How it works

In US units the fuel used is the distance divided by the miles per gallon, and the cost is the fuel used times the price per gallon. In metric units the fuel used is the distance divided by 100 and multiplied by the litres per 100 km, times the price per litre.

How to use the Fuel Cost Calculator

Enter the values requested by the tool and start with one realistic example. Read the result together with its unit or label, then change one input at a time if you want to compare options. Keeping a note of the original figures makes the calculation easier to check later.

Use the estimate as a practical guide and check the original bill, product information or terms when an exact figure matters.
