Accounting Policies [Abstract]
Summary of Accounting Policies	Summary of Accounting Policies Principles of consolidation and presentation: The Condensed Consolidated Financial Statements include the accounts of Snap-on Incorporated and its wholly owned and majority-owned subsidiaries (collectively, “Snap-on” or the “company”). These financial statements should be read in conjunction with, and have been prepared in conformity with, the accounting principles reflected in the consolidated financial statements and related notes included in Snap-on’s 2024 Annual Report on Form 10-K for the fiscal year ended December 28, 2024 (“2024 year end”). The company’s 2025 fiscal year, which ends on January 3, 2026, will contain 53 weeks of operating results, with the additional week occurring in the fourth quarter. The company’s 2024 fiscal year contained 52 weeks of operating results. The company’s 2025 fiscal first quarter ended on March 29, 2025, and its 2024 fiscal first quarter ended on March 30, 2024. The company’s 2025 and 2024 fiscal first quarters each contained 13 weeks of operating results. Snap-on’s Condensed Consolidated Financial Statements are prepared in conformity with generally accepted accounting principles in the United States of America (“GAAP”). In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for the fair presentation of the Condensed Consolidated Financial Statements for the three month periods ended March 29, 2025, and March 30, 2024, have been made. Interim results of operations are not necessarily indicative of the results to be expected for the full fiscal year. Use of estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Financial instruments: The fair value of the company’s derivative financial instruments is generally determined using quoted prices in active markets for similar assets and liabilities. The carrying value of the company’s non-derivative financial instruments either approximates fair value, due to their short-term nature, or the amount disclosed for fair value is based upon a discounted cash flow analysis or quoted market values. See Note 8 for additional information on financial instruments. New accounting standards: In November 2024, the FASB issued ASU No. 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires disaggregated expense information in the notes to the financial statements related to purchases of inventory, employee compensation, depreciation, intangible asset amortization and selling expenses for each statement of earnings line item that contains those expenses. ASU No. 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027. The guidance is to be applied on a prospective basis with the option to apply the standard retrospectively; this ASU allows for early adoption. The adoption of this ASU is not expected to have a material impact on Snap-on’s Condensed Consolidated Financial Statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. ASU No. 2023-09 is effective for annual periods beginning after December 15, 2024. The guidance is to be applied on a prospective basis with the option to apply the standard retrospectively; this ASU allows for early adoption. The adoption of this ASU is not expected to have a material impact on Snap-on’s Condensed Consolidated Financial Statements.
