How to Use the EV Charging Cost Calculator

Enter your EV's energy consumption rate, your electricity rate (home or public charging), and typical mileage — the calculator shows your cost per mile and can project monthly or annual charging costs, useful for budgeting or comparing directly against a gas vehicle's running cost.

The EV Charging Cost Calculator applies the full cost-per-mile calculation — here's what to enter.

Entering vehicle efficiency and electricity rate

Enter your EV's official energy consumption rating (or your own observed real-world figure, if available and different) and your actual electricity rate — as covered in the true-cost guide, using an accurate rate rather than a generic default gives a more personally meaningful result.

Comparing home and public charging scenarios

Running the calculation separately for home and public charging rates (as covered in the home-vs-public comparison) shows the real cost difference between the two, useful for planning a charging strategy that manages overall cost.

Frequently asked questions

Does the calculator account for charging inefficiency?

Check whether the specific tool includes an efficiency-loss adjustment — as covered in the higher-than-expected-cost guide, actual electricity drawn during charging is somewhat higher than the battery's net energy gain, which a more detailed calculation can account for.

Can I use this to directly compare against a gas vehicle's cost?

Yes — running this calculator for your EV and the Gas Mileage Calculator for a comparable gas vehicle, then comparing the resulting cost-per-mile figures directly, gives a fair, apples-to-apples running cost comparison between the two.
