Lot Size Economics at 99% usable lot yield: a worked example

This scenario runs the lot size economics calculation on the strong side: 99% usable lot yield, with every other input held at its documented default. comparing small lots, economic lots, blanket releases, and production batch sizes

The inputs for this scenario

  • Lot-size cost impact per unit: 3.25 $ / unit (unchanged)
  • Quoted lot size: 1,800 units (unchanged)
  • Usable lot yield: 99 % (raised for this scenario; the documented default is 97)
  • Cost impact captured in price: 100 % (unchanged)

Working through the calculation

  • Applying the documented formula (gross lot-size economic impact = lot-size cost impact per unit × quoted lot size) to the inputs above produces each figure below.
  • At this operating point the engine returns 5,792 $ for lot-size economic impact captured, the number this scenario is built around.
  • At this operating point the engine returns 5,850 $ for gross lot-size economic impact.
  • At this operating point the engine returns 58.5 $ for lot-size impact lost to yield.
  • At this operating point the engine returns 0 $ for lot-size impact not captured in price.

How this compares with the baseline

  • Against the tool's baseline example, where usable lot yield sits at 97% and the headline result is 5,675 $, this scenario comes in 2.06% above the baseline at 5,792 $.
  • Use it when comparing lot-size options on a quote, or when deciding whether a volume break or a tooling-driven cost reduction is worth offering the customer. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • lot-size economic impact captured: 5,792 $ (headline result)
  • gross lot-size economic impact: 5,850 $
  • lot-size impact lost to yield: 58.5 $
  • lot-size impact not captured in price: 0 $
