Fuel Cost Comparison: Petrol vs Diesel vs CNG vs EV Running Costs

How much does it cost to run a petrol, diesel, CNG or electric car in India? We do the math on 1,000 km of driving across all fuel types.

Based on Delhi fuel prices (Nov 2024):

| Fuel | Price | Mileage | Cost/km | |---|---|---|---| | Petrol | ₹94.7/L | 15 kmpl | ₹6.31 | | Diesel | ₹89.6/L | 18 kmpl | ₹4.98 | | CNG | ₹76.6/kg | 23 km/kg | ₹3.33 | | EV (home) | ₹8/kWh | 7 km/kWh | ₹1.14 | | EV (public) | ₹20/kWh | 7 km/kWh | ₹2.86 |

- Petrol: ₹3,15,500 - Diesel: ₹2,49,000 - CNG: ₹1,66,500 - EV (home): ₹57,000 - EV (public): ₹1,43,000

An EV that costs ₹3 lakh more than a petrol car will break even in about 5 years of home charging.
