| 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, First HSA, LLC, First Horizon MSaver, Inc., HEQ Insurance Services, Inc., and HealthEquity Advisors, LLC (collectively referred to as the "Company"). All significant intercompany balances and transactions have been eliminated. | |
| Basis of presentation—The accompanying condensed consolidated financial statements as of July 31, 2014 and for the six months ended July 31, 2014 and 2013 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 final prospectus (dated July 30, 2014) filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933 on August 1, 2014. | |
| The fiscal year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. | |
| Initial public offering—On August 5, 2014, the Company consummated its initial public offering ("IPO") and issued and sold 10,465,000 shares of its common stock at a public offering price of $14.00 per share, less the underwriters' discount. The Company received net proceeds of approximately $132.5 million after deducting underwriters' discounts and commissions of approximately $10.3 million and other offering expenses payable by the Company of approximately $3.7 million, of which approximately $1.4 million of the other offering expenses had been paid as of July 31, 2014. The underwriting discounts and commissions and other offering expenses were recorded as an offset against the IPO proceeds in additional paid-in capital upon the closing of the IPO on August 5, 2014. The net proceeds and other impacts of the IPO described herein are not reflected in the condensed consolidated financial statements as of July 31, 2014, as the Company consummated its IPO and received the proceeds subsequent to the end of the second fiscal quarter of 2015. | |
| 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 U.S. GAAP when it becomes effective. The new standard is effective for our annual and interim reporting periods beginning February 1, 2017. Early application is not permitted. 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. |

| Commitments and contingencies | |
| The Company’s principal commitments and contingencies consist of a processing services agreement with a vendor, and obligations for office space, data storage facilities, equipment and certain maintenance agreements under long-term, non-cancelable operating leases. These commitments as of January 31, 2014 are disclosed in the Company’s consolidated financial statements included in its final prospectus (dated July 30, 2014) filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933 on August 1, 2014, and did not change materially during the three and six months ended July 31, 2014 except for the following: | |
| In March 2014, the Company modified its corporate office lease to expand its existing space for an additional commitment of $1.1 million over the term of the original lease. | |
| Lease expense for office space for the three and six months ended July 31, 2014 and 2013 totaled $293,000, $222,000, $570,000 and $435,000, respectively.

| 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 six months ended July 31, 2014, the Company recorded a provision for income taxes of $2.0 million and $3.9 million, respectively. The resulting effective tax rate was 39.8% and 40.7%, compared with an effective tax rate of 37.8% and 38.1% for the three and six months ended July 31, 2013, respectively. For the three and six months ended July 31, 2014, the net impact of discrete tax items caused a 1.3% and 0.5% decrease to the effective tax rate primarily due to the tax benefit on book stock compensation expense on stock options vesting upon the Company’s initial public offering, partially offset by changes in tax rates on the Company’s deferred tax assets and liabilities. For the three and six months ended July 31, 2013, the net impact of discrete tax items was not material. The effective tax rate increased over the same period last year primarily due to an increase in permanent tax items in relation to income before income taxes, expiration of the federal research and development tax credits as of December 31, 2013, and discrete tax items. | |
| As of July 31, 2014 and January 31, 2014, the Company’s total gross unrecognized tax benefit was $264,000 and $256,000, 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 July 31, 2014 and January 31, 2014 remains unchanged in the amount of $47,000. Substantially all of the gross unrecognized tax benefit, if recognized, would affect the Company’s effective tax rate. The Company anticipates a decrease of $22,000 in total gross unrecognized tax benefits within 12 months of the reporting date related to an uncertain tax position on research and development credits claimed 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 2002. |

| On January 30, 2014, the Company’s board of directors approved and the Company adopted a 2014 Equity Incentive Plan (the "Incentive Plan") providing for the issuance of stock options to the directors and employees of the Company to purchase up to an aggregate of 600,000 shares of common stock. No stock options were issued to directors of the Company from the Incentive Plan as of January 31, 2014. | |||||||||||||||||||||
| In July 2014, the Company's board of directors voted to increase the shares of common stock reserved under the Incentive Plan by 2,000,000 shares from 600,000 shares of common stock to 2,600,000 shares of common stock. In addition, the board of directors voted to provide that the number of shares of common stock reserved for issuance under the Incentive Plan will automatically increase on February 1 of each year, beginning as of February 1, 2015 and continuing through and including February 1, 2024, by 3% of the total number of shares of the Company’s capital stock outstanding on January 31 of the preceding fiscal year, or a lesser number of shares determined by the board of directors. As of July 31, 2014, 623,000 shares were available for grant under the Incentive Plan. | |||||||||||||||||||||
| Under the terms of the Incentive Plan, the Company has the ability to grant incentive and nonstatutory stock options. Incentive stock options may be granted only to Company employees. Nonstatutory stock options may be granted to Company employees, directors and consultants. Such options are to be exercisable at prices, as determined by the board of directors, which must be equal to no less than the fair value of the Company's common stock at the date of the grant. Stock options granted under the Incentive Plan generally expire 10 years from the date of issuance, or are forfeited 90 days after termination of employment. Any stock options that are forfeited or that expire are returned to the Incentive Plan. | |||||||||||||||||||||

In addition, upon the pricing of the IPO, the Company granted 1.4 million performance-based stock options to certain key employees under the Incentive Plan, which vest upon the achievement of certain performance criteria.

The amended and restated certificate of incorporation was filed with the Secretary of State of the State of Delaware and became effective on August 5, 2014. | |
| On July 14, 2014, the Company's board of directors declared a cash dividend in an aggregate amount of $50 million on shares of the Company's common stock outstanding on August 4, 2014 (after giving effect to the conversion of all outstanding convertible preferred stock and redeemable convertible preferred stock into shares of common stock). The terms of each of the Company's stock plans, including, the 2003 Director Stock Plan, 2003 Stock Plan, 2005 Stock Plan, 2006 Stock Plan, 2009 Stock Plan and the Incentive Plan requires an adjustment to outstanding stock options to prevent dilution of the holders’ interests as a result of the foregoing special dividend. Accordingly, the Company's board of directors approved an adjustment to reduce the exercise price of each of the stock options outstanding as of the record date, August 4, 2014, for the dividend by $1.00. | |
| As of the close of business on August 4, 2014, all of the Company's redeemable convertible preferred stock and convertible preferred stock was converted into 32,486,588 shares of common stock. | |
| On August 5, 2014, the Company consummated its IPO and issued and sold 10,465,000 shares of common stock at a public offering price of $14.00 per share, less the underwriters' discount. The shares began trading on the NASDAQ Global Select Market on July 31, 2014. The Company received net proceeds of approximately $132.5 million after deducting underwriting discounts and commissions of approximately $10.3 million and other offering expenses payable by the Company of approximately $3.7 million, of which approximately $1.4 million of the other offering expenses had been paid as of July 31, 2014. The underwriting discounts and commissions and other offering expenses were recorded as an offset against the IPO proceeds in additional paid-in capital upon the closing of the IPO on August 5, 2014. | |
| The net proceeds and other impacts of the IPO described above are not reflected in the condensed consolidated financial statements as of July 31, 2014, as the Company consummated its IPO and received the proceeds subsequent to the end of the second fiscal quarter of 2015. |

| 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 U.S. GAAP when it becomes effective. The new standard is effective for our annual and interim reporting periods beginning February 1, 2017. Early application is not permitted. 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 |
