How this fuel cost calculator works
- Cost per km - each fuel’s price divided by its efficiency (₹/litre ÷ km/litre, ₹/kg ÷ km/kg, ₹/kWh ÷ km/kWh).
- Daily · monthly · yearly - your distance × cost per km, scaled by 30 (month) and 360 (year).
- Cheapest - the lowest running cost is highlighted, with your yearly saving versus the other fuels.
Prices and efficiencies are indicative defaults for India and fully editable. Running cost only - this does not include the car’s price, insurance or maintenance. For reference, not a quote.
Fuel cost - FAQs
How is the fuel cost calculated?+−
For each fuel it is running cost per km × your distance. Cost per km = price ÷ efficiency - so ₹/litre ÷ km/litre for petrol, ₹/kg ÷ km/kg for CNG, and ₹/kWh ÷ km/kWh for an EV. Daily is your distance × cost/km; monthly is × 30 and yearly is × 360.
Does this depend on which car I pick?+−
No - this calculator is deliberately car-independent. You enter your own efficiency and local fuel price for each option, so it works for any vehicle. For a car-specific comparison with purchase price and break-even, use the EV vs Petrol cost-of-ownership calculator.
Where do the default prices come from?+−
The defaults are indicative retail rates for New Delhi and are fully editable - enter your city’s petrol/CNG rate and electricity tariff for an accurate result.
