Cleaning Labor at 92% labor capture factor: a worked example

Push labor capture factor up to 92% and the picture changes. This example computes every intermediate figure at that operating point. Use it when degreasing, flux residue removal, ultrasonic cleaning, tube flushing, header cleaning, or post-braze cleanup needs to be included in cost or capacity reviews.

The inputs for this scenario

  • Cleaning labor hours: 100 hr (unchanged)
  • Loaded cleaning labor rate: 45 $ / hr (unchanged)
  • Labor capture factor: 92 % (raised for this scenario; the documented default is 80)
  • Fixed cleaning supply cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Captured cleaning labor cost = cleaning labor hours × loaded labor rate × labor capture factor + fixed cleaning supply cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for captured cleaning labor cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / hr for cleaning cost per labor hour.
  • At this operating point the engine returns 4,140 $ for captured labor cost.
  • At this operating point the engine returns 250 $ for fixed cleaning supply cost.

How this compares with the baseline

  • Against the tool's baseline example, where labor capture factor sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • It computes total captured cleaning cost as labor hours times loaded rate times capture factor, plus fixed supply cost, then divides by hours for a cost-per-hour figure. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
