Gypsum, Drywall & Interior Panel Manufacturing worked example

Margin with board selling price per msf of 310 $ / MSF: a worked example in gypsum, drywall & interior panel manufacturing

Push board selling price per msf up to 310 $ / MSF and the picture changes. This example computes every intermediate figure at that operating point. Use it during a quote review to confirm the margin per MSF clears the minimum threshold before accepting a board order.

The inputs for this scenario

  • Board selling price per MSF: 310 $ / MSF (raised for this scenario; the documented default is 125)
  • Total production cost per MSF: 100 $ / MSF (unchanged)
  • Reference selling price: 100 $ / MSF (unchanged)

Working through the calculation

  • Applying the documented formula (Gross margin per MSF = selling price per MSF - total production cost per MSF) to the inputs above produces each figure below.
  • At this operating point the engine returns 210 % for margin, the number this scenario is built around.
  • At this operating point the engine returns 210 value for absolute margin.
  • At this operating point the engine returns 310 value for available amount.
  • At this operating point the engine returns 100 value for required amount.

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 740% above the baseline at 210 %.
  • It computes gross margin per MSF as selling price minus total production cost, then divides by a reference selling price to express margin as a percent. 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.
