Accounting Policies [Abstract]
Principles of Consolidation and Significant Accounting Policies	Principles of Consolidation and Significant Accounting Policies The accompanying condensed consolidated financial statements, which include the accounts of Nutanix, Inc. and its wholly-owned subsidiaries, have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP") and are consistent in all material respects with those included in our Annual Report on Form 10-K for the fiscal year ended July 31, 2018, filed with the Securities and Exchange Commission ("SEC") on September 24, 2018. All intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated financial statements are unaudited, but include all adjustments of a normal recurring nature necessary for a fair presentation of our quarterly results. Certain reclassifications have been made to the prior year financial statements to conform to the current year presentation. These reclassifications had no impact on the previously reported net loss or accumulated deficit. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes in our Annual Report on Form 10-K for the fiscal year ended July 31, 2018.
Use of Estimates	Use of Estimates The preparation of interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Such management estimates include, but are not limited to, the best estimate of selling prices for products and related support; useful lives of intangible assets and property and equipment; allowance for doubtful accounts; determination of fair value of stock-based awards; accounting for income taxes, including the valuation allowance on deferred tax assets and uncertain tax positions; warranty liability; fair value of contingent consideration in a business combination; sales commissions expense; and contingencies and litigation. Management evaluates these estimates and assumptions on an ongoing basis using historical experience and other factors and makes adjustments when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could materially differ from those estimates and assumptions.
Concentration Risk	Concentration of Risk Concentration of revenue and accounts receivable—We sell our products primarily through our Partners and occasionally directly to end customers. For the three and nine months ended April 30, 2018 and 2019, no end customer accounted for more than 10% of total revenue or accounts receivable.
Recently Issued and Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In October 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which requires us to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The new standard was effective for fiscal years beginning after December 15, 2017, with early adoption permitted, including interim reporting periods within those fiscal years. We adopted this ASU effective August 1, 2018 using a modified retrospective approach. The adoption of the new standard did not have a material impact on our condensed consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash or restricted cash equivalents should be included with cash and cash equivalents when reconciling beginning-of-period and end-of-period amounts shown on the statement of cash flows. The new standard was effective for fiscal years beginning after December 15, 2017, with early adoption permitted, including interim reporting periods within those fiscal years. We adopted the new standard effective August 1, 2018, using the retrospective transition approach. The reclassified restricted cash balances from operating activities to changes in cash, cash equivalents and restricted cash on the condensed consolidated statements of cash flows were not material for any period presented. In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which aligns the accounting for share-based payment awards issued to nonemployees with the guidance applicable to grants to employees. Under the new standard, equity-classified share-based payment awards issued to nonemployees will be measured on the grant date, instead of the current requirement to remeasure the awards through the performance completion date. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including interim reporting periods within those fiscal years. We early adopted the standard effective August 1, 2018, using the prospective approach, and our adoption did not have a material impact on the condensed consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other (Topic 350): Internal-Use Software, which standard aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including interim reporting periods within those fiscal years. We early adopted the standard effective August 1, 2018, using the prospective approach, and our adoption did not have a significant impact on our condensed consolidated financial statements. In August 2018, the SEC issued Securities Act Release No. 33-10532, which amends certain disclosure requirements, including extending to interim periods the annual requirement to disclose changes in stockholders’ equity. Under the new requirements, registrants must now analyze changes in stockholders’ equity, in the form of a reconciliation, for the current and comparative year-to-date interim periods, with subtotals for each interim period. The final rule was effective in November 2018. We adopted this new guidance during the first quarter of fiscal 2019 and have included a reconciliation of the changes in stockholders' equity in this Quarterly Report on Form 10-Q. Recently Issued and Not Yet Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases, which requires the recognition of right-of-use lease assets and lease liabilities for all leases, except for short-term leases, on the condensed consolidated balance sheets of lessees. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including interim reporting periods within those fiscal years. We will adopt the standard effective August 1, 2019 and we intend to elect certain practical expedients, including the transition option that will allow us to not have to restate the comparative periods in our condensed consolidated financial statements in the year of adoption. We currently anticipate that the adoption of this standard will have a material impact on our condensed consolidated balance sheets, given that we had operating lease commitments in excess of $175 million as of April 30, 2019, on an undiscounted basis. We expect that most of our operating lease commitments will be subject to the new standard and will be recognized as lease liabilities and right-of-use assets upon adoption, which will increase our total assets and total liabilities reported. However, we do not anticipate that the adoption of this standard will have a material impact on our condensed consolidated statements of operations, as the expense recognition under the new standard will be similar to current practice. We do not expect the adoption of this standard to have a material impact on our condensed consolidated statements of cash flows. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which provides companies with an option to reclassify stranded tax effects resulting from the enactment of the Tax Cuts and Jobs Act ("TCJA") from accumulated other comprehensive income to retained earnings. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including interim reporting periods within those fiscal years, and will be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the tax rate as a result of TCJA is recognized. We have not made a determination as to which alternative method we will use upon adoption of the standard, but we do not expect the adoption of this ASU to have a material impact on our condensed consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement, which eliminates, adds and modifies certain disclosure requirements for fair value measurements as part of the FASB's disclosure framework project. The new standard is effective for fiscal years beginning after December 15, 2019, with early adoption permitted, including interim reporting periods within those fiscal years. We do not expect the adoption of this ASU to have a significant impact on our quarterly or annual disclosures.
Revenue Recognition	We generate revenue primarily from the sale of our enterprise cloud platform, which can be delivered pre-installed on an appliance that is configured to order or delivered separately to be utilized on a variety of certified hardware platforms. Software delivered on configured to order appliances is not portable to other appliances and has a term equal to the life of the associated appliance, while subscription term-based licenses typically have a term of one to five years. Configured to order appliances, including our Nutanix-branded NX hardware line, are typically sold through Partners and can be purchased from one of our OEMs or directly from Nutanix. Our platform is typically purchased with one or more years of support and entitlements, which includes the right to software upgrades and enhancements as well as technical support. A substantial portion of sales are made through channel partners and OEM relationships.

Principles of Consolidation and Significant Accounting Policies

The accompanying condensed consolidated financial statements, which include the accounts of Nutanix, Inc. and its wholly-owned subsidiaries, have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP") and are consistent in all material respects with those included in our Annual Report on Form 10-K for the fiscal year ended July 31, 2018, filed with the Securities and Exchange Commission ("SEC") on September 24, 2018.

The condensed consolidated financial statements are unaudited, but include all adjustments of a normal recurring nature necessary for a fair presentation of our quarterly results. Certain reclassifications have been made to the prior year financial statements to conform to the current year presentation. These reclassifications had no impact on the previously reported net loss or accumulated deficit.

These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes in our Annual Report on Form 10-K for the fiscal year ended July 31, 2018.

Use of Estimates

The preparation of interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Such management estimates include, but are not limited to, the best estimate of selling prices for products and related support; useful lives of intangible assets and property and equipment; allowance for doubtful accounts; determination of fair value of stock-based awards; accounting for income taxes, including the valuation allowance on deferred tax assets and uncertain tax positions; warranty liability; fair value of contingent consideration in a business combination; sales commissions expense; and contingencies and litigation. Management evaluates these estimates and assumptions on an ongoing basis using historical experience and other factors and makes adjustments when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could materially differ from those estimates and assumptions.

Concentration Risk

Concentration of Risk

Concentration of revenue and accounts receivable—We sell our products primarily through our Partners and occasionally directly to end customers. For the three and nine months ended April 30, 2018 and 2019, no end customer accounted for more than 10% of total revenue or accounts receivable.
