Pharmaceutical Packaging & Serialization worked example

Recall Trace Depth with serialized units in the recall trace scope of 50 units: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop serialized units in the recall trace scope to 50 units, then walk the calculation through step by step. Estimate recall trace depth for pharmaceutical packaging and serialization using production-ready inputs so teams can quote the work, compare cost scenarios, or review margin risk.

The inputs for this scenario

  • Serialized units in the recall trace scope: 50 units (the input this scenario stresses; the baseline uses 100)
  • Per-unit investigation and trace cost: 2.5 $ / unit (held at the documented default)
  • Fixed recall event setup cost: 75 $ (held at the documented default)
  • QA labor and overhead adder: 25 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total recall trace depth cost = recall trace depth quantity × variable recall trace depth cost + fixed recall trace depth cost + labor and overhead adder.
  • Total recall trace depth cost works out to 225 $ at these inputs, and this is the headline figure for the scenario.
  • Cost per unit works out to 4.5 $ / piece at these inputs.
  • Variable recall trace depth cost works out to 125 $ at these inputs.
  • Fixed recall trace depth adders works out to 100 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where serialized units in the recall trace scope sits at 100 units and the headline result is 350 $, this scenario comes in 35.71% below the baseline at 225 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to serialized units in the recall trace scope, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a single flat per-unit trace rate; real recalls often have tiered costs where deeper aggregation levels (case, pallet, shipper) cost far more per saleable unit to unwind.

Results at a glance

  • Total recall trace depth cost: 225 $ (headline result)
  • Cost per unit: 4.5 $ / piece
  • Variable recall trace depth cost: 125 $
  • Fixed recall trace depth adders: 100 $
