Summary of business and significant accounting policies	Oct. 31, 2015
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of business and significant accounting policies	HealthEquity, Inc. was incorporated in the state of Delaware on September 18, 2002, and was organized to offer a full range of innovative solutions for managing health care accounts (Health Savings Accounts, Health Reimbursement Arrangements, and Flexible Spending Accounts) for health plans, insurance companies, and third-party administrators. Principles of consolidation—The condensed consolidated financial statements include the accounts of HealthEquity, Inc. and its wholly owned subsidiaries, HEQ Insurance Services, Inc., and HealthEquity Advisors, LLC (collectively referred to as the "Company"). During the year ended January 31, 2015, the Company and an unrelated company formed a limited partnership for investment in and the management of early stage companies in the healthcare industry. The Company has a 22% ownership interest in such partnership accounted for using the equity method of accounting. The investment was approximately $281,000 as of October 31, 2015 and is included in other assets on the accompanying condensed consolidated balance sheet. During the three months ended October 31, 2015, the Company purchased an approximate 2% ownership interest in a limited partnership that engages in the development of technology-based financial healthcare products. The Company determined there was no significant influence and therefore the investment was accounted for using the cost method of accounting. The investment was $500,000 as of October 31, 2015 and is included in other assets on the accompanying condensed consolidated balance sheet. All significant intercompany balances and transactions have been eliminated. Basis of presentation—The accompanying condensed consolidated financial statements as of October 31, 2015 and for the three and nine months ended October 31, 2015 and 2014 are unaudited and have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and the applicable rules and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting. In the opinion of management, the interim data includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods. Certain information and note disclosures normally included in financial statements prepared in accordance with 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 January 31, 2015. The fiscal year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. Follow-on offering—On May 11, 2015, the Company closed its follow-on public offering and sold 972,500 shares of common stock at a public offering price of $25.90 per share, less the underwriters' discount. Certain selling stockholders sold 3,455,000 shares of common stock in the offering, including 380,000 shares of common stock which were issued upon the exercise of outstanding options. The Company received net proceeds of approximately $23.5 million after deducting underwriting discounts and commissions of approximately $1.0 million and other offering expenses payable by the Company of approximately $688,000. The Company did not receive any proceeds from the sale of shares by the selling stockholders other than $222,000 representing the exercise price of the options that were exercised in connection with the offering. Marketable securities—Marketable securities consist primarily of mutual funds invested in corporate bonds, U.S. government agency securities, U.S. treasury bills, commercial paper, certificates of deposit, municipal notes, and bonds with original maturities beyond three months at the time of purchase. Marketable securities are classified as available-for-sale, held-to-maturity, or trading at the date of purchase. As of October 31, 2015, all marketable securities have been classified as available-for-sale. The Company may sell these securities at any time for use in current operations or for other purposes even if they have not yet reached maturity. As a result, the Company classifies its marketable securities, including securities with maturities beyond twelve months, as current assets in the accompanying condensed consolidated balance sheets. All marketable securities are recorded at their estimated fair value. Unrealized gains and losses for available-for-sale securities are recorded in other comprehensive income. The Company evaluates its marketable securities to assess whether those with unrealized loss positions are other-than-temporarily impaired. The Company considers impairments to be other than temporary if they are related to deterioration in credit risk or if it is likely it will sell the securities before the recovery of their cost basis. Realized gains and losses and declines in value judged to be other-than-temporary are determined based on the specific identification method and are reported in other expense, net in the condensed consolidated statements of operations and comprehensive income. Recent accounting pronouncements—On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective. In July 2015, the FASB voted to defer the effective date to fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption beginning for fiscal years, and interim periods within those fiscal years, beginning after December 31, 2016. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on the consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor determined the effect of the standard on the ongoing financial reporting. In April 2015, the FASB issued ASU 2015-3, Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs, which simplifies the presentation of debt issuance costs by requiring that such costs be presented as a deduction from the corresponding debt liability. In August 2015, the FASB issued ASU 2015-15, Interest - Imputed Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements, which clarifies that entities may continue to defer and present debt issuance costs associated with a line-of-credit as an asset and subsequently amortize the deferred costs ratably over the term of the arrangement. The guidance is effective for financial statements issued for reporting periods beginning after December 15, 2015 and interim periods within the reporting periods and requires retrospective presentation; earlier adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows. In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes, which simplifies balance sheet classifications of deferred taxes by requiring all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. The net current deferred tax asset as of October 31, 2015 was $2.0 million. The Company plans to early adopt this guidance on a prospective basis in the first quarter of fiscal year 2017. Asset acquisitions—In October 2015, the Company acquired a portfolio of HSAs. The Company paid $33.8 million in cash, which was funded by cash on hand. The purchased group of assets did not include workforce or any processes and therefore did not constitute a business. Accordingly, the acquisition was accounted for under the asset acquisition method of accounting in accordance with ASC 805-50, Business Combinations—Related Issues. Under the asset acquisition method of accounting, the Company is required to fair value the assets transferred. The costs of the assets acquired is allocated to the individual assets acquired based on their relative fair values and does not give rise to goodwill. As of October 31, 2015, the purchase price of $33.8 million was allocated to acquired intangible member assets. Furthermore, transaction costs that are incurred in conjunction with an asset acquisition are allocated to the acquired intangible member assets. Business Combinations—Acquisition-related expenses incurred in conjunction with the acquisition of a business as defined by ASC 805-10 are recognized in earnings in the period in which they are incurred and are included in other expense, net on the condensed consolidated statement of operations. During the three and nine months ended October 31, 2015, the Company received a credit of $187,000 and incurred an expense of $474,000, respectively for acquisition-related activity. There were no such business combinations during the three and nine months ended October 31, 2015 and 2014.

