Takt Time Calculator
Takt time from available production time and customer demand — seconds per unit, units per hour, comparison with your cycle time, operators needed and the required output per shift.
How it works
Takt time = available production time ÷ customer demand; operators needed = total work content ÷ takt; line output = available time ÷ bottleneck cycle time
Takt (German for the conductor’s beat) is the pace at which a process must complete a unit to match customer demand exactly — no faster, no slower. It is computed from the time genuinely available for production, after breaks and planned stops, divided by the demand for that period. Every station’s cycle time must then fit inside takt; the slowest station sets the line’s real output, and a station running above takt guarantees a shortfall or overtime. Dividing total work content by takt gives the theoretical operator count, and the gap to the rounded-up number is balance loss. Lean practitioners plan cycle times at 85–95% of takt so ordinary variation does not immediately turn into missed demand, and they recalculate takt whenever demand or shift patterns change.
Worked example
Two 480-minute shifts with 50 minutes of breaks each give 860 minutes a day. Demand of 18,000 units over 20 days is 900 a day, so takt = 51,600 s ÷ 900 = 57.3 s. A 48 s bottleneck cycle runs at 84% of takt (fine); 240 s of work content needs 4.2 → 5 operators.
Frequently asked questions
Takt time vs cycle time vs lead time?
Takt is the demand rate; cycle time is how long a station actually takes per unit; lead time is the total elapsed time for one unit to pass through the whole process including waiting.
Should downtime be subtracted from available time?
Only planned stops (breaks, meetings, cleaning). Unplanned downtime is a loss to fix, not to plan around — otherwise it becomes invisible.
