Rejection Rate Cost at 2.3% target rejection rate: a worked example

What does the result look like when target rejection rate reaches 2.3%? The full calculation is worked below with real intermediate numbers. Use it during a daily QC tier-board review when complaints from a retail DC come in, or when a cultivar or new clamshell film is on trial and you need to compare rejection vs control.

The inputs for this scenario

  • Rejected packs (QC + DC + customer): 65 packs (unchanged)
  • Total packs inspected or shipped: 5,000 packs (unchanged)
  • Target rejection rate: 2.3 % (raised for this scenario; the documented default is 2)

Working through the calculation

  • Applying the documented formula (Actual rejection rate = rejected packs ÷ total packs inspected or shipped × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 1.3 % for actual rejection rate, the number this scenario is built around.
  • At this operating point the engine returns 1 points for gap to rejection target.
  • At this operating point the engine returns 65 count for rejected packs (qc + dc + customer).
  • At this operating point the engine returns 5,000 count for total packs inspected or shipped.

How this compares with the baseline

  • Against the tool's baseline example, where target rejection rate sits at 2% and the headline result is 1.3 %, this scenario lands almost exactly on the baseline at 1.3 %.
  • A figure at this level is achievable when target rejection rate is genuinely sustained, not just peaked for a shift. It treats every rejected pack as equal weight; it does not value differences in cost between a QC pull and a customer return, which is usually far more expensive.

Results at a glance

  • Actual rejection rate: 1.3 % (headline result)
  • Gap to rejection target: 1 points
  • Rejected packs (QC + DC + customer): 65 count
  • Total packs inspected or shipped: 5,000 count
