Estimated actual vehicle cost
IRS optional mileage rate
$0.725/mile applied Jan 1–Jun 30, 2026. The IRS rate is not your actual vehicle cost, a guaranteed reimbursement, or an automatic tax deduction.
Tax-method eligibility and switching rules vary based on vehicle ownership or lease circumstances and choices made in earlier years. Do not assume you can freely choose the larger result every year. Review IRS Topic No. 510 or consult a qualified tax professional.
Amount remaining after modeled vehicle costs
Gross work amount minus modeled vehicle cost only. This is not profit, take-home pay, reimbursement, or taxable income. It excludes labor, platform fees, income and self-employment taxes, and other business expenses.
How the estimate works
Formula
Annual fuel = annual miles ÷ MPG × fuel price. Maintenance and tires are entered per mile and multiplied by annual miles once. Annual ownership and other costs are added once. Estimated actual cost per mile = total annual vehicle cost ÷ annual miles.
Included and excluded
Includes only the entered gasoline, maintenance, tires, insurance, registration/taxes, interest, depreciation, tolls/parking, and other vehicle costs. This gasoline model does not calculate EV electricity. It excludes loan principal, labor, income taxes, platform fees, and any unentered expense.
