Basis of Presentation and Significant Accounting Policies	3 Months Ended

Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014, which was filed with the SEC on March 2, 2015 (“2014 Form 10-K”).
	The condensed consolidated balance sheet as of December 31, 2014, included herein, was derived from the audited financial statements as of that date but does not include all disclosures, including notes required by U.S. GAAP.
	In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial positions, results of operations and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2015 or any future period.
	Principles of Consolidation
	The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.
	Use of Estimates
	The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to 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 period. Management evaluates estimates on a regular basis including those relating to revenue recognition, the allowance for doubtful accounts, goodwill, intangible assets, the valuation of deferred income taxes, stock-based compensation and unrecognized tax benefits, among others. Actual results could differ from those estimates and such differences may have a material impact on the Company’s condensed consolidated financial statements and footnotes.
	Significant Accounting Policies
	The Company’s significant accounting policies are described in Note 2 of the Notes to Consolidated Financial Statements in its 2014 Form 10-K. There have been no significant changes to these policies.
	Other Income, Net
	Other income, net consisted of the following:
		Three Months ended March 31,
		2015			2014
		(in thousands)
	Interest income	$	159		$	122
	Net realized gain on investments	—			1
	Interest expense	(27		)	(23		)
	Total other income, net	$	132		$	100
	Comprehensive Income
	Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes certain changes in equity that are excluded from net income, specifically unrealized gains (losses) on available-for-sale investments. Except for net realized gain on investments which was not significant, there were no reclassifications out of accumulated other comprehensive income (loss) that affected net income during the three months ended March 31, 2015 and 2014.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 also requires significantly expanded disclosures about revenue recognition. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. On April 29, 2015, the FASB issued a proposed ASU to defer the effective date of ASU 2014-09. Under the proposal, ASU 2014-09 will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, but entities will be permitted to early adopt the standard as of the original effective date. The Company has not yet developed an expectation of the impact that adoption will have on its consolidated financial statements.
	In April 2015, the FASB issued ASU No. 2015-05, Intangibles—Goodwill and Other—Internal-Use Software (“ASU 2015-05”), which clarifies the circumstances under which a cloud computing customer would account for the arrangement as a license of internal-use software. ASU 2015-05 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. The Company has not yet developed an expectation of the impact that adoption will have on its consolidated financial statements.

Net Income (Loss) Per Share of Common Stock	3 Months Ended
	Mar. 31, 2015
Earnings Per Share [Abstract]
Net Income (Loss) Per Share of Common Stock	Net income per share of common stock is calculated by dividing net income by the weighted average shares of common stock outstanding during the period. Diluted net income per share of common stock is calculated by dividing net income by the weighted average shares of common stock outstanding and potential shares of common stock during the period. Potential shares of common stock include dilutive shares attributable to the assumed exercise of stock options, restricted stock unit awards (“RSUs”), performance-vesting RSUs, performance share awards (“Performance Awards”) and Employee Stock Purchase Plan (“ESPP”) shares using the treasury stock method, if dilutive.
	The components of net income per share of common stock were as follows:
		Three Months ended March 31,
		2015			2014
		(in thousands, except share and per share amounts)
	Net income	$	3,584		$	782
	Basic shares:
	Weighted average common shares outstanding	28,768,144			27,339,394
	Diluted shares:
	Weighted average shares used to compute basic net income per share	28,768,144			27,339,394
	Effect of potentially dilutive securities:
	Employee stock options, RSUs, performance-vesting RSUs, Performance Awards and ESPP shares	1,674,019			1,730,736
	Weighted average shares used to compute diluted net income per share	30,442,163			29,070,130
	Net income per share:
	Basic	$	0.12		$	0.03
	Diluted	$	0.12		$	0.03
	The following potential common shares were excluded from the computation of diluted net income per share, as their effect would have been anti-dilutive:
		Three Months ended March 31,
		2015		2014
	Employee stock options and awards	346,256		910,812
	Performance-vesting RSUs and Performance Awards are included in the diluted shares outstanding for each period if the established performance criteria have been met at the end of the respective periods. However, if none of the required performance criteria have been met for such awards, the Company includes the number of shares that would be issuable if the end of the reporting period were the end of the contingency period. Accordingly, in addition to the employee stock options and awards noted above, 157,491 and 90,625 shares underlying performance-vesting RSUs and Performance Awards were excluded from the dilutive shares outstanding for each of the three months ended March 31, 2015 and 2014, respectively.

