Fuel Cost Calculator
This calculator works out what fuel a trip will cost. Enter the distance you're driving, your car's fuel consumption and the price you pay per litre, and it returns the fuel cost for the journey. If you don't know what you'll pay at the pump, the default is an AIP capital-city weekly average, labelled with the week it covers, so you can get a realistic figure straight away and then adjust the inputs to match your own car and route.

Planning a specific trip? The corridor pages pre-fill road distance and cost the drive at the average price at each end (a regional town is costed at its state capital's average, since AIP reports capitals only). City prices: Sydney, Melbourne, Brisbane, Perth, Adelaide, Hobart, Canberra, Darwin.
