Recall Exposure Radius at 25% confirmed defect prevalence: a worked example

This worked example runs the recall exposure radius numbers for a tougher week than the baseline: 25% confirmed defect prevalence instead of the typical 35%. Estimates the financial exposure of a recall based on the suspect unit window and confirmed defect prevalence.

The inputs for this scenario

  • Units in suspect window: 8,000 units (held at the documented default)
  • Recall handling cost per unit: 22 $/unit (held at the documented default)
  • Confirmed defect prevalence: 25 % (the input this scenario stresses; the baseline uses 35)
  • Notification and admin adder: 15,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Recall exposure = suspect units x handling cost per unit x defect prevalence% + admin adder.
  • Total recall exposure radius cost works out to 59,000 $ at these inputs, and this is the headline figure for the scenario.
  • Recall exposure radius cost per unit works out to 7.38 $ / piece at these inputs.
  • Variable recall exposure radius cost works out to 44,000 $ at these inputs.
  • Fixed recall exposure radius adder works out to 15,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where confirmed defect prevalence sits at 35% and the headline result is 76,600 $, this scenario comes in 22.98% below the baseline at 59,000 $.
  • Use it to size a potential recall, compare a narrow versus wide suspect window, or justify traceability spend. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total recall exposure radius cost: 59,000 $ (headline result)
  • Recall exposure radius cost per unit: 7.38 $ / piece
  • Variable recall exposure radius cost: 44,000 $
  • Fixed recall exposure radius adder: 15,000 $