Financial Instruments and Fair Value Measurements [Abstract]
Financial Instruments and Fair Value Measurements	Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are classified and disclosed in one of the following three categories:
	Level 1 — Valuations based on quoted prices in active markets for identical assets or liabilities.
	Level 2 — Valuations based on other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3 — Valuations based on inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the assets or liabilities.
	The following tables set forth by level within the fair value hierarchy the Company’s financial assets that were accounted for at fair value on a recurring basis, according to the valuation techniques the Company used to determine their values:
		Fair value at		Fair value measurements
				using inputs considered as
		March 31, 2015		Level 1			Level 2			Level 3
		(in thousands)
	Money market funds	$	3,119	$	3,119		$	—		$	—

		$	111,251	$	20,166		$	91,085		$	—
	Financial instruments include cash, cash equivalents and investments including investment-grade interest-bearing securities, such as money market accounts, certificates of deposit, commercial paper, corporate bonds, municipal and government agency obligations and guaranteed obligations of the U.S. government. The Company classifies its money market funds that are specifically backed by debt securities and U.S. government obligations as Level 1 instruments due to the use of observable market prices for identical securities that are traded in active markets.
	When the Company uses observable market prices for identical securities that are traded in less active markets, the Company classifies its marketable financial instruments as Level 2. When observable market prices for identical securities are not available, the Company prices its marketable financial instruments using non-binding market consensus prices that are corroborated with observable market data; quoted market prices for similar instruments; or pricing models with all significant inputs derived from or corroborated with observable market data. Non-binding market consensus prices are based on the proprietary valuation models of pricing providers. These valuation models incorporate a number of inputs, including non-binding and binding broker quotes; observable market prices for identical or similar securities; and the internal assumptions of pricing providers or brokers that use observable market inputs and, to a lesser degree, unobservable market inputs. The Company corroborates non-binding market consensus prices with observable market data as such data exists.
	At March 31, 2015 and December 31, 2014, the Company did not have any assets or liabilities that were valued using Level 3 inputs. For the three months ended March 31, 2015 and 2014, there were no transfers of financial instruments among Level 1, Level 2 or Level 3 classifications.
	For the three months ended March 31, 2015 and 2014 the Company recognized interest income from financial instruments of $0.2 million and $0.1 million, respectively. Gross realized gains and gross realized losses from the sale of investments were not significant during the three months ended March 31, 2015 and 2014.
	The carrying amounts, gross unrealized gains and losses and estimated fair value of cash and cash equivalents and both short-term and long-term investments consisted of the following:

Income_Taxes

Income Taxes	3 Months Ended
	Mar. 31, 2015
Income Tax Disclosure [Abstract]
Income Taxes	The Company computes its interim provision for income taxes by applying the estimated annual effective tax rate to the year-to-date income from recurring operations and adjust the provision for discrete tax items recorded in the period. The Company evaluates and updates its estimated annual effective income tax rate on a quarterly basis. The estimated annual effective tax rate as of March 31, 2015 and 2014 was 45.8% and 26.0%, respectively.
	The difference between the federal statutory rate of 35% and the Company’s estimated effective tax rate for the three months ended March 31, 2015 was primarily due to the Company’s state income tax provision and non-deductible stock-based compensation expenses, offset by the domestic production activities deduction under Internal Revenue Code (“IRC”) Section 199. The Company’s annual estimated effective tax rate fluctuates quarterly due to the impact of stock based compensation deductions on the IRC Section 199 deduction.
	The Company accounts for stock-based compensation pursuant to ASC 718 and uses ASC 740 ordering when determining when excess tax benefits have been realized. The Company realized a tax benefit of $2.9 million for the three months ended March 31, 2015 related to the exercise of employee stock options and the vesting of RSUs, performance-vesting RSUs and Performance Awards. The net income tax benefit in excess of the expenses recorded for financial reporting purposes has been recorded as an increase to additional paid-in capital and is reflected as a financing cash inflow in the condensed consolidated statements of cash flows.
	The Company’s tax positions are subject to income tax audits by multiple tax jurisdictions. The Company accounts for uncertain tax positions and believes that it has provided adequate reserves for its unrecognized tax benefits for all tax years still open for assessment. The Company also believes that it does not have any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease within the next twelve months.
	The Company has a policy to classify accrued interest and penalties associated with uncertain tax positions together with the related liability in the balance sheet, and to include the expenses incurred related to such accruals in the provision for income taxes. There were no interest or penalties included in the provision for income taxes during the three months ended March 31, 2015 and 2014, respectively.

