Acoustic Trim Yield at 69% target trim yield: a worked example

Suppose target trim yield falls to 69%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate usable trimmed acoustic parts as a percent of parts cut and compare with a trim yield target.

The inputs for this scenario

  • Usable trimmed acoustic parts: 940 parts (held at the documented default)
  • Total parts cut and trimmed: 1,000 parts (held at the documented default)
  • Target trim yield: 69 % (the input this scenario stresses; the baseline uses 96)

Working through the calculation

  • The calculation starts from the formula this tool documents: Trim yield = usable trimmed parts รท total parts cut.
  • Trim yield works out to 94 % at these inputs, and this is the headline figure for the scenario.
  • Gap to target works out to -25 points at these inputs.
  • Usable trimmed parts works out to 940 parts at these inputs.
  • Total parts cut works out to 1,000 parts at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target trim yield sits at 96% and the headline result is 94 %, this scenario lands almost exactly on the baseline at 94 %.
  • It computes trim yield as usable trimmed parts divided by total parts cut, then shows the gap in points to your target yield. 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

  • Trim yield: 94 % (headline result)
  • Gap to target: -25 points
  • Usable trimmed parts: 940 parts
  • Total parts cut: 1,000 parts

Run it with your numbers

  • To rerun this with your own numbers, open the live Acoustic Trim Yield calculator, set target trim yield to your actual value, and adjust the remaining inputs to match your operation.
