Weighing, Dosing & Loss-in-Weight Feeding worked example

Overfeed Cost at 92% recoverable and captured fraction: a worked example

What does the result look like when recoverable and captured fraction reaches 92%? The full calculation is worked below with real intermediate numbers. Use it when overfeed cost in weighing, dosing and loss-in-weight feeding is being put through a weighing, dosing and loss-in-weight feeding weighted-cost review.

The inputs for this scenario

  • Overfed quantity over the run: 100 units (unchanged)
  • Material cost per overfed unit: 45 $ / unit (unchanged)
  • Recoverable / captured fraction: 92 % (raised for this scenario; the documented default is 80)
  • Fixed rework or adjustment cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Overfeed Cost cost = quantity × rate × capture factor + fixed cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for weighted cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for per piece value.
  • At this operating point the engine returns 4,140 $ for captured value.
  • At this operating point the engine returns 250 $ for fixed adjustment.

How this compares with the baseline

  • Against the tool's baseline example, where recoverable and captured fraction sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • A figure at this level is achievable when recoverable and captured fraction is genuinely sustained, not just peaked for a shift. It prices the raw material giveaway and a fixed adjustment charge only; it does not value downstream quality effects, spec violations, or scrapped finished goods caused by overdosing.
