Formulation Yield at 68% target formulation yield: a worked example

This worked example runs the formulation yield numbers for a tougher week than the baseline: 68% target formulation yield instead of the typical 95%. Calculate formulation yield from acceptable bulk or filled amount versus theoretical batch amount.

The inputs for this scenario

  • Acceptable formulated amount: 8 count (held at the documented default)
  • Theoretical formulation amount: 250 count (held at the documented default)
  • Target formulation yield: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Formulation yield = Acceptable formulated amount ÷ Theoretical formulation amount × 100.
  • Formulation 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.
  • Acceptable formulated amount works out to 8 count at these inputs.
  • Theoretical formulation amount works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target formulation yield sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it after compounding to score a formulation batch against theory, when troubleshooting hold-up or filter losses, or when reconciling bulk before fill. 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

  • Formulation yield: 3.2 % (headline result)
