Standard-mileage deduction
-
Show the math
The standard mileage method multiplies miles by the IRS rate:
deduction = miles × rate per mile
Uses 2025 IRS standard mileage rates: business 70¢, medical & moving 21¢, charity 14¢ per mile. Business and medical mileage need a log; the actual-expense method may give a larger deduction. Estimate only, not tax advice. All math runs locally in your browser.
What this does
A mileage deduction calculator works out your standard-mileage tax deduction for business, medical, moving, or charitable driving using the current IRS rates.
How it works
Each category has its own per-mile rate. Multiplying your qualifying miles by that rate gives the deduction. The standard rate bundles fuel, repairs, and depreciation into one figure.
Deduction = miles × IRS rate
How to use it
- Choose the driving category.
- Enter your qualifying miles.
- Read your standard-mileage deduction.
- Keep a contemporaneous mileage log.
Understanding your result
The standard rate is simplest, but tracking actual costs sometimes yields a larger deduction, you generally choose one method. The IRS requires a log of dates, miles, and purpose.
Example
At the 2025 business rate of 70¢, 5,000 business miles is a $3,500 deduction.
