Warranty and Field Claim Reserve Calculator at 72% applied reserve share: a worked example

This worked example runs the warranty and field claim reserve calculator numbers for a tougher week than the baseline: 72% applied reserve share instead of the typical 100%. Estimate reserve cost from shipped quantity or claim count, reserve cost rate, applied reserve share, and fixed investigation cost.

The inputs for this scenario

  • Shipped rounds or expected field-claim count: 250,000 units or claims (held at the documented default)
  • Reserve cost per round or per claim: 0.01 $ / unit or claim (held at the documented default)
  • Applied reserve share (claim probability): 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed investigation and administration cost: 1,200 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable reserve amount = shipped units or expected claim count × reserve cost rate × applied reserve share.
  • Total warranty reserve works out to 2,280 $ reserve at these inputs, and this is the headline figure for the scenario.
  • Reserve cost rate works out to 0.01 $ / piece at these inputs.
  • Variable reserve amount works out to 1,080 $ at these inputs.
  • Fixed investigation or administration cost works out to 1,200 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where applied reserve share sits at 100% and the headline result is 2,700 $ reserve, this scenario comes in 15.56% below the baseline at 2,280 $ reserve.
  • Use it at lot release, at period close, or when pricing a new load so the expected field-claim and return liability is funded before claims actually arrive. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total warranty reserve: 2,280 $ reserve (headline result)
  • Reserve cost rate: 0.01 $ / piece
  • Variable reserve amount: 1,080 $
  • Fixed investigation or administration cost: 1,200 $
