Electronics Warranty Reserve at 92% expected warranty claim rate: a worked example

What does the result look like when expected warranty claim rate reaches 92%? The full calculation is worked below with real intermediate numbers. Use it when electronics warranty reserve in electronics repair, refurbishment and depot operations is being put through a electronics repair, refurbishment and depot operations weighted-cost review.

The inputs for this scenario

  • Covered electronics units in field: 100 units (unchanged)
  • Expected cost per warranty claim: 45 $ / claim (unchanged)
  • Expected warranty claim rate: 92 % (raised for this scenario; the documented default is 80)
  • Fixed warranty support reserve: 250 $ (unchanged)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where expected warranty claim rate sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • A figure at this level is achievable when expected warranty claim rate is genuinely sustained, not just peaked for a shift. It uses a single average cost per claim and a flat claim rate, so it won't capture failure curves that spike early (infant mortality) or late (wear-out), or cost variation between cheap and expensive repairs.
