Line Balancing Calculator

How this is calculated

Line balancing efficiency compares the real work content to the total time the line reserves for it. Every station is allotted one takt of time, so the line reserves stations × takt seconds per unit; the useful part is the actual work content.

Balance delay is the idle time built into the line: capacity you pay for but cannot use because work is unevenly split. If takt or station count is zero the calculator shows a dash.

What this deliberately leaves out

• Station times should sit just under takt. This uses takt as the station allowance. If your slowest station runs longer than takt, that bottleneck sets the real pace, not this average.
• Task indivisibility. Real tasks cannot always be split to hit the theoretical minimum; precedence and equipment constraints limit how work moves.
• No variation. Manual station times vary unit to unit. A line balanced on averages still stalls on bad cycles.
• Set takt from demand. Use the takt time calculator so the station allowance reflects real customer demand.

Balancing is one piece of flow. See the wider lean manufacturing approach, check station pace against real output with the cycle time & throughput calculator, and read how a manufacturing operating system keeps balance visible over time.
