Trip Fuel Cost Calculator

How it is calculated

The tool first converts distance and consumption into fuel volume, then multiplies by the price: Fuel = Distance / 100 × Consumption and Cost = Fuel × Price. Distance is in kilometres, consumption in litres per 100 km, and price per litre. The fuel volume is shown in litres and the cost in dollars, both rounded to two decimals. Zero is accepted, but a negative or empty field gives no result. The tool assumes the same consumption for the whole trip; it does not add tolls, parking or wear.

Common mistakes

• Entering miles per gallon in the consumption field. The field expects litres per 100 km, where a smaller number means a more efficient car.
• Entering the distance in miles while consumption is per 100 km.
• Using the manufacturer's best-case consumption; motorway speed, a loaded car or air conditioning raise real use.
• Forgetting the return leg and entering only the one-way distance.
• Entering the price per gallon or per 100 litres instead of per litre.
