Rework Cost at 43% share requiring full teardown rework: a worked example in uav & drone manufacturing

Suppose share requiring full teardown rework falls to 43%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate the labor and bench cost of reworking drones that fail flight test, calibration, or functional checks before shipment.

The inputs for this scenario

  • Drones flagged at flight test: 85 units (held at the documented default)
  • Teardown and rebuild labor per unit: 140 $ / unit (held at the documented default)
  • Share requiring full teardown rework: 43 % (the input this scenario stresses; the baseline uses 60)
  • Failure-analysis and retest setup cost: 1,200 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Rework cost = drones flagged x teardown and rebuild labor per unit x share needing full rework + failure analysis and retest setup.
  • Total rework cost works out to 6,317 $ at these inputs, and this is the headline figure for the scenario.
  • Rework cost per unit works out to 74.32 $ / piece at these inputs.
  • Variable rework cost works out to 5,117 $ at these inputs.
  • Fixed rework cost adder works out to 1,200 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share requiring full teardown rework sits at 60% and the headline result is 8,340 $, this scenario comes in 24.26% below the baseline at 6,317 $.
  • It multiplies flagged drones by per-unit rebuild labor and the share needing full rework, then adds a fixed failure-analysis and retest setup cost. 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: 6,317 $ (headline result)
  • Rework cost per unit: 74.32 $ / piece
  • Variable rework cost: 5,117 $
  • Fixed rework cost adder: 1,200 $