Earnings Per Share [Abstract]

Net income per share attributable to common stockholders

The Company computed net income per share of common stock in conformity with the two-class method required for participating securities for the nine months ended October 31, 2014. Prior to their conversion to common stock, the Company considered its series D-3 redeemable convertible preferred stock to be participating securities as the holders of the preferred stock were entitled to receive a dividend in the event that a dividend was paid on common stock. The following table sets forth the computation of basic and diluted net income per share attributable to common stockholders:

For the nine months ended October 31, 2015 and 2014, approximately 726,000 and 164,000 shares, respectively, attributable to stock options were excluded from the calculation of diluted earnings per share as their inclusion would have been anti-dilutive.

These commitments as of January 31, 2015 are disclosed in the Company’s consolidated financial statements included in its Annual Report on Form 10-K for the year ended January 31, 2015, and did not change materially during the three and nine months ended October 31, 2015, except for the following: On May 15, 2015, the Company entered into a lease agreement to expand its headquarters in Draper, Utah. The lease provides for a new landlord to construct a building at its cost and to use reasonable efforts to substantially complete the building by July 2016. The Company has no risk of loss during the construction period. The lease will commence upon the substantial completion and delivery of the building to the Company and has an initial term of 129 months thereafter, with a Company option to extend the lease for two additional five year periods. The Company will be responsible for payment of taxes and operating expenses for its portion of the building, in addition to an annual base rent in the initial amount of approximately $1.0 million, with 2.5% annual increases. In conjunction with the aforementioned lease, the Company entered into an amended and restated lease agreement for its existing office space at its headquarters in Draper, Utah. The lease commenced on July 1, 2015 and has an initial term of 129 months thereafter, with a Company option to extend the lease for two additional five year periods. The Company will be responsible for payment of taxes and operating expenses for its portion of the building, in addition to an annual base rent in the initial amount of approximately $1.6 million, with 2.5% annual increases. As a result of the foregoing transaction, the deferred rent balance of approximately $470,000 was reversed during the nine months ended October 31, 2015. Lease expense for office space for the three and nine months ended October 31, 2015 was $556,000 and $1.6 million, respectively, and $374,000 and $944,000 for the three and nine months ended October 31, 2014, respectively. Expense for other lease agreements for the three and nine months ended October 31, 2015 was $66,000 and $182,000, respectively, and $67,000 and $166,000 for the three and nine months ended October 31, 2014, respectively.

