How to Use This Calculator
  1. Enter target production rate (units/hour) and packaging line efficiency (%).
  2. Enter fill weight per unit (g), number of shifts per day, and operating hours per shift.
  3. Read required line speed (units/minute) and annual packaging throughput (units/year).
  4. Review bottleneck analysis — identify the slowest station limiting overall line speed.
  5. Use throughput data to size downstream case packing and palletizing equipment.

What each input means

Rated Speed (units/min)
Maximum line speed in units per minute.
Shift Duration (hours)
Total shift length.
OEE (%)
Overall Equipment Effectiveness. World-class: 85%+.
Changeover Time (min)
Minutes per product changeover.
Changeovers per Shift
Number of product changeovers per shift.

What each result means

Units per Shift
Total output per shift after OEE and changeover losses.
Units per Hour
Effective hourly output.
Effective Speed (UPM)
OEE-adjusted units per minute.
Available Run Time (min)
Production time after changeovers.
Availability (%)
Run time as percentage of total shift.
Line Cost/Unit ($)
Packaging cost per unit at $200/hr line rate.
Bottleneck? (1=Yes)
Flag if OEE is below 50%.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Rated Speed (units/min) = 60, Shift Duration (hours) = 8, OEE (%) = 75, Changeover Time (min) = 30 = 5 input(s) provided
  2. Calculate Units per Shift
    Units per Shift = effectiveSpeed * availableMin
    18900 = 18900
  3. Calculate Units per Hour
    Units per Hour = effectiveSpeed * 60
    2700 = 2700
  4. Calculate Effective Speed
    Effective Speed = ratedSpeedUPM * (oeePercent / 100)
    45 = 45
