Estimate the fuel cost of a trip from distance, vehicle mileage and fuel price, and split it between passengers.
Fuel needed = distance ÷ mileage; cost = fuel needed × price per litre. A 500 km trip at 15 km/L and ₹100 a litre uses 33.3 litres and costs ₹3,333 — about ₹833 each for four people.
The Fuel Cost Calculator estimates how much fuel a trip needs and what it will cost. Enter the distance, your vehicle's fuel economy (in km/L, L/100 km or mpg) and the fuel price, and it returns the litres required and the total cost. A round-trip option doubles the distance, and a passenger count splits the bill.
It works for petrol, diesel and CNG (use the right price unit) and is useful for road-trip budgeting, comparing car and train costs, and sharing costs on a carpool. Find your mileage with the Gas Mileage Calculator and the distance with the Mileage Calculator.
The calculation converts your inputs into kilometres, litres and a price per litre.
| Trip | Fuel cost |
|---|---|
| 500 km, 15 km/L, ₹100/L, shared by 4 | 3,333.33 total — 833.33 each |
| 100 km round trip, 8 L/100 km, ₹100/L | 1,600 |
| 100 miles, 30 mpg (US), $4/gallon | 13.33 |
Divide the distance by your vehicle's km/L to get litres needed, then multiply by the price per litre.
At 15 km/L you need 33.3 litres; at 20 km/L, 25 litres. Enter your own mileage for an exact figure.
Yes. Choose the unit next to the fuel economy box and the calculator converts it.
Tick “Round trip” to double the distance before calculating.
Enter the number of people sharing the cost and the calculator shows the cost per person.
Yes — enter the fuel's price per litre (or per kg for CNG, using your km/kg mileage as the economy figure).
Choose “per US gallon” or “per UK gallon” and the calculator converts it to a price per litre.
No. Add tolls and parking to the result yourself.
It is as accurate as your mileage figure. City traffic, AC use and loads can lower the real mileage.
