How to Use This Calculator
  1. List all workstation tasks with their cycle times in seconds.
  2. Enter the required takt time (customer demand rate) in seconds.
  3. Review the line balance efficiency percentage and idle time per station.
  4. Redistribute tasks to workstations to minimize the number of stations while meeting takt time.
  5. Target a line balance efficiency above 85% — below 75% indicates significant rebalancing opportunity.

What each input means

Total Task Time
Sum of all individual task times in seconds.
Takt Time (Cycle Time)
Target cycle time per station in seconds.
Number of Workstations
Current or planned number of workstations on the line.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Total Task Time = 300, Takt Time (Cycle Time) = 60, Number of Workstations = 6 = 3 input(s) provided
  2. Calculate Line Efficiency
    Line Efficiency = min(lineEfficiency
    83.3 = 83.3%
  3. Calculate Minimum Stations Needed
    Minimum Stations Needed
    5 = 5
  4. Calculate Balance Delay
    Balance Delay = max(balanceDelay
    16.7 = 16.7%