Indebtedness	9 Months Ended
Indebtedness	Oct. 31, 2015
Debt Disclosure [Abstract]
Indebtedness	On September 30, 2015, the Company entered into a new credit facility (the "Credit Agreement"). The Credit Agreement provides for a secured revolving credit facility in the aggregate principal amount of $100.0 million for a term of five years. The proceeds of borrowings under the Credit Agreement may be used for general corporate purposes. No amounts have been drawn under the Credit Agreement as of October 31, 2015. Borrowings under the Credit Agreement bear interest equal to, at the Company's option, a) an adjusted LIBOR rate or b) a customary base rate, in each case with an applicable spread to be determined based on the Company's leverage ratio as of the most recent fiscal quarter. The applicable spread for borrowing under the Credit Agreement will range from 1.50% to 2.00% with respect to adjusted LIBOR rate borrowings and 0.50% to 1.00% with respect to customary base rate borrowings. Additionally, the Company will pay a commitment fee ranging from 0.20% to 0.30% on the daily amount of the unused commitments under the Credit Agreement payable in arrears at the end of each fiscal quarter. The Company's material subsidiaries will be required to guarantee the obligations of the Company under the Credit Agreement. The obligations of the Company and the guarantors under the Credit Agreement and the guarantees will be secured by substantially all assets of the Company and the guarantors, subject to customary exclusions and exceptions. The Credit Agreement requires the Company to maintain a total leverage ratio of not more than 3.00 to 1.00 as of the end of each fiscal quarter and a minimum interest coverage ratio of at least 3.00 to 1.00 as of the end of each fiscal quarter. In addition, the Credit Agreement includes customary representations and warranties, affirmative and negative covenants, and events of default. The restrictive covenants include customary restrictions on the Company's ability to incur additional indebtedness; make investments, loans or advances; grant or incur liens on assets; engage in mergers, consolidations, liquidations or dissolutions; engage in transactions with affiliates; and make dividend payments. In connection with the Credit Agreement, the Company incurred $303,000 in financing costs, which are deferred and are being amortized using the straight-line method, which approximates the effective interest method, over the life of the agreement.

Income taxes	9 Months Ended
Income taxes	Oct. 31, 2015
Income Tax Disclosure [Abstract]
Income taxes	The Company follows FASB Accounting Standards Codification 740-270, Income Taxes - Interim Reporting, for the computation and presentation of its interim period tax provision. Accordingly, management estimated the effective annual tax rate and applied this rate to the year-to-date pre-tax book income to determine the interim provision for income taxes. For the three and nine months ended October 31, 2015, the Company recorded a provision for income taxes of $2.3 million and $7.8 million, respectively. The resulting effective tax rate was 36.4% and 36.6%, compared with an effective tax rate of 26.5% and 36.5% for the three and nine months ended October 31, 2014. For the three and nine months ended October 31, 2015, discrete tax items were not significant. For the three and nine months ended October 31, 2014, the net impact of discrete tax items caused a 12.1% and 3.1% decrease, respectively, to the effective tax rate primarily due to the recognition of research and development tax credits, book stock compensation expense on stock options vesting upon the Company's initial public offering, or IPO, treated as a discrete event, and the impact of changes in estimated annual tax rates. The federal research and development tax credit expired as of December 31, 2014. As of October 31, 2015 and January 31, 2015, the Company’s total gross unrecognized tax benefit was $329,000 and $300,000, respectively. As a result of Accounting Standards Update No. 2013-11, certain unrecognized tax benefits have been netted against their related deferred tax assets. As a result, the unrecognized tax benefit recorded as of October 31, 2015 and January 31, 2015 remains unchanged at $20,000. If recognized, $248,000 of the total gross unrecognized tax benefits would affect the Company's effective tax rate as of October 31, 2015. The Company anticipates a decrease of $20,000 in total gross unrecognized tax benefits within 12 months of the reporting date related to uncertain tax positions on research and development credits claimed and the untimely filing of certain elections for which a lapse of the applicable statute of limitations is expected. The Company files income tax returns with U.S. federal and state taxing jurisdictions and is not currently under examination with any jurisdiction. The Company remains subject to examination by federal and various state taxing jurisdictions for tax years after 2003.

