Control Board Rework Cost Calculator at 72% rework cost captured in estimate: a worked example
This worked example runs the control board rework cost calculator numbers for a tougher week than the baseline: 72% rework cost captured in estimate instead of the typical 100%. Estimate rework cost for appliance control boards from reworked boards, labor and parts cost per board, rework capture rate, and fixed debug cost.
The inputs for this scenario
- Control boards requiring rework: 420 boards (held at the documented default)
- Labor and parts cost per reworked board: 18.5 $ / board (held at the documented default)
- Rework cost captured in estimate: 72 % (the input this scenario stresses; the baseline uses 100)
- Fixed debug or engineering support cost: 900 $ (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Variable rework cost = control boards requiring rework × labor and parts cost per reworked board × rework cost captured in estimate.
- Total control board rework cost works out to 6,494 $ at these inputs, and this is the headline figure for the scenario.
- Cost per reworked board works out to 15.46 $ / board at these inputs.
- Variable rework cost works out to 5,594 $ at these inputs.
- Fixed debug or engineering support cost works out to 900 $ at these inputs.
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 25.09% below the baseline at 6,494 $.
- Use it when sizing the cost of a defect excursion, comparing rework versus scrap, or budgeting engineering support for a recurring failure mode. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
Results at a glance
- Total control board rework cost: 6,494 $ (headline result)
