Coil Scrap Cost at 110% scrap cost charged to this scope: a worked example

Push scrap cost charged to this scope up to 110% and the picture changes. This example computes every intermediate figure at that operating point. Use it when operations, quality, or supplier teams need to quantify evaporator, condenser, hot water, or recovery coil losses during receiving, assembly, or final test.

The inputs for this scenario

  • Scrapped heat pump coils: 14 coils (unchanged)
  • Replacement cost per coil: 950 $ / coil (unchanged)
  • Scrap cost charged to this scope: 110 % (raised for this scenario; the documented default is 100)
  • Fixed scrap handling and disposition cost: 800 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable coil scrap cost = scrapped heat pump coils × replacement cost per coil × scrap cost charged to this scope) to the inputs above produces each figure below.
  • At this operating point the engine returns 15,430 $ for total coil scrap cost, the number this scenario is built around.
  • At this operating point the engine returns 1,102 $ / coil for replacement cost per coil.
  • At this operating point the engine returns 14,630 $ for variable coil scrap cost.
  • At this operating point the engine returns 800 $ for fixed scrap handling and disposition cost.

How this compares with the baseline

  • Against the tool's baseline example, where scrap cost charged to this scope sits at 100% and the headline result is 14,100 $, this scenario comes in 9.43% above the baseline at 15,430 $.
  • It computes the total dollar cost of scrapped heat pump coils by multiplying coil count by replacement cost and the scope percentage, then adding fixed handling and disposition cost. 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 coil scrap cost: 15,430 $ (headline result)
  • Replacement cost per coil: 1,102 $ / coil
  • Variable coil scrap cost: 14,630 $
  • Fixed scrap handling and disposition cost: 800 $
