How is fuel cost calculated?

Divide the distance by your mileage to get the litres used, then multiply by the price per litre:

Fuel (L) = distance (km) ÷ mileage (km/L)

Cost = fuel (L) × price (₹/L)

Cost per km = price ÷ mileage

Use your real-world mileage

Company-claimed (ARAI) mileage is measured in ideal test conditions. Real highway mileage is often 10–20% lower, and city mileage lower still. Use the figure from your own fill-ups for the best estimate (our Mileage Calculator can work it out).

CNG and EVs

For CNG, enter mileage in km per kg and the price per kg; the maths is the same. For an electric car, use our Electricity Bill Calculator with the car's kWh per 100 km.

Frequently asked questions

How do I calculate the petrol cost for a trip?

Divide the distance by your car's mileage and multiply by the petrol price. 350 km at 15 km/L and ₹103/L costs about ₹2,403.

What is cost per km?

Fuel price ÷ mileage. At ₹103/L and 15 km/L, each km costs about ₹6.87 in fuel.

Does this include tolls and parking?

No, only fuel. Add tolls (FASTag), parking and driver charges separately.

How do I calculate the petrol cost of my bike?

Distance ÷ your bike's mileage × the petrol price. Riding 30 km a day on a 50 km/L bike at ₹103 per litre costs about ₹62 a day.
