What does this tool do?
Flooring is bought by the box, and cuts waste material. This calculator adds a waste allowance to the room area, converts it into boxes and estimates material cost.
The Formula
Boxes = ⌈Length × Width × (1 + Waste) ÷ Coverage per box⌉; Cost = Area with waste × PriceFrequently Asked Questions
How much flooring waste should I allow?
Ten percent is standard for a straight installation. Add more for diagonal layouts, herringbone patterns, small rooms or multiple rooms with different orientations.
Do I order by area or by box?
Order whole boxes. Multiply the boxes by the coverage per box to confirm you are buying slightly more than the area with waste.
