Mileage Calculator

Calculate distance traveled from odometer readings or a trip distance, with optional reimbursement from your own rate.

Your vehicle and journey inputs

Prefilled measurements are editable examples. Prices and rates start at zero: unpriced, not local quotes. All fields are required unless marked optional. Results clear when inputs change. Unit changes convert current values; currency changes preserve numbers without exchange rates.

Currency labels only. Enter all prices and expenses in the selected currency. No exchange-rate conversion.

Enter readings or distance for the selected method. Newly shown fields start with editable examples.

Reading at the start of the journey.

Must be at least the starting reading.

Distance and reimbursement

Review the editable example values, enter your own prices where needed, then calculate.

How do I calculate mileage and optional reimbursement?

Distance traveled = ending odometer − starting odometer, or the entered trip distance. Reimbursement = distance converted into the rate’s unit × your rate per kilometer or mile.

Worked example

Starting at 10,000 km and ending at 10,100 km gives 100 km (about 62.1371 miles). If you choose an illustrative rate of 0.50 per km, reimbursement is 50.00. No official reimbursement rate is supplied.

Unit conversions

1 mile = 1.609344 km. 1 US gallon = 3.785411784 L. 1 imperial gallon = 4.54609 L. US MPG and imperial MPG use different gallon volumes. kW measures power; kWh measures energy.

Assumptions & limitations

  • Mileage here means distance traveled, not fuel economy or MPG. Odometer readings must use the same selected unit; the ending reading cannot be less than the starting reading.
  • Reimbursement rates depend on employer policy and local rules. Obtain the applicable rate yourself; this tool does not provide official rates or determine eligibility.
  • Reimbursement is optional. A zero rate means no amount has been priced unless you intentionally enter zero. Keep any records required by your organization.
