Overtime Cost Calculator at 92% overtime premium capture factor: a worked example

This scenario runs the overtime cost calculator calculation on the strong side: 92% overtime premium capture factor, with every other input held at its documented default. Use it when overtime cost in safety and workforce is being put through a safety and workforce weighted-cost review.

The inputs for this scenario

  • Overtime hours worked: 100 units (unchanged)
  • Overtime pay rate per hour: 45 $ / unit (unchanged)
  • Overtime premium capture factor: 92 % (raised for this scenario; the documented default is 80)
  • Fixed overtime adder (callout or shift premium): 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Weighted cost = quantity × rate × capture factor + fixed adjustment) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total overtime cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for overtime cost per unit.
  • At this operating point the engine returns 4,140 $ for variable overtime cost.
  • At this operating point the engine returns 250 $ for fixed overtime cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where overtime premium capture factor sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • Use it before authorizing overtime to compare it against alternatives, or after the fact to reconcile what a stretch of overtime actually cost. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
