Fuel Cost Calculator

Calculate the fuel needed and the cost of a trip from distance, fuel consumption and fuel price.

Formula

Fuel = Distance × Consumption ÷ 100. Cost = Fuel × Price per liter.

About this calculator

Enter consumption in liters per 100 km. If you know your car's figure in mpg or km/L, convert it first with the fuel economy converter.

Amounts are shown without a currency symbol, so the calculator works for any currency: enter all values in the same one.

Frequently asked questions

Why is my real consumption higher than the official figure?

Official figures come from laboratory test cycles. Traffic, speed, air conditioning, load and tyre pressure all raise real-world consumption.
