A mile road trip costs about $16.50 in energy.

EPA electricity consumption is measured from the wall outlet, so typical home AC charging losses are already included. Public DC fast-charging prices, extreme temperatures, and driving style can change real-world cost.

Official FuelEconomy.gov estimate: $650/year — assumes 15,000 miles/year and EPA price assumptions. The figures above use your inputs instead.
