Line Labor Balance at 61% line balance efficiency: a worked example

This worked example runs the line labor balance numbers for a tougher week than the baseline: 61% line balance efficiency instead of the typical 85%. Estimate the labor cost of a balanced production line after accounting for bottleneck idle time and changeover rebalancing.

The inputs for this scenario

  • Total Station Labor Hours: 96 hrs (held at the documented default)
  • Loaded Labor Rate: 34 $/hr (held at the documented default)
  • Line Balance Efficiency: 61 % (the input this scenario stresses; the baseline uses 85)
  • Changeover Labor Cost: 450 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Balanced labor cost = station hours x loaded rate x balance efficiency% + changeover labor.
  • Total line labor balance cost works out to 2,441 $ at these inputs, and this is the headline figure for the scenario.
  • Line labor balance cost per unit works out to 25.43 $ / piece at these inputs.
  • Variable line labor balance cost works out to 1,991 $ at these inputs.
  • Fixed line labor balance adder works out to 450 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where line balance efficiency sits at 85% and the headline result is 3,224 $, this scenario comes in 24.29% below the baseline at 2,441 $.
  • Use it when evaluating a line rebalance, comparing station layouts, or budgeting labor for a product with frequent changeovers. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total line labor balance cost: 2,441 $ (headline result)
  • Line labor balance cost per unit: 25.43 $ / piece
  • Variable line labor balance cost: 1,991 $
  • Fixed line labor balance adder: 450 $
