Mileage Reimbursement Calculator
When you drive your own vehicle for business, you can be reimbursed using the IRS standard mileage rate, a per-mile figure meant to cover fuel, maintenance, insurance and depreciation. This calculator multiplies the miles you drove by the applicable rate to give your total reimbursement. Enter the business miles driven and the standard mileage rate, and the tool returns the amount owed. The default uses the 2024 IRS business standard mileage rate of 67 cents per mile, but the rate input is fully editable because the IRS updates it each year and some employers reimburse at a different figure. Seeing the total against the rate makes it easy to check an expense report or estimate what a trip is worth. The standard rate is an alternative to tracking actual vehicle expenses, and it is the figure the IRS publishes annually for business use. This tool computes the reimbursement only; whether it is taxable depends on your employer's accountable-plan status. Always confirm the current-year rate from the IRS. Every result here is computed deterministically from the formula shown in full below, with a worked example that reconciles exactly to the calculator so you can follow each step.
Mileage reimbursement is miles times the rate: reimbursement = miles driven times rate per mile. Driving 1,000 business miles at the $0.67 IRS rate gives a reimbursement of $670.00.
Mileage Reimbursement formula
Reimbursement = Miles driven x Rate per mile
Miles driven = business miles for the trip or period
Rate per mile = the IRS standard mileage rate (2024 business rate: 0.67)
The IRS updates the standard rate each year
The standard mileage rate bundles fuel, maintenance, insurance and depreciation into a single per-mile figure, so you only need the miles and the current rate.
Worked example
Find the reimbursement for 1,000 business miles at the 2024 IRS standard rate of 0.67 per mile.
- Multiply miles by the rate: 1,000 x 0.67 = 670.00
- Total reimbursement = 670.00
- Rate applied per mile = 0.67
These are the calculator's default inputs, so the result above matches the widget exactly.
