Repair Reserve at 4.32% expected warranty claim rate: a worked example

Suppose expected warranty claim rate falls to 4.32%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate the warranty and repair reserve to set aside for a batch of luxury jewelry or watches sold. Based on historical repair rates, average repair cost, and the expected claim percentage over the warranty period. Helps finance teams, retail buyers, and brand managers budget for post-sale service obligations on high-value goods.

The inputs for this scenario

  • Pieces sold during warranty period: 200 pieces (held at the documented default)
  • Average repair cost per warranty claim: 175 $ / claim (held at the documented default)
  • Expected warranty claim rate: 4.32 % (the input this scenario stresses; the baseline uses 6)
  • Fixed service program cost: 500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable repair reserve = pieces sold × average repair cost × claim rate / 100.
  • Total repair reserve works out to 2,012 $ at these inputs, and this is the headline figure for the scenario.
  • Repair reserve per piece sold works out to 10.06 $ / piece at these inputs.
  • Variable repair reserve works out to 1,512 $ at these inputs.
  • Fixed service program cost works out to 500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected warranty claim rate sits at 6% and the headline result is 2,600 $, this scenario comes in 22.62% below the baseline at 2,012 $.
  • It computes the total dollars to reserve for warranty repairs plus fixed service program cost, and the reserve allocated per piece sold. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
