Flooring Cost Calculator

Estimate net/buy area, piece count, boxes, and material / install / underlay costs from room size, layout waste and plank specs.

How to use

1. Enter room length & width; deduct non-floor areas if any
2. Pick a layout (straight / diagonal / herringbone / parquet) or set waste %
3. Enter plank size, pcs per box, and optional unit prices

Formulas

• Net area = L × W − deduct
• Buy area = net × (1 + waste%)
• Pieces = ceil(buy area ÷ plank area); boxes = ceil(pieces ÷ pcs/box)

Typical waste: straight 3–5%, diagonal ~8%, herringbone ~10%. Buy from the same dye lot; calculations run locally in your browser.
