This is a rough estimate. Real costs depend on weather, speed, time-of-use rates and your car. With AskMyEV connected, your AI app can work from your car's logged charging sessions instead of guesses.

Frequently asked questions

How do I find my Tesla's Wh per mile?

Open the Energy app or a trip meter in the car. Lifetime averages are usually more realistic than a single trip.

Why add charging losses?

Some energy is lost as heat while charging, so the wall meter reads a bit more than what reaches the battery.
