Foam, Insulation & Cushioning Products worked example

Trim Scrap Cost at 110% scrap allocation to this job: a worked example in foam, insulation & cushioning products

This scenario runs the trim scrap cost calculation on the strong side: 110% scrap allocation to this job, with every other input held at its documented default. Use it when trimming buns, splitting sheets, sawing boards, skiving pads, contour cutting, laminating, or converting foam rolls into finished sizes.

The inputs for this scenario

  • Trim scrap volume or area: 145 ft³ (unchanged)
  • Foam material cost per scrap unit: 3.2 $ / ft³ (unchanged)
  • Scrap allocation to this job: 110 % (raised for this scenario; the documented default is 100)
  • Fixed disposal or reclaim handling cost: 175 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable trim scrap cost = trim scrap volume or area × foam material cost per scrap unit × scrap allocation to this job) to the inputs above produces each figure below.
  • At this operating point the engine returns 685 $ for total trim scrap cost, the number this scenario is built around.
  • At this operating point the engine returns 4.73 $ / piece for scrap cost per allocated unit.
  • At this operating point the engine returns 510 $ for variable trim scrap cost.
  • At this operating point the engine returns 175 $ for fixed disposal or reclaim handling cost.

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 7.26% above the baseline at 685 $.
  • Use it when quoting a fabricated part, comparing nesting layouts, or building a business case for a rebond or grinding line. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
