EV vs Petrol Cost Calculator (Singapore, 2026)

This model answers: “At my mileage, is an EV cheaper than a petrol car — and when does it break even?” It’s a planning model (good for first-pass decisions). Real ownership varies by COE cycle, insurance, charging access, and resale.

Inputs

Annual mileage (km/year)

Holding period (years)

Petrol efficiency (km/L)

Electricity price (SGD/kWh)

EV upfront premium vs petrol (SGD)

EV road tax difference (EV − petrol, SGD/year)

EV maintenance difference (EV − petrol, SGD/year)

Resale difference at end (EV − petrol, SGD)
