Mileage Calculator

Calculate a mileage reimbursement or tax deduction using the IRS standard mileage rates.

Purpose

About this calculator

Calculate a mileage reimbursement or tax deduction using the IRS standard mileage rates for business, medical/moving, or charitable driving.

Instead of tracking every actual vehicle expense (gas, maintenance, depreciation), the IRS lets you deduct a flat cents-per-mile rate for qualifying driving — a much simpler record-keeping method used by most self-employed people and many employers for reimbursement. The rate differs by purpose and is set annually; charitable-mileage rates are set by statute and change far less often than the business rate.

How to use

  1. Enter the number of miles driven.
  2. Select the purpose: business, medical/moving, or charitable.
  3. Select the tax year, or enter a custom rate per mile.
  4. Press Calculate to see the total reimbursement or deduction amount.

Tips

  • Keep a log of dates, miles, and business purpose for each trip — the IRS requires contemporaneous records to support a mileage deduction.

Formula

Reimbursement = Miles Driven × Rate per Mile
