Pharmaceutical, Biotech & GMP Manufacturing worked example

Validation Batch Cost at 58% validation cost scope: a worked example in pharmaceutical, biotech & gmp manufacturing

This worked example runs the validation batch cost numbers for a tougher week than the baseline: 58% validation cost scope instead of the typical 80%. Estimate process validation batch cost from validation lot count, cost per lot, included scope, and fixed protocol or report cost.

The inputs for this scenario

  • Validation batches or PPQ lots: 100 lots (held at the documented default)
  • Cost per validation batch: 45 $ / lot (held at the documented default)
  • Validation cost scope: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed protocol and report cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable GMP validation batch cost = Validation batches or PPQ lots × Cost per validation batch × Validation cost scope.
  • Total validation batch cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Validation cost per lot works out to 28.6 $ / piece at these inputs.
  • Variable validation lot cost works out to 2,610 $ at these inputs.
  • Fixed validation documentation cost works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where validation cost scope sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • Use it when scoping a process validation or PPQ campaign for a new product, site transfer, or major change that triggers revalidation. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total validation batch cost: 2,860 $ (headline result)
  • Validation cost per lot: 28.6 $ / piece
  • Variable validation lot cost: 2,610 $
  • Fixed validation documentation cost: 250 $
