About Mileage Reimbursement Calculator
Mileage Reimbursement Calculator turns miles (or kilometers) driven and a per-distance rate into the reimbursement amount you should be paid or should claim. Enter the distance for a trip, the rate your employer or tax authority uses, and — if the trip mixed personal and business driving — the percent that was for business, and the calculator scopes the distance and reimbursement to that percent automatically. Switch between miles and kilometers with the unit toggle; the same distance-times-rate math applies either way. It is useful for freelancers logging deductible trips, employees submitting an expense report, or small-business owners reimbursing staff who use a personal vehicle for work. Everything runs locally in your browser — the trip details you enter are never uploaded.

Common errors & troubleshooting
- Reimbursement comes out far higher or lower than expected. — Standard mileage rates change every year and differ by country — this is an estimate, so confirm the current rate with your tax authority or employer before filing or submitting an expense report.
- Result shows an error after entering distance and rate. — Check that distance is a positive number and the rate is 0 or more — the Mileage Reimbursement Calculator needs both to compute a result.
- Reimbursement seems too low for a trip that was partly for work. — Set the business-use percent field — leaving it blank assumes the entire distance was business use, but lowering it scopes both the distance and reimbursement to only the business portion.
- Numbers look off after switching between miles and kilometers. — The rate field is per the currently selected unit, so re-enter the rate for kilometers (or miles) after switching rather than assuming it auto-converts.
Frequently asked questions
- What is the Mileage Reimbursement Calculator?
- It is a tool that multiplies the distance you drove by a per-mile or per-kilometer rate to get a reimbursement amount, with an optional split for trips that were only partly for business.
- How does the Mileage Reimbursement Calculator handle business-use percent?
- Set the business-use percent and the calculator multiplies the total distance by that percent first, then applies the rate — so only the business portion of the trip is reimbursed.
- Does the Mileage Reimbursement Calculator know the current IRS mileage rate?
- No. Standard mileage rates change every year and vary by country, so you enter the rate yourself. Check your tax authority's current published rate before using it for a tax filing.
- Can the Mileage Reimbursement Calculator work in kilometers instead of miles?
- Yes. Toggle the unit selector to kilometers, enter the distance and a per-kilometer rate, and the same distance × rate math applies.
- Does the Mileage Reimbursement Calculator upload the trip details I enter?
- No. The Mileage Reimbursement Calculator computes everything locally in your browser. The distance, rate, and business percent you enter are never uploaded to ArrayKit.
- Is the Mileage Reimbursement Calculator accurate enough for a tax filing?
- It gives a reliable estimate based on the numbers you enter, but it is not tax advice — verify the rate and your business-use percent with a tax professional before filing or submitting a claim.
