Mileage Reimbursement Calculator

Work out what you are owed for driving your own car for work, volunteering or medical trips. Enter one trip or a whole list of trips, double them for round trips, repeat a regular route, add tolls and parking, and multiply by your employer’s rate or the IRS standard mileage rate — in miles or kilometers.

Quick examples

One trip, or several separated by commas: 12, 8.5, 30.

times

For a repeated route, e.g. 4 for a weekly client visit over a month.

      Formula

      Total distance = sum of trips × 2 for round trips × number of times driven
      Mileage amount = total distance × rate per mile (or per km)
      Reimbursement = mileage amount + tolls and parking
      Average per trip = reimbursement ÷ number of trips

      How to use it

      1. Enter a trip distance, or several separated by commas.
      2. Choose miles or kilometers, and turn on doubling if the distances are one way.
      3. Enter how many times the trips were driven and the rate per mile or km.
      4. Add tolls and parking, and read the reimbursement and the trip-by-trip table.

      IRS standard mileage rates

      For 2025 the IRS rates are 70 cents a mile for business, 21 cents for medical travel and for moving by active-duty members of the Armed Forces, and 14 cents for driving in service of a charity, a figure set by law rather than by the IRS. For 2024 they were 67, 21 and 14 cents. The IRS normally announces the next year’s rates in December, so check irs.gov for the year you are claiming.

      The business rate is meant to cover fuel, maintenance, insurance, depreciation and other costs of running the car. Tolls and parking for business trips are claimed on top of it.

      Who has to reimburse mileage

      US federal law does not make employers reimburse mileage unless unreimbursed costs would push an employee’s pay below the minimum wage. Some states go further: California and Illinois, for example, require employers to reimburse necessary business expenses, which includes driving for work. Many employers simply use the IRS rate; any rate is allowed.

      Reimbursement under an accountable plan — at or below the IRS rate and backed by a mileage log — is not taxable wages. Since 2018 most employees cannot deduct unreimbursed mileage on their federal return, while self-employed people deduct business miles as a business expense.

      Keeping a mileage log

      Record each trip when you make it: the date, where you went, the business purpose and the miles, from the odometer or a map. Driving from home to your regular workplace is commuting and does not count as business mileage; driving from the office to a client does. In the UK, HMRC’s approved mileage allowance for cars and vans is 45p a mile for the first 10,000 business miles in a tax year and 25p after that.

      Questions people ask

      How do I calculate mileage reimbursement?

      Multiply the miles driven by the rate. At the 2025 IRS business rate, 120 miles × $0.70 = $84. Add tolls and parking on top.

      What is the IRS mileage rate for 2025?

      70 cents per mile for business use, 21 cents for medical and qualifying military moves, and 14 cents for charitable driving.

      Is mileage reimbursement taxable?

      Not when it is paid under an accountable plan at or below the IRS rate and supported by records. Amounts above the IRS rate, or flat car allowances paid without a log, are taxable wages.

      How much is 500 miles of reimbursement?

      $350 at the 2025 IRS business rate of 70 cents a mile, or $335 at the 2024 rate of 67 cents.
