Expense Reimbursement Calculator
Enter your miles, mileage rate, and out-of-pocket costs.

How it is calculated
The claim is built from two parts. Mileage is miles × rate per mile. The other part is simply meals + lodging + other. The total is the sum of both, and the tool shows all three figures in dollars. Miles is the only required field. If you leave the rate empty, 0.76 per mile is used (the IRS business standard mileage rate from 1 July 2026), and empty meals, lodging or other fields count as zero. Negative numbers are not accepted. The tool adds what you enter: it does not apply per-diem limits, receipt rules or caps, and the right mileage rate depends on your employer and country, so check the current policy before filing.
Worked example
A 240-mile business trip at 0.67 per mile gives mileage of 240 × 0.67 = $160.80. Meals of $85.50, a hotel at $189 and $24.75 of parking and tolls add up to 85.50 + 189 + 24.75 = $299.25 of non-mileage costs. The total claim is 160.80 + 299.25 = $460.05.
Common mistakes
- Entering kilometres in the miles box while using a per-mile rate. Either convert the distance or enter a per-kilometre rate with kilometres, never mix them.
- Typing the rate in cents (67) instead of dollars (0.67), which inflates the mileage amount a hundredfold.
- Leaving miles empty on a trip with only hotel and meal costs. Miles is required, so enter 0 to get a total.
- Putting fuel receipts in "other" as well as claiming mileage. A mileage rate normally already covers fuel, so this counts the same cost twice.
- Using the default 0.76 without checking it. It is only a starting value, and employers and tax authorities set their own rates each year.

About this calculator
Business travel typically involves several categories of out-of-pocket spending — driving your own car, meals, hotel stays, parking, and other incidentals — that an employer reimburses after the trip. Mileage is usually reimbursed at a standard per-mile (or per-kilometer) rate set by the company or, in the U.S., the IRS standard mileage rate, rather than actual fuel cost.
This calculator totals a reimbursement claim by combining mileage (miles driven × rate) with meals, lodging, and other logged expenses. It's used by employees filing expense reports and the finance or HR staff who process them, giving a quick check on what a trip should cost to reimburse before receipts and mileage logs are formally submitted.

Use the three outputs to test a claim against your travel policy before filing. A two-night trip with no driving, 60 in meals and 150 in lodging comes to 210.00 with mileage at zero; enter 0 in the miles box to get that. Keeping the mileage figure apart from the receipt-backed costs also makes the claim easier for finance to audit. Which expense category would you like to see split out further?
