Should changeovers come out of available time for takt?

Yes, if they are on the schedule. Takt uses net available time, which excludes breaks and expected stoppages such as scheduled maintenance and team briefings. Unplanned breakdowns stay in, so the gap between bottleneck cycle and takt has to cover them.

My bottleneck is under takt, so why do we still miss shipments?

Because the takt check assumes the bottleneck runs every available minute. Breakdowns, slow cycles and scrap remakes all eat the slack between bottleneck cycle and takt. If that slack is smaller than the share of time your downtime log shows lost, the line still falls short.

How do I set takt for several products on one line?

Enter total demand for all products over the period. That gives an average takt. A model whose cycle at any station runs over takt needs a leveled mix, so it never arrives back to back.

Do I use forecast demand or firm orders?

Use the quantity you must ship in the period: firm orders plus any forecast you commit to build. Recalculate whenever the schedule changes that quantity, because every station target moves with takt.

Production calculator

Takt Time Calculator

Find the takt time a line must hold to ship customer demand, and whether your slowest station can keep that pace. You need shift length, planned stops, shifts, demand and the bottleneck cycle.

What this calculator does

The pace a line must hold to meet customer demand, checked against the bottleneck cycle.

Formula used

Available time = (shift length − breaks and planned stops) × number of shifts
Takt time = available time × 60 ÷ customer demand; required rate = demand ÷ (available time ÷ 60)
Bottleneck load = bottleneck cycle time ÷ takt time × 100
Output at bottleneck pace = available time × 60 ÷ bottleneck cycle time; surplus over demand = output − demand
Overtime to meet demand = larger of 0 and (demand × bottleneck cycle time ÷ 60 − available time)

Inputs explained

Shift Length: Scheduled minutes per shift, start to finish, before breaks.
Breaks and Planned Stops: Breaks, meetings and scheduled maintenance per shift.
Number of Shifts: Shifts worked in the period the demand covers.
Customer Demand: Good units due in those shifts, from orders or the schedule.
Bottleneck Cycle Time: Slowest station's running cycle, timed on the floor.

How to use the result

Best suited to setting station targets for a new line layout, checking a demand increase against the shift pattern, choosing between overtime and another shift.
Compares the bottleneck with takt at full uptime; real stops and scrap need a cycle faster than takt. Does not balance stations or assign work to them.

Current U.S. benchmarks

The U.S. has 21,668 machinery manufacturing establishments employing about 1,086,146 workers (Census County Business Patterns, 2023).
