Warranty Claim Rate Calculator at 1.73% target warranty claim rate: a worked example

Push target warranty claim rate up to 1.73% and the picture changes. This example computes every intermediate figure at that operating point. a reliability or service quality team needs to monitor appliance warranty claim performance

The inputs for this scenario

  • Warranty claims received: 1,380 claims (unchanged)
  • Appliance or HVAC units shipped: 82,000 units (unchanged)
  • Target warranty claim rate: 1.73 % (raised for this scenario; the documented default is 1.5)

Working through the calculation

  • Applying the documented formula (Warranty claim rate = warranty claims received ÷ appliance or HVAC units shipped × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 1.68 % for warranty claim rate, the number this scenario is built around.
  • At this operating point the engine returns 0.05 points for claim-rate gap to target.
  • At this operating point the engine returns 1,380 claims for warranty claims received.
  • At this operating point the engine returns 82,000 units for units shipped.

How this compares with the baseline

  • Against the tool's baseline example, where target warranty claim rate sits at 1.5% and the headline result is 1.68 %, this scenario lands almost exactly on the baseline at 1.68 %.
  • It computes the warranty claim rate as claims divided by units shipped times 100, and the point gap between that rate and your target. 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.
