Enclosure Scrap Cost at 72% scrap cost assigned to this issue: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop scrap cost assigned to this issue to 72%, then walk the calculation through step by step. Estimate the cost of scrapped charger enclosures, pedestals, doors, panels, or fabricated cabinets.

The inputs for this scenario

  • Scrapped charger enclosures: 18 enclosures (held at the documented default)
  • Cost per enclosure or enclosure set: 420 $ / enclosure (held at the documented default)
  • Scrap cost assigned to this issue: 72 % (the input this scenario stresses; the baseline uses 100)
  • Disposition, replacement, or freight adders: 900 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable enclosure scrap cost = scrapped enclosures × cost per enclosure × assigned share.
  • Total enclosure scrap cost works out to 6,343 $ at these inputs, and this is the headline figure for the scenario.
  • Enclosure scrap cost per scrapped enclosure works out to 352 $ / enclosure at these inputs.
  • Variable enclosure scrap cost works out to 5,443 $ at these inputs.
  • Disposition, replacement, or freight adders works out to 900 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where scrap cost assigned to this issue sits at 100% and the headline result is 8,460 $, this scenario comes in 25.02% below the baseline at 6,343 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to scrap cost assigned to this issue, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It captures direct part and logistics cost only; it omits the lost machine time, downstream line stoppage, and any tooling rework that the scrap mode may also be driving.

Results at a glance

  • Total enclosure scrap cost: 6,343 $ (headline result)
  • Enclosure scrap cost per scrapped enclosure: 352 $ / enclosure
  • Variable enclosure scrap cost: 5,443 $
  • Disposition, replacement, or freight adders: 900 $
