Work out labour standard minutes instantly with clear inputs, formula shown and shareable results.
Standard minute value is the sum of operation basic times uplifted by allowance. Dividing SMV by expected line efficiency gives the actual operator minutes a garment will really consume, which is the figure to use for costing and capacity planning rather than the theoretical SMV.
Standard minute value
SMV = operations x average operation time x (1 + allowance %)
Real consumption
Actual minutes per piece = SMV / line efficiency
Standard allowed minutes and standard minute value mean the same thing in garment manufacturing — basic time plus allowances for one complete garment.
By comparing earned minutes against actual output over a settled run. If operators consistently beat SMV by a wide margin the standard is loose, and if nobody reaches it the method or the rating was wrong.
