EV vs Petrol Calculator
Compare the long-term cost of electric and petrol vehicles in Australia.
Electric vehicles cost more upfront but far less to run. This calculator compares the total cost of ownership — purchase price plus fuel over time — using real Australian electricity rates and fuel prices by state. Select your models, enter your annual kilometres, and find out exactly when (and if) an EV pays off.

Frequently Asked Questions
Is buying an EV worth it in Australia?⌄
Whether an EV is worth it depends on your annual kilometres, state electricity rate, and the price premium over a comparable petrol car. Australians driving 15,000+ km/year typically break even within 5–8 years. In states with lower electricity rates like ACT (21¢/kWh) and QLD (25¢/kWh), EVs reach break-even faster.
How much does it cost to charge an EV in Australia?⌄
Home charging costs between $3.50–$7 per 100 km depending on your state's electricity rate and the EV's energy consumption. Compared to a petrol car that costs $14–$20 per 100 km at current fuel prices, home EV charging offers significant running cost savings.
Which Australian state has the cheapest electricity for EV charging?⌄
ACT has the lowest electricity rate at approximately 21¢/kWh, followed by Queensland at around 25¢/kWh. South Australia has the highest residential rate at approximately 35¢/kWh, which reduces the cost advantage of EV ownership compared to other states.
How many kilometres do I need to drive for an EV to be worthwhile?⌄
Generally, the more you drive, the faster an EV pays off. Drivers covering 15,000–20,000 km/year in a mid-range EV typically see break-even within 6–9 years. Drivers under 10,000 km/year may find the break-even extends beyond 10 years depending on the price premium.
What is the EV break-even year?⌄
The break-even year is when your cumulative fuel and running cost savings from the EV equal the higher purchase price paid compared to an equivalent petrol car. After this point, every kilometre driven puts you ahead financially. Use this calculator to find your specific break-even year.
