Raw Material Substitution Impact with batch volume affected of 2,500 gal: a worked example

This worked example runs the raw material substitution impact numbers for a tougher week than the baseline: batch volume affected of 2,500 gal instead of the typical 5,000 gal. Estimate the net cost impact of switching a raw material from batch volume, cost change per gallon, requalification cost, and reformulation labor.

The inputs for this scenario

  • Batch volume affected: 2,500 gal (the input this scenario stresses; the baseline uses 5,000)
  • Cost change per gallon: 0.15 $ / gal (held at the documented default)
  • Requalification and testing cost: 1,200 $ (held at the documented default)
  • Reformulation labor adder: 600 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Material cost change = batch volume affected * cost change per gallon.
  • Total substitution cost impact works out to 2,175 $ at these inputs, and this is the headline figure for the scenario.
  • Cost impact per gallon works out to 0.87 $ / piece at these inputs.
  • Material cost change works out to 375 $ at these inputs.
  • Requalification and labor cost works out to 1,800 $ at these inputs.

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 14.71% below the baseline at 2,175 $.
  • Use it when evaluating a supplier switch, a cheaper alternative raw, or a mandated reformulation, before committing to the change. 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 substitution cost impact: 2,175 $ (headline result)
  • Cost impact per gallon: 0.87 $ / piece
  • Material cost change: 375 $
  • Requalification and labor cost: 1,800 $
