Door Hardware Labor at 92% billable-time capture factor: a worked example

Push billable-time capture factor up to 92% and the picture changes. This example computes every intermediate figure at that operating point. Use it when door hardware labor in trailers, truck bodies and specialty vehicles is being put through a trailers, truck bodies and specialty vehicles weighted-cost review.

The inputs for this scenario

  • Doors or hinge/latch sets installed: 100 units (unchanged)
  • Labor rate per hardware set: 45 $ / unit (unchanged)
  • Billable-time capture factor: 92 % (raised for this scenario; the documented default is 80)
  • Fixed setup and consumables cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Door Hardware Labor cost = quantity × rate × capture factor + fixed cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for weighted cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for per piece value.
  • At this operating point the engine returns 4,140 $ for captured value.
  • At this operating point the engine returns 250 $ for fixed adjustment.

How this compares with the baseline

  • Against the tool's baseline example, where billable-time 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 door hardware installation labor cost and the per-door labor cost from a unit count, labor rate, billable capture factor, and a fixed cost. 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.

Results at a glance

  • Weighted cost: 4,390 $ (headline result)
  • Per piece value: 43.9 $ / piece
  • Captured value: 4,140 $
  • Fixed adjustment: 250 $
