HVAC Ductwork, Air Handling & Mechanical Products worked example

Labor Utilization at 61% target utilization: a worked example in hvac ductwork, air handling & mechanical products

Suppose target utilization falls to 61%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Measure labor utilization for HVAC Ductwork, Air Handling & Mechanical Products — productive hours as a percentage of paid hours available.

The inputs for this scenario

  • Productive (direct) labor hours: 320 hr (held at the documented default)
  • Paid labor hours available: 400 hr (held at the documented default)
  • Target utilization: 61 % (the input this scenario stresses; the baseline uses 85)

Working through the calculation

  • The calculation starts from the formula this tool documents: Labor utilization = productive labor hours ÷ paid labor hours available.
  • Utilization works out to 80 % at these inputs, and this is the headline figure for the scenario.
  • Gap to target works out to -19 points at these inputs.
  • Used amount works out to 320 value at these inputs.
  • Available amount works out to 400 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target utilization sits at 85% and the headline result is 80 %, this scenario lands almost exactly on the baseline at 80 %.
  • It divides productive direct labor hours by paid labor hours available to give a utilization percentage, then compares that to your target to show the gap in points. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Utilization: 80 % (headline result)
