Using the Mileage Calculator
Use the same distance unit for both readings and for the rate. If the odometer is in miles, enter a rate per mile; if it is in kilometers, use a rate per kilometer. The ending reading must be at least the starting reading.
Worked example
Use the example inputs below to reproduce this result. These are the form's starting values, not recommended targets. Changing your inputs updates your result above; this worked example stays fixed for comparison. Results are rounded for display.
Example inputs
- Starting odometer
- 10000
- Ending odometer
- 10250
- Reimbursement per distance unit
- 0.5
Example result
- Distance
- 250
- Reimbursement
- 125
Method and assumptions
Odometer difference × user-supplied reimbursement rate. Use the same distance unit throughout.
Use measurements from the same situation
Vehicle and trip estimates are easiest to compare when the inputs refer to the same journey, vehicle or operating condition. Keep the distance unit explicit and separate measured values from planning assumptions. If you change several inputs at once, record which ones changed so that a different result can be traced to a specific assumption.
Common question
Does this supply an official mileage rate?
No. The rate is user supplied and the default is only an example. Check the applicable employer policy or official source for the period and purpose of your trip before using the result in a claim.
