Line Efficiency Calculator

Calculate sewing line efficiency with all required IE fields: day production, SMV, manpower, working hours, and target/day.

Day Production (pcs)

SMV Input Mode

SMV (minutes)

Use this in direct mode when you already know SMV.

Manpower (no. of operators)

Working Hour (hours/day)

Target Efficiency (%)

Line Efficiency Formula

Efficiency % = (Day Production × SMV) / (Manpower × Working Hour × 60) × 100

Target/Day = (Manpower × Working Hour × 60 × Efficiency %) / SMV

SMV = Basic Time + (Basic Time × Allowance)

Example: Production 1,200 pcs, SMV 8 min, Manpower 35, Working Hour 8

Efficiency = (1200×8)/(35×8×60)×100 = 57.14%

If target efficiency is 60%:

Target/Day = (35×8×60×0.60)/8 = 1,260 pcs

What fields are required for accurate line efficiency?

Can SMV be auto-calculated?

What is a good line efficiency?

Calculate daily/hourly production capacity of a sewing line.

Calculate daily production target for a complete sewing line.

Calculate line balancing efficiency and identify bottlenecks.

Calculate Standard Minute Value for garment operations. Essential for production planning and costing.
