Mileage Reimbursement Calculator

The Mileage Reimbursement Calculator is a simple budgeting and accounting utility. It calculates the reimbursement sum when driving a personal vehicle for work, business, medical travel, or charity services. Many companies pay a flat rate per mile to cover fuel, wear and tear, and insurance expenses.

1. Enter the distance driven for the claim. Use miles for IRS rates, kilometres for HMRC or CRA rates.
2. Enter the rate per unit, or tap one of the IRS preset buttons above.
3. Press Calculate Reimbursement to see the total, along with the distance and rate applied.

Keep the number you claim tied to a contemporaneous log. Tax authorities generally expect the date, purpose, start and end points, and mileage for each trip — reconstructed estimates are the most common reason a mileage deduction is disallowed.

The IRS revised its 2026 rates mid-year, citing fuel price increases, so which rate applies depends on when you drove:

^* The moving expense rate applies only to qualified active-duty members of the Armed Forces. The charitable rate is fixed by statute rather than set annually by the IRS, which is why it has not moved.

If your trips straddle 1 July, split the log at that date and run this calculator twice — once at each rate — then add the results.

Rates Outside the United States

Other jurisdictions publish their own approved rates, and several taper the rate after a mileage threshold:

• United Kingdom (HMRC approved mileage allowance payments): 45p per mile for the first 10,000 business miles in a tax year, then 25p per mile beyond that, for cars and vans.
• Canada (CRA): a per-kilometre rate for the first 5,000 km, then a lower rate above that, with a supplement for the territories.
• European Union: no single rate — each member state sets its own, and many employers use a published national scale.

Because rates change and thresholds differ, this calculator takes any rate you type rather than assuming a jurisdiction. Always confirm the current published figure with your own tax authority before filing.

Standard Rate or Actual Expenses?

The standard mileage rate is designed to cover all vehicle operating costs: fuel, depreciation, insurance, maintenance, repairs, oil, and tyres. You cannot claim the standard rate and then also deduct fuel — that would double-count. Parking fees and tolls incurred on business travel are the usual exception and can be claimed on top.

The alternative is the actual expense method: track every vehicle cost for the year and deduct the business-use percentage. That tends to win for expensive vehicles, low annual mileage, or heavy commercial use, and the standard rate tends to win for ordinary cars driven a lot. If you want to see what your fuel alone actually costs per mile, so you can judge whether the standard rate is generous or stingy for your vehicle, run the fuel cost calculator or the trip cost calculator.
