How this works

An EV usually has a higher sticker price but a much lower running cost. We compare your EV cost per km (electricity rate ÷ km-per-unit) against your petrol cost per km (petrol price ÷ mileage). The monthly saving is the difference × your monthly distance. The breakeven point is the extra EV price ÷ monthly saving. Battery degradation, servicing and resale are not included — this is a running-cost estimate to guide the decision.
