Yield with input units started of 1,000 units: a worked example

Suppose input units started falls to 1,000 units. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate production yield from input quantity, good output, scrap, and rework.

The inputs for this scenario

  • Input units started: 1,000 units (the input this scenario stresses; the baseline uses 2,000)
  • Good units out: 1,908 units (held at the documented default)
  • Scrapped units: 58 units (held at the documented default)
  • Reworked units: 34 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Yield = good units รท input units.
  • Yield works out to 100 % at these inputs, and this is the headline figure for the scenario.
  • Loss rate works out to 0 % at these inputs.
  • Scrap rate works out to 5.8 % at these inputs.
  • Rework rate works out to 3.4 % at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where input units started sits at 2,000 units and the headline result is 95.4 %, this scenario comes in 4.82% above the baseline at 100 %.
  • It computes overall process yield as good units divided by units started, plus the loss, scrap, and rework rates that make up the gap. 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

  • Yield: 100 % (headline result)
  • Loss rate: 0 %
  • Scrap rate: 5.8 %
  • Rework rate: 3.4 %