Stock options

Stock option activity under the Company's equity incentive plans is as follows:



	Outstanding stock options
(in thousands, except for exercise prices and term)	Number of options		Range of exercise prices	Weighted- average exercise price		Weighted- average contractual term (in years)	Aggregate intrinsic value
Outstanding as of January 31, 2015	6,457		$0.10 - 25.45	$	5.27	6.88	$	100,290

Exercisable as of October 31, 2015	2,615			$	2.09	5.22	$	80,095

The aggregate intrinsic value in the table above represents the difference between the estimated fair value of common stock and the exercise price of outstanding, in-the-money stock options.

The key input assumptions that were utilized in the valuation of the stock options granted during the periods presented:



	Three months ended October 31,				Nine months ended October 31,
	2015		2014		2015		2014
Expected dividend yield	—	%	—	%	—	%	—%
Expected stock price volatility	38.4	%	32.9	%	38.4% - 40.3%		32.9%
Risk-free interest rate	1.56% - 1.70%		1.93	%	1.47% - 1.72%		1.93% - 2.24%
Expected life of options	6.25 years		6.25 years		5.43 - 6.25 years		6.25 years

The determination of the fair value of stock options on the date of grant using an option pricing model is affected by the Company's stock price as well as assumptions regarding a number of complex and subjective variables. Expected volatility is determined using weighted average volatility of publicly traded peer companies. The Company expects that it will begin using its own historical volatility in addition to the volatility of publicly traded peer companies, as its share price history grows over time. The risk-free interest rate is determined by using published zero coupon rates on treasury notes for each grant date given the expected term on the options. The dividend yield of zero is based on the fact that the Company expects to invest cash in operations. The Company uses the "simplified" method to estimate expected term as determined under Staff Accounting Bulletin No. 110 due to the lack of sufficient option exercise history as a public company.

As of October 31, 2015, the weighted-average vesting period of non-vested awards expected to vest approximates 2.6 years; the amount of compensation expense the Company expects to recognize for stock options vesting in future periods approximates $14.7 million.

The following table shows a summary of stock-based compensation in the Company's condensed consolidated statements of operations and comprehensive income during the periods presented:

Fair Value Disclosures [Abstract]

Fair value

Fair value measurements—Fair value measurements are made at a specific point in time, based on relevant market information. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Accounting standards specify a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs have created the following fair value hierarchy:


•	Level 1—quoted prices in active markets for identical assets or liabilities;


•	Level 2—inputs, other than the quoted prices in active markets, that are observable either directly or indirectly;


•	Level 3—unobservable inputs based on the Company’s own assumptions.

Level 1 instruments are valued based on publicly available daily net asset values. Level 1 instruments consist primarily of highly liquid mutual funds.

The following table summarizes the assets measured at fair value on a recurring basis and indicates the level within the fair value hierarchy reflecting the valuation techniques utilized to determine fair value:



	October 31, 2015
(in thousands)	Level 1		Level 2		Level 3
Marketable securities:
Mutual funds	$	40,105	$	—	$	—

A derivative liability was recorded related to the Company’s series D-3 redeemable convertible preferred stock due to stated features allowing for redemption equal to the greater of the fair value per share of series D-3 redeemable convertible preferred stock, or the liquidation preference per share of series D-3 redeemable convertible preferred stock. The derivative instrument was recorded at its fair value, using an option pricing model, and was adjusted to fair value as of the end of each reporting period. Changes in the fair value of derivative instruments are recognized currently in the condensed consolidated financial statements. The Company had classified this derivative financial instrument as Level 3 in the fair value hierarchy. The Company continued to record adjustments to the fair value of the derivative liability until March 31, 2014, at which time the Company modified the terms of the series D-3 redeemable convertible preferred stock. As a result of the modifications, the Company reclassified the aggregate fair value of the liability to additional paid-in capital.

