It uses your actual monthly distance, local fuel price, and electricity tariff, so the running-cost comparison is close to real numbers. Break-even estimates assume steady usage and do not include maintenance or insurance differences.

No. This calculator compares fuel and electricity running costs only. EVs typically have lower maintenance costs too, since they have fewer moving parts, no oil changes, and regenerative braking that reduces brake wear.

Use the per-unit (per kWh) rate from your latest electricity bill. If you charge at a public station instead of home, use that station’s per-kWh price, which is usually higher than home rates.

Entering both on-road prices is easier and less error-prone than calculating the price difference yourself, and it lets us show you that difference clearly alongside the break-even period.

Yes, usually significantly. Home charging uses your domestic electricity tariff, while public fast chargers in India often charge 15 to 22 rupees per unit, roughly double to triple the home rate.

In most cases yes, because electricity is far cheaper per kilometer than petrol even after accounting for typical Indian EV efficiency. The gap widens further as petrol prices rise.
