EV Charging Cost Per Year Calculator
Calculate your annual EV charging cost based on efficiency, electricity price and how far you drive. Compare yearly cost across all charging price tiers at a glance.
Annual charging cost
Typical yearly charging cost at common electricity prices
Annual charging cost depends mainly on electricity price, how far you drive and your vehicle's efficiency. Home charging at off peak rates produces the lowest annual cost, while relying on public fast chargers increases it significantly.
How this calculator works
This calculator estimates the total annual electricity cost of charging an EV based on how far you drive each year, how efficiently your vehicle uses electricity and the price you pay per kWh. It shows costs at every common price tier so you can compare home, public and fast charging at a glance.
Formula
Cost per 100 km = EV efficiency (kWh per 100 km) × Electricity price ($ per kWh)
Annual cost = Cost per 100 km × Annual distance ÷ 100
Worked example
EV efficiency: 16 kWh per 100 km
Electricity price: $0.30 per kWh (Home standard rate)
Annual distance: 15,000 km
16 × 0.30 = $4.80 per 100 km
$4.80 × 15,000 ÷ 100 = $720.00 per year
That works out to $60.00 per month.

Frequently asked questions
How much does it cost to charge an EV per year in Australia?
At a standard home electricity rate of $0.30 per kWh, a typical EV driving 15,000 km per year with an efficiency of 16 kWh per 100 km costs around $720.00 per year to charge. Charging at an off peak rate of $0.20 per kWh reduces that to around $480.00 per year.
How much can I save by switching to an EV?
Annual savings depend on how far you drive, the price of electricity, the price of petrol and the efficiency of both vehicles. Using typical Australian figures of 15,000 km per year, a home electricity rate of $0.30 per kWh and petrol at $2.00 per litre, an EV can save roughly $1,600 to $1,700 per year in fuel costs compared with a petrol vehicle using 8 litres per 100 km. Savings are higher if you drive more kilometres per year, charge at off peak rates or if petrol prices are elevated.
Does electricity price affect EV running cost significantly?
Yes. Electricity price is one of the two main factors that determines EV running cost, along with vehicle efficiency. Charging at an EV off peak rate of $0.08 per kWh instead of a standard rate of $0.30 per kWh can reduce fuel cost by around 70 percent. On the other hand, relying heavily on public DC fast chargers at $0.65 per kWh or more can significantly reduce or eliminate the cost advantage over petrol for some vehicles.
Does how I charge affect my EV running cost?
Yes, significantly. The electricity price you pay depends on when and where you charge. Charging at home overnight on an off peak tariff is usually the cheapest option. Public AC chargers are more expensive. DC fast chargers are the most expensive per kWh and can sometimes cost more per kilometre than petrol if used exclusively. Most EV owners minimise running cost by doing the majority of their charging at home and reserving public fast charging for occasional longer trips.
