Acoustic Product Rework Cost at 35% expected affected share: a worked example

What does the result look like when expected affected share reaches 35%? The full calculation is worked below with real intermediate numbers. a quality manager or estimator needs the cost exposure of rejected acoustic parts or failed NVH tests

The inputs for this scenario

  • Potentially affected components: 120 components (unchanged)
  • Rework cost per component: 38 $ / component (unchanged)
  • Expected affected share: 35 % (raised for this scenario; the documented default is 30)
  • Inspection/retest cost: 650 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Expected rework subtotal = affected components × rework cost per component × expected affected share) to the inputs above produces each figure below.
  • At this operating point the engine returns 2,246 $ for total rework cost, the number this scenario is built around.
  • At this operating point the engine returns 18.72 $ / component for expected cost per component.
  • At this operating point the engine returns 1,596 $ for expected rework subtotal.
  • At this operating point the engine returns 650 $ for inspection/retest cost.

How this compares with the baseline

  • Against the tool's baseline example, where expected affected share sits at 30% and the headline result is 2,018 $, this scenario comes in 11.3% above the baseline at 2,246 $.
  • A figure at this level is achievable when expected affected share is genuinely sustained, not just peaked for a shift. It assumes a single flat rework cost per part; mixed failure modes (some scrapped, some reglued, some only retested) need separate runs or a blended rate.

Results at a glance

  • Total rework cost: 2,246 $ (headline result)
  • Expected cost per component: 18.72 $ / component
  • Expected rework subtotal: 1,596 $
  • Inspection/retest cost: 650 $
