Foam, Insulation & Cushioning Products worked example

Trim Scrap Cost at 72% scrap allocation to this job: a worked example in foam, insulation & cushioning products

This worked example runs the trim scrap cost numbers for a tougher week than the baseline: 72% scrap allocation to this job instead of the typical 100%. Estimate cost of foam, insulation board, laminated pad, or cushioning material lost to trim, saw kerf, edge defects, and setup scrap.

The inputs for this scenario

  • Trim scrap volume or area: 145 ft³ (held at the documented default)
  • Foam material cost per scrap unit: 3.2 $ / ft³ (held at the documented default)
  • Scrap allocation to this job: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed disposal or reclaim handling cost: 175 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable trim scrap cost = trim scrap volume or area × foam material cost per scrap unit × scrap allocation to this job.
  • Total trim scrap cost works out to 509 $ at these inputs, and this is the headline figure for the scenario.
  • Scrap cost per allocated unit works out to 3.51 $ / piece at these inputs.
  • Variable trim scrap cost works out to 334 $ at these inputs.
  • Fixed disposal or reclaim handling cost works out to 175 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where scrap allocation to this job sits at 100% and the headline result is 639 $, this scenario comes in 20.33% below the baseline at 509 $.
  • Use it when quoting a fabricated part, comparing nesting layouts, or building a business case for a rebond or grinding line. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total trim scrap cost: 509 $ (headline result)
