EV vs Petrol Savings Calculator
Compare annual fuel cost against EV electricity cost for the same mileage. This is useful when deciding whether an EV fits your driving pattern.
EV cost = annual miles / miles per kWh x electricity price. Fuel cost = annual miles / MPG x 4.54609 x price per litre.
When EV savings look strongest
EVs often look strongest where most charging happens at home on a lower tariff and annual mileage is high enough to matter.
When savings shrink
If you rely heavily on public rapid charging or drive very few miles, fuel savings may be less important than purchase price and insurance.
