Overtime Schedule Cost at 99% schedulable overtime share: a worked example

Push schedulable overtime share up to 99% and the picture changes. This example computes every intermediate figure at that operating point. an operations manager needs to evaluate whether overtime is justified for the schedule

The inputs for this scenario

  • Planned overtime hours: 64 hr (unchanged)
  • Overtime labor rate: 78 $ / hr (unchanged)
  • Schedulable overtime share: 99 % (raised for this scenario; the documented default is 92)
  • Supervision and startup cost: 600 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Schedulable overtime labor = planned overtime hours × overtime labor rate × schedulable overtime share) to the inputs above produces each figure below.
  • At this operating point the engine returns 5,542 $ overtime for overtime schedule cost, the number this scenario is built around.
  • At this operating point the engine returns 86.6 $ / hr for overtime labor rate.
  • At this operating point the engine returns 4,942 $ overtime for schedulable overtime labor.
  • At this operating point the engine returns 600 $ for supervision and startup cost.

How this compares with the baseline

  • Against the tool's baseline example, where schedulable overtime share sits at 92% and the headline result is 5,193 $ overtime, this scenario comes in 6.73% above the baseline at 5,542 $ overtime.
  • It computes the total cost of a planned overtime block by multiplying planned hours by the loaded OT rate and the share you can actually schedule, then adding fixed supervision and startup overhead. 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.
