Example Data Table
This sample uses the default numbers included in the form. Values are rounded for display.
| Purchase Price | Ownership Years | Annual Miles | Efficiency | Blended Rate | APR | Lifetime Cost | Cost per Mile |
|---|---|---|---|---|---|---|---|
| $42,000 | 8 | 12,000 | 3.8 mi/kWh | $0.184/kWh | 5.5% | $72,259.22 | $0.753 |
Formula Used
- Sales tax = Vehicle price × Sales tax rate
- Net acquisition cost = Vehicle price + Sales tax + Charger install − Incentives
- Annual charging use = Annual miles ÷ Miles per kWh
- Blended charging rate = (Home rate × Home share) + (Public rate × Public share)
- Yearly charging cost = Annual charging use × Blended rate × (1 + Inflation)year−1
- Loan payment = P × r × (1 + r)n ÷ ((1 + r)n − 1)
- Nominal lifetime cost = Net acquisition + Finance interest + Lifetime operating costs − Resale value
- Present value cost = Net acquisition + Discounted finance interest + Discounted future costs − Discounted resale value
- Cost per mile = Nominal lifetime cost ÷ Total miles driven
How to Use This Calculator
- Enter the EV purchase price, incentives, sales tax, and charger installation cost.
- Add financing details if you expect to use a loan. Enter zero for APR or loan term if paying cash.
- Provide annual miles, efficiency, home rate, public rate, and public charging share.
- Fill in yearly insurance, registration, maintenance, tires, and other recurring driving costs.
- Set an operating inflation rate to model future increases in charging and recurring expenses.
- Enter battery replacement timing and cost only if you want that event included.
- Add an estimated resale value and discount rate, then submit the form.
- Review the result table, cost summary cards, Plotly charts, and export buttons.
Frequently Asked Questions
1) What does lifetime cost include?
It includes acquisition cost, finance interest, charging, insurance, registration, maintenance, tires, other annual costs, optional battery replacement, and a resale deduction at the end.
2) Does the calculator support cash purchases?
Yes. Set loan APR and loan term to zero. The tool will remove finance interest and treat the vehicle as a cash purchase.
3) Why is there a present value result?
Present value discounts future costs to today’s dollars. It helps compare long ownership plans against other investments or alternative vehicle choices.
4) How is charging cost estimated?
The calculator finds yearly kWh use from miles and efficiency, then applies a blended electricity rate based on your home and public charging mix.
5) Should I include battery replacement?
Only include it when you believe a replacement is likely during your ownership period. If not needed, enter zero for the replacement year.
6) Does this model include depreciation?
Yes. Depreciation is reflected through the gap between the vehicle’s taxed purchase basis and the resale value you expect at sale.
7) What if public charging prices vary a lot?
Use a blended estimate that reflects your expected real-world charging mix. You can rerun the calculator with different shares to test best and worst cases.
8) Is this good for comparing two EVs?
Yes. Run the tool once for each vehicle using the same ownership years and mileage. Then compare cost per mile, total cost, and present value.
