Appliance Control Board Scrap Cost Calculator at 72% scrap cost captured in estimate: a worked example

This worked example runs the appliance control board scrap cost calculator numbers for a tougher week than the baseline: 72% scrap cost captured in estimate instead of the typical 100%. Estimate scrap cost for appliance control boards from scrapped boards, cost per board, scrap capture rate, and fixed disposition cost.

The inputs for this scenario

  • Control boards scrapped: 135 boards (held at the documented default)
  • Cost per scrapped board: 22.4 $ / board (held at the documented default)
  • Scrap cost captured in estimate: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed disposition or failure analysis cost: 500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable scrap cost = control boards scrapped × cost per scrapped board × scrap cost captured in estimate.
  • Total control board scrap cost works out to 2,677 $ at these inputs, and this is the headline figure for the scenario.
  • Cost per scrapped board works out to 19.83 $ / board at these inputs.
  • Variable scrap cost works out to 2,177 $ at these inputs.
  • Fixed disposition or failure analysis cost works out to 500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where scrap cost captured in estimate sits at 100% and the headline result is 3,524 $, this scenario comes in 24.03% below the baseline at 2,677 $.
  • Use it for monthly COPQ tracking, prioritizing which defect modes to attack first, or justifying a process-improvement project. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total control board scrap cost: 2,677 $ (headline result)
  • Cost per scrapped board: 19.83 $ / board
  • Variable scrap cost: 2,177 $
  • Fixed disposition or failure analysis cost: 500 $
