Is charging an EV cheaper than buying gas?

Often yes, especially when you charge at home on a standard or off-peak residential rate, but it depends on your local electricity price, gas prices and the vehicles you are comparing. Relying mostly on DC fast charging can narrow or even erase the savings. Fueleconomy.gov has a side-by-side tool to compare estimated annual fuel costs for specific models. On OffLot, you can compare vehicles side by side and look at the total cost on each vehicle page.
