Data Center & Infrastructure Equipment Manufacturing worked example

Infrastructure Warranty Reserve at 92% warranty exposure share: a worked example

Push warranty exposure share up to 92% and the picture changes. This example computes every intermediate figure at that operating point. Use it when infrastructure warranty reserve in data center and infrastructure equipment manufacturing is being put through a data center and infrastructure equipment manufacturing weighted-cost review.

The inputs for this scenario

  • Shipped infrastructure units covered: 100 units (unchanged)
  • Expected warranty cost per unit: 45 $ / unit (unchanged)
  • Warranty exposure share: 92 % (raised for this scenario; the documented default is 80)
  • Fixed campaign or support cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Expected warranty claim cost = shipped units covered × expected warranty cost per unit × warranty exposure share) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total warranty reserve, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for warranty reserve per shipped unit.
  • At this operating point the engine returns 4,140 $ for expected warranty claim cost.
  • At this operating point the engine returns 250 $ for fixed campaign or support cost.

How this compares with the baseline

  • Against the tool's baseline example, where warranty exposure share sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • It computes total warranty reserve as shipped units times expected cost per unit times exposure share, plus a fixed campaign or support cost. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Total warranty reserve: 4,390 $ (headline result)
