How to calculate
Estimate fuel and cost for a road trip.
Litres = distance × consumption ÷ 100; cost = litres × price
Worked example
Trip distance (km): 300; Consumption (L/100 km): 7; Fuel price per litre: 2.
Estimated fuel cost: 42 ; Fuel needed: 21 L.
Assumptions and limits
Uses your vehicle consumption estimate. Driving conditions can change actual use.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
Fuel needed is distance multiplied by consumption per 100 kilometres. Estimated cost multiplies that fuel by your price per litre.
When this tool is useful
Budget fuel for a trip using your expected distance and vehicle consumption.

Frequently asked questions
Do I enter kilometres per litre?
No. This tool expects litres per 100 kilometres. To convert km/L, divide 100 by that value.
Does the result include tolls or parking?
No. It covers fuel only. Add other travel costs separately.
