What This Tool Does
How to Use It
- Enter the total distance of your journey in kilometres or miles.
- Input your vehicle’s fuel consumption (litres per 100 km, or miles per gallon).
- Select the country to use average local fuel prices, or enter a custom price per litre.
- Compare petrol vs diesel costs side by side.
Worked Example: a 500 km trip
A 500 km drive in a car that uses 7 litres per 100 km, with fuel at €1.80 per litre, costs about €63 in fuel and burns 35 litres. Halve the consumption or the distance and you roughly halve the cost.
The formula is simple:
- Litres used = distance × (consumption ÷ 100) = 500 × (7 ÷ 100) = 35 litres
- Fuel cost = litres × price per litre = 35 × €1.80 = €63
| Input | Value |
|---|---|
| Distance | 500 km |
| Consumption | 7 L/100 km |
| Fuel price | €1.80 / litre |
| Fuel used | 35 litres |
| Total cost | €63 |
