Chemical Mix Cost at 110% formula or order scope included: a worked example

This scenario runs the chemical mix cost calculation on the strong side: 110% formula or order scope included, with every other input held at its documented default. Use it when isocyanate, polyol, resin, blowing agent, catalyst, filler, fire retardant, colorant, adhesive, or recycled-content cost changes affect finished foam cost.

The inputs for this scenario

  • Chemical mix weight: 1,250 lb (unchanged)
  • Blended chemical cost: 2.35 $ / lb (unchanged)
  • Formula or order scope included: 110 % (raised for this scenario; the documented default is 100)
  • Fixed mix setup, purge, or QC cost: 450 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable chemical mix cost = chemical mix weight × blended chemical cost × formula or order scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 3,681 $ for total chemical mix cost, the number this scenario is built around.
  • At this operating point the engine returns 2.95 $ / piece for chemical cost per finished scope.
  • At this operating point the engine returns 3,231 $ for variable chemical mix cost.
  • At this operating point the engine returns 450 $ for fixed mix setup, purge, or qc cost.

How this compares with the baseline

  • Against the tool's baseline example, where formula or order scope included sits at 100% and the headline result is 3,388 $, this scenario comes in 8.67% above the baseline at 3,681 $.
  • Use it when quoting a foam pour, comparing batch sizes, or deciding whether a small order carries enough volume to absorb fixed changeover and purge cost. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total chemical mix cost: 3,681 $ (headline result)
  • Chemical cost per finished scope: 2.95 $ / piece
  • Variable chemical mix cost: 3,231 $
  • Fixed mix setup, purge, or QC cost: 450 $
