🚗 Miles to Dollars

How to Use This Calculator

Enter the miles driven and pick the purpose: business, medical/moving, charity, or a custom rate. The calculator multiplies miles by the 2026 IRS rate for that purpose and shows the dollar figure, the rate used, and what the same miles would be worth under each other category. The business default is 76 cents per mile, the July-to-December 2026 rate. If your miles were driven January through June 2026, use the custom rate field with 72.5 for business or 20.5 for medical.

The Method: Miles Times Rate

The rate bundles fixed costs (depreciation, insurance, registration) and variable costs (fuel, maintenance) into one number, which is why it dwarfs pure fuel cost per mile. The IRS sets it annually from cost studies and adjusts mid-year only when fuel moves a lot, as in July 2026. The charity rate's decades-long freeze at 14 cents is a legislative artifact, not an economic estimate. Split-year miles need split rates: 500 miles in March plus 500 in September 2026 means 500 x 0.725 + 500 x 0.76 = $742.50, not $760. The custom rate field handles exactly this.

Worked Example

A real estate agent drives 1,200 business miles in October 2026. Rate: 76 cents (July-December). Value = 1,200 x 0.76 = $912. Her employer reimburses $912 tax-free under an accountable plan. If she had driven those miles in April, the rate would be 72.5 cents and the value $870, a $42 difference from the mid-year change. A volunteer driving 1,200 charity miles gets 1,200 x 0.14 = $168 of deduction value. Enter 1200 with each purpose above and the calculator shows all three figures side by side.

Keeping a Bulletproof Mileage Log

The IRS requires contemporaneous records: date, destination, business purpose, and miles, recorded near the time of the trip. Reconstructed logs get disallowed; auditors know what a real log looks like. Odometer readings at year start and end anchor the total; the business percentage is business miles over total miles. Commuting is never deductible, but the home-office exception converts qualifying home-to-client trips. Apps with GPS tracking produce the strongest records; a notebook in the glove box works if you actually use it daily.

Reimbursement Strategy

Employees should push for accountable-plan reimbursement at the IRS rate: it is tax-free and requires no tax return gymnastics. Self-employed filers choose between standard rate and actual expenses in year one and live with the choice. Actual expenses win for luxury vehicles, heavy depreciation, or very high insurance; standard rate wins for economy cars and simplicity. Either way, the log is non-negotiable. And never mix personal miles into business totals; the IRS treats that as exactly what it is.

General tax information, not tax advice. Rates and rules change; verify current IRS guidance or consult a tax professional for your situation.

Record Keeping the IRS Accepts

The mileage deduction lives or dies on records. The IRS wants a contemporaneous log: date, destination, business purpose, and miles for each trip. "Contemporaneous" means recorded near the time, not reconstructed at tax season; a mileage app that logs automatically is the gold standard, but a notebook in the car works. Estimates and round numbers invite disallowance: 12,000 exactly looks invented, while 11,847 looks logged. Keep the log with your tax records for at least 3 years (6 if you underreported income substantially). Commuting from home to a regular workplace is never deductible, but home-to-temporary-worksite and between-worksites trips are. The distinction trips up more filers than the rate itself. If your employer reimburses at or below the IRS rate under an accountable plan, the reimbursement is tax-free and you claim nothing further.

Rideshare and Delivery Driver Math

For Uber, Lyft, and delivery drivers, mileage is usually the biggest deduction, often bigger than the platform fees. Deductible miles include driving to pickups, between rides, and repositioning, not just miles with passengers; most drivers undercount by logging only "active" miles. Track with an app that runs during every shift, and separate personal detours honestly. The standard mileage rate versus actual expenses choice matters: high-mileage drivers in cheap cars almost always win with the standard rate, while low-mileage drivers in expensive vehicles should run both calculations. Remember the rate covers gas, maintenance, insurance, and depreciation bundled; you cannot also deduct those separately. Set aside the tax savings per mile as you earn: roughly a quarter of the deduction's value, so the April bill never surprises you.

A Second Worked Example: The Charity Miles

Volunteering all year: 800 miles driving for a registered charity. Charity rate: 14 cents all year, set by law. Value: 800 times 0.14 is $112. Compare the same 800 miles as business in late 2026: 800 times 0.76 is $608. The charity rate's decades-long freeze shows in the gap; it is a policy number, not a cost number. Track charity miles anyway: $112 of deduction beats $0, and the log habit carries over to the business miles that pay real money.

Moving miles for active-duty military use the medical/moving rate, not the business rate: the category follows the purpose, and the purpose follows the documentation. Log the purpose per trip, not per year, because one year often contains several.

Standard Rate vs. Actual Expenses

The IRS offers two methods: the standard mileage rate or actual expenses (gas, insurance, depreciation, repairs, apportioned by business use). The standard rate wins on simplicity: one multiplication, no receipts for every oil change. Actual expenses can win on dollars for expensive cars with high operating costs, but they demand detailed records and depreciation schedules.

You cannot freely hop between methods for the same car in all cases, so the first-year choice matters; check the current IRS rules before committing. Most drivers with ordinary cars do better with the standard rate and a good log. The calculator's job is valuing the miles; the method choice is a tax-planning question for you or your preparer.

Common Mileage-Log Mistakes

First: commuting. Driving from home to your regular workplace is commuting, not business, and it is not deductible no matter how far. Home-office workers have different rules; regular commuters have none. Second: round numbers. A log reading 5,000 miles exactly invites skepticism; real logs have odd numbers because real trips do.

Third: the split-year rate. January-to-June 2026 miles rate differently than July-to-December; mixing them at one rate misstates the deduction. Fourth: missing purpose. The IRS wants date, miles, destination, and business purpose per trip; miles alone are not a log. Fifth: reconstructing from memory. Rebuilt logs fail audits; contemporaneous records, even a phone note per trip, survive them.
