About Real Charge Cost

Ask what an electric car costs to charge and you'll get a national average. That number can't tell you much, because your cost depends on your electricity rate — and rates vary by more than three to one across the US.

This site swaps the average for your numbers. The calculators do the math, and the articles explain what's behind it.

Where our numbers come from

Published utility rates, manufacturer specs, and public data. When a figure is an estimate, we say so and show the assumption behind it.

Keeping the numbers current

Energy prices move monthly, so a number that was right in the spring can be wrong by the autumn. We re-check the figures regularly — and your own bill is always the final word.

Spotted a mistake? Please tell us — numbers go out of date, and we'd rather fix one than leave it there. Get in touch. If you want to check our working first, here's how we calculate every cost on this site.
