Control Board Rework Cost Calculator at 110% rework cost captured in estimate: a worked example

This scenario runs the control board rework cost calculator calculation on the strong side: 110% rework cost captured in estimate, with every other input held at its documented default. a quality or production manager needs to estimate labor and material cost from control board rework

The inputs for this scenario

  • Control boards requiring rework: 420 boards (unchanged)
  • Labor and parts cost per reworked board: 18.5 $ / board (unchanged)
  • Rework cost captured in estimate: 110 % (raised for this scenario; the documented default is 100)
  • Fixed debug or engineering support cost: 900 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable rework cost = control boards requiring rework × labor and parts cost per reworked board × rework cost captured in estimate) to the inputs above produces each figure below.
  • At this operating point the engine returns 9,447 $ for total control board rework cost, the number this scenario is built around.
  • At this operating point the engine returns 22.49 $ / board for cost per reworked board.
  • At this operating point the engine returns 8,547 $ for variable rework cost.
  • At this operating point the engine returns 900 $ for fixed debug or engineering support cost.

How this compares with the baseline

  • Against the tool's baseline example, where rework cost captured in estimate sits at 100% and the headline result is 8,670 $, this scenario comes in 8.96% above the baseline at 9,447 $.
  • Use it when sizing the cost of a defect excursion, comparing rework versus scrap, or budgeting engineering support for a recurring failure mode. 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

  • Total control board rework cost: 9,447 $ (headline result)
  • Cost per reworked board: 22.49 $ / board
  • Variable rework cost: 8,547 $
  • Fixed debug or engineering support cost: 900 $
