Fenestration Scrap Cost at 110% scrap cost scope included: a worked example

Push scrap cost scope included up to 110% and the picture changes. This example computes every intermediate figure at that operating point. prioritizing scrap reduction in window, door, or construction-product production

The inputs for this scenario

  • scrapped lites, units, or components: 42 items (unchanged)
  • average cost per scrapped item: 186 $ / item (unchanged)
  • scrap cost scope included: 110 % (raised for this scenario; the documented default is 100)
  • fixed scrap containment and sorting cost: 1,200 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable fenestration scrap cost = scrapped lites, units, or components × average cost per scrapped item × scrap cost scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 9,793 $ for total fenestration scrap cost, the number this scenario is built around.
  • At this operating point the engine returns 233 $ / piece for scrap cost per item.
  • At this operating point the engine returns 8,593 $ for variable fenestration scrap cost.
  • At this operating point the engine returns 1,200 $ for fixed scrap containment and sorting cost.

How this compares with the baseline

  • Against the tool's baseline example, where scrap cost scope included sits at 100% and the headline result is 9,012 $, this scenario comes in 8.67% above the baseline at 9,793 $.
  • It computes total fenestration scrap cost as variable scrap (items times cost per item times scope) plus a fixed containment and sorting cost, and reports cost per scrapped item. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • total fenestration scrap cost: 9,793 $ (headline result)
  • scrap cost per item: 233 $ / piece
  • variable fenestration scrap cost: 8,593 $
  • fixed scrap containment and sorting cost: 1,200 $
