Mileage Reimbursement Calculator
Enter your trip miles and PerDiemWise multiplies them by the 2026 IRS standard mileage rate for your trip date — 72.5¢ for business before July 1 and 76¢ from July 1, 20.5¢ for medical or moving (23.5¢ from July 1), and 14¢ for charitable driving. Add multiple legs to total a whole trip.
Driving for work — the most common reimbursement rate.
About the mileage reimbursement calculator
The IRS sets an optional standard mileage rate each year to value the deductible or reimbursable cost of running a personal vehicle for business, medical, moving or charitable driving. For 2026, the business rate opened at 72.5¢ per mile and rose to 76¢ per mile from July 1 after a rare mid-year adjustment driven by fuel costs — see our full breakdown of the 2026 rate change.
This calculator applies the correct half-year rate automatically based on your trip date, and totals multiple legs — office to client, client to client, client back to office — leg by leg rather than as a single straight-line distance, which is how the IRS expects mileage to be logged and reimbursed.
Reimbursing at or below the IRS rate under an accountable plan keeps the payment tax-free to the employee; our guide to IRS mileage reimbursement rules for employers covers the compliance side in full.
