— SHOULD I GO ELECTRIC?
Home charging is where EV savings can really add up.
An electric vehicle can be most economical when it charges overnight at home instead of relying primarily on public Level 3 charging. Use the calculator above to compare your estimated home EV charging cost with Supercharger use and a gasoline vehicle.
The comparison changes with your vehicle and driving habits. A more efficient EV uses fewer kilowatt-hours per mile, while higher annual mileage can make the difference between home charging and gasoline more noticeable.
Is charging an EV at home cheaper than buying gas?
For many drivers, yes. Your exact savings depend on annual mileage, the EV's efficiency, your electric rate, gasoline prices and the fuel economy of the gas vehicle being compared.
Is home EV charging cheaper than using Superchargers?
Home charging is generally less expensive when your residential electricity rate is below the public fast-charging price. This calculator compares $0.14/kWh at home with $0.49/kWh for Level 3 or Supercharger use.
How does this EV savings calculator work?
It estimates the electricity your selected EV uses based on miles driven, then applies the displayed home and public charging rates. The gasoline comparison uses 25 MPG and $4.50 per gallon.