Commitments and Contingencies	Leases
	The Company leases certain fixed assets under non-cancelable capital leases with various expiration dates. In January 2015, the Company entered into a lease agreement to finance the purchase of computer equipment for the Company’s data centers with payments of $0.3 million per month over the 24 month term of the agreement. In January 2015, the Company entered into an amendment to the Company’s existing lease of office space in Irvine, California, in which the Company will make payments of $8,800 per month over the 12 month term of the lease agreement.
	Legal Proceedings
	From time to time, the Company is involved in litigation that it believes is of the type common to companies engaged in the Company’s line of business, including commercial disputes and employment issues. As of the date of this Quarterly Report on Form 10-Q, the Company is not involved in any pending legal proceedings whose outcome the Company expects to have a material adverse effect on its financial position, results of operations or cash flows. However, litigation is unpredictable and excessive verdicts, both in the form of monetary damages and injunctions, could occur. In the future, litigation could result in substantial costs and diversion of resources and the Company could incur judgments or enter into settlements of claims that could have a material adverse effect on its business.

	Intrinsic value of an option is the difference between the fair value of the Company’s common stock at the time of exercise and the exercise price to be paid. The aggregate intrinsic value for options outstanding at March 31, 2015 in the table above represents the total intrinsic value, based on the Company’s closing stock price of $55.31 as of March 31, 2015, which would have been received by option holders had all option holders exercised their in-the-money options as of that date. Options outstanding that are expected to vest are net of estimated future option forfeitures.
	Following is additional information pertaining to the Company’s stock option activity:
		Three Months ended March 31,

	As of March 31, 2015, total unrecognized stock-based compensation expense related to unvested stock options, adjusted for estimated forfeitures, was $16.9 million and is expected to be recognized over a weighted average period of 2.6 years.
	Restricted Stock Units, Performance-Vesting Restricted Stock Units and Performance Awards
	The Performance Awards granted represent the right to receive shares of the Company’s common stock, contingent upon the achievement of certain of the Company’s performance metrics during the performance period. Subsequent to the performance period, the Compensation Committee of the Board of Directors (the “Compensation Committee”) determines and approves the achievement of the performance goals (the “Determination Date”) and the earned shares are issued, with 25% of the shares vested upon issuance and the remaining shares to vest 25% on each of the first three anniversaries of the Determination Date, subject to the continuous employment of the participant through such dates.
	In August 2012, the Company granted 147,000 Performance Awards with a performance period of July 1, 2012 through June 30, 2013. On the Determination Date in August 2013, the Compensation Committee determined that 588,000 shares of common stock had been earned.
	In February 2013, the Company granted 113,000 Performance Awards with a performance period of January 1, 2013 through December 31, 2013. On the Determination Date in March 2014, the Compensation Committee determined that 124,300 shares of common stock had been earned.
	In February 2014, the Company granted 62,500 Performance Awards with a performance period of January 1, 2014 through December 31, 2014. On the Determination Date in March 2015, the Compensation Committee determined that 107,350 shares of common stock had been earned.
	In February 2015 and March 2015, the Company granted 24,766 and 10,324 Performance Awards with a performance period of January 1, 2015 through December 31, 2015. The designated participants may earn between zero and 2.0 shares of common stock for each award. As of March 31, 2015, the Company expects that each award will convert to 1.3 shares of common stock on the Determination Date.
	In December 2014, the Company granted Sigmund Anderman, then Chief Executive Officer and current Chairman of the Board of Directors of the Company, an option to purchase 76,648 shares of Company common stock and 37,203 performance-vesting RSUs. In January 2015, the Company granted Mr. Anderman an option to purchase 71,648 shares of Company common stock and 34,714 performance-vesting RSUs. The options will have a four-year, employment-based vesting schedule with 25% of the total number of options to vest on the first anniversary of the grant date and 1/48th of the total number of options to vest monthly thereafter. The performance-vesting RSUs will vest based upon the achievement of the corporate goals for fiscal year 2015 and continued employment. On the date the board of directors or the compensation committee certifies the achievement of the Company’s corporate goals for fiscal year 2015 (the “2015 RSU Determination Date”), Mr. Anderman may earn up to 2.0 shares of common stock for each of the performance-vesting RSUs. 25% of the total number of performance-vesting RSUs will vest and be issued on the 2015 RSU Determination Date, and the remaining shares will vest and be issued 25% on each of December 31, 2016, 2017 and 2018, subject to the continuous employment of Mr. Anderman through such dates. As of March 31, 2015, the Company expects that each of the performance-vesting RSUs will convert to 1.6 shares of common stock on the 2015 RSU Determination Date.

