Deviation Cost at 58% deviation scope included: a worked example

Suppose deviation scope included falls to 58%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate cost from GMP deviations using event count, investigation cost per event, applicable scope, and fixed remediation cost.

The inputs for this scenario

  • GMP deviation count: 100 deviations (held at the documented default)
  • Average investigation cost: 45 $ / deviation (held at the documented default)
  • Deviation scope included: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed remediation or CAPA cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable GMP deviation cost = GMP deviation count × Average investigation cost × Deviation scope included.
  • Total GMP deviation cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Deviation cost per event works out to 28.6 $ / piece at these inputs.
  • Allocated investigation cost works out to 2,610 $ at these inputs.
  • Fixed remediation cost works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where deviation scope included sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • It computes the total cost of GMP deviations by combining scope-adjusted investigation cost with a fixed remediation or CAPA charge, then divides to a per-event figure. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
