How to calculate it
Budget-first flooring tool: area, waste, coverage per box and your price per box. Use the Flooring Calculator when you are still measuring the room and only need a box count.
Source: Boxes = total area with waste ÷ coverage per box; cost = boxes × price per box. Box coverage (ft²) is printed on the label.
200 ft² with 10% waste = 220 ft² ÷ 20 ft² per box = 11 boxes × $45 = $495 estimated material cost.
