Calculate business mileage reimbursement or tax deduction from miles driven and a per-mile rate.
Enter miles driven and rate, then click Calculate
This free mileage calculator computes business mileage reimbursement or tax deduction amounts by multiplying miles driven by a per-mile rate — the same simple math used for employer reimbursement and the IRS standard mileage deduction method.
Enter your total business miles driven and a rate per mile — either your employer's reimbursement policy rate or the current-year standard mileage rate — and the calculator multiplies the two to give your total reimbursement or deduction amount. Because standard mileage rates change annually (and occasionally mid-year), the rate field is fully editable so the tool stays accurate no matter what year you're calculating for.
Self-employed workers and freelancers claiming the standard mileage deduction, employees seeking reimbursement for business driving, small business owners tracking vehicle costs, and gig workers (rideshare, delivery) estimating their mileage-based tax deduction.
The simple multiplication behind the standard mileage method
A single per-mile rate covers gas, maintenance, depreciation, and insurance combined — no need to track each expense separately.
Standard mileage rates are updated each year (and occasionally mid-year) to reflect current fuel and vehicle ownership costs.
A defensible reimbursement or deduction claim needs a log of dates, destinations, and business purpose — not just a total mile count.
From miles driven to reimbursement total
Type the total business miles driven for the period you're calculating.
