How do you work out the fuel cost of a trip?
To work out the fuel cost of a trip, you need three figures: the distanceyou will drive (in kilometres), your car's average consumption (in litres per 100 km) and the price of the fuel.
The formula is simple: cost = (distance ÷ 100) × consumption × price per litre. For example, a 200 km trip in a car that uses 6.5 L/100 km, with diesel at €2.186 a litre, costs about €28.42.
The calculator uses real fuel prices in Portugal, which we receive every day from the Directorate-General for Energy and Geology (DGEG). It also shows the difference between filling up at the cheapest station and at the most expensive one, so you can decide where to fill up.
Average consumption by type of car
Consumption varies a lot with the type of car: a city car uses about 5.5 L/100 km, a compact about 6.5 L/100 km, a family car about 7.5 L/100 km, an SUV about 8.5 L/100 km and a van about 9.5 L/100 km. These are rough figures: driving style, the road and maintenance change the real consumption.
