Takt time calculator

How takt time is calculated

Takt time is the net available production time divided by customer demand for the same period. It is not how fast you can work; it is how often one finished unit has to leave the line so that output matches what customers order. The calculator subtracts planned breaks from the shift, converts the result to seconds and divides by the units required.

Example: an 8-hour shift is 480 minutes. Remove a 30-minute lunch and 450 minutes, or 27,000 seconds, remain. If customers need 450 units per shift, takt time is 27,000 ÷ 450 = 60 seconds per unit, which is 60 units an hour. A bottleneck station with a 54-second cycle time can build 500 units in that time, so it has 10% headroom.

Using takt time on the shop floor

Compare takt with the cycle time of every station. Any step slower than takt is a bottleneck that guarantees missed output or overtime; a step much faster than takt usually means idle operators or a pile of work in progress waiting downstream. Lean practitioners often plan to run slightly faster than takt, a figure sometimes called planned cycle time, to absorb small stoppages and changeovers.

Takt changes whenever demand changes, so recalculate it when the order book moves rather than treating it as a fixed property of the line. The most frequent mistake is using gross shift time: if you forget to remove breaks, team meetings or planned maintenance, the takt looks generous and the line falls behind every day. The opposite error is subtracting unplanned downtime; that belongs in your efficiency or OEE figures, not in takt.

The word comes from the German Takt, the beat of a conductor's baton, and the idea was refined by Toyota as part of its production system. It works best for repetitive work with steady demand. In job shops where every order differs, average takt across a product family is only a rough guide.
