EV calculators
Running an electric car is cheap in some states and barely cheaper than gas in others, and the difference is your local electricity rate. These calculators use the EIA's residential rate for your state rather than a national average, so the cost per mile you get is the one you would actually pay on your driveway.
- EV Charging Cost CalculatorCompare EV charging cost per mile at home, on public DC fast chargers, and against gasoline, using EIA electricity rates for your state.
- EV Charging Time CalculatorEstimate how long it takes to charge your electric vehicle from your battery size, charger power, and charge levels.
- EV vs Gas Savings CalculatorCompare fuel cost and total ownership savings between an electric vehicle and a gas car based on your driving and local prices.
- EV Range CalculatorEstimate how far you can drive on your current charge, in kilometres or miles, from any efficiency unit — kWh/100 km, Wh/km, km/kWh or mi/kWh.
The EV vs gas savings calculator is the one to run. It compares cost per mile, per month, and per year at your state's real rate, and returns the mileage at which the EV's higher purchase price is paid back by cheaper fuel.
The charging cost calculator splits home charging from public DC fast charging, which is usually two to three times more expensive per kWh. Knowing your own split is what turns a rough monthly estimate into an accurate one.
The range calculator adjusts a rated range for cold weather, highway speed, and load — the three things that account for most of the gap between the window sticker and reality. The charging time calculator converts a battery size and charger power into an actual number of hours.
