How the Mileage Reimbursement Calculator (IRS Rate) works
Reimbursement = business miles × rate per mile, plus parking and tolls, which are claimed separately under the IRS standard mileage method.
The IRS standard mileage rate covers fuel, wear, insurance and depreciation. Commuting between home and a regular workplace is not business mileage.
The formula
Worked example
Using the default values shown in the calculator:
| Distance (miles) | 120 |
|---|---|
| Trip type | Round trip (double the distance) |
| Number of trips | 1 |
| Rate per mile | $0.725 |
| Parking and tolls (total) | $12 |
- A 120-mile round trip is 240 miles. At 72.5¢ plus $12 parking: $186.00.
Result:
| Reimbursement | $186.00 |
|---|---|
| Total miles | 240.0 |
| In kilometres | 386.2 |
| Rate per km | $0.45 |
