Mileage Reimbursement Calculator
Calculate your business, medical or charitable mileage deduction using the 2026 IRS standard mileage rates.
How the mileage reimbursement calculator works
It multiplies the miles you drove by the IRS standard mileage rate for your purpose — 72.5¢ for business, 20.5¢ for medical or military moving, or 14¢ for charitable driving in 2026 — to give your deduction or reimbursement, and shows what the same miles are worth at each rate.
Worked example: with miles driven of 1,000, the mileage reimbursement calculator shows business mileage deduction of $725.
- Miles driven
- 1,000
- 2026 IRS rate
- 72.5¢ / mile
- Purpose
- Business
- Deduction / reimbursement
- $725
The formula
Deduction = miles × 2026 IRS standard rate (business 72.5¢, medical/moving 20.5¢, charitable 14¢ per mile).

Questions about the mileage reimbursement calculator
What is the 2026 IRS mileage rate?
For 2026 it is 72.5 cents per mile for business, 20.5 cents for medical or military moving, and 14 cents for charitable driving. The business rate rose 2.5 cents from the 2025 rate of 70 cents.
Who can deduct business mileage?
The self-employed and businesses can deduct business miles at the standard rate. Employees generally cannot deduct unreimbursed business mileage under current law, though an employer can reimburse it tax-free.
Do I need a mileage log?
Yes. The IRS expects a contemporaneous record of each trip’s date, miles and purpose. Estimated or reconstructed logs are often disallowed in an audit, so track your miles as you drive.
Standard mileage rate or actual expenses?
The standard rate is simpler; the actual-expense method (gas, repairs, insurance, depreciation) can be larger for costly vehicles. To use the standard rate you must choose it the first year the car is in service.
Is the Mileage Reimbursement Calculator free to use?
Yes. Every calculator on FinCalculators is completely free, with no sign-up, login or paywall. You can run as many scenarios as you like.
