Find an electric car's cost per mile and per 100 miles.
Dividing the per-kWh electricity price by the car's miles per kWh yields the per-mile energy cost, then scaled to 100 miles and a full year. Per-mile energy cost is what lets an EV be priced against a gas car fairly, and it varies widely with tariff and charging method.
EV Cost per Mile
Per mile = electricity rate / miles per kWh
Per mile = electricity rate / miles per kWh Dividing the per-kWh electricity price by the car's miles per kWh yields the per-mile energy cost, then scaled to 100 miles and a full year.
Per-mile energy cost is what lets an EV be priced against a gas car fairly, and it varies widely with tariff and charging method.
This calculator takes 3 inputs: Electricity rate, EV efficiency, Miles per year. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
