Resale assumes EV depreciates faster than petrol (battery & tech). Service estimate is conservative — EVs need ~35% of petrol service costs.
What this calculator captures (and doesn’t)
Includes
Purchase price, fuel/electricity, scheduled service costs, and a realistic resale value at the end of your ownership period.
Doesn’t include
Insurance differences, road tax, government incentives, charger installation costs, or unscheduled repairs. EV battery replacement is rare in 5 years.
When EVs win
Higher annual driving (15,000+ km/yr), cheap home charging electricity, and government EV subsidies tip the balance heavily toward EV.
Service your existing car at the right intervals
Whether you upgrade or stick with petrol, regular service protects resale value.
