Assumptions
- Fuel price should be checked for the region you'll be driving through as it varies daily.
- Does not account for terrain, load or driving style, which affect real consumption.
How this calculator works
This calculator multiplies your trip distance by your vehicle's fuel consumption rate and the price per litre to estimate total fuel cost. Use it to compare routes or vehicles before a long drive.
Frequently asked questions
Where do I find my car's fuel consumption?
Check your vehicle's fuel label or owner's manual for the combined L/100km figure, or calculate it from a recent full tank of fuel.
Does this include tolls or other running costs?
No, this only estimates fuel. Use the Road Trip Cost calculator to add accommodation, food and tolls.
How accurate is the fuel price I should use?
Fuel prices vary by region and change daily, so check a current price for the areas you'll be driving through, such as via state fuel price apps.
