In New South Wales, a typical petrol car (7.5 L/100km) costs $14.17/100kmat the current bowser price. The equivalent EV (16.5 kWh/100km) charged at home costs $4.70/100km — a saving of $9.47 per 100km.
At 15,000 km/year that compounds to roughly $1,421/year in fuel savings. Over a typical 5-year ownership period: around $7,105 — enough to meaningfully offset a higher EV purchase price.
The wildcard is public fast charging: at 50–60¢/kWh the EV running cost rises to $9.08/100km — still cheaper than petrol, but the gap narrows. Apartment dwellers or frequent long-distance drivers should weigh the charging mix carefully.
