Cost to charge the EV for this distance

As some energy is lost during the charging process, it would be unrealistic to use a charging efficiency of 100%. It depends on the electric vehicle model, but the charging efficiency is generally somewhere between 80% and 90%, sometimes less in some cases. Actually, the lower the battery charging efficiency is, the higher the charging cost is going to be. See the example in the table below:

Vehicle Battery Size33kWh33kWh
Charging efficiency90%80%
Electricity price0.15 cent/kWh0.15 cent/kWh
Charging cost5.50 $6.19 $

If you have some difficulties using our calculator, we’ve created a step-by-step guide to assist you during the calculation.

Guide to use our electric car charging cost calculator

  • Select your currency
  • Electricity price of your supplier (price/kWh) – Select your electricity rate per kWh. Check your electricity bill or contact your supplier to find this information.
  • The battery size of the EV – It corresponds to the full battery capacity of the car in kWh.
  • Charging efficiency – Enter the charging efficiency of the vehicle in percentage.

Good job! You’ve now calculated the cost to fully charge the electric vehicle.

If you’re interested in estimating the cost to charge an EV for a certain distance, please follow the next steps.

  • EV energy consumption per 100 miles or km – Select here the consumption in kWh/100 of the vehicle.
  • Distance – Select the distance you want to calculate the charging cost for.

This is a basic estimation simply taking into account the price you pay per kWh of electricity, the battery size of the vehicle, the energy consumption, and the charging efficiency. However, many other factors can influence the charging price of an electric vehicle.
