Live result$1,794.00/yearPetrol $2,550.00/year; EV $756.00/year; EV premium payback 2.8 years.

Formula used

Petrol annual cost = annual km / 100 x L/100km x fuel price. EV annual cost = annual km / 100 x kWh/100km x electricity price. Saving = petrol cost - EV cost. Payback = EV premium / annual saving.

This is the method behind the answer, so the result can be checked rather than simply trusted.

Petrol annual cost = annual km / 100 x L/100km x fuel price. EV annual cost = annual km / 100 x kWh/100km x electricity price. Saving = petrol cost - EV cost. Payback = EV premium / annual saving.

At 15,000 km, 8.5 L/100km and $2/L, petrol costs $2,550/year. At 18 kWh/100km and $0.28/kWh, EV electricity costs $756/year.
