What this calculator estimates
Compare monthly electric-vehicle charging cost with a gasoline vehicle.
How to use it
Enter Miles driven per month; EV efficiency (kWh per 100 miles); Electricity rate ($/kWh); Gas vehicle MPG; Gas price ($/gallon). Select Calculate to update the results.
How the calculation works
Monthly electricity use = miles driven × kWh per 100 miles / 100. Charging cost multiplies that use by the electricity price per kWh. Gasoline comparison cost = miles / MPG × price per US gallon. Savings subtract charging cost from the gasoline comparison.
Worked example: starting scenario
| Miles driven per month | 1000 |
|---|---|
| EV efficiency (kWh per 100 miles) | 30 |
| Electricity rate ($/kWh) | 0.18 |
| Gas vehicle MPG | 28 |
| Gas price ($/gallon) | 3.5 |
| Estimated monthly EV charging cost | $54.00 |
|---|---|
| Electricity used | 300 kWh |
| Comparable gasoline cost | $125.00 |
| Estimated monthly savings | $71.00 |
Important limitations
Efficiency is entered in kWh per 100 miles, not miles per kWh. Use wall-meter energy consumption if you want charging losses included. Charging fees, time-of-use price changes, fuel-price changes, maintenance and vehicle purchase costs are excluded.
