Gypsum, Drywall & Interior Panel Manufacturing worked example

Defect Cost at 58% quality cost capture rate: a worked example in gypsum, drywall & interior panel manufacturing

Suppose quality cost capture rate falls to 58%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate total defect cost for a board production run by combining defective board count, rework or scrap cost per board, quality cost capture rate, and fixed quality overhead.

The inputs for this scenario

  • Defective boards: 100 boards (held at the documented default)
  • Rework or scrap cost per board: 45 $ / board (held at the documented default)
  • Quality cost capture rate: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed quality overhead: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable defect cost = defective boards x rework or scrap cost per board x quality cost capture rate.
  • Weighted cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Per piece value works out to 28.6 $ / piece at these inputs.
  • Captured value works out to 2,610 $ at these inputs.
  • Fixed adjustment works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where quality cost capture rate sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • It multiplies defective boards by per-board rework or scrap cost and a capture rate for variable cost, then adds fixed quality overhead for a total dollar figure. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
