Ceramic Batch Yield at 66% target first-quality yield: a worked example

Suppose target first-quality yield falls to 66%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate first-quality yield for a ceramic tile or sanitaryware batch against a production yield target.

The inputs for this scenario

  • First-quality ceramic pieces: 22,800 pieces (held at the documented default)
  • Total ceramic pieces produced or inspected: 25,000 pieces (held at the documented default)
  • Target first-quality yield: 66 % (the input this scenario stresses; the baseline uses 92)

Working through the calculation

  • The calculation starts from the formula this tool documents: First-quality batch yield = first-quality ceramic pieces ÷ total ceramic pieces produced or inspected × 100.
  • First-quality batch yield works out to 91.2 % at these inputs, and this is the headline figure for the scenario.
  • Yield gap to target works out to -25.2 points at these inputs.
  • First-quality ceramic pieces works out to 22,800 count at these inputs.
  • Total ceramic pieces produced or inspected works out to 25,000 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target first-quality yield sits at 92% and the headline result is 91.2 %, this scenario lands almost exactly on the baseline at 91.2 %.
  • It divides first-quality pieces by total pieces produced or inspected to give a yield percentage, then reports the gap in points to your target. 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.

Results at a glance

  • First-quality batch yield: 91.2 % (headline result)
  • Yield gap to target: -25.2 points
  • First-quality ceramic pieces: 22,800 count
  • Total ceramic pieces produced or inspected: 25,000 count
