How to use it

Choose kilometres with litres per 100 km, or miles with US miles per gallon. Then enter trip distance, fuel consumption and the price per matching fuel unit.

A worked example

A 300 km trip at 7 L/100 km uses 21 litres. At 1.50 per litre, the estimated fuel cost is 31.50.

What to know

Miles-per-gallon mode uses US gallons, not imperial gallons. The result excludes tolls, parking and other trip costs. Real fuel consumption varies with route, vehicle and driving conditions.
