How it works
When you drive your personal vehicle for business, charity, medical, or moving purposes, you may be reimbursed or deduct a set amount per mile, and this calculator totals it. You enter the miles driven and the rate per mile, and it returns the total reimbursement. The math is straightforward multiplication, but the rate is the important part: the IRS publishes a standard mileage rate each year that is meant to cover all the costs of operating a vehicle — fuel, oil, maintenance, repairs, tires, insurance, registration, and depreciation — so it is much more than just gas. There are different rates for business, medical or moving, and charitable driving, with the business rate being the highest. Employers often reimburse employees at the IRS business rate, and self-employed people and some employees can deduct qualifying mileage on their taxes using the standard mileage method instead of tracking actual expenses. To claim mileage, keep a contemporaneous log of dates, destinations, purposes, and miles, since documentation is required. Enter the current applicable rate for your purpose and year, as rates change annually. This calculator makes it easy to total reimbursement for an expense report, an invoice, or a tax deduction. Enter your miles and rate to find the total.
Reimbursement = miles driven × rate per mile
Mileage reimbursement is simply the number of qualifying miles driven multiplied by the reimbursement rate per mile. The standard rate, set annually by the IRS, is designed to cover fuel, maintenance, insurance, and depreciation, so it approximates the full cost of operating a vehicle per mile.

Frequently asked questions
How is mileage reimbursement calculated?
Multiply the number of qualifying miles you drove by the reimbursement rate per mile. For example, 500 business miles at 70 cents per mile is $350. The rate is meant to cover all vehicle operating costs, not just fuel, so it accounts for maintenance, insurance, and depreciation as well.
What is the IRS standard mileage rate?
The IRS sets a standard mileage rate each year for business use, with separate, lower rates for medical, moving, and charitable driving. The business rate is designed to approximate the full per-mile cost of operating a vehicle. Because it changes annually, enter the current year's rate for your purpose to get an accurate figure.
Does the rate cover more than gas?
Yes. The standard mileage rate is intended to cover the total cost of owning and operating a vehicle per mile, including fuel, oil, maintenance and repairs, tires, insurance, registration, and depreciation. That is why it is considerably higher than the cost of gas alone, and why using it can fairly compensate a driver for wear on their vehicle.
What records do I need to claim mileage?
Keep a mileage log recording the date, starting and ending locations or total miles, and the business purpose of each trip, ideally recorded at the time of travel. The IRS requires this documentation to substantiate a deduction or reimbursement. A logbook or a mileage-tracking app satisfies the requirement and protects you if your records are ever questioned.
Can I deduct mileage or must my employer reimburse it?
It depends on your situation. Employers commonly reimburse employees at the IRS business rate, which is generally not taxable income. Self-employed people can deduct qualifying business mileage using the standard mileage method. Employee deductions for unreimbursed mileage are limited under current tax law, so check the rules for your specific circumstances or consult a tax professional.
