Gypsum, Drywall & Interior Panel Manufacturing worked example

Margin with board selling price per msf of 63 $ / MSF: a worked example in gypsum, drywall & interior panel manufacturing

This worked example runs the margin numbers for a tougher week than the baseline: board selling price per msf of 63 $ / MSF instead of the typical 125 $ / MSF. Calculate gross margin per MSF for a gypsum board order by comparing selling price to total production cost per MSF.

The inputs for this scenario

  • Board selling price per MSF: 63 $ / MSF (the input this scenario stresses; the baseline uses 125)
  • Total production cost per MSF: 100 $ / MSF (held at the documented default)
  • Reference selling price: 100 $ / MSF (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross margin per MSF = selling price per MSF - total production cost per MSF.
  • Margin works out to -37 % at these inputs, and this is the headline figure for the scenario.
  • Absolute margin works out to -37 value at these inputs.
  • Available amount works out to 63 value at these inputs.
  • Required amount works out to 100 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where board selling price per msf sits at 125 $ / MSF and the headline result is 25 %, this scenario comes in 248% below the baseline at -37 %.
  • Use it when pricing a board order, evaluating a customer's profitability, or checking whether a price increase keeps margin above target. 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

  • Margin: -37 % (headline result)
