Context & Reference

How it works

Calculators are most useful when their assumptions are clear. Review these details to better understand the logic behind the results.

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.
