2026 Mileage Reimbursement Calculator

Background.

A mileage reimbursement calculator converts miles driven into a dollar figure using the IRS's own standard mileage rates, which exist precisely so taxpayers and employers don't have to track every gallon of gas, oil change, and depreciation dollar separately. For 2026, the IRS set three rates, verified directly from IRS.gov this session: 72.5 cents per mile for business driving (up 2.5 cents from 2025's 70 cents, per IRS Notice 2026-10), 20.5 cents per mile for medical care or active-duty military moving (down half a cent from 2025), and 14 cents per mile for driving in service of a charitable organization — a rate fixed directly in the tax code and unaffected by the annual inflation adjustment that moves the other two.

This calculator asks for all three mileage categories at once rather than forcing you to pick a single purpose, because many taxpayers accumulate more than one kind of deductible or reimbursable mileage in the same year: a small-business owner driving to client meetings, the same person driving a parent to medical appointments, and a weekend spent driving supplies to a volunteer event. Enter miles for whichever categories apply — leaving the rest at zero costs nothing — and the calculator returns a per-category dollar figure plus a combined total.

The business rate is the one most people are asking about, and it is meant to substitute for the actual costs of operating a vehicle — fuel, maintenance, insurance, and depreciation — rather than requiring you to track each expense separately. Self-employed taxpayers deduct business mileage directly on Schedule C; employees generally cannot deduct unreimbursed business mileage on their own return under current law (the miscellaneous itemized deduction for unreimbursed employee expenses remains suspended), so for most W-2 employees this rate matters only as the basis an employer chooses to use when setting a reimbursement policy, not as a personal tax deduction. The medical mileage rate applies to trips primarily for, and essential to, medical care, and is combined by the IRS with the moving-expense rate because the moving expense deduction itself is currently restricted to active-duty military members relocating under military orders — this calculator follows that same combined-rate convention rather than inventing a separate number the IRS does not itself publish. The charitable rate has stayed fixed at 14 cents for years because Congress, not the IRS, sets it by statute, and Congress has not adjusted it for inflation the way the IRS adjusts the other two rates annually.

Because these are flat per-mile rates rather than reimbursement of actual costs, using them means you cannot also separately deduct gas, depreciation, or repairs for the same miles — the standard mileage rate is a full substitute, not an addition, for a taxpayer who chooses that method over tracking actual vehicle expenses. If you want to compare this flat rate against your own vehicle's true all-in cost per mile — fuel, depreciation, insurance, and maintenance combined — see Quanta's cost-per-mile calculator, which answers a related but genuinely different question about what driving actually costs you, independent of what the IRS lets you claim.

What is mileage reimbursement calculator?

The IRS standard mileage rate is a flat, per-mile dollar figure the IRS publishes annually (via an IRS Notice) that taxpayers can use instead of tracking and deducting the actual costs of operating a vehicle for business, medical, moving, or charitable purposes. Rather than saving every gas receipt, oil-change invoice, and insurance statement, a taxpayer using the standard mileage method simply multiplies qualifying miles by the applicable rate. The business rate is recalculated each year based on a study of the fixed and variable costs of operating an automobile (fuel prices, depreciation, insurance, maintenance); the medical/moving rate is recalculated based primarily on variable costs; and the charitable rate is set by Congress directly in the Internal Revenue Code and has not moved with inflation the way the other two do.

Using the standard mileage rate means a taxpayer forgoes deducting actual vehicle expenses for those same miles — the two methods are alternatives to each other, not additive. Employers who reimburse employees at or below the IRS business rate can generally do so without the reimbursement being treated as taxable wages to the employee, which is why many companies simply adopt the published IRS rate as their internal reimbursement policy rather than negotiating a separate number.

How to use this calculator.

1. 01Enter your business miles for the year, if any — the 2026 rate is 72.5 cents per mile.
2. 02Enter your medical or active-duty military moving miles, if any — the 2026 rate is 20.5 cents per mile.
3. 03Enter your charitable service miles, if any — the fixed statutory rate is 14 cents per mile.
4. 04Leave any category at zero if it doesn't apply to you.
5. 05Read your per-category reimbursement amounts and the combined total.
6. 06Remember that using the standard mileage rate for a given set of miles means you cannot also deduct actual gas, maintenance, or depreciation costs for those same miles.

The formula.

Reviewed on 2026-07-27 against the IRS's own 2026 rate announcement. The calculator multiplies each mileage category by its own fixed 2026 rate and adds the three products together: business miles times 72.5 cents, medical or active-duty military moving miles times 20.5 cents, and charitable service miles times 14 cents. There is no rounding, tiering, or phase-out involved — these are flat linear rates, unlike the marginal-bracket calculations used elsewhere on this site for income tax.

The business and medical/moving rates are recalculated by the IRS every year (via an IRS Notice, typically published in December for the following tax year) based on a study of vehicle operating costs; for 2026, published in IRS Notice 2026-10, the business rate rose 2.5 cents to 72.5 cents while the medical/moving rate fell half a cent to 20.5 cents, reflecting different underlying cost components — the business rate factors in both fixed costs like depreciation and variable costs like fuel, while the medical/moving rate is based primarily on variable costs alone, which is why the two rates can move in opposite directions in the same year. The charitable rate, by contrast, is written directly into the Internal Revenue Code at a flat 14 cents per mile and only changes when Congress amends the statute — it has not moved in years and was unchanged again for 2026.
