Labor Standard Calculator at 68% performance efficiency: a worked example

Suppose performance efficiency falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Builds the standard labor cost of a run from allowed hours, a loaded rate, and an efficiency factor.

The inputs for this scenario

  • Standard hours per lot: 120 std hrs (held at the documented default)
  • Fully-loaded labor rate: 38 $/hr (held at the documented default)
  • Performance efficiency: 68 % (the input this scenario stresses; the baseline uses 95)
  • Fixed setup allowance: 600 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Standard labor cost = standard hours x loaded rate x performance efficiency + setup allowance.
  • Total labor standard cost works out to 3,701 $ at these inputs, and this is the headline figure for the scenario.
  • Labor standard cost per unit works out to 30.84 $ / piece at these inputs.
  • Variable labor standard cost works out to 3,101 $ at these inputs.
  • Fixed labor standard adder works out to 600 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where performance efficiency sits at 95% and the headline result is 4,932 $, this scenario comes in 24.96% below the baseline at 3,701 $.
  • It computes total standard labor cost as standard hours times loaded rate times efficiency plus a fixed setup allowance, and derives a cost per hour. 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.
