The short answer

Electric (EV) costs ₹4 less per kilometre to run than diesel — about ₹43,333 a year at 1,000 km a month. But it costs roughly ₹2,70,000 more to buy, so you need about 74,769 km — roughly 6.2 years of average driving — before you are actually ahead.

Diesel

18 km/L · ₹89/L
₹5 / km

Better mileage and torque, but higher purchase premium, costlier servicing, and a 10-year NGT age cap in Delhi-NCR.

Electric (EV)

6 km/kWh · ₹8/kWh
₹1 / km

Lowest running cost by far when charged at home, near-zero servicing — but the highest purchase premium and charging access is the real constraint.

How long until electric (ev) pays back

If you driveBreak-even takes
500 km/month 12.5 years
1,000 km/month 6.2 years
1,500 km/month 4.2 years
2,500 km/month 2.5 years

Break-even = the ₹2,70,000 purchase premium divided by the ₹4/km running-cost saving. If you plan to keep the car less time than this, the cheaper-to-buy option wins.
