EV vs gas cost calculator
Is an EV cheaper to fuel than a gas car where you live? Pick your state to load EIA prices, then adjust anything. You'll see the yearly energy cost of each, in dollars.

Yearly energy cost
| Cost per 100 miles (Electric) | — |
| Cost per 100 miles (Gas car) | — |
| Electricity used (kWh/yr) | — |
| Average price paid per kWh | — |
| Break-even price per kWh | — |
What your result means: the big number is how much you'd save (or spend extra) a year on energy by driving electric. The break-even price is the most you could pay per kWh before the EV stops being cheaper to run. This is energy only, so purchase price and other costs aren't counted.
Energy only: no purchase price, insurance or maintenance. Estimates, not financial advice.
