Calculator Inputs
Use the form below to estimate your true driving cost per mile.
Formula Used
This calculator combines variable and fixed ownership costs, then spreads them across annual miles.
Fuel Price per Gallon ÷ Miles per Gallon
Annual Maintenance Cost ÷ Annual Miles Driven
Tire Set Cost ÷ Tire Life Miles
(Purchase Price − Resale Value) ÷ Ownership Years ÷ Annual Miles
Each Annual Cost ÷ Annual Miles Driven
Fuel + Maintenance + Tires + Parking/Tolls + Insurance + Registration + Depreciation + Financing

Frequently Asked Questions
1. What does cost per mile mean?
Cost per mile is the average amount you spend for each mile driven. It includes fuel and spreads annual and ownership costs across your yearly mileage for a more complete estimate.
2. Why include depreciation?
Depreciation reflects how much value your car loses over time. It is one of the largest ownership costs, so leaving it out can make your true per-mile driving cost look much lower than reality.
3. Is fuel the biggest cost component?
Not always. For newer vehicles, depreciation can exceed fuel costs. For older vehicles with low resale value loss, fuel and maintenance may dominate the total cost per mile instead.
4. Should insurance be counted per mile?
Yes. Insurance is usually paid monthly or yearly, but it still supports driving. Dividing it by annual miles helps show how much of each mile’s cost comes from fixed ownership expenses.
5. What annual mileage should I use?
Use your most realistic annual driving estimate. If you drive more, fixed costs are spread over more miles. If you drive less, your cost per mile usually rises.
6. Can this calculator help compare vehicles?
Yes. Enter different MPG, depreciation, tire, maintenance, and insurance assumptions for each vehicle. Comparing total cost per mile makes ownership decisions much easier and more practical.
7. Does this include repair emergencies?
Only if you include them in annual maintenance. For better planning, raise the maintenance estimate when a vehicle is older or likely to need major repairs soon.
8. Why use both CSV and PDF downloads?
CSV is useful for spreadsheets, cost tracking, and comparisons. PDF is better for sharing, printing, or saving a formatted summary of your current calculation and chart.
