EV home charging cost calculator

Cost per full charge = Battery kWh ÷ charger efficiency × home tariff. Real-world charging losses are typically 10–15% (slow AC at home is more efficient than fast DC at a station).

Compare with petrol

Plug those per-km numbers into our EV vs petrol calculator to see how the running cost stacks up. Typical petrol: ₹6–8 per km. Typical EV home-charging: ₹1.5–2 per km. The math usually favours EVs heavily on running cost — the question is whether the upfront price gap pays back over your ownership period.
