Winding Scrap Cost at 92% share charged to this line or period: a worked example

This scenario runs the winding scrap cost calculation on the strong side: 92% share charged to this line or period, with every other input held at its documented default. Use it when winding scrap is going through a weighted-cost review and you need a defensible loss figure for the line or period.

The inputs for this scenario

  • Scrapped windings: 100 windings (unchanged)
  • Cost per scrapped winding: 45 $ / winding (unchanged)
  • Share charged to this line or period: 92 % (raised for this scenario; the documented default is 80)
  • Fixed containment cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable winding scrap cost = scrapped windings × cost per scrapped winding × share charged to this line or period) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total winding scrap cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for scrap cost per winding.
  • At this operating point the engine returns 4,140 $ for variable winding scrap cost.
  • At this operating point the engine returns 250 $ for fixed containment cost.

How this compares with the baseline

  • Against the tool's baseline example, where share charged to this line or period sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • Use it when building a yield-improvement business case, allocating scrap to a line or month, or quantifying the cost of a winding defect spike. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total winding scrap cost: 4,390 $ (headline result)
