Rework Cost at 72% rework rate: a worked example in outdoor power equipment

Suppose rework rate 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 total rework cost for a build from units needing rework, rework cost per unit, the rework rate, and fixed rework program cost.

The inputs for this scenario

  • Units needing rework: 300 units (held at the documented default)
  • Rework cost per unit: 28 $ / unit (held at the documented default)
  • Rework rate: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed rework program cost: 500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable rework cost = units needing rework × rework cost per unit × rework rate.
  • Total rework cost works out to 6,548 $ at these inputs, and this is the headline figure for the scenario.
  • Rework cost per affected unit works out to 21.83 $ / piece at these inputs.
  • Variable rework cost works out to 6,048 $ at these inputs.
  • Fixed rework program cost works out to 500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where rework rate sits at 100% and the headline result is 8,900 $, this scenario comes in 26.43% below the baseline at 6,548 $.
  • It computes total rework cost by combining a variable per-unit rework spend (scaled by the rework rate) with a fixed program cost, and reports the blended cost per affected unit. 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: 6,548 $ (headline result)
  • Rework cost per affected unit: 21.83 $ / piece
  • Variable rework cost: 6,048 $
  • Fixed rework program cost: 500 $
