Retraining Cost at 58% share of retraining done on paid production time: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop share of retraining done on paid production time to 58%, then walk the calculation through step by step. Estimate the cost of retraining a workforce after a process change, revised standard, or corrective action.

The inputs for this scenario

  • Workers requiring retraining: 35 workers (held at the documented default)
  • Retraining cost per worker: 420 $/worker (held at the documented default)
  • Share of retraining done on paid production time: 58 % (the input this scenario stresses; the baseline uses 80)
  • Updated curriculum and materials cost: 5,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Retraining cost = workers x cost per worker x on-clock share + updated curriculum and materials.
  • Total retraining cost works out to 13,526 $ at these inputs, and this is the headline figure for the scenario.
  • Retraining cost per unit works out to 386 $ / piece at these inputs.
  • Variable retraining cost works out to 8,526 $ at these inputs.
  • Fixed retraining cost adder works out to 5,000 $ at these inputs.

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 19.3% below the baseline at 13,526 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to share of retraining done on paid production time, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. 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: 13,526 $ (headline result)
  • Retraining cost per unit: 386 $ / piece
  • Variable retraining cost: 8,526 $
  • Fixed retraining cost adder: 5,000 $
