Retraining Cost at 92% share of retraining done on paid production time: a worked example

What does the result look like when share of retraining done on paid production time reaches 92%? The full calculation is worked below with real intermediate numbers. Use it when a spec revision or CAPA forces requalification and you need to size the retraining hit before scheduling it against production.

The inputs for this scenario

  • Workers requiring retraining: 35 workers (unchanged)
  • Retraining cost per worker: 420 $/worker (unchanged)
  • Share of retraining done on paid production time: 92 % (raised for this scenario; the documented default is 80)
  • Updated curriculum and materials cost: 5,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Retraining cost = workers x cost per worker x on-clock share + updated curriculum and materials) to the inputs above produces each figure below.
  • At this operating point the engine returns 18,524 $ for total retraining cost, the number this scenario is built around.
  • At this operating point the engine returns 529 $ / piece for retraining cost per unit.
  • At this operating point the engine returns 13,524 $ for variable retraining cost.
  • At this operating point the engine returns 5,000 $ for fixed retraining cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where share of retraining done on paid production time sits at 80% and the headline result is 16,760 $, this scenario comes in 10.53% above the baseline at 18,524 $.
  • A figure at this level is achievable when share of retraining done on paid production time is genuinely sustained, not just peaked for a shift. It captures direct training cost but not the lost-output opportunity cost of pulling workers off the line, which can dwarf the training spend itself on a constrained bottleneck.

Results at a glance

  • Total retraining cost: 18,524 $ (headline result)
  • Retraining cost per unit: 529 $ / piece
  • Variable retraining cost: 13,524 $
  • Fixed retraining cost adder: 5,000 $
