| Accounting Policies [Abstract] | |
| Business Description and Basis of Presentation | Wells Fargo & Company is a leading financial services company. We provide a diversified set of banking, investment and mortgage products and services, as well as consumer and commercial finance, to individuals, businesses and institutions throughout the U.S., and in countries outside the U.S. When we refer to “Wells Fargo,” “the Company,” “we,” “our” or “us,” we mean Wells Fargo & Company and Subsidiaries (consolidated). Wells Fargo & Company (the Parent) is a financial holding company and a bank holding company. Our accounting and reporting policies conform with U.S. generally accepted accounting principles (GAAP) and practices in the financial services industry. For a discussion of our significant accounting policies, see Note 1 (Summary of Significant Accounting Policies) in our Annual Report on Form 10-K for the year ended December 31, 2025 (2025 Form 10-K). There were no material changes to these policies in first quarter 2026.

| Use of Estimates | To prepare the financial statements in conformity with GAAP, management must make estimates based on assumptions about future economic and market conditions (for example, unemployment, market liquidity, real estate prices, etc.) that affect the reported amounts of assets and liabilities at the date of the financial statements, income and expenses during the reporting period and the related disclosures. Although our estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. Management has made significant estimates in several areas, including: •allowance for credit losses (Note 3 (Loans and Related Allowance for Credit Losses) and Note 2 (Available-for-Sale and Held-to-Maturity Debt Securities)); •fair value measurements (Note 6 (Mortgage Banking Activities) and Note 11 (Fair Value Measurements)); •income taxes; •liability for legal actions (Note 9 (Legal Actions)); and •goodwill impairment (Note 5 (Intangible Assets and Other Assets)). Actual results could differ from those estimates. These unaudited interim financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the periods presented. These adjustments are of a normal recurring nature, unless otherwise disclosed in this Form 10-Q. The results of operations in the interim financial statements do not necessarily indicate the results that may be expected for the full year. The interim financial information should be read in conjunction with our 2025 Form 10-K.
