Production calculator
Line Balance Calculator
Compare station work content against takt to find bottlenecks, unused time, and balance efficiency before changing staffing or work split.
What this calculator does
- Measure station balance, bottleneck time, balance efficiency, and idle time across a line.
- Use when assigning work across stations or checking whether a line can meet takt.
- Measures station balance efficiency, bottleneck station time, idle time, and takt gap across a four-station line sample.
Formula used
- Bottleneck time = longest station time
- Balance efficiency = total work content ÷ (stations × bottleneck time)
- Idle time per cycle = stations × bottleneck time − total work content
- Takt gap = target takt − bottleneck time
Inputs explained
- Station 1 time: undefined
- Station 2 time: undefined
- Station 3 time: undefined
- Station 4 time: undefined
- Target takt: undefined
How to use the result
- Use it when redistributing work, adding operators, or checking whether station times can meet takt.
- The calculator uses entered station averages; detailed balance work should also review precedence, walking, ergonomic limits, and variation.
Common questions
- What is the Line Balance calculator for? It compares station cycle times with each other and with takt so teams can see bottlenecks and idle time across the line.
- What information do I need before using it? Enter measured cycle time for each station and the target takt time in seconds per unit.
- How should I use line balance efficiency? Use it to decide which work elements to move, whether to add support at the bottleneck, or whether the takt target is unrealistic.
- When is the result only an estimate? It is only an estimate when station times are based on a few observations, mixed models have different work content, or operators share tasks across stations.
