Desalination & Membrane Water Treatment Equipment worked example

Project Margin with contracted plant sell price of 310 $: a worked example in desalination & membrane water treatment equipment

Push contracted plant sell price up to 310 $ and the picture changes. This example computes every intermediate figure at that operating point. Use it when project margin in desalination and membrane water treatment equipment needs a clean margin number for a desalination and membrane water treatment equipment go / no-go review.

The inputs for this scenario

  • Contracted plant sell price: 310 $ (raised for this scenario; the documented default is 125)
  • Fully-loaded project delivery cost: 100 $ (unchanged)
  • Recognized project revenue (margin base): 100 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Project gross margin dollars = project sell price - required project cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 210 % for project margin, the number this scenario is built around.
  • At this operating point the engine returns 210 value for project gross margin dollars.
  • At this operating point the engine returns 310 value for project sell price.
  • At this operating point the engine returns 100 value for required project cost.

How this compares with the baseline

  • Against the tool's baseline example, where contracted plant sell price sits at 125 $ and the headline result is 25 %, this scenario comes in 740% above the baseline at 210 %.
  • It subtracts fully-loaded delivery cost from the contracted sell price, then divides that gross profit by the recognized revenue base to give a margin percentage. 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.
