How to calculate mileage reimbursement manually

If you wish to calculate mileage reimbursement manually, you can do so easily by following the instructions.

Let’s say you drive your car for both business and private purposes and keep a mileage log so that you can see exactly how many miles you have driven for business. Your records show that you drove 7000 miles for business from January 2025 until the end of May.

To calculate your total reimbursement, you would need to multiply the miles you have driven by the appropriate IRS mileage rate for 2025. Your calculation would look like this:

7000 x 0.70 = $4,690 (business reimbursement)

To get that reimbursement, you need to make sure that you have logged everything in your mileage log and that you can provide proof if necessary.

Make sure your mileage logs are IRS-compliant

The easiest way to ensure your mileage logs are compliant is to use a mileage tracker app such as Driversnote. The app always keeps you up-to-date on mileage rates, and you can upload older trips to find your reimbursement. You can add trips either manually or use automatic mileage tracking to ensure you never miss a trip.

Remember that you need to log not only your business, medical, charity, and moving mileage but also your personal miles if you use the vehicle for personal trips. 

• Can I calculate my fuel costs with this mileage calculator?
