Accounting Policies [Abstract]
Basis of presentation	Basis of presentation. The accompanying unaudited consolidated financial statements of Polaris Inc. (“Polaris” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States for interim financial statements and, therefore, do not include all information and disclosures of results of operations, financial position and changes in cash flow in conformity with accounting principles generally accepted in the United States for complete financial statements. Accordingly, such statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 previously filed with the Securities and Exchange Commission (“SEC”). In the opinion of management, such statements reflect all adjustments (which include only normal recurring adjustments) necessary for a fair presentation of the financial position, results of operations, equity, and cash flows for the periods presented. Due to the seasonality trends for certain products and to certain changes in production and shipping cycles, results of such periods are not necessarily indicative of the results to be expected for the complete year.
Fair value measurements	Fair value measurements. Fair value is the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. In making fair value measurements, observable market data must be used when available. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. The Company utilizes the market approach to measure fair value for its non-qualified deferred compensation assets and liabilities, and the income approach for foreign currency contracts and interest rate contracts. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities, and for the income approach, the Company uses significant other observable inputs to value its derivative instruments used to hedge foreign currency and interest rate transactions.
Inventories	Inventories. Inventory costs include material, labor and manufacturing overhead costs, including depreciation expense associated with the manufacture and distribution of the Company’s products. Inventories are stated at the lower of cost (first-in, first-out method) or net realizable value.
Product warranties	Product warranties. The Company typically provides a limited warranty for its vehicles and boats for a period of six months to ten years, depending on the product. Polaris provides longer warranties in certain geographical markets as determined by local regulations and customary practice and may also provide longer warranties related to certain promotional programs. The Company’s standard warranties require the Company, generally through its dealer network, to repair or replace defective products during such warranty periods. The warranty reserve is established at the time of sale to the dealer or distributor based on management’s best estimate using historical rates and trends. The Company records these amounts as a liability in the consolidated balance sheet until they are ultimately paid. Adjustments to the warranty reserve are made based on actual claims experience in order to properly estimate the amounts necessary to settle future and existing claims on products sold as of the balance sheet date. The warranty reserve includes the estimated costs related to recalls, which are accrued when probable and estimable. Factors that could have an impact on the warranty reserve include the following: changes in manufacturing quality, shifts in product mix, changes in warranty coverage periods, impacts on product usage (including weather), product recalls and changes in sales volume.
New Accounting Pronouncements	New accounting pronouncements. Income Taxes. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify the accounting for other areas of Topic 740 by clarifying and amending existing guidance. The Company adopted ASU 2019-12 on January 1, 2021. The adoption of the ASU did not have a material impact on the Company’s consolidated financial position, results of operations, equity or cash flows. Reference Rate Reform. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides practical expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The FASB also issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope in January 2021, which adds implementation guidance to clarify which optional expedients in Topic 848 may be applied to derivative instruments that do not reference LIBOR or a reference rate that is expected to be discontinued, but that are being modified as a result of the discounting transition. The ASUs may be applied through December 31, 2022 and are applicable to our contracts and hedging relationships that reference LIBOR. We are still evaluating whether to apply any of the expedients and/or exceptions included in these ASUs. There are no other new accounting pronouncements that are expected to have a significant impact on the Company’s consolidated financial statements.

Fair value measurements. Fair value is the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date:

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

In making fair value measurements, observable market data must be used when available. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.
