Work out how much fuel a trip will cost from the distance, your car's economy and the petrol price.
This free fuel cost calculator estimates how much petrol or diesel a trip will cost. It multiplies your distance by your car's fuel economy (litres per 100km) to find the fuel used, then multiplies by the price per litre. Choose one-way or return for the total trip.
This is general information only. Real fuel use varies with driving style, traffic, load and conditions. It does not include tolls, parking or vehicle wear.
Fuel is one of the biggest running costs of car ownership in Australia, especially for outer-suburban and regional drivers with long commutes. This calculator combines three things — the distance you drive, your car's fuel consumption in litres per 100 km, and the price you pay per litre — to show what a trip, a week or a year of driving actually costs.
As a worked example: a 40 km daily round-trip commute in a car that uses 8 L/100 km, with fuel at $2.00 a litre, costs about $6.40 a day — roughly $32 a work week and over $1,600 a year. Small changes to any of the three inputs move the annual figure noticeably.
If you want to cut the number down, the levers are consumption and price. Keeping tyres at the right pressure, removing roof racks you are not using and driving smoothly all reduce litres per 100 km, while timing purchases against the petrol price cycle in capital cities and using fuel price apps helps on the price side.
