What this calculator is solving
The Mileage Calculator estimates a mileage amount from miles and a rate per mile. It can also add parking, tolls, or other trip costs when those extras belong in the same claim.
Match each input label on the calculator to the miles driven, the allowed rate per mile, and any extras that belong in the same trip total.
The formula in plain language
In plain language: Mileage amount = miles driven x rate per mile. Total = mileage amount + parking, tolls, or other entered extras. The examples on the page are there so you can compare your inputs with a reimbursement example before copying the answer.
The calculator multiplies miles by the rate per mile. Then it adds parking, tolls, or extras you enter separately.
How to read the answer
Read mileage only as the miles-by-rate amount. Read total as mileage only plus extras, so it is the number you would copy into a draft invoice or reimbursement note.
- 125 miles at $0.725 per mile gives $90.63 before extras.
- Adding $12 in parking or tolls gives $102.63 total.
- The rate is repeated so you can check the assumption before copying the answer.
Common mistakes to avoid
The main mistake is treating an example rate as official. For 2026, the IRS business rate and the GSA rate for an authorized privately owned car are both $0.725 per mile, but your own rule can still be different.
- Do not assume the default example rate is the rate you should use.
- Use your employer, client, tax authority, or contract rule first.
- Keep documentation if the mileage is for reimbursement or taxes.
- Do not add parking or tolls twice if your system already handles them somewhere else.
Example: 125 miles at the 2026 business rate
Say a client visit is 125 miles and your allowed rate is $0.725 per mile. The mileage-only amount is 125 x 0.725, which is $90.625.
Money normally rounds to cents, so that becomes $90.63. If the trip also has $12 in approved extras, the total is $102.63.
Why the rate matters more than the math
The IRS 2026 business standard mileage rate is 72.5 cents per mile. GSA also lists $0.725 per mile for an authorized privately owned automobile in 2026.
That does not mean every claim should use $0.725. Some employers, delivery apps, contracts, charities, medical trips, and military moving claims can use different rates.
What to keep with the result
Keep the date, trip purpose, start and end points or odometer notes, miles, rate source, and receipts for extras. A calculator total is useful, but proof is what makes a claim easier to defend.
If you are using this for taxes, treat the calculator as arithmetic only. It does not decide whether the trip is deductible.

FAQ in plain language
When should I use the Mileage Calculator?
Use it when your task matches one of these common needs: Estimate mileage reimbursement from miles and rate. Add parking, tolls, or trip extras. It works best when you already know the miles driven, the rate per mile, and any parking, tolls, or extras that should be added.
What is the Mileage Calculator doing with my inputs?
In plain language: Mileage amount = miles driven x rate per mile. Total = mileage amount + parking, tolls, or other entered extras. The examples on the page are there so you can compare your inputs with a reimbursement example before copying the answer.
What do the main Mileage Calculator inputs mean?
Miles: the trip distance you are claiming or checking. Rate per mile: the allowed dollar amount for each mile, such as 0.725 for 72.5 cents per mile. Extras: parking, tolls, or other trip costs you are allowed to add separately. Mileage only: miles multiplied by the rate, before extras. Total: mileage only plus the extras you entered.
How should I read the Mileage Calculator answer?
Read the headline answer, then check the smaller lines beside it. For everyday tools, those lines usually show the distance, time, cost, units, or setting that made the answer change.
What should I double-check before trusting the answer?
The 2026 IRS business rate and the GSA rate for an authorized privately owned car are both $0.725 per mile, but your employer, client, contract, app, or tax situation may use a different rule. Check the rate source, the trip date, and whether parking or tolls should be added separately. Do not assume the example rate applies to every job or tax return.
What is the 2026 IRS business mileage rate?
The IRS announced 72.5 cents per mile for business use starting January 1, 2026. That is $0.725 in this calculator. It is optional for tax use, so check the rule that applies to your trip.
Is the GSA 2026 privately owned car rate also 72.5 cents?
Yes. GSA lists $0.725 per mile from January 1, 2026 when a privately owned automobile is authorized or no government-furnished automobile is available.
