Add each business trip with its date, purpose and either the start and end odometer readings or the miles driven. The calculator applies the IRS business standard mileage rate for each trip's date and totals everything. You can edit the rates.
Not tax advice. This tool does arithmetic on the numbers you enter. Whether a trip or payment counts, which rate or threshold applies, and how to report it depend on your situation. Check with a tax professional or the IRS pages linked here.
Rates from the IRS standard mileage rates page (checked Oct 31, 2026). For 2026 the IRS published two rates: 72.5 cents per mile for Jan. 1 – June 30 (IR-2025-128) and 76 cents per mile for July 1 – Dec. 31 (IR-2026-29). Edit a rate if it changes or if you need a different one.
Free to add to your blog or resource page. Copy this snippet. The calculator runs in your readers' browsers, nothing they enter is uploaded, and it includes a small credit link back here.
