Tool Sharpening, Reconditioning & Industrial Repair Services worked example

Warranty/Rework Cost at 92% share of cost the shop absorbs: a worked example

This scenario runs the warranty/rework cost calculation on the strong side: 92% share of cost the shop absorbs, with every other input held at its documented default. Use it when warranty/rework cost in tool sharpening, reconditioning and industrial repair services is being put through a tool sharpening, reconditioning and industrial repair services weighted-cost review.

The inputs for this scenario

  • Tools requiring warranty regrind or rework: 100 units (unchanged)
  • Rework cost per tool: 45 $ / unit (unchanged)
  • Share of cost the shop absorbs: 92 % (raised for this scenario; the documented default is 80)
  • Fixed handling and freight cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Warranty/Rework Cost cost = quantity × rate × capture factor + fixed cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for weighted cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for per piece value.
  • At this operating point the engine returns 4,140 $ for captured value.
  • At this operating point the engine returns 250 $ for fixed adjustment.

How this compares with the baseline

  • Against the tool's baseline example, where share of cost the shop absorbs sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • Use it when a batch comes back for warranty, when negotiating a credit split with a customer, or when reserving for expected rework on a new contract. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Weighted cost: 4,390 $ (headline result)
