How it works
Estimate trip fuel cost from distance, consumption and litre price. This free estimate is for planning purposes. Verify financial and tax decisions with a qualified professional.
How trip fuel cost is estimated
The calculator multiplies distance by consumption per 100 km, then by the price per litre: cost = (distance × consumption ÷ 100) × price per litre.
Why consumption is per 100 km
Fuel economy is commonly expressed as litres used per 100 km driven, so the distance is scaled by that ratio before pricing.
Round trips
Double the distance value for a round trip, or enter the full round-trip distance directly.
