About Mileage Deduction Calculator
A mileage deduction calculator is a tool that multiplies the miles you drove for a deductible purpose by the IRS standard mileage rate to estimate your write-off. For tax year 2025 the rates are 70 cents per business mile, 21 cents per medical or moving mile (moving applies only to active-duty Armed Forces), and 14 cents per charitable mile, which is fixed by statute. The standard-mileage method is an alternative to deducting your actual vehicle costs, so you pick one or the other. Enter your miles by category and the tool returns each deduction and the total. It’s an estimate, not tax advice.
Use cases
- Estimate a self-employed business deduction. Freelancers, gig drivers, and small-business owners rack up deductible business miles all year. Entering your total business miles at the 2025 rate of 70 cents each turns a mileage-log number into an estimated deduction in seconds, so you can gauge the tax value of that driving before you file and plan quarterly estimated payments more accurately.
- Value charitable driving you might overlook. Miles driven in service of a qualified charity are deductible at 14 cents each if you itemize, and many volunteers never claim them. Adding up trips to deliver meals, transport supplies, or drive for an organization and multiplying by the charitable rate shows a deduction that would otherwise go unused — provided you keep a record of the trips.
- Check medical or Armed Forces moving miles. Miles driven for medical care may be deductible at 21 cents if you itemize and clear the medical-expense threshold, and the same rate covers moving miles — but only for active-duty military moving under orders. The calculator keeps these two 21-cent uses separate from business and charitable driving so you apply the right rate to the right miles.
- Compare standard mileage to actual expenses. The standard-mileage method is one of two ways to deduct vehicle costs; the other totals your actual gas, maintenance, insurance, and depreciation. This tool computes the standard-mileage figure so you have a clean number to weigh against your actual costs. Drivers with an efficient, paid-off car often come out ahead on standard mileage, while expensive vehicles may favor actual expenses.
- Plan year-end driving and logging. Seeing your mileage deduction grow as the year goes on encourages consistent logging and can inform late-year decisions, like whether to bundle deductible errands. Because the deduction is only as good as your records, using the calculator alongside a contemporaneous mileage log — date, purpose, and miles for each trip — keeps your estimate defensible if the IRS ever asks.
How it works
- Gather your mileage by purpose. From your log, total the miles you drove for each deductible category: business, medical, moving, and charitable.
- Enter business miles. Type your business miles; the tool multiplies them by the 2025 rate of 70 cents to estimate that deduction.
- Enter medical or moving miles. Add medical miles, or moving miles if you are active-duty military; both use the 21-cent rate.
- Enter charitable miles. Add miles driven for a qualified charity, which the tool multiplies by the statutory 14-cent rate.
- Read your per-category and total deduction. Each category shows its own dollar figure and they are summed into an estimated total mileage deduction for 2025.
Examples
Input: 12,000 business miles
Output: $8,400 estimated business deduction
12,000 × $0.70 = $8,400 under the 2025 standard business rate.
Input: 500 charitable miles
Output: $70 estimated charitable deduction
500 × $0.14 = $70; the charitable rate is fixed by law and only helps if you itemize.
Input: 800 medical miles
Output: $168 estimated medical deduction
800 × $0.21 = $168; deductible only if you itemize and exceed the medical-expense threshold.
Frequently asked questions
What are the 2025 IRS standard mileage rates?
For 2025 they are 70 cents per business mile, 21 cents per medical or moving mile, and 14 cents per charitable mile. The charitable rate is set by statute and does not change with inflation like the others.
Who can deduct business miles?
Self-employed people and business owners can deduct business driving. Since 2018, most W-2 employees cannot deduct unreimbursed business mileage, so this generally applies to independent workers rather than employees.
Can anyone claim the moving-mile rate?
No. Since the 2017 tax law, the moving-expense deduction — including the 21-cent moving-mile rate — is available only to active-duty members of the Armed Forces moving under military orders.
Standard mileage or actual expenses — which should I use?
It depends on your vehicle and costs. Standard mileage is simpler and often better for fuel-efficient or paid-off cars; actual expenses can win for costly vehicles. There are rules about switching methods, so check IRS guidance.
Do I need a mileage log?
Yes. The IRS expects a contemporaneous record showing the date, destination, purpose, and miles of each trip. Without one, a deduction can be disallowed if you are audited. This tool does the math but does not keep your log.
Does this compute depreciation or actual costs?
No. It only applies the standard mileage rates. It does not calculate the actual-expense method, vehicle depreciation, lease costs, or the depreciation component built into the business rate.
Is this tax advice, and is my data stored?
It is an educational estimate, not tax advice, and everything runs in your browser with nothing uploaded. Confirm eligibility and amounts with the IRS or a tax professional.
Pro tips
- Keep a contemporaneous log — date, purpose, and miles per trip — so your deduction holds up under audit.
- Don’t mix categories; business, medical, moving, and charitable miles each use a different rate.
- Commuting from home to your regular workplace is not deductible business mileage.
- Only active-duty military moving under orders can use the 21-cent moving-mile rate.
- Compare this standard-mileage estimate with your actual vehicle costs before deciding which method to claim.
