Photonics Warranty Exposure at 3.45% expected warranty failure rate: a worked example

This scenario runs the photonics warranty exposure calculation on the strong side: 3.45% expected warranty failure rate, with every other input held at its documented default. Use this when setting warranty reserves for a product line, evaluating whether a reliability improvement justifies its cost, or comparing warranty exposure between product generations.

The inputs for this scenario

  • Units under active warranty: 2,000 units (unchanged)
  • Average repair or replacement cost: 450 $ / failure (unchanged)
  • Expected warranty failure rate: 3.45 % (raised for this scenario; the documented default is 3)
  • Fixed warranty program overhead: 8,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable warranty cost = units in warranty x repair cost x failure rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 39,050 $ for total photonics warranty exposure, the number this scenario is built around.
  • At this operating point the engine returns 19.52 $ / piece for warranty cost per unit shipped.
  • At this operating point the engine returns 31,050 $ for variable warranty cost (expected claims).
  • At this operating point the engine returns 8,000 $ for fixed warranty program overhead.

How this compares with the baseline

  • Against the tool's baseline example, where expected warranty failure rate sits at 3% and the headline result is 35,000 $, this scenario comes in 11.57% above the baseline at 39,050 $.
  • Use it when setting a warranty reserve, pricing an extended-warranty offer, or building the business case for a reliability fix on a fielded laser or optical product. 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 photonics warranty exposure: 39,050 $ (headline result)
  • Warranty cost per unit shipped: 19.52 $ / piece
  • Variable warranty cost (expected claims): 31,050 $
  • Fixed warranty program overhead: 8,000 $
