Mileage Calculator

What this calculator does

The Mileage Calculator turns a distance and a rate into a total mileage figure and a reimbursement amount. It is useful for business travel logs, moving expenses, volunteer driving, and any situation where a trip is reimbursed at a fixed rate per mile or per kilometer.

The calculator has two modes. Reimbursement mode applies a rate to a single distance. Trip mode multiplies a one-way distance by the number of trips and optionally doubles it for a round trip. A rate is required in reimbursement mode and optional in trip mode, so you can use trip mode purely as a distance calculator.

This page does not look up routes or calculate directions. Enter the distance from your odometer, a map, or an official trip log.

How to use this calculator

1. Choose mileage reimbursement or trip mileage.
2. Enter the distance and choose miles or kilometers.
3. In trip mode, enter the number of trips and choose one way or round trip.
4. Enter the rate and choose per mile or per kilometer. The rate is optional in trip mode.
5. Click Calculate.

If the distance and rate use different units, the calculator converts them automatically. For example, a per-kilometer rate can be applied to a distance entered in miles.

Formula

Reimbursement mode:
Total distance = distance
Reimbursement = distance x rate

Trip mode:
Total distance = one-way distance x number of trips x (2 for round trip)
Reimbursement = total distance x rate

Unit conversion: 1 mile = 1.609344 kilometers

The rate per mile and the rate per kilometer are both shown in the result, along with the total distance in both units. A rate of $0.67 per mile is about $0.4163 per kilometer.

Default example

The default reimbursement example uses 120 miles at $0.67 per mile. The reimbursement is $80.40, and the distance is about 193.12 kilometers.

The default trip example uses a one-way distance of 12 miles, 2 trips, and a round trip. The total distance is 12 x 2 x 2 = 48 miles. At $0.67 per mile, the reimbursement is $32.16.

Assumptions and limitations

• The entered distance is taken as accurate. The calculator does not measure a route or correct for detours.
• The rate is flat for the entire distance. Tolls, parking, ferries, and meals are not added unless they are built into the rate.
• A round trip doubles the one-way distance. Multi-stop trips should be entered as the total distance or split into separate calculations.
• The calculator does not decide whether an expense is tax-deductible. Tax rules and approved rates change and depend on the purpose of the travel.
• Results are rounded for display; the internal calculation keeps more precision.

Frequently asked questions

Can I use this for IRS mileage reimbursement?

You can apply any rate you choose, including a standard mileage rate. However, the calculator does not determine whether your trip qualifies or which rate applies. Check the current IRS guidance or ask a tax professional before filing.

Does this calculator find the distance between two addresses?

No. It works from a distance you provide. Use a mapping service or your odometer to get the one-way distance, then enter that number here.

How should I handle a trip with several stops?

Add the distances between stops to get the total one-way distance, then enter that total. If every leg is a round trip, you can also calculate each leg separately and add the reimbursements.
