How mileage reimbursement is calculated
Multiply documented business miles by the rate that applies to the trip, then add separately reimbursable parking, tolls and approved expenses.
Reimbursement = business miles × rate + parking + tolls + other expenses
Use the rate from your policy
This calculator intentionally does not hard-code a government, employer or platform rate. Enter the rate and expense rules that apply to the relevant date and organization.
Keep a mileage log
Record the date, business purpose, origin, destination and miles for every trip. Commuting and reimbursable business travel may be treated differently, so follow the policy responsible for approving the claim.
