Pharma Batch Yield at 68% target batch yield: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target batch yield to 68%, then walk the calculation through step by step. Calculate pharmaceutical batch yield from released good units versus total started or filled units, with a target yield comparison.

The inputs for this scenario

  • Released good units: 8 count (held at the documented default)
  • Total started or filled units: 250 count (held at the documented default)
  • Target batch yield: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Pharma batch yield = Released good units ÷ Total started or filled units × 100.
  • Pharma batch yield works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Yield gap to target works out to 64.8 points at these inputs.
  • Released good units works out to 8 count at these inputs.
  • Total batch units works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target batch yield sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target batch yield, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It is a unit-count yield only — it does not assess potency, content uniformity, or whether the gap stems from a legitimate yield loss versus an accountability error that GMP requires you to explain.
