See the yearly cost to power an electric car versus fueling a gas one.
An electric-vs-gas calculator compares the annual energy cost of driving an electric car with fueling a gasoline one, based on your mileage and local energy prices.
Fueling cost per mile is what you drive divided by efficiency, times the energy price. For a gas car that's miles ÷ MPG × price per gallon; for an EV it's miles ÷ miles-per-kWh × price per kWh. EVs are usually cheaper to power per mile, though how much depends heavily on your local electricity rate versus gas price.
This compares fuel and electricity only. The full ownership picture also includes purchase price, incentives, maintenance (EVs typically need less), insurance, and battery considerations. EVs often cost more upfront but less to run and maintain, so the total-cost comparison depends on how many miles you drive and how long you keep the car.
Usually yes on energy cost per mile, but it depends on your local electricity and gas prices. Enter both above to compare.
Purchase price, incentives, maintenance, and insurance, EVs often cost more upfront but less to run and maintain.
Gas: miles ÷ MPG × price per gallon. Electric: miles ÷ miles-per-kWh × price per kWh.
