Mileage Reimbursement Calculator
Calculate your mileage reimbursement using the 2025 IRS standard mileage rates. Enter your miles driven and purpose to see the total reimbursement amount for business, medical, moving, or charitable driving.
The IRS sets standard mileage rates each year that you can use to calculate the deductible cost of operating a vehicle for business, medical, or charitable purposes. For 2025, the rates are:
- Business: $0.70 per mile
- Medical / Moving: $0.21 per mile (moving deduction only available for active-duty military)
- Charity: $0.14 per mile (set by statute, rarely changes)
The business rate covers gas, insurance, maintenance, depreciation, and all other vehicle operating costs. You cannot claim both the standard mileage rate and actual vehicle expenses for the same vehicle in the same year. For most people, the standard rate is simpler and often results in a larger deduction.
To claim mileage, you need to keep a log that includes the date, destination, business purpose, and miles driven for each trip. Commuting between home and your regular workplace does not qualify as business mileage. However, trips from your office to a client site, between job locations, or from a home office to a temporary work location do qualify.
The rate is updated annually based on a study of fixed and variable costs of operating a vehicle. The 2025 business rate of $0.70 is up from $0.67 in 2024, reflecting higher fuel and vehicle costs.
