Mileage Reimbursement Calculator

The Mileage Reimbursement Calculator turns the miles you drive into the money you are owed, using the official IRS standard mileage rates. Instead of working out a single trip, you can log multiple trips at once — each with its own purpose and one-way or round-trip distance — and get a combined total with a clear breakdown by category. It is built for employees claiming travel expenses, the self-employed tracking business miles, volunteers logging charitable driving, and active-duty military members claiming moving mileage.

What Is Mileage Reimbursement?

Mileage reimbursement is money paid to cover the cost of using your personal vehicle for an approved purpose — such as business travel, medical visits, charitable work, or a military move. Rather than tracking fuel, insurance, depreciation, and maintenance separately, most reimbursements use a single per-mile rate that bundles all of those costs together. The IRS publishes a "standard mileage rate" each year that employers and taxpayers can use as a simple, accepted benchmark.

Mileage Reimbursement Formula

The core calculation is simple: multiply the distance you drove by the rate that applies to that type of driving. When you have several trips, you total each one up.

Because business, medical, charity, and moving miles can each carry a different rate, this calculator applies the correct rate to every trip and then adds them together for your combined total.

IRS Standard Mileage Rates by Year

The table below shows the IRS standard mileage rates (in US dollars per mile) used by this calculator. Rates are set by the IRS each year; the charitable rate is fixed by law and rarely changes. Always confirm the current figures on IRS.gov before filing.

*The moving rate applies only to active-duty members of the Armed Forces moving under orders. The 2026 row carries the 2025 rates forward as a provisional default and should be verified once the IRS publishes its 2026 notice.

Tips for Accurate Mileage Claims

• Keep a contemporaneous log: Record the date, purpose, start and end points, and miles for each trip as it happens. The IRS expects reliable records.
• Use actual distances: Reimburse the real distance driven, including round trips, not estimates.
• Separate commuting: Your regular commute between home and your main workplace is generally not reimbursable business mileage.
• Match the right rate: Business, medical, charity, and moving miles use different rates — don't apply the business rate to everything.

Frequently Asked Questions

How do I calculate mileage reimbursement?

Multiply the number of miles you drove by the applicable IRS standard mileage rate. For example, 100 business miles in 2025 at 70 cents per mile equals 70 dollars. If you have several trips, calculate each one and add them together for a combined total.

What are the 2025 IRS standard mileage rates?

For 2025 the IRS standard mileage rates are 70 cents per mile for business, 21 cents per mile for medical and active-duty military moving, and 14 cents per mile for charitable driving. Always confirm the current rates on IRS.gov, as they are updated each year.

Are business and medical mileage reimbursed at the same rate?

No. The IRS sets a higher rate for business driving than for medical or moving driving, and a separate, lower statutory rate for charitable driving. This calculator applies the correct rate to each trip based on the purpose you select.

Can I claim moving mileage?

Since the Tax Cuts and Jobs Act, the moving expense deduction and its mileage rate apply only to active-duty members of the Armed Forces who move under military orders. Most other taxpayers cannot deduct moving mileage.

Is mileage reimbursement taxable?

Reimbursement paid at or below the IRS standard mileage rate under an accountable plan is generally not taxable income. Amounts paid above the standard rate, or payments without proper documentation, may be treated as taxable wages.

Do I use one-way or round-trip miles?

Reimburse the actual distance you drove. If you drove to a destination and back, use the full round-trip distance. This calculator has a round-trip toggle that doubles the one-way distance for you.
