Fuel cost 16Show steps
- Fuel used: 100 km ÷ 100 × 8 L/100km = 8 L.
- Cost: 8 L × 2 = 16.
How to use the fuel cost calculator
- 1Enter the trip distance in kilometres.
- 2Enter your car’s fuel consumption in litres per 100 km (petrol cars typically use 6–9).
- 3Enter the price per litre, then read the fuel cost — with the litres burned under Show steps.
Currency-neutral by design
The calculator carries no currency symbol — enter the price per litrein whatever currency you pay, and the cost comes back in that same currency. Litres burned = distance ÷ 100 × consumption, so halving your consumption halves the fuel bill.
Frequently asked questions
How is the fuel cost calculated?
First the litres the trip uses: distance ÷ 100 × consumption (in L/100km). Then multiply by the price per litre. A 100 km trip at 8 L/100km and a price of 2 uses 8 litres and costs 16.
What is a typical fuel consumption figure?
Most petrol cars use 6–9 L/100km, small diesels 4–6, and larger SUVs 9–13. Use your car's on-board average for the most accurate result.
Does the currency matter?
No. The calculator is currency-neutral — enter the price per litre in any currency and the fuel cost comes out in that same currency.
