FAQ
Frequently Asked Questions
How do I calculate my actual fuel consumption?
Fill up completely, note the odometer reading, drive until near empty, fill up again and note the liters. Divide liters by kilometers driven, then multiply by 100 to get liters per 100 km.
How can I reduce my fuel consumption?
Drive at moderate speeds, shift early (around 2,000 RPM for diesel, 2,500 for gasoline), check tire pressure regularly, remove roof racks when not in use, and avoid short trips with a cold engine.
Is the EV vehicle tax exemption still active?
Yes. The 2024 Wachstumschancengesetz extended the exemption for pure electric vehicles through 31 December 2030 (previously end of 2025). EVs are exempt from vehicle tax for 10 years, at most until 31 December 2035.
Guide
Quick Answer
The fuel consumption calculator computes fuel consumption per 100 km and the fuel costs of a trip or over a period.
What is the Fuel Consumption Calculator?
The fuel consumption calculator computes fuel consumption per 100 km and the fuel costs of a trip or over a period.
How does the Fuel Consumption Calculator work?
Enter the distance driven and the fuel amount filled. The calculator determines consumption in litres per 100 km. With the current fuel price the cost per kilometre and per trip is computed.
Key Data and Facts
Average car consumption Germany: approx. 7.4 l/100 km. Petrol price 2026: approx. 1.60-1.80 euros/l. Diesel: approx. 1.50-1.70 euros/l. Eco-driving saves 10-20% fuel.
Step-by-Step Guide
How to calculate fuel consumption step by step: 1. Note the tank filling: fill up completely and note the odometer reading. 2. Next tank filling: at the next full fill-up, note the new odometer reading and the amount filled in litres. 3. Distance driven: new odometer reading minus old odometer reading. 4. Calculate consumption: (litres filled / kilometres driven) x 100 = litres per 100 km. 5. Fuel costs per km: consumption per 100 km / 100 x price per litre. 6. Costs per trip: distance x cost per km. 7. Tips for saving fuel: check tyre pressure regularly (0.3 bar above the norm saves about 3 %). Drive with anticipation, do not let the engine warm up while idling. Avoid short trips. Use the air conditioning deliberately. Eco-driving saves 10-20 % fuel.
Calculation Example
Refuelled: 45 litres, driven: 580 km. Consumption: 45 / 580 x 100 = 7.76 l/100 km. At a petrol price of 1.70 EUR/l: cost per km = 0.132 EUR. Trip of 250 km: 32.93 EUR.
