Bioplastic Margin with quoted bioplastic selling price of 9,300 $: a worked example

This worked example runs the bioplastic margin numbers for a tougher week than the baseline: quoted bioplastic selling price of 9,300 $ instead of the typical 18,500 $. Calculate margin for bioplastic resin, compound, molded parts, films, sheets, or compostable packages from selling amount, required cost, and margin reference basis.

The inputs for this scenario

  • Quoted bioplastic selling price: 9,300 $ (the input this scenario stresses; the baseline uses 18,500)
  • Required biomaterial cost: 14,200 $ (held at the documented default)
  • Reference selling amount: 18,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Bioplastic margin dollars = quoted bioplastic selling amount - required biomaterial cost.
  • Bioplastic quote margin works out to -26.49 % margin at these inputs, and this is the headline figure for the scenario.
  • Bioplastic margin dollars works out to -4,900 $ at these inputs.
  • Quoted bioplastic selling amount works out to 9,300 $ at these inputs.
  • Required biomaterial cost works out to 14,200 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where quoted bioplastic selling price sits at 18,500 $ and the headline result is 23.24 % margin, this scenario comes in 214% below the baseline at -26.49 % margin.
  • Use it at quote time to confirm a bioplastic job clears your minimum margin, and to re-check margin when feedstock prices move after the quote was issued. 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.
