Field Complaint Cost at 1.38% expected complaint rate: a worked example in implantable electronics & neurodevices

This scenario runs the field complaint cost calculation on the strong side: 1.38% expected complaint rate, with every other input held at its documented default. Use it when quality, reliability, or finance teams need to quantify complaint handling exposure for neurostimulators, pacemakers, implantable sensors, leads, or accessories.

The inputs for this scenario

  • Shipped devices in complaint scope: 8,000 devices (unchanged)
  • Average cost per complaint: 980 $ / complaint (unchanged)
  • Expected complaint rate: 1.38 % (raised for this scenario; the documented default is 1.2)
  • Fixed complaint investigation adders: 28,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable field complaint cost = shipped devices in complaint scope × average cost per complaint × expected complaint rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 136,192 $ for total field complaint cost, the number this scenario is built around.
  • At this operating point the engine returns 17.02 $ / device for complaint cost per shipped device.
  • At this operating point the engine returns 108,192 $ for variable field complaint cost.
  • At this operating point the engine returns 28,000 $ for fixed complaint investigation adders.

How this compares with the baseline

  • Against the tool's baseline example, where expected complaint rate sits at 1.2% and the headline result is 122,080 $, this scenario comes in 11.56% above the baseline at 136,192 $.
  • Use it when budgeting complaint-handling and post-market surveillance staffing, or when modeling the cost impact of a change in complaint rate. 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

  • Total field complaint cost: 136,192 $ (headline result)
  • Complaint cost per shipped device: 17.02 $ / device
  • Variable field complaint cost: 108,192 $
  • Fixed complaint investigation adders: 28,000 $
