Payment Terminal & Retail Hardware worked example

Warranty Reserve at 4.6% projected warranty claim rate: a worked example in payment terminal & retail hardware

Push projected warranty claim rate up to 4.6% and the picture changes. This example computes every intermediate figure at that operating point. Use it to set the per-unit accrual that funds future repair and replacement obligations on a hardware sale.

The inputs for this scenario

  • Terminals sold under warranty: 25,000 units (unchanged)
  • Expected repair or replace cost per claim: 58 $/unit (unchanged)
  • Projected warranty claim rate: 4.6 % (raised for this scenario; the documented default is 4)
  • Fixed reserve administration cost: 6,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Warranty reserve = units sold x repair cost per unit x projected claim rate% + administration cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 72,700 $ for total warranty reserve cost, the number this scenario is built around.
  • At this operating point the engine returns 2.91 $ / piece for warranty reserve cost per unit.
  • At this operating point the engine returns 66,700 $ for variable warranty reserve cost.
  • At this operating point the engine returns 6,000 $ for fixed warranty reserve adder.

How this compares with the baseline

  • Against the tool's baseline example, where projected warranty claim rate sits at 4% and the headline result is 64,000 $, this scenario comes in 13.59% above the baseline at 72,700 $.
  • It computes total warranty reserve as units sold times repair cost per claim times projected claim rate, plus fixed administration cost, and the reserve per terminal sold. 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.
