Hospital Equipment & Clinical Furniture worked example
Warranty Reserve at 4.6% historical warranty claim rate: a worked example in hospital equipment & clinical furniture
Push historical warranty claim rate up to 4.6% and the picture changes. This example computes every intermediate figure at that operating point. Use it when setting the warranty reserve for a hospital equipment product line, reviewing claim reserve adequacy at quarter end, or building warranty cost into a multi-year service contract quote.
The inputs for this scenario
- Units shipped in the period: 200 units (unchanged)
- Average warranty cost per claim: 215 $ / claim (unchanged)
- Historical warranty claim rate: 4.6 % (raised for this scenario; the documented default is 4)
- Fixed warranty administration cost: 800 $ (unchanged)
Working through the calculation
- Applying the documented formula (Variable warranty reserve = units shipped × average cost per claim × (claim rate / 100)) to the inputs above produces each figure below.
- At this operating point the engine returns 2,778 $ for total warranty reserve, the number this scenario is built around.
- At this operating point the engine returns 13.89 $ / piece for warranty reserve per unit shipped.
- At this operating point the engine returns 1,978 $ for variable warranty reserve.
- At this operating point the engine returns 800 $ for fixed warranty administration cost.
How this compares with the baseline
- Against the tool's baseline example, where historical warranty claim rate sits at 4% and the headline result is 2,520 $, this scenario comes in 10.24% above the baseline at 2,778 $.
- It computes the total warranty reserve for a shipping period, splitting the volume-driven variable reserve from the fixed program administration 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.
