Coating Scrap Cost with scrapped coated parts of 50 parts: a worked example

Suppose scrapped coated parts falls to 50 parts. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate scrap impact from coating defects using scrapped parts, part value, labor, and overhead.

The inputs for this scenario

  • Scrapped coated parts: 50 parts (the input this scenario stresses; the baseline uses 100)
  • Part value at scrap: 2.5 $ / part (held at the documented default)
  • Sorting and documentation labor: 150 $ (held at the documented default)
  • Replacement or expedite burden: 75 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total cost = quantity × unit cost + labor/downtime + overhead.
  • Total cost works out to 350 $ at these inputs, and this is the headline figure for the scenario.
  • Cost per piece works out to 7 $ / piece at these inputs.
  • Variable cost works out to 125 $ at these inputs.
  • Fixed adders works out to 225 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where scrapped coated parts sits at 100 parts and the headline result is 475 $, this scenario comes in 26.32% below the baseline at 350 $.
  • It computes total coating scrap cost as scrapped-part value plus sorting/documentation labor plus replacement or expedite burden, and divides by quantity for cost per piece. 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.

Results at a glance

  • Total cost: 350 $ (headline result)
  • Cost per piece: 7 $ / piece
  • Variable cost: 125 $
  • Fixed adders: 225 $
