Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company and Basis of Presentation	The Company and Basis of Presentation The Company—NerdWallet, Inc., a Delaware corporation, was formed on December 29, 2011. NerdWallet, Inc. and its wholly-owned subsidiaries (collectively, the Company) provide consumer-driven advice about personal finance through its platform by connecting individuals and small and mid-sized businesses (SMBs) with providers of financial products. Basis of Presentation—The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and applicable rules and regulations of the U.S. Securities and Exchange Commission regarding interim financial reporting. Accordingly, the accompanying unaudited interim condensed consolidated financial statements do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with GAAP. The accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements, and include all adjustments, consisting only of normal recurring adjustments, necessary for the fair statement of the Company’s financial position and results of operations for the periods presented. The accompanying unaudited interim condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. The results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the results to be expected for the full year or any other future period. Concentrations of Credit Risk—Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. While the Company deposits cash and cash equivalents with high credit quality financial institutions, including First Citizens Bank & Trust Company (through its Silicon Valley Bank division), HSBC and JPMorgan Chase Bank, N.A., to lessen the Company’s exposure, such cash deposits may exceed federally insured limits at these financial institutions. To mitigate the risk associated with deposits exceeding federally insured limits, the Company manages exposure by utilizing deposit accounts which include sweep features to third-party money market funds, with total money market funds of $64.2 million and $75.4 million as of September 30, 2023 and December 31, 2022, respectively. Based on these facts, collectability of bank balances appears to be adequately assured. Significant Accounting Policies—During the nine months ended September 30, 2023, there have been no material changes to the Company’s significant accounting policies as disclosed in Note 1–The Company and its Significant Accounting Policies in the notes to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.
