Purpose

About the Mileage Calculator

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

How the Mileage Calculator works

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 the Mileage Calculator

  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 for the Mileage Calculator

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

Formula used by the Mileage Calculator

Reimbursement = Miles Driven × Rate per Mile

Example: Mileage Calculator

500 business miles at an illustrative 67¢/mile custom rate

  • Miles driven: 500
  • Purpose: Business
  • Year: Custom Rate
  • Custom rate: 67 ¢/mi (illustrative — check the current IRS rate)

Result: Reimbursement $335.00

500 miles × 67¢ ÷ 100 = $335.00. Always confirm the current-year IRS standard mileage rate (selectable directly by year in this tool), since it changes annually.
