Fuel Cost Calculator
Work out what a journey costs in fuel, or what your daily commute adds up to over a month — and what each person pays when you share the ride.
Total fuel cost

500 km
Fuel needed
27.8 litres
Cost per km

A 500 km journey needs 27.8 litres and costs ₹2,917.
Fuel only — tolls, parking, servicing and depreciation are not included. Real-world mileage is typically 10 to 20% below the manufacturer figure, and worse in city traffic, so use what your vehicle actually delivers rather than the brochure number.
Frequently Asked Questions
How is fuel cost calculated?
Distance divided by mileage gives the litres needed, multiplied by the price per litre. A 500 km trip at 18 km/l with petrol at ₹105 needs 27.8 litres and costs about ₹2,917.
What mileage figure should I use?
Whatever your vehicle actually delivers, not the brochure number. Real-world mileage typically runs 10 to 20% below the claimed figure, and city driving can be far worse than highway driving.
Does this include other running costs?
No, fuel only. Tolls, parking, servicing, tyres, insurance and depreciation are all excluded — including them roughly doubles the true cost per kilometre for most cars.
How do I compare against a cab or train?
Use the cost per kilometre figure. Remember that a cab fare covers the driver, vehicle and all running costs, so comparing it against fuel alone understates the true cost of driving yourself.
