Mileage Reimbursement Calculator Online
Turn miles driven and a per-mile rate into a reimbursement amount, with an optional business-use split, entirely on your device.
The Mileage Reimbursement Calculator runs entirely in your browser. The distance, rate, and business-use percent you enter are never uploaded to ArrayKit.
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.
