Start with base floor area from room dimensions or direct square footage. The calculator adds a waste allowance and then divides by coverage per box to estimate how many boxes you need.
Coverage can come directly from product packaging or be calculated from tile or plank size and pieces per box.
Base area = Length x Width (or entered total sq ft)
Required area = Base area x (1 + Waste% / 100)
Coverage per box = (Length in x Width in / 144) x Pieces per box
Boxes = ceil(Required area / Coverage per box), Cost = Boxes x Price per box
