How it works

You pay for whole boxes, so the cost uses the area you actually buy.

The formula

  • Needed = area × (1 + extra %)
  • Boxes = ⌈needed ÷ coverage per box⌉
  • Cost = boxes × coverage per box × price per sq ft

How to use this calculator

  1. Measure floor area.
  2. Choose extra (more for diagonal layouts).
  3. Enter box coverage and price.
