    US EV charging calculator — cost, range and charge time

    Figures are estimates based on US electricity rates and EPA efficiency data — your real numbers will vary with weather, speed, and driving style.

    Charging cost depends on how much energy your battery needs (measured in kilowatt-hours, or kWh) and what that electricity costs at the source. Home charging on a time-of-use tariff is by far the cheapest option, typically under 10¢/kWh off-peak. Level 2 public chargers run around 25–40¢/kWh, while DC fast chargers can reach 50¢/kWh or more. Range varies with speed and conditions — city driving benefits from regenerative braking, while steady highway driving at 70+ mph draws more energy per mile. Efficiency figures use EPA combined cycle ratings, which run roughly 15–20% lower than European WLTP figures for the same vehicles.
