EV Charging Cost Calculator

Charging an EV at home is usually far cheaper than petrol, but the exact cost depends on your efficiency and electricity rate. This calculator works out your cost per mile, per day and per month.

How it works

Energy used = miles ÷ efficiency, then divided by (1 − charging losses) to account for power lost while charging. Cost = energy × your electricity rate. We scale the daily figure to 30.4 days per month and 365 days per year.

Frequently asked questions

How much does it cost to charge an EV at home?

For a typical EV at 3.5 mi/kWh and $0.17/kWh, expect roughly 5 cents per mile — far less than petrol. Enter your own numbers above for an exact figure.

What are charging losses?

Some electricity is lost as heat in the charger and battery, so you draw more from the wall than ends up in the battery. 8–15% is typical for home AC charging.

Does this include public fast charging?

No — this assumes home charging. Public DC fast charging usually costs 2–4× more per kWh.
