EV Cost per Mile
Find an electric car's cost per mile and per 100 miles.
About EV Cost per Mile
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.
Formula
EV Cost per Mile
Per mile = electricity rate / miles per kWh
- miles per kWh
- Consumption expressed as distance per energy
Worked example
With the default values below, EV Cost per Mile returns Cost per Mile of $0.0429. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax or fees or charges into account.
- Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is EV Cost per Mile calculated?
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.
Why does EV Cost per Mile matter?
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.
What values do I need to enter?
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.
