Line Output Per Day Calculator

Work out line output per day instantly with clear inputs, formula shown and shareable results.

About Line Output Per Day Calculator

Line output is available operator minutes times efficiency divided by garment SAM. The gap between that and the 100%-efficiency figure is the improvement headroom, and it is usually large — most sewing lines run at 50-70% efficiency, so output can rise substantially without adding operators.

Formula

Line output

Output = operators x working minutes x efficiency / SAM

Worked example

With the default values below, Line Output Per Day Calculator returns Line Output Per Day of 515. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

What drives efficiency on a sewing line?

Line balance, operator skill on the specific operation, style change frequency, machine breakdowns, and quality rework. New styles typically start at 30-40% and climb over one to two weeks.

Does adding operators raise output proportionally?

Only if the line can be re-balanced to use them. Adding operators to an unbalanced line raises WIP and idle time without raising output.
