A simple formula to calculate your EV charging cost — and how it compares with petrol.
The cost of charging is simple: energy added (kWh) × price per kWh.
Example
A car with a 40 kWh battery charging from 20% to 80% adds about 24 kWh. At a home tariff of ₹8/kWh that is about ₹192; at a public DC charger at ₹22/kWh it is about ₹528.
Most compact electric SUVs travel 6–7 km per kWh in city driving, so 24 kWh gives roughly 150 km. That works out to about ₹1.3 per km at home and ₹3.5 per km at a fast charger — compared with ₹6–7 per km for a petrol car.
Tips to save more
- Charge at home or work for daily use
- Use fast chargers for trips and top-ups
- Check if your electricity board offers a lower EV or time-of-day tariff
- Pre-cool the cabin while plugged in
