GMP Batch Cost at 92% costed batch scope: a worked example

What does the result look like when costed batch scope reaches 92%? The full calculation is worked below with real intermediate numbers. Use it when GMP, QA, QC, validation, manufacturing, or operations teams need a quick planning estimate to compare batch economics, quote CDMO work, or explain cost per released lot before finance review.

The inputs for this scenario

  • Number of GMP batches or lots: 100 lots (unchanged)
  • Direct cost per batch or lot: 45 $ / lot (unchanged)
  • Costed batch scope: 92 % (raised for this scenario; the documented default is 80)
  • Fixed GMP support cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable GMP batch cost = Number of GMP batches or lots × Direct cost per batch or lot × Costed batch scope) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total gmp batch cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for gmp batch cost per lot.
  • At this operating point the engine returns 4,140 $ for variable batch cost.
  • At this operating point the engine returns 250 $ for fixed gmp support cost.

How this compares with the baseline

  • Against the tool's baseline example, where costed batch scope 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 costed batch scope is genuinely sustained, not just peaked for a shift. The scope percentage is a blunt instrument — if only part of your campaign is fully costed, this pro-rates linearly and will understate cost when the uncosted lots are more complex than average.
