EV Charging Cost Per Month Calculator
Calculate your monthly EV charging cost based on efficiency, electricity price and how far you drive. Compare monthly cost across all charging price tiers at a glance.

Typical monthly EV charging cost in Australia
Monthly 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 monthly cost, while relying on public fast chargers increases it significantly.
How this calculator works
This calculator estimates how much you spend charging your electric vehicle each month. It uses your annual driving distance, vehicle efficiency and electricity price to calculate a monthly charging cost. 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)
Monthly cost = Cost per 100 km × Annual distance ÷ 100 ÷ 12
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 ÷ 12 = $60.00 per month
That works out to $720.00 per year.

Frequently asked questions
How much does it cost to charge an EV per month?
At a standard home electricity rate of $0.30 per kWh and a typical EV efficiency of 16 kWh per 100 km, driving 15,000 km per year costs around $60 per month in electricity. The actual amount depends on how far you drive, your vehicle's efficiency and the electricity price you pay.
Is home charging cheaper than public charging?
Charging at home using a residential electricity tariff is typically much cheaper than public charging. Public charging includes the cost of installing, maintaining and operating charging infrastructure, which increases the price compared with home electricity. Because of this, most EV owners do the majority of their charging at home and use public chargers mainly for convenience or long distance travel.
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. This is why charging behaviour has a large impact on the true running cost of an EV.
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.
