Sterilization & Sterile Barrier Manufacturing worked example

Validation Batch Cost at 110% program-allocated cost share: a worked example in sterilization & sterile barrier manufacturing

Push program-allocated cost share up to 110% and the picture changes. This example computes every intermediate figure at that operating point. A sterilization validation lead pricing a three-batch PQ and dose-audit program for a new sterile product family.

The inputs for this scenario

  • Number of validation batches: 3 batches (unchanged)
  • Cost per validation batch: 6,500 $/batch (unchanged)
  • Program-allocated cost share: 110 % (raised for this scenario; the documented default is 100)
  • Protocol and audit setup cost: 5,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total validation batch cost = validation batches x cost per batch x program-allocated share + protocol & audit setup) to the inputs above produces each figure below.
  • At this operating point the engine returns 26,450 $ for total validation batch cost, the number this scenario is built around.
  • At this operating point the engine returns 8,817 $ / piece for validation batch cost per unit.
  • At this operating point the engine returns 21,450 $ for variable validation batch cost.
  • At this operating point the engine returns 5,000 $ for fixed validation batch cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where program-allocated cost share sits at 100% and the headline result is 24,500 $, this scenario comes in 7.96% above the baseline at 26,450 $.
  • It multiplies validation batches by cost per batch and an allocation share to get variable cost, adds a fixed protocol and audit setup cost, and returns total cost plus cost per batch. 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.

Results at a glance

  • Total validation batch cost: 26,450 $ (headline result)
  • Validation batch cost per unit: 8,817 $ / piece
  • Variable validation batch cost: 21,450 $
  • Fixed validation batch cost adder: 5,000 $
