietary forecast loss rate at origination for new loans that have not had the opportunity to make payments when they are first funded. The forecasted loss rate is updated daily to reflect actual loan performance, and the underlying ALLL model is updated monthly to reflect our assumptions. The allowance is subjective as it requires material estimates, including such factors as historical trends, known and inherent risks in the loan portfolio, adverse situations that may affect borrowers’ ability to repay and current economic conditions. Other qualitative factors considered may include items such as uncertainties in forecasting and modeling techniques, changes in portfolio composition, seasonality, business conditions and emerging trends. Recovery of the carrying value of loans is dependent to a great extent on conditions that may be beyond our control. Any combination of the aforementioned factors may adversely affect our loan portfolio resulting in increased delinquencies and loan losses and could require additional provisions for credit losses, which could impact future periods. In our opinion, we have provided adequate allowances to absorb probable credit losses inherent in our loan portfolio based on available and relevant information affecting the loan portfolio at each balance sheet date. Accrual for Unfunded Loan Commitments and Off-Balance Sheet Credit Exposures For our line of credit product we estimate probable losses on unfunded loan commitments similarly to the ALLL process and include the calculated amount in accrued expenses and other liabilities. We believe the accrual for unfunded loan commitments is sufficient to absorb estimated probable losses related to these unfunded credit commitments. The determination of the adequacy of the accrual is based on evaluations of the unfunded credit commitments, including an assessment of the probability of commitment usage, credit risk factors for lines of credit outstanding to these customers and the terms and expiration dates of the unfunded credit commitments. As of September 30, 2015 and December 31, 2014 , our off-balance sheet credit exposure related to the undrawn line of credit balances was $65.1 million and $28.7 million , respectively. The related accrual for unfunded loan commitments was $3.2 million and $1.3 million as of September 30, 2015 and December 31, 2014 , respectively. Net adjustments to the accrual for unfunded loan commitments are included in general and administrative expenses. Accrual for Third-Party Representations We have made certain representations to third parties that purchase loans through OnDeck Marketplace . There are no restricted assets related to the underlying loan sale agreements. Any significant estimated post-sale obligations or contingent obligations to the purchaser of the loans, such as fraudulent loan repurchase obligations or excess loss indemnification obligations, would be accrued if probable and estimable in accordance with ASC 450, Contingencies .
Revenue Recognition	Interest Income We generate revenue primarily through interest and origination fees earned on loans originated and held to maturity. We recognize interest and origination fee revenue over the terms of the underlying loans using the effective interest method. Origination fees collected but not yet recognized as revenue are netted with direct origination costs and presented as a component of loans in our condensed consolidated balance sheets. Historically, borrowers who elected to prepay term loans were required to pay future interest and fees that would have been assessed had the term loan been repaid in accordance with its original agreement. Beginning in December 2014, certain term loans may be eligible for a discount of future interest and fees that would have been assessed had the loan been repaid in accordance with its original agreement. Gain on Sales of Loans In October 2013, we started OnDeck Marketplace whereby we originate and sell certain loans to third-party purchasers and retain servicing rights. We account for the loan sales in accordance with ASC Topic 860, Transfers and Servicing, which states that a transfer of a financial asset, a group of financial assets, or a participating interest in a financial asset is accounted for as a sale if all of the following conditions are met: 1. The financial assets are isolated from the transferor and its consolidated affiliates as well as its creditors. 2. The transferee or beneficial interest holders have the right to pledge or exchange the transferred financial assets. 3. The transferor does not maintain effective control of the transferred assets. For the nine months ended September 30, 2015 and 2014 , all sales met the requirements for sale treatment in accordance with ASC Topic 860, Transfers and Servicing . We record the gain or loss on the sale of a loan at the sale date in an amount equal to the proceeds received, adjusted for initial recognition of servicing assets or liabilities obtained at the date of sale, less outstanding principal and net deferred origination costs. Other Revenue Other revenue includes servicing revenue related to loans previously sold, fair value adjustments to servicing rights, marketing fees earned from our issuing bank partner, which are recognized as the related services are provided, and monthly fees charged to customers for our line of credit products.
Stock-Based Compensation	In accordance with ASC Topic 718, Compensation—Stock Compensation , all stock-based compensation provided to employees is measured based on the grant-date fair value of the awards and recognized as compensation expense on a straight-line basis over the period during which the award holder is required to perform services in exchange for the award (the vesting period). We issue stock options to employees and directors, which are valued using the Black-Scholes-Merton Option Pricing Model to estimate the fair value of stock options. The use of the option valuation model requires subjective assumptions, including the fair value of our common stock, the expected term of the option and the expected stock price volatility, which is based on our stock as well as our peer companies. We issue restricted stock units ("RSUs") to employees and directors, which are measured based on the fair values of the underlying stock on the dates of grant. Additionally, the recognition of stock-based compensation expense requires an estimation of the number of options and RSUs that will ultimately vest and the number of options and RSUs that will ultimately be forfeited. Estimated forfeitures are subsequently adjusted to reflect actual forfeiture.
Recent Accounting Pronouncements Not Yet Adopted	In May 2014, the FASB issued ASU 2014-09, Revenue Recognition , which creates ASC 606, Revenue from Contracts with Customers , and supersedes ASC 605, Revenue Recognition . ASU 2014-09 requires revenue to be recognized in an amount that reflects the consideration to which the entity expects to be entitled in exchange for goods or services as described in ASU 2014-09. In July 2015, the FASB voted to defer the effective date of the new revenue standard by one year. The new guidance will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted, but not before the original effective date of December 15, 2016. We are currently in the process of assessing the impact the adoption of this guidance will have on our consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs , which amends ASC 835-30, Interest - Imputation of Interest. ASU 2015-03 requires entities to change the presentation of debt issuance costs in the financial statements. Under the ASU, an entity will be required to present such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. This accounting standard is effective beginning January 1, 2016. We are currently assessing the impact this accounting standard will have on our consolidated financial statements.
Fair Value Measurements	We evaluate our financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level at which to classify them for each reporting period. Due to the lack of transparency and quantity of transactions related to trades of servicing rights of comparable loans, we utilize an income valuation technique to estimate fair value. We utilize industry-standard modeling, such as discounted cash flow models, to arrive at an estimate of fair value and may utilize independent service providers to assist in the valuation process. This determination requires significant judgment. As loans are not measured at fair value, the following discussion relates to estimating the fair value disclosure under ASC Topic 825. The fair value of loans is estimated by discounting scheduled cash flows through the estimated maturity. The estimated market discount rates used for loans are our current offering rates for comparable loans with similar terms. The carrying amounts of certain of our financial instruments, including loans and loans held for sale, approximate fair value due to their short-term nature and are considered Level 3. The carrying amount of our financing obligations, such as fixed-rate debt, approximates fair value, by considering the borrowing rates currently available to us for financing obligations with similar terms and credit risks.
