EV Efficiency in Miles per kWh Calculator

mi/kWh = total miles / total kWh used; Wh/mi = 1000 / (mi/kWh).

Compute an electric vehicle's energy efficiency from total miles driven and total kWh consumed (from charging records or the dashboard). Reports miles per kWh, watt-hours per mile (the EPA-style metric), and an estimated range based on your usable battery capacity.
