Daily Production Target Calculator (Shift Target)
Determine total expected daily shift target quantity for sewing floor planning and target board display.
Set the target before the shift starts, write it on the line target board, and compare actual output against it every hour. A realistic target keeps the line balanced: set it too high and operators rush and quality drops, set it too low and paid minutes go unused.
What is Daily Production Target?
The daily production target is the number of garment pieces a sewing line is planned to complete in one shift. Industrial engineering sets it from four facts: how many operators are on the line, how long the shift runs, the standard minute value (SMV) of the garment, and the efficiency the line is expected to achieve. It is the number supervisors chase during the shift, the number written on the target board, and the number used for shipment planning and incentive calculations.
Target is not the same as capacity. Capacity is the theoretical maximum at 100% efficiency, which no real line sustains all day. Target applies a realistic efficiency, typically 70 to 80% for an established line, so the plan is challenging but achievable. If you need the maximum figure instead, use the Line Capacity Calculator, which runs the same formula at 100% efficiency.
Formula
Daily Target = [(Operators × Shift Hours × 60) / SMV] × (Target Efficiency % / 100)
- Operators: number of sewing operators actually working on the line.
- Shift Hours: planned working hours in the shift, excluding unpaid breaks.
- 60: converts hours into minutes, because SMV is measured in minutes.
- SMV: standard minutes needed to make one complete garment.
- Target Efficiency %: expected line efficiency, for example 75 for 75%.
Hourly Target = Daily Target / Shift Hours. This calculator rounds both results down to whole pieces, so a calculated 112.5 pieces per hour is shown as 112.
How to Calculate
- Take the garment SMV from the IE department or the latest time study, and confirm it matches the current style and operation breakdown.
- Count the operators who will actually be on the line for the full shift, not the sanctioned headcount.
- Multiply operators by shift hours and by 60 to get total available man-minutes.
- Divide total available man-minutes by the SMV to get the maximum possible output.
- Multiply by the target efficiency as a decimal to get the daily target, then divide by shift hours for the hourly target.
Example
A line has 30 operators working an 8-hour shift on a polo shirt with an SMV of 12.0 minutes, at a target efficiency of 75%. Total available minutes = 30 × 8 × 60 = 14,400 minutes. Maximum output = 14,400 / 12.0 = 1,200 pieces. Daily target = 1,200 × 0.75 = 900 pieces per day. Hourly target = 900 / 8 = 112.5, shown as 112 pieces per hour. If the same line later reaches 85% efficiency, the target rises to 1,200 × 0.85 = 1,020 pieces per day, which is why efficiency improvement is worth more than overtime.
The same 900-piece day can be checked from the demand side: 900 pieces in 8 hours means one piece must leave the line every 32 seconds, which is exactly what the Takt Time Calculator gives for this demand. And before promising the 900, check that no single operation is a bottleneck with the Machine Capacity Calculator.
Assumptions
This calculation assumes the SMV is accurate and current, all counted operators are present for the full shift, and the efficiency figure already covers normal allowances such as bundle handling, minor machine stops, and rework. It does not add overtime hours, absentee cover, or style-changeover time: if any of those apply, adjust the operator count or the shift hours before calculating, rather than inflating the efficiency figure to compensate.
