Raw Material Substitution Impact with batch volume affected of 12,500 gal: a worked example

What does the result look like when batch volume affected reaches 12,500 gal? The full calculation is worked below with real intermediate numbers. you need the full cost picture of swapping a resin, pigment, or additive before approving the substitution

The inputs for this scenario

  • Batch volume affected: 12,500 gal (raised for this scenario; the documented default is 5,000)
  • Cost change per gallon: 0.15 $ / gal (unchanged)
  • Requalification and testing cost: 1,200 $ (unchanged)
  • Reformulation labor adder: 600 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Material cost change = batch volume affected * cost change per gallon) to the inputs above produces each figure below.
  • At this operating point the engine returns 3,675 $ for total substitution cost impact, the number this scenario is built around.
  • At this operating point the engine returns 0.29 $ / piece for cost impact per gallon.
  • At this operating point the engine returns 1,875 $ for material cost change.
  • At this operating point the engine returns 1,800 $ for requalification and labor cost.

How this compares with the baseline

  • Against the tool's baseline example, where batch volume affected sits at 5,000 gal and the headline result is 2,550 $, this scenario comes in 44.12% above the baseline at 3,675 $.
  • A figure at this level is achievable when batch volume affected is genuinely sustained, not just peaked for a shift. It models one substitution event; it does not capture ongoing performance risk, warranty exposure, or yield loss if the new material behaves differently in the field.

Results at a glance

  • Total substitution cost impact: 3,675 $ (headline result)
