What the numbers tell us

Enable JavaScript to calculate with your own values.

Why it works

consumption = litres / kilometres × 100; cost = litres × price

Assumptions and limits

Use comparable tank fill levels. Traffic, load, weather and measurement error affect the result. The entered price is an example.

Try a small challenge

Use 35 L over 500 km. Consumption?
A little hint

Divide litres by kilometres, then multiply by 100.
