Ammunition Component Rework Cost Calculator at 72% share of rework actually charged to this lot: a worked example

Suppose share of rework actually charged to this lot falls to 72%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate rework cost from reworked component count or hours, rework cost rate, recoverable share, and fixed disposition cost.

The inputs for this scenario

  • Components reworked or rework labor hours: 1,800 units or hr (held at the documented default)
  • Cost to rework one unit or one hour: 0.42 $ / unit or hr (held at the documented default)
  • Share of rework actually charged to this lot: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed disposition, MRB, or setup cost: 650 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable rework cost = reworked component count or hours × rework cost rate × applied rework cost share.
  • Total rework cost impact works out to 1,194 $ rework cost at these inputs, and this is the headline figure for the scenario.
  • Rework cost rate works out to 0.66 $ / piece at these inputs.
  • Variable rework cost works out to 544 $ at these inputs.
  • Fixed disposition or setup cost works out to 650 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of rework actually charged to this lot sits at 100% and the headline result is 1,406 $ rework cost, this scenario comes in 15.06% below the baseline at 1,194 $ rework cost.
  • It computes total rework cost impact by combining variable rework (quantity times rate times capture share) with a fixed disposition or setup cost, and derives an effective per-piece rate. 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.

Results at a glance

  • Total rework cost impact: 1,194 $ rework cost (headline result)
  • Rework cost rate: 0.66 $ / piece
  • Variable rework cost: 544 $
  • Fixed disposition or setup cost: 650 $
