Fuel Cost Calculator

Fuel Cost Calculator – Calculate fuel costs per trip & per 100 km
Our free fuel cost calculator helps you determine how much a trip really costs – per kilometre, per 100 km or for a complete journey. Simply enter your average consumption, fuel price and distance to compare different cars or driving styles.
FAQ: Frequently asked questions about fuel consumption & fuel costs
How does the fuel cost calculator work?
The calculator uses your average fuel consumption (e.g. in l/100 km), the current fuel price per litre and the selected distance. From this it calculates your fuel costs per trip, per 100 km and per kilometre, so you can instantly see the true cost of commuting, daily driving or long trips.
Why is my real fuel consumption higher than the official figures?
Official consumption values are measured under ideal test conditions. In real life, short trips, stop-and-go traffic, heavy load, driving style, tyre pressure and weather all increase fuel consumption. Our calculator therefore works best with your real-world average, for example from your on-board computer or a fuel log.
Can I compare different cars with the fuel cost calculator?
Yes. By entering different consumption values one after another you can easily compare several vehicles. This shows you whether a more efficient petrol car, a diesel, hybrid or electric vehicle could save you money in the long run.
How do speed and driving style influence my fuel costs?
High speed, hard acceleration and late braking significantly increase fuel use. Driving just 10–20 km/h slower on the motorway can save several litres per 100 km. Use the calculator to estimate how a smoother driving style or lower cruising speed affects your overall fuel costs.
How often should I recalculate my fuel costs?
It is a good idea to update your calculation whenever fuel prices change significantly or your driving profile is different – for example after changing car, moving house or starting a new commute.
Can I use the calculator for holiday trips and long-distance journeys?
Absolutely. Simply enter the total distance of your trip and the calculator shows you the expected fuel costs. You can also test how an alternative route, vehicle or speed would change your budget.
