Accounting Policies [Abstract]
Use of Estimates	We have made estimates and judgments affecting the amounts reported in our Condensed Consolidated Financial Statements and the accompanying notes. The actual results that we experience may differ materially from our estimates. The interim financial information is unaudited, and reflects all normal adjustments that are, in our opinion, necessary to provide a fair statement of results for the interim periods presented. This report should be read in conjunction with our 2020 Form 10-K where we include additional information about our significant accounting policies and the methods and assumptions used in our estimates.
Recently Adopted Accounting Pronouncements/Recently Issued Account Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements Income Taxes - Simplifying the Accounting for Income Taxes In December 2019, the Financial Accounting Standards Board (FASB) issued amendments to the accounting for Income Taxes to reduce complexity by removing certain exceptions and implementing targeted simplifications. We adopted the new standard on a prospective basis at the beginning of fiscal year 2021. The adoption did not have a material impact on our Condensed Consolidated Financial Statements.
Product Warranties	We accrue for warranty costs as part of our cost of sales based on associated material product costs, technical support, labor costs, and costs incurred by third parties performing work on our behalf. Our expected future costs are primarily estimated based upon historical trends in the volume of product returns within the warranty period and the costs to repair or replace the equipment. When products sold include warranty provisions, they are covered by a warranty for periods ranging generally from one year to two years.
Earnings Per Share	Basic earnings per share is computed by dividing net income attributable to Trimble Inc. by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing net income attributable to Trimble Inc. by the weighted-average number of shares of common stock outstanding during the period, increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options, shares to be purchased under the Company’s employee stock purchase plan, restricted stock units, and contingently issuable shares.

Income Taxes - Simplifying the Accounting for Income Taxes

In December 2019, the Financial Accounting Standards Board (FASB) issued amendments to the accounting for Income Taxes to reduce complexity by removing certain exceptions and implementing targeted simplifications. We adopted the new standard on a prospective basis at the beginning of fiscal year 2021. The adoption did not have a material impact on our Condensed Consolidated Financial Statements.

Product Warranties

We accrue for warranty costs as part of our cost of sales based on associated material product costs, technical support, labor costs, and costs incurred by third parties performing work on our behalf. Our expected future costs are primarily estimated based upon historical trends in the volume of product returns within the warranty period and the costs to repair or replace the equipment. When products sold include warranty provisions, they are covered by a warranty for periods ranging generally from one year to two years.

Earnings Per Share

Basic earnings per share is computed by dividing net income attributable to Trimble Inc. by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing net income attributable to Trimble Inc. by the weighted-average number of shares of common stock outstanding during the period, increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options, shares to be purchased under the Company’s employee stock purchase plan, restricted stock units, and contingently issuable shares.
