Demand Forecast Gap with forecasted or committed barrier-film demand of 310 value: a worked example in specialty films, membranes & barrier materials

What does the result look like when forecasted or committed barrier-film demand reaches 310 value? The full calculation is worked below with real intermediate numbers. Use it when demand forecast gap in specialty films, membranes and barrier materials needs a clean margin number for a specialty films, membranes and barrier materials go / no-go review.

The inputs for this scenario

  • Forecasted or committed barrier-film demand: 310 value (raised for this scenario; the documented default is 125)
  • Actual firm orders or consumption: 100 value (unchanged)
  • Baseline demand used for the comparison: 100 value (unchanged)

Working through the calculation

  • Applying the documented formula (Demand forecast gap amount gap = available demand forecast gap amount - required demand forecast gap amount) to the inputs above produces each figure below.
  • At this operating point the engine returns 210 % for demand forecast gap margin, the number this scenario is built around.
  • At this operating point the engine returns 210 value for demand forecast gap amount gap.
  • At this operating point the engine returns 310 value for available demand forecast gap amount.
  • At this operating point the engine returns 100 value for required demand forecast gap amount.

How this compares with the baseline

  • Against the tool's baseline example, where forecasted or committed barrier-film demand sits at 125 value and the headline result is 25 %, this scenario comes in 740% above the baseline at 210 %.
  • A figure at this level is achievable when forecasted or committed barrier-film demand is genuinely sustained, not just peaked for a shift. A single-period gap can be noise; it reflects only the three amounts you enter and does not distinguish a systematic bias from normal demand variability without a trend behind it.
