Power Electronics Scrap Cost at 58% share of unit cost recognized as scrap: a worked example

Suppose share of unit cost recognized as scrap 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 scrap cost for power modules, inverter boards, drives, converters, or motor electronics from scrap count, cost per unit, affected share, and fixed containment cost.

The inputs for this scenario

  • Scrapped power electronics units: 100 units (held at the documented default)
  • Cost per scrapped unit: 45 $ / unit (held at the documented default)
  • Share of unit cost recognized as scrap: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed scrap containment and disposal cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable power electronics scrap cost = scrapped units × cost per scrapped unit × scrap exposure captured.
  • Total power electronics scrap cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Scrap cost per affected unit works out to 28.6 $ / piece at these inputs.
  • Variable power electronics scrap cost works out to 2,610 $ at these inputs.
  • Fixed scrap containment cost works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of unit cost recognized as scrap sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • It totals scrap dollars by combining scrapped units times unit cost times the recognized share, plus a fixed containment cost. 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.
