Question 1

How much does it really save to go electric?

Accepted Answer

For a typical driver charging at home, an EV cuts the per-mile fuel cost by roughly half to three-quarters versus a gas car — often $800–$1,500 a year. But it depends on your miles, prices and the cars, which is exactly what this tool works out for your case.

Question 2

Is charging an EV actually cheaper than gas?

Accepted Answer

At home, almost always — electricity per mile is much cheaper than gasoline. Public DC fast charging is far pricier and can approach the per-mile cost of gas, so the home-vs-public slider matters. Set it to how you'd really charge.

Question 3

What's a good electricity rate to use?

Accepted Answer

Use the price per kWh from your electric bill. We pre-fill your state's average, but your real rate (especially a cheaper overnight EV rate) gives the most accurate answer.

Question 4

Does this include the EV's higher purchase price?

Accepted Answer

Only if you want it to. The main result compares fuel cost. Click "add the cars' prices" to enter both stickers and any tax credit, and we'll show the break-even — how long the fuel savings take to repay the price difference.
