EV Charging Cost Calculator

What charging costs depends on your electricity rate, and rates vary by more than three to one across the US.

The boxes below start with example numbers. Replace them with yours — the rate on your own bill is the only one that matters.

Your electricity
¢ / kWh

Check your bill, where it's often called the energy charge. Add any delivery charges billed per kWh, or the result will look too good.

Some energy is always lost between the wall and the battery. 90% is a reasonable estimate for home charging.

The EPA combined figure for your car. Most new EVs are between 24 and 45.

What this includes

Energy only — what it costs to move the car. We leave out charger installation (a one-off, not a running cost), battery wear, and things like insurance, maintenance and depreciation. Those matter, but they belong in their own calculation rather than hidden in this one.

If you charge on public networks, expect to pay more than this. Fast charging often costs several times the home rate.
