What this calculator estimates
Compare annual gasoline and electric-vehicle energy costs for the same driving distance.
How to use it
Enter Annual miles driven; Gas vehicle fuel economy (MPG); Gas price per gallon ($); EV energy use (kWh per 100 miles); Electricity price per kWh ($). Select Calculate to update the results.
How the calculation works
Gas cost is annual miles divided by MPG times gas price. EV cost is annual miles times kWh per 100 miles times the electricity rate.
Worked example: starting scenario
| Annual miles driven | 12000 |
|---|---|
| Gas vehicle fuel economy (MPG) | 28 |
| Gas price per gallon ($) | 3.5 |
| EV energy use (kWh per 100 miles) | 30 |
| Electricity price per kWh ($) | 0.17 |
| Estimated annual savings | EV saves $888.00 / year |
|---|---|
| Gas vehicle annual energy cost | $1,500.00 |
| EV annual charging cost | $612.00 |
| Five-year energy difference | $4,440.00 |
Important limitations
Vehicle price, charging losses, maintenance, insurance, taxes and changing energy prices are excluded.
Use comparable driving and energy assumptions
Keep annual miles equal when comparing gasoline and electricity. Home charging prices, public charging prices and charging losses can differ, while fuel economy and electricity use depend on the vehicle and conditions. The comparison includes only the purchase and running-cost fields shown; an energy saving alone is not the full ownership saving.
