Joint Warranty Exposure at 86% warranty exposure capture factor: a worked example

What does the result look like when warranty exposure capture factor reaches 86%? The full calculation is worked below with real intermediate numbers. Use it when evaluating field risk from loose bolts, leaks, clamp-load loss, stripped inserts, missing fasteners, or torque-control escapes.

The inputs for this scenario

  • Expected joint-related warranty claims: 18 claims (unchanged)
  • Cost per joint warranty claim: 420 $ / claim (unchanged)
  • Warranty exposure capture factor: 86 % (raised for this scenario; the documented default is 75)
  • Fixed investigation or containment cost: 2,500 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable joint warranty exposure = expected claims × cost per claim × exposure factor) to the inputs above produces each figure below.
  • At this operating point the engine returns 9,002 $ for total joint warranty exposure, the number this scenario is built around.
  • At this operating point the engine returns 500 $ / claim for average exposure per claim.
  • At this operating point the engine returns 6,502 $ for variable warranty exposure.
  • At this operating point the engine returns 2,500 $ for fixed response cost.

How this compares with the baseline

  • Against the tool's baseline example, where warranty exposure capture factor sits at 75% and the headline result is 8,170 $, this scenario comes in 10.18% above the baseline at 9,002 $.
  • A figure at this level is achievable when warranty exposure capture factor is genuinely sustained, not just peaked for a shift. It assumes a single average cost per claim, but a catastrophic joint failure can cost far more than a routine retorque, skewing real exposure.

Results at a glance

  • Total joint warranty exposure: 9,002 $ (headline result)
  • Average exposure per claim: 500 $ / claim
  • Variable warranty exposure: 6,502 $
  • Fixed response cost: 2,500 $
