Garment SAM Labor Cost at 75% line efficiency: a worked example

This scenario runs the garment sam labor cost calculation on the strong side: 75% line efficiency, with every other input held at its documented default. Use it to convert a garment SAM into a costed labor figure for line balancing and quoting decisions.

The inputs for this scenario

  • Standard minutes per garment: 18 SAM (unchanged)
  • Sewing labor cost per minute: 0.14 $/minute (unchanged)
  • Line efficiency: 75 % (raised for this scenario; the documented default is 65)
  • Line setup and bundle handling: 0.3 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Note: efficiency below 100% raises real cost; effective cost = SAM x rate / (efficiency/100)) to the inputs above produces each figure below.
  • At this operating point the engine returns 2.19 $ for total garment sam labor cost, the number this scenario is built around.
  • At this operating point the engine returns 0.12 $ / piece for garment sam labor cost per unit.
  • At this operating point the engine returns 1.89 $ for variable garment sam labor cost.
  • At this operating point the engine returns 0.3 $ for fixed garment sam labor cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where line efficiency sits at 65% and the headline result is 1.94 $, this scenario comes in 13% above the baseline at 2.19 $.
  • Use it when costing a new style, comparing sewing lines, or validating a CMT quote against your standard minute value. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
