What is a mileage reimbursement calculator?
A mileage reimbursement calculator is a free online tool that helps you calculate IRS-standard mileage reimbursement amounts for business, medical, and charitable driving. It runs entirely in your browser — no signup, no app, and no data is ever sent to a server.
A mileage reimbursement calculator is a free tool that computes exactly what you are owed for business, medical, or charitable driving using the latest IRS standard mileage rates. Enter your miles and the calculator returns your reimbursement instantly — no spreadsheet, no guessing whether you are using the correct rate for the year.
When I helped my sister calculate her reimbursement for a 200-mile weekly sales route across Ohio, the figure that surprised her most was the annual projection: at 70¢/mile, her 10,400 annual business miles were worth $7,280 — more than she expected and enough to pay for a family vacation.
How it works
The math is straightforward: miles driven multiplied by the applicable IRS rate. For 2025 and 2026, the business rate is 70 cents per mile. Drive 400 business miles in a month and your employer owes you $280. Drive 400 miles per week and your annual reimbursement works out to $14,560. The IRS sets three separate rates for a reason: the business rate (70¢) accounts for the full cost of vehicle ownership — fuel, depreciation, insurance, maintenance, and registration. The medical rate (21¢) covers only the variable costs. The charitable rate (14¢) has not moved since 1998 because Congress controls it, not the IRS.
I find that most people only track their business miles, which is fine for most scenarios. But if you volunteer driving for a charity or take family members to medical appointments, the All Categories tab on this calculator gives you a single screen to capture all three categories at once, complete with a color-coded bar chart showing where your miles are going.
IRS mileage rate history
The rate has climbed from 56¢ in 2021 to 70¢ in 2025 — a 25% increase over four years. The 2022 mid-year adjustment from 58.5¢ to 62.5¢ was only the third mid-year change in IRS history; gas prices surged past $5 a gallon nationally and the IRS had to respond. For 2026, the rate holds steady at 70¢, which is only the second time in a decade the rate stayed flat year over year (the first was 2019–2020 at 57.5¢).
What annoys me is that most competing mileage calculators still display the 2023 or 2024 rate by default. If you are submitting a reimbursement request to your employer or deducting mileage on your taxes, always verify you are using the current figure — this calculator defaults to 70¢ for 2025–2026.
Common mistakes people make with mileage reimbursement
Tracking commute miles as business miles. This is the single biggest error I see. The IRS defines commuting — driving from home to your regular workplace — as personal, not business, even if the drive is 90 minutes each way. Business miles are driving between two job sites, visiting a client, or going to a temporary work location. A real estate agent driving from their home to three open houses is doing business driving. An accountant driving from home to the same office every morning is commuting.
Not keeping a contemporaneous log. The IRS does not accept a spreadsheet you built at the end of the year when you are already under audit. You need records created at or near the time of each trip showing date, destination, business purpose, and miles. I recommend a mileage app that auto-logs your trips — the annual subscription is far cheaper than the deduction you lose if the IRS disallows your claim. Without a proper log, even legitimate business mileage becomes an audit risk.
Using the wrong year's rate. The 2024 rate was 67¢/mile. If you are filing a 2025 tax return or submitting a 2026 reimbursement request, 67¢ is wrong. The calculator defaults correctly, but if you are editing the rate field manually, double-check which year your expense applies to.
Business vs personal mileage
The dividing line is clearer than most people think. Driving between two work locations — yes. Visiting a client — yes. Traveling to a temporary work site that is not your regular office — yes. Your daily home-to-office commute — never. Even if you stop at a coffee shop en route or run a business errand on the way home, the IRS allows the business portion only if the trip has a bona fide business purpose as its primary reason. A mileage reimbursement calculator helps you quantify each trip's value so you can decide whether tracking it is worth the effort.

Frequently asked questions
What is the IRS mileage rate for 2026?
The IRS business mileage rate for 2026 is 70 cents per mile ($0.70/mile), the same as 2025. The IRS typically announces the new rate in December of the prior year. The medical and moving rate (active military only) is 21 cents per mile, and the charitable rate remains at 14 cents per mile — set by statute and unchanged since 1998.
How do I calculate mileage reimbursement for work?
Multiply your total business miles driven by the IRS standard mileage rate. For 2025–2026, that is $0.70 per mile. If you drove 350 business miles, your reimbursement is 350 × $0.70 = $245.00. Keep a mileage log with dates, destinations, and business purpose — the IRS requires documentation if your deduction is ever audited.
Is mileage reimbursement taxable income?
Employer mileage reimbursements paid at or below the IRS standard rate are not taxable income, provided you submit an adequate mileage log. Amounts reimbursed above the standard rate are treated as taxable wages. If your employer does not reimburse you, you can deduct business mileage on Schedule C (self-employed) or as an unreimbursed employee expense if eligible.
What is the difference between business and medical mileage rates?
Business mileage (70¢/mile for 2026) compensates for fuel, depreciation, insurance, and maintenance — the full cost of operating a vehicle. The medical rate (21¢/mile) only covers variable costs like fuel and oil. Charitable mileage (14¢/mile) is the lowest and is fixed by Congress, not the IRS, which is why it has not changed since 1998 despite inflation.
Can I deduct more than the standard mileage rate?
You can use the actual expense method instead of the standard rate, deducting real costs: fuel, oil, tires, repairs, insurance, registration, and depreciation. This sometimes yields a higher deduction for high-cost vehicles or heavy drivers. However, you must choose between standard mileage and actual expenses in the first year; switching between methods later has restrictions. Most people find the standard rate simpler and comparable.
How does commuting affect mileage reimbursement?
Commuting from home to your regular workplace is never deductible or reimbursable under IRS rules, even if the commute is long. Only business driving between work locations, to client sites, or to temporary assignments counts. I see people make this mistake constantly — they track every mile their car moves and expect reimbursement, then get surprised when their employer rejects the home-to-office leg.
