Mileage Reimbursement Calculator

What the mileage reimbursement calculator does

If you drive your own car for work, medical trips, or volunteering, you can often claim a set amount per mile, and this tool adds it up. You choose the tax year, which fills in the official rates, then enter your miles for business, medical, and charitable driving, and it gives you the reimbursement for each category and the total. It uses the standard mileage rates set for each year, so the figure follows the official per-mile amounts rather than a guess.

It is the simple way to turn a mileage log into a dollar figure, without tracking every receipt for fuel and repairs.

What the standard mileage rate covers

The standard mileage rate is a single per-mile figure meant to cover the whole cost of running a car for that mile, not just the fuel. Folded into it are the running costs like gas, oil, maintenance, tires, and insurance, and for business miles, a share of the car's depreciation too. That is the appeal of it: instead of saving every receipt and working out what proportion of your real costs counts, you multiply your miles by one rate and you are done. It is an optional method, the alternative being to track your actual expenses, but for most people the standard rate is far simpler.

How to use it

1. Tax Year. Pick the year, and the business, medical, and charitable rates fill in automatically.
2. Miles for Business. Miles driven for business purposes that year.
3. Miles for Medical. Miles driven for qualifying medical or moving purposes.
4. Miles for Charity. Miles driven in service of a qualifying charitable organisation.

Why the three rates differ

The three categories are paid at different rates, and the reasons are worth knowing. The business rate is the highest, because it is based on a yearly study of the full cost of running a car, including depreciation, so it tracks what driving actually costs and changes from year to year. The medical and moving rate is lower, because it is based only on the running costs, leaving depreciation out. And the charitable rate is the odd one out: it is fixed in law rather than tied to costs, which is why it has stayed at 14 cents a mile for years while the others move. So if business miles are worth far more per mile than charity miles in the result, that difference is built into the rules, not a quirk of the tool.

An example with real numbers

Using the 2026 rates, say you drove 5,000 miles for business, 500 for medical trips, and 200 for a charity.

• Business: 5,000 miles at 72.5 cents = 3,625
• Medical: 500 miles at 20.5 cents = 102.50
• Charity: 200 miles at 14 cents = 28
• Total reimbursement = about 3,755

So those miles add up to roughly 3,755 for the year. The business miles do most of the lifting, both because there are more of them and because they are paid at the highest rate, which is usually how the total breaks down.

The rates change every year

One thing to keep the figure accurate: the standard mileage rates are reset each year, so the year you choose matters. This tool includes every tax year from 2015 through 2026, with the mid-year change in 2022 split into its two periods. For 2026 the business rate is 72.5 cents, up from 70 cents in 2025 and 67 cents in 2024, while the charitable rate has stayed at 14 cents the whole time because it is fixed by law. The IRS publishes new figures each year, so for any year after 2026, use the official current rate before you rely on a number for a filing.

Worth knowing before you claim

A few honest points, since this touches your taxes. The rules on who can claim each category have conditions. Unreimbursed employee travel is generally no longer deductible for most employees under current law, so the business rate is mainly useful to the self-employed or for employer reimbursements. The moving rate is limited to certain active-duty members of the Armed Forces. Medical mileage is claimed as part of itemised deductions and is subject to an income threshold. Whichever category applies, keep a proper mileage log, the dates, the purpose, and the miles, because that record is what supports the claim. This tool gives you a solid estimate of the figure, but for how the rules apply to your situation, check the IRS guidance or a tax professional.

Questions people ask

How is mileage reimbursement calculated?

You multiply your miles in each category by the standard rate for that category and year, then add them up. The standard rate is meant to cover the full per-mile cost of running the car, not just fuel.

Why is the business rate higher than the others?

The business rate is based on the full cost of running a car including depreciation, while the medical and moving rate covers running costs only. The charitable rate is fixed in law at 14 cents, separate from costs.

What is the current mileage rate?

For the 2026 tax year the business rate is 72.5 cents a mile, the medical and moving rate is 20.5 cents, and the charitable rate is 14 cents. The tool includes every year back to 2015. Rates change annually, so for a year after 2026, check the IRS for the official figure.

Do I need to keep records?

Yes. Keep a mileage log with the date, purpose, and miles for each trip. That record is what supports your claim, and eligibility rules differ by category, so check the IRS guidance for your situation.
