About the EV Charging Cost Calculator

Charging cost depends on battery size, how much you are adding, charging losses and your tariff. Home charging on an off-peak rate is typically a quarter of the price of a rapid public charger, which is why the tariff field matters more than the car.

Also known as: ev charge cost, electric car charging price, cost to charge electric car, home charging cost.

Worked example

Using the values pre-filled in the calculator above:

  • Battery capacity = 60 kWh
  • Charge from = 20 %
  • Charge to = 80 %
  • Electricity rate per kWh = 0.09
  • Charging efficiency = 90 %
  • Charges per month = 12

the calculator returns:

  • Cost per charge: 3.6
  • Energy added to the battery: 36 kWh
  • Energy drawn from the grid: 40 kWh
  • Monthly cost: 43.2
