Formula used
Gross purchase cost = Purchase price + Sales tax + Dealer fees + Charger installation
Net acquisition cost = Gross purchase cost − Federal incentive − State incentive − Utility rebate
Battery energy = Miles × (kWh per 100 miles ÷ 100)
Grid energy = Battery energy × (1 + Charging loss %)
Energy cost = (Grid kWh × Home share × Home rate) + (Grid kWh × Public share × Public rate)
Tire cost per year = (Annual miles ÷ Tire life miles) × Tire set cost
Depreciation cost = Net acquisition cost − Resale value
Total cost of ownership = Depreciation + Financing interest + Operating costs
How to use this calculator
- Enter purchase price, taxes, fees, charger installation, and incentives.
- Add financing values if the EV will be purchased with a loan.
- Enter annual miles, efficiency, charging split, and electricity rates.
- Add yearly insurance, registration, maintenance, repairs, tires, and other costs.
- Set the expected ownership period and estimated resale value.
- Press Calculate Lifetime Cost to show the summary above the form.
- Use the CSV or PDF buttons to save the report.
- Review the graph and yearly table to understand where lifetime costs accumulate.
Frequently asked questions
1) What does this EV lifetime cost calculator estimate?
It estimates total ownership cost over your selected years. The result combines depreciation, finance interest, charging, insurance, registration, maintenance, repairs, tires, and other recurring expenses.
2) Why is resale value included?
Resale value reduces the capital cost of owning the vehicle. A higher resale estimate lowers depreciation and can meaningfully reduce total cost of ownership.
3) Does the calculator handle loan interest?
Yes. It estimates monthly payment, interest paid during your ownership window, and remaining balance if the loan lasts longer than ownership.
4) Why do charging losses matter?
Charging losses mean the wall supplies more electricity than the battery stores. Including losses makes charging cost estimates more realistic.
5) Can I use mixed charging rates?
Yes. Enter the percentage charged at home and the public charging rate. The calculator blends both costs into a single annual charging estimate.
6) Should I include charger installation?
Usually yes. Home charger equipment and installation are real ownership costs and should be included when comparing long-term EV expenses.
7) What is cost per mile useful for?
Cost per mile helps compare different vehicles, ownership periods, and driving patterns. It is especially useful when evaluating two EVs or an EV against a gas vehicle.
8) Are the results exact?
No. They are planning estimates based on your inputs. Actual outcomes depend on energy prices, driving style, insurance changes, repairs, resale markets, and incentives.
