How we forecast
FuelRadar has helped Australian drivers find cheaper fuel since 2020. Each estimate starts from Perth's reported daily city averages and how they have moved recently. A city daily average is FuelRadar's scheduled morning average of the city's reported station prices, the figure this page quotes for every capital. Where a city has a regular price cycle, the estimate projects that cycle; elsewhere it follows the recent trend, blended with the latest dated wholesale price change. The likely range widens with each day ahead.
Next-day estimates missed by 1.5 c/L on average, closer than assuming prices stay the same (4.0 c/L).
