How much fuel will a journey use and cost?
Estimate fuel required from distance and L/100 km, then calculate cost from a price per litre.
Formula: 450 × 6.5 ÷ 100 = 29.25 L; 29.25 × €1.75 = €51.19. This is an estimate based entirely on your entered average consumption and price.

02Understand it
Why this calculation works
litres = distance × L/100 km ÷ 100; cost = litres × price per litre. The calculation above updates with your own values, so the answer is never a disconnected black box.
Worked example
450 km at 6.5 L/100 km uses 29.25 L and costs €51.19 at €1.75/L.
Assumptions and edge cases
- Consumption and fuel price are estimates.
- Road, load and weather effects are not predicted.
