How It Works
True vehicle cost includes much more than just the monthly payment. This calculator accounts for all major ownership expenses to give you an accurate cost per mile and total ownership cost.
The basic rule:
- Depreciation is estimated by age: ~20% year 1, ~15% year 2, ~12% year 3, ~10% year 4, ~8% year 5+
- Fuel cost = (miles/year ÷ MPG) × price per gallon
- Loan interest is calculated with standard amortization over the loan term
The IRS standard mileage rate for 2024 is $0.67/mile, which covers all vehicle costs. If your calculated cost per mile is higher, you may want to look for ways to reduce expenses. If it's lower, you're doing well.
Tips & Considerations
- Double-check your purchase price before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both cost per mile and monthly cost — they work together to give you the full picture.
- Bookmark this page for quick access next time you need to maintain your vehicle.
- If you're unsure about your vehicle age, start with a conservative estimate and adjust from there.
Frequently Asked Questions
What is the average cost per mile to drive a car?
According to AAA, the average cost to own and operate a new car is about $0.60-0.80 per mile, depending on vehicle type. Small sedans average around $0.55/mile while pickup trucks average $0.80/mile. This includes depreciation, fuel, insurance, maintenance, and financing.
What costs the most in vehicle ownership?
Depreciation is typically the single largest cost, especially for new vehicles. A new $35,000 car loses roughly $7,000 in the first year alone. After depreciation, fuel and insurance are usually the next largest expenses, followed by maintenance and financing costs.
How do I reduce my cost per mile?
Buy used (avoid the steepest depreciation), choose a fuel-efficient vehicle, shop insurance rates annually, learn basic maintenance, and drive more miles per year to spread fixed costs. Driving 15,000 miles vs 10,000 miles reduces your per-mile cost significantly.
Should I include depreciation in cost per mile?
Yes. Depreciation is real money lost — it's the difference between what you paid and what the car will be worth when you sell it. Ignoring depreciation dramatically understates the true cost of ownership, especially for newer vehicles.
Is it cheaper to buy or lease?
For most people who drive average miles and keep cars 5+ years, buying is cheaper long-term. Leasing can be cheaper monthly but you always have a payment, never build equity, and face mileage penalties. Buying used 2-3 year old cars is typically the most economical option.
How does mileage affect cost per mile?
Higher annual mileage reduces cost per mile because fixed costs (depreciation, insurance, registration) are spread across more miles. However, it increases total annual spending and accelerates wear. There's a sweet spot around 12,000-15,000 miles/year for most people.
