About the Mileage Reimbursement Calculator
This mileage reimbursement calculator works out how much you should be paid back — or can deduct — for driving your own vehicle for work, medical appointments or charity. Enter the one-way distance, whether you drove there and back, and how many trips you made, then pick the purpose and rate period. The calculator applies the matching IRS standard mileage rate, or a custom rate if your employer uses its own.
2026 has two sets of IRS rates. For miles driven January 1 to June 30, 2026 the business rate is 72.5 cents per mile and the medical and military-moving rate is 20.5 cents. Because of higher fuel prices, the IRS raised them for miles driven on or after July 1, 2026 to 76 cents for business and 23.5 cents for medical and moving. The charitable rate stays at 14 cents all year because it is set by statute. If your trips span both halves of 2026, run the calculator once for each period and add the results. The 2025 and 2024 rates are included for back-dated claims. Tolls and parking for business trips are reimbursable and deductible on top of the per-mile amount, so you can add them separately.
Employees use this to fill in expense reports, and self-employed people and small-business owners use it to estimate the vehicle deduction on Schedule C. Commuting between home and a regular workplace does not count as business mileage. Keep a contemporaneous log of dates, destinations, purpose and miles to support any claim.
With the default inputs, the total reimbursement is $729.60. Change any value above to recalculate instantly.
How to use the mileage reimbursement calculator
- 1Enter the one-way distance of a typical trip.
- 2Turn round trip on if you drove there and back, and enter the number of trips.
- 3Choose the purpose and the period the miles were driven in, or a custom employer rate.
- 4Add any business tolls and parking fees.
- 5Use the total on your expense report or tax records.
Formula and method
Total miles is the one-way distance, doubled for a round trip, multiplied by the number of trips. That mileage is multiplied by the rate per mile — the IRS standard mileage rate for the chosen period and purpose, or your employer’s custom rate — and tolls and parking are added at cost.
The IRS standard rate is designed to cover all the costs of operating a vehicle, including fuel, maintenance, insurance and depreciation, so you cannot also claim those separately when you use it. Business tolls and parking are the exception and are added on top.

Worked examples
20 round trips of 24 miles at the July–December 2026 business rate
24 miles each way is 48 miles per trip, and 20 trips is 960 miles. At the 76¢ rate for miles driven from July 1, 2026 the reimbursement is $729.60.
The same trips driven in the first half of 2026
Before July 1, 2026 the business rate was 72.5¢, so the same 960 miles are worth $696, which is $33.60 less than at the second-half rate.
One-way 150-mile trip in 2025 with tolls
At the 2025 business rate of 70¢, 150 miles is worth $105. Adding $18.50 of tolls brings the total to $123.50.
Medical appointments from July 2026
Ten round trips of 12 miles each way is 240 miles. At the medical rate of 23.5¢ for miles driven from July 1, 2026 that is $56.40 toward your medical expense deduction.
Employer pays 58¢ per mile
15 round trips of 35 miles each way is 1,050 miles. At 58¢ that is $609, plus $40 of parking for a $649 claim.
Frequently asked questions
What is the IRS mileage rate for 2026?+
For miles driven January 1 to June 30, 2026 the IRS rate is 72.5 cents per mile for business and 20.5 cents for medical care and qualifying military moves. From July 1, 2026 the IRS raised these to 76 cents and 23.5 cents because of fuel prices. The charitable rate is 14 cents all year.
Why are there two IRS mileage rates in 2026?+
The IRS usually sets the rates once a year, but it can revise them mid-year when fuel costs change sharply. Announcement 2026-11 raised the business and medical/moving rates for miles driven on or after July 1, 2026, as it did in mid-2022. Use the rate that applies to the date of each trip.
Is mileage reimbursement taxable?+
Reimbursement under an accountable plan at or below the IRS standard rate, backed by a mileage log, is not taxable income for employees. Amounts paid above the IRS rate, or flat car allowances without substantiation, are generally treated as taxable wages.
Can I deduct mileage as an employee?+
Under current federal law, unreimbursed employee business expenses, including mileage, are not deductible for most W-2 employees. Self-employed people, some reservists, performing artists and fee-basis officials can still deduct business mileage.
Does commuting count as business mileage?+
No. Driving between your home and your regular place of work is personal commuting, even if you take work calls on the way. Trips from your workplace to clients, between job sites or to temporary work locations usually do count.
What records do I need for a mileage claim?+
Keep a log showing the date, starting point and destination, business purpose and miles for each trip, recorded at or near the time of the trip. Save receipts for tolls and parking. Apps and odometer photos can help make the log reliable.
