The EV charging cost calculator shows how much a single charge costs based on battery size, electricity price and the share you charge. It also estimates the cost per hundred kilometres, making the price of driving easy to picture.
How the calculator works and what it’s for▾
How the cost is calculated
The charging cost is the energy charged multiplied by the electricity price. The energy charged is the battery size times the percentage you top up.
For example, charging a 60 kWh battery by 50% while electricity costs 20 cents per kilowatt-hour gives 30 kWh × €0.20 = €6.
What you enter and what you get
Enter the battery size in kilowatt-hours, the electricity price in cents per kilowatt-hour and the amount you want to charge as a percentage.
You see the energy charged, the total cost of the charge and an estimate of the cost per hundred kilometres at roughly 18 kWh consumption.
Who finds it useful
The calculator suits EV owners and prospective buyers who want to compare the cost of home charging with public charging points.
It makes it easy to see how swings in electricity prices affect monthly driving costs and whether to schedule charging for cheaper hours.
Good to know
Home charging is usually the cheapest option, whereas fast charging costs noticeably more per kilowatt-hour.
The calculator uses the price you enter and does not account for small charging losses, so real consumption may be a touch higher.