The following table includes a roll forward of the amounts for the three and nine months ended October 31, 2015 and 2014 for instruments classified within Level 3. The classification within Level 3 is based upon significance of the unobservable inputs to the overall fair value measurement.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of consolidation	Principles of consolidation—The condensed consolidated financial statements include the accounts of HealthEquity, Inc. and its wholly owned subsidiaries, HEQ Insurance Services, Inc., and HealthEquity Advisors, LLC (collectively referred to as the "Company"). During the year ended January 31, 2015, the Company and an unrelated company formed a limited partnership for investment in and the management of early stage companies in the healthcare industry. The Company has a 22% ownership interest in such partnership accounted for using the equity method of accounting. The investment was approximately $281,000 as of October 31, 2015 and is included in other assets on the accompanying condensed consolidated balance sheet. During the three months ended October 31, 2015, the Company purchased an approximate 2% ownership interest in a limited partnership that engages in the development of technology-based financial healthcare products. The Company determined there was no significant influence and therefore the investment was accounted for using the cost method of accounting. The investment was $500,000 as of October 31, 2015 and is included in other assets on the accompanying condensed consolidated balance sheet. All significant intercompany balances and transactions have been eliminated.
Marketable securities	Marketable securities—Marketable securities consist primarily of mutual funds invested in corporate bonds, U.S. government agency securities, U.S. treasury bills, commercial paper, certificates of deposit, municipal notes, and bonds with original maturities beyond three months at the time of purchase. Marketable securities are classified as available-for-sale, held-to-maturity, or trading at the date of purchase. As of October 31, 2015, all marketable securities have been classified as available-for-sale. The Company may sell these securities at any time for use in current operations or for other purposes even if they have not yet reached maturity. As a result, the Company classifies its marketable securities, including securities with maturities beyond twelve months, as current assets in the accompanying condensed consolidated balance sheets. All marketable securities are recorded at their estimated fair value. Unrealized gains and losses for available-for-sale securities are recorded in other comprehensive income. The Company evaluates its marketable securities to assess whether those with unrealized loss positions are other-than-temporarily impaired. The Company considers impairments to be other than temporary if they are related to deterioration in credit risk or if it is likely it will sell the securities before the recovery of their cost basis. Realized gains and losses and declines in value judged to be other-than-temporary are determined based on the specific identification method and are reported in other expense, net in the condensed consolidated statements of operations and comprehensive income.
Recent accounting pronouncements	Recent accounting pronouncements—On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective. In July 2015, the FASB voted to defer the effective date to fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption beginning for fiscal years, and interim periods within those fiscal years, beginning after December 31, 2016. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on the consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor determined the effect of the standard on the ongoing financial reporting. In April 2015, the FASB issued ASU 2015-3, Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs, which simplifies the presentation of debt issuance costs by requiring that such costs be presented as a deduction from the corresponding debt liability. In August 2015, the FASB issued ASU 2015-15, Interest - Imputed Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements, which clarifies that entities may continue to defer and present debt issuance costs associated with a line-of-credit as an asset and subsequently amortize the deferred costs ratably over the term of the arrangement. The guidance is effective for financial statements issued for reporting periods beginning after December 15, 2015 and interim periods within the reporting periods and requires retrospective presentation; earlier adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows. In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes, which simplifies balance sheet classifications of deferred taxes by requiring all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. The net current deferred tax asset as of October 31, 2015 was $2.0 million. The Company plans to early adopt this guidance on a prospective basis in the first quarter of fiscal year 2017.

- Definition

Cash includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the customer may deposit additional funds at any time and effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid Investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Short-term investments, exclusive of cash equivalents, generally consist of marketable securities intended to be sold within one year (or the normal operating cycle if longer) and may include trading securities, available-for-sale securities, or held-to-maturity securities (if maturing within one year), as applicable.
