Useful context
How it works
Use the calculator first, then scan the details below when you want more context about the inputs, result, or assumptions.
How to use it
Enter the trip distance, choose an efficiency unit, enter efficiency and fuel price, then review litres and cost.
Understand the result
Fuel used is the estimated volume for the trip; trip cost multiplies that volume by the entered price.
Example
A 300 km trip at 7 L/100 km uses about 21 litres.
Notes
The estimate assumes steady efficiency and one-way distance. Traffic, terrain, load, and return trips change real usage.
