Annual Vehicle Operating Cost Calculator
Calculate the true annual cost of owning and operating your vehicle by entering all cost categories: fuel, insurance, maintenance, registration and taxes, loan interest, and depreciation. The calculator totals everything and shows your true cost per mile. All fields are editable so you can enter your actual costs or use the provided typical values as a starting point.
Vehicle operating cost formula
Total annual cost = Fuel + Insurance + Maintenance + Registration + Depreciation + Loan_interest
Cost per mile = Total_annual / Annual_miles
Monthly cost = Total_annual / 12
IRS comparison = Annual_miles x 0.70 (2025 standard rate)
The IRS 2025 standard mileage rate of 70 cents per mile provides a useful benchmark. If your actual cost per mile is lower than 70 cents, you are spending less than the IRS average. The IRS rate is updated annually (IRS Rev. Proc.).

Annual vehicle cost calculator: frequently asked questions
What is the true annual cost of owning a car?
AAA's annual Your Driving Costs study breaks vehicle ownership into: depreciation, loan interest, insurance, maintenance and repairs, fuel, registration fees, and taxes. For 2023, AAA found the average total cost for a new medium sedan was about $10,728 per year ($0.765 per mile at 14,000 miles/year). SUVs and trucks typically cost more; small cars cost less.
What does the IRS standard mileage rate cover?
The IRS standard mileage rate (70 cents/mile for 2025) is intended to cover the full variable cost of operating a vehicle for business purposes: fuel, maintenance, tires, depreciation, and a portion of insurance. Taxpayers who use the standard mileage rate cannot separately deduct these expenses (IRS Publication 463). The rate is announced annually in December.
Should I use actual costs or the IRS standard mileage rate for taxes?
If the actual cost method yields a higher deduction, use actual costs. If the standard mileage rate is simpler and your actual costs are lower, use the standard rate. You must choose the method in the first year you use a vehicle for business. Switching from standard mileage to actual costs is allowed in some circumstances but not the reverse (IRS Revenue Procedure).
How do I estimate annual insurance cost?
Average annual auto insurance premiums vary widely by state, age, driving record, vehicle type, and coverage level. The National Association of Insurance Commissioners (NAIC) publishes average premium data by state annually. The US average for full-coverage auto insurance was approximately $2,000 to $2,500 per year as of 2024. Enter your actual premium for an accurate calculation.
What is typically included in vehicle maintenance costs?
Regular maintenance includes oil changes, tire rotation, air filter replacement, brake fluid, transmission service, wiper blades, and tire replacement. AAA estimates maintenance and repair costs for a new mid-size sedan at approximately $1,200 to $1,500 per year over 5 years. Older vehicles typically cost more as wear items need replacement.
