Reading the result
Payback period = (EV price − petrol price) ÷ annual fuel savings. If the EV is cheaper, payback is "immediate".
Excludes maintenance (EVs typically lower), insurance (often higher for EVs), battery degradation and resale value. Add these manually if relevant.
Real-world EV efficiency drops 10–20% in highway driving and ~30% in cold weather.
