Home/Automotive/EV Charging Cost Calculator

EV Charging Cost Calculator

-cost of this charge
-energy added to battery
-range added
-cost per mile

Work out what it costs to charge your electric car at home or on the road. Enter your battery capacity in kilowatt hours, the starting and target charge percentages, and your electricity price per kilowatt hour, and this calculator returns the cost of that charge along with the energy added. Because chargers lose a little energy as heat, you can add a charging efficiency figure to get a more realistic bill, since you pay for what comes out of the wall rather than what lands in the battery. It also estimates the cost per mile if you enter your efficiency, which is the fairest way to compare an EV against a gas car. Home charging is usually far cheaper than public fast charging, and this tool makes the gap clear. Everything runs in your browser.

How to use EV Charging Cost Calculator

  1. Enter the battery size and the charge level you want to add.
  2. Enter charging losses and your electricity price per kWh.
  3. Read the charging cost.

Frequently asked questions

How is EV charging cost calculated?

It finds the energy needed from the battery size and the charge you add, adjusts for charging losses, then multiplies by your electricity price per kWh.

Why include charging losses?

Some energy is lost as heat during charging, so the grid draws more kWh than the battery stores, which raises the real cost.

Can it show cost per mile?

Yes. With your efficiency it can express the charging cost as a cost per mile driven.
