Compare EV and gas costs together easily. Add purchase, resale, charging, fuel, and upkeep inputs. Make smarter car decisions today with better cost insight.
| Item | Example EV | Example Gas |
|---|---|---|
| Annual miles | 12,000 | 12,000 |
| Years owned | 5 | 5 |
| Purchase price | $45,000.00 | $32,000.00 |
| Rebate or tax credit | $7,500.00 | $0.00 |
| Resale value | $20,000.00 | $12,000.00 |
| Efficiency | 29 kWh per 100 miles | 32 MPG |
| Energy or fuel price | $0.16 per kWh | $3.80 per gallon |
| Annual maintenance | $450.00 | $850.00 |
| Annual insurance | $1,400.00 | $1,350.00 |
| Annual registration and fees | $250.00 | $180.00 |
| Estimated total cost | $35,361.31 | $43,344.14 |
| Estimated cost per mile | $0.59 | $0.72 |
Total miles = Annual miles × Years owned
EV effective kWh per 100 miles = EV kWh per 100 miles × (1 + Charging loss percent ÷ 100)
EV energy cost = (Total miles ÷ 100) × Effective EV kWh per 100 miles × Electricity price
Gas fuel cost = (Total miles ÷ Gas MPG) × Gas price per gallon
Depreciation cost = Net purchase price − Resale value
Finance interest = Loan interest paid during the ownership period only
Total ownership cost = Depreciation + Energy or fuel + Maintenance + Insurance + Registration + Finance interest
Cost per mile = Total ownership cost ÷ Total miles
Buying a vehicle is only the first expense. Daily driving costs shape the real budget. This calculator helps compare EV cost per mile and gas car cost per mile using practical ownership data. It includes depreciation, energy or fuel spending, insurance, registration, maintenance, and finance interest. That gives a fuller picture than fuel alone. Many drivers only compare pump prices and electric rates. That approach misses major long term costs. A clear side by side comparison helps you estimate which vehicle fits your mileage, local utility rates, and ownership plan.
Annual miles matter a lot. High mileage usually improves EV value because electricity often costs less per mile. Efficiency also matters. For EVs, the calculator uses kilowatt hours per hundred miles and charging loss. For gas vehicles, it uses miles per gallon and fuel price. Purchase price and resale value drive depreciation. Insurance, registration, and maintenance can shift results too. Incentives reduce the EV net purchase cost. Loan settings add interest without double counting the vehicle price. These details help create a more accurate ownership cost per mile estimate.
The result section shows total ownership cost, annual cost, monthly cost, and cost per mile for each vehicle. It also shows the savings difference. If the EV cost per mile is lower, the electric option may reduce long term operating expense. If the gas vehicle wins, your current fuel price, purchase price, or mileage pattern may favor gasoline. Review the fuel and energy line items first. Then review depreciation. Those two categories often explain most of the gap. Use the example table as a guide before entering your own numbers.
This page works well for personal budgeting, dealership comparisons, company fleet planning, and transportation cost reviews. Try different gas prices, utility rates, and resale values to test best and worst case scenarios. Small input changes can move the result fast. That makes sensitivity testing useful. When you compare several ownership periods, you can see when an EV starts saving more. Use the CSV export for records. Use the PDF option when sharing estimates with family, clients, or team members. Local insurance and registration fees also deserve close attention during every comparison.
Cost per mile shows how much each driven mile costs after combining depreciation, energy or fuel, maintenance, insurance, registration, and finance interest.
Depreciation is often one of the biggest ownership costs. Excluding it can make a vehicle look cheaper than it really is over time.
Charging loss reflects electricity lost during charging. The battery receives less power than the wall supplies, so true EV energy cost is slightly higher.
Yes. Add eligible incentives or tax credits to reduce the EV net purchase price. That lowers depreciation and can improve the EV cost per mile result.
Yes. Enter the actual used purchase price, expected resale value, and your local energy or fuel costs. The formulas work for new and used vehicles.
It can. Higher APR or a smaller down payment increases interest paid during the ownership period. That can noticeably change total cost per mile.
Low mileage usually reduces fuel savings from an EV. In that case, depreciation and fixed annual costs may matter more than energy savings.
Annual miles, purchase price, resale value, gas price, electricity price, and efficiency usually have the strongest impact. Test several scenarios for better planning.
