Scrap Fin/Tube Cost at 58% recoverable cost capture factor: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop recoverable cost capture factor to 58%, then walk the calculation through step by step. Estimate the financial impact of scrapped fins and tubes from scrap quantity, material cost, capture factor, and fixed handling or disposal cost.

The inputs for this scenario

  • Scrapped fins or tubes: 100 units (held at the documented default)
  • Material cost per scrapped fin or tube: 45 $ / unit (held at the documented default)
  • Recoverable cost capture factor: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed scrap handling and disposal cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Fin and tube scrap cost = scrapped units × material cost per unit × cost capture factor + fixed scrap handling cost.
  • Fin and tube 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.
  • Captured material loss works out to 2,610 $ at these inputs.
  • Fixed handling cost works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where recoverable cost capture factor sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to recoverable cost capture factor, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It captures material and fixed handling cost only; it excludes the labor, machine time and overhead already added to a partially built coil, so the true loss on a scrapped finished assembly is higher.

Results at a glance

  • Fin and tube scrap cost: 2,860 $ (headline result)
  • Scrap cost per affected unit: 28.6 $ / piece
  • Captured material loss: 2,610 $
  • Fixed handling cost: 250 $
