How it works
- Enter yearly miles and how long you will keep the car.
- Set gas price, mpg and maintenance for the gas car.
- Enter the EV price premium, kWh per mile and charging mix.
- Read yearly savings and when the premium pays back.
Where the savings come from
Electric cars usually cost less per mile in energy and maintenance, but often cost more to buy. The question is how long the running savings take to repay the price premium.
Charging mix matters most
Home charging is cheap. Public fast charging can cost as much per mile as gas. If you cannot charge at home, savings shrink or vanish.
