Bioplastic Material Cost at 110% material cost allocation share: a worked example

Push material cost allocation share up to 110% and the picture changes. This example computes every intermediate figure at that operating point. a processor needs to cost a biomaterial lot, resin substitution, molded part, compostable film run, or packaging program

The inputs for this scenario

  • Bioplastic resin or compound weight: 2,500 kg or lb (unchanged)
  • Landed material cost: 3.85 $ / kg or lb (unchanged)
  • Material cost allocation share: 110 % (raised for this scenario; the documented default is 100)
  • Fixed material setup and freight cost: 850 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Allocated variable material cost = bioplastic resin or compound weight × landed material cost × material cost allocation share) to the inputs above produces each figure below.
  • At this operating point the engine returns 11,438 $ for total bioplastic material cost, the number this scenario is built around.
  • At this operating point the engine returns 4.58 $ / kg or lb for landed material cost.
  • At this operating point the engine returns 10,588 $ for allocated variable material cost.
  • At this operating point the engine returns 850 $ for fixed material setup and freight cost.

How this compares with the baseline

  • Against the tool's baseline example, where material cost allocation share sits at 100% and the headline result is 10,475 $, this scenario comes in 9.19% above the baseline at 11,438 $.
  • It computes total bioplastic material cost by multiplying resin weight by landed cost and an allocation share, then adding fixed setup and freight. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Total bioplastic material cost: 11,438 $ (headline result)
  • Landed material cost: 4.58 $ / kg or lb
  • Allocated variable material cost: 10,588 $
  • Fixed material setup and freight cost: 850 $
