Fuel Cost Calculator

What the Fuel Cost Calculator does

This tool tells you how much a journey will cost in fuel and how many litres you will use to get there. Instead of guessing or doing the arithmetic in your head, you enter three simple numbers and read the answer straight away. It helps commuters comparing routes, road trippers planning a budget, delivery drivers tracking expenses, and anyone splitting petrol money with passengers. Knowing the figure up front makes it easier to decide whether a trip is worth the cost or how much to set aside for the tank.

How to use it

1. In Distance (km), type how far you plan to drive in kilometres.
2. In Consumption (L/100km), enter how many litres your vehicle uses per 100 km, which you can usually find in the manual or on the trip computer.
3. In Fuel price (per L), type the price of one litre at the pump.
4. Read the results: the total fuel cost for the trip and the litres of fuel needed to cover the distance.

A worked example

Say you are driving 300 km in a car that uses 7 L/100km, with fuel priced at 1.8 per litre. The calculator works out that you need 21 litres and that the trip costs 37.80. Change any field to test other cases, for example a cheaper pump price or a longer route, and the figures update instantly.