Segment Reporting [Abstract]
Segment Information	The Company operates in one industry—mortgage-related software and services. The Company’s chief operating decision maker is its chief executive officer, who makes decisions about resource allocation and reviews financial information presented on a consolidated basis. Accordingly, the Company has determined that it has a single reporting segment and operating unit structure, specifically technology-enabled solutions to help streamline and automate the residential mortgage origination process for its network participants.
	The Company is organized primarily on the basis of service lines. Supplemental disclosure of revenues by type is as follows:

	On-premise revenues	1,517		2,032
		$	54,189	$	32,178
	On-demand revenue is generated from company-hosted software subscriptions that customers access through the Internet and from customers that pay fees based on a per closed loan, or success, basis subject to monthly base fees, which we refer to as Success-Based Pricing. Additionally, on-demand revenue is comprised of software services sold transactionally; Ellie Mae Network transaction fees; education and training, loan product and guideline data and analytics services under the AllRegs brand; and professional services which include consulting, implementation and training services.
	On-premise revenue is generated from maintenance services, sales of customer-hosted software licenses, and related professional services.

Accounting Policies [Abstract]
Principles of Consolidation [Policy Text Block]	Principles of Consolidation
	The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates
	The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to 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 period. Management evaluates estimates on a regular basis including those relating to revenue recognition, the allowance for doubtful accounts, goodwill, intangible assets, the valuation of deferred income taxes, stock-based compensation and unrecognized tax benefits, among others. Actual results could differ from those estimates and such differences may have a material impact on the Company’s condensed consolidated financial statements and footnotes.
Significant Accounting Policies [Text Block]	Significant Accounting Policies
	The Company’s significant accounting policies are described in Note 2 of the Notes to Consolidated Financial Statements in its 2014 Form 10-K. There have been no significant changes to these policies.
Comprehensive Income [Policy Text Block]	Comprehensive Income
	Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes certain changes in equity that are excluded from net income, specifically unrealized gains (losses) on available-for-sale investments. Except for net realized gain on investments which was not significant, there were no reclassifications out of accumulated other comprehensive income (loss) that affected net income during the three months ended March 31, 2015 and 2014
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 also requires significantly expanded disclosures about revenue recognition. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. On April 29, 2015, the FASB issued a proposed ASU to defer the effective date of ASU 2014-09. Under the proposal, ASU 2014-09 will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, but entities will be permitted to early adopt the standard as of the original effective date. The Company has not yet developed an expectation of the impact that adoption will have on its consolidated financial statements.
	In April 2015, the FASB issued ASU No. 2015-05, Intangibles—Goodwill and Other—Internal-Use Software (“ASU 2015-05”), which clarifies the circumstances under which a cloud computing customer would account for the arrangement as a license of internal-use software. ASU 2015-05 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. The Company has not yet developed an expectation of the impact that adoption will have on its consolidated financial statements.
