Mileage Deduction Calculator

Multiply your business miles by the IRS standard mileage rate to estimate your tax deduction — plus your business-use percentage if you add total miles. Everything runs privately in your browser.

📖 How it works & FAQ

Estimates only — not professional, financial, or tax advice. The IRS updates the standard rate annually; verify the current rate at IRS.gov.

How the mileage deduction works

The IRS lets self-employed people, freelancers, gig drivers, and small-business owners deduct vehicle costs using the standard mileage rate: a flat amount per business mile that bundles gas, oil, maintenance, repairs, tires, insurance, registration, and depreciation into one number. Instead of saving every fuel receipt, you track the miles you drive for work and multiply them by the rate. This calculator does exactly that — business miles times the rate equals your estimated deduction. The default is $0.67 per mile, but the IRS updates the rate every year (and occasionally mid-year), so the field is fully editable; check IRS.gov for the figure that applies to the year you are filing. If you also enter your total annual miles, the tool shows your business-use percentage — a number your tax preparer will ask for. These results are estimates only and not professional, financial, or tax advice.

How to use it

  1. Enter the business miles you drove during the tax year, taken from a mileage log, a tracking app, or odometer records.
  2. Confirm or edit the IRS standard rate per mile for your filing year.
  3. Optionally add your total miles driven (business plus personal) to see your business-use percentage and non-deductible personal miles.
  4. Read your estimated deduction instantly — results update live and nothing ever leaves your browser.

FAQ

What counts as business miles?
Driving between job sites, to client meetings, to pick up supplies, to the bank or post office for business, and travel between a home office and other work locations. Keep a contemporaneous log with dates, destinations, and purpose — the IRS expects records.
Does my commute count?
No. Driving from home to a regular workplace is personal commuting and is never deductible, even if you take work calls on the way.
Standard mileage or actual expenses — which is better?
The standard rate is simpler. The actual-expense method deducts real costs (fuel, repairs, depreciation) multiplied by your business-use percentage, which can win for expensive vehicles. Run both and compare, or ask a tax professional.
Why is the rate editable?
The IRS sets a new rate each year and sometimes adjusts it mid-year. Editing the rate also lets you model medical, moving, or charitable mileage, which use different per-mile rates.
