Step by step
The formula
cost = (distance ÷ economy) × price
Trip cost is fuel consumed multiplied by fuel price. Real consumption varies with speed, load, terrain and driving style — motorway cruising is typically far more efficient than stop-start city traffic, so treat the figure as a planning estimate.
