How this EV vs Petrol vs Diesel comparison works
This calculator estimates running cost by combining your daily distance with the energy or fuel price and the expected real-world efficiency of each vehicle type. For petrol and diesel cars, it blends city mileage and highway mileage using your selected city driving share. For EVs, it uses electricity price and kilometers per kWh.
The result is useful when you want a practical day-to-day cost estimate before shortlisting a vehicle. It is especially helpful for commuters comparing whether an EV saves enough money over petrol or diesel for their specific routine.
What is included
- Electricity charging cost for EV driving.
- Fuel cost for petrol and diesel cars.
- City and highway mileage blending.
- Cost per kilometer, per day, per month, and per year.
What is not included
- Vehicle purchase price and financing cost.
- Insurance, maintenance, and tyre replacement.
- Charging losses, tolls, or parking cost.
- Battery replacement or resale value assumptions.
Helpful tips
- Use your local electricity tariff, not a national average, for the most useful EV estimate.
- Keep city mileage a little conservative if your commute includes traffic, signals, and short trips.
- For highway-heavy usage, fuel cars can look more efficient, so the city-share input matters a lot.
- Compare this running cost with your expected yearly distance before making a purchase decision.
