Short answer
Takt time is available production time ÷ customer demand for the same period. With 870 net minutes of run time per day and demand of 620 units, takt is 84.2 seconds per unit. Your actual cycle time must be at or below takt, or you will miss demand every day.
Takt time is the drumbeat: the interval at which one finished unit has to leave the line for the customer to be satisfied. It is arithmetic on demand, not a measurement of your plant, which is exactly why it is useful — it tells you the pace you have to hit before you look at whether you can.
This takt time calculator takes your shift pattern, planned stops and customer demand, returns takt in seconds and minutes, then compares it against your actual cycle time to show the daily shortfall or headroom and the number of stations your work content needs.

Net time per shift = (8 × 60) − 45 = 435 min
Available time = 435 × 2 shifts = 870 min = 52,200 s
Takt = 52,200 s ÷ 620 units = 84.2 s per unit
Stations = 410 s work content ÷ 84.2 s takt = 4.87 → 5
At 92.0s your cycle time is 7.8s above the 84.2s takt, so the line finishes 567 units against demand of 620 — short by 53 a day. Closing it takes 81 extra minutes of run time, or 7.8s off the constraint cycle.

The formula
Takt time = Net available production time ÷ Customer demand (same period)
Net available production time
Scheduled time minus breaks, meetings and planned stops. Shift length × shifts, less non-working minutes per shift.
Customer demand
Units the customer needs in that same period. Demand, not what the line feels capable of.
Actual cycle time
Time between two finished units leaving the process today, measured at the constraint.
Work content
Total hands-on time to build one unit across all operations, excluding walking and waiting.
Takt is set by the customer; cycle time is set by your process. Two rules follow: never plan a cycle time above takt, and never remove planned breaks from the denominator to make takt look achievable. Required stations = work content ÷ takt, rounded up.

Result
Takt = 84.2 s per unit · actual cycle 92 s · 5 stations required
Net available time is (480 − 45) × 2 = 870 minutes, or 52,200 seconds. Divide by 620 units and takt is 84.2 seconds — one unit must leave the line every 84 seconds. At the actual 92-second cycle the line makes 567 units a day, so it is 53 units short and needs 81 extra minutes to close the gap. Work content of 410 seconds ÷ 84.2 gives 4.87, so you need 5 stations, loaded to 97.4% of takt — tight enough that a single missed cycle costs you output.
How this takt time calculator handles shifts and breaks
Available time means time the line can actually build product. Breaks, shift handover, planned meetings, scheduled maintenance and cleandown all come out first. Padding the numerator is the most common way teams end up with a takt they can never hit and a plan nobody believes.
Include in available time?
Item
Why
No
Breaks and lunch
The line is stopped. Leaving them in makes takt shorter than reality allows.
No
Planned maintenance and cleandown
Scheduled non-production time, same treatment as breaks.
No
Shift handover and daily meetings
Real minutes, and they repeat every shift.
Yes
Changeover time
It happens inside production time. Count it here and it will show up as an availability loss in OEE.
Yes
Unplanned downtime
Takt is a target on scheduled time. Downtime is a reason you miss it, not a reason to lower the bar.
What comes out of available time before you divide by demand.
Takt, cycle time and lead time are three different numbers
Takt time — how often a unit must be finished. Set by demand. Changes when the forecast changes.
Cycle time — how often a unit is finished. Set by the process, measured at the constraint.
Work content — total hands-on seconds per unit across all operations. Divided by takt, it gives the station count.
Lead time — how long one unit takes to travel the whole route, queues included. Usually hours or days when takt is seconds. Break that down with the manufacturing lead time calculator.
When cycle time is above takt
You have four honest levers, in rough order of cost: add available time (overtime or an extra shift), reduce the cycle at the constraint, rebalance work between stations so no station exceeds takt, or add a station. Overtime is the fastest and the most expensive per unit; rebalancing is usually the cheapest and gets skipped because it requires measuring every station rather than the line.

Line balance, and keeping takt current
Line balance efficiency = work content ÷ (stations × takt). The example runs at 97.4%, which sounds excellent and is actually fragile: nearly every second of every station is committed, so one jam costs output directly. Below about 85% you are paying for idle time somewhere — look for the operation nobody has re-timed since the product changed. Whether the asset can hold the pace at all is an OEE question, and whether you already own enough capacity is a capacity utilization question.
Takt is only as good as the demand figure inside it, and demand moves. Recalculate when the forecast shifts more than about 10%, at every changeover to a product with different work content, and whenever the shift pattern changes — a takt board showing last quarter's demand is worse than no takt board. That means pulling demand by item from open orders and forecast, plus net available minutes from the shift calendar. With ERPray you ask for both directly and read the query it generated, so the number on the board traces back to the orders behind it.
Frequently asked questions
How do you calculate takt time?
Divide net available production time by customer demand for the same period. Net available time is shift length × shifts, minus breaks and planned stops. Two 8-hour shifts with 45 minutes of breaks each give 870 minutes, or 52,200 seconds; against demand of 620 units that is a takt time of 84.2 seconds per unit.
What is the difference between takt time and cycle time?
Takt time is how often a unit must be completed to meet demand — it comes from the customer. Cycle time is how often your process actually completes one, measured at the constraint. Cycle time must be at or below takt. If cycle time is 92 seconds against an 84-second takt, you will fall short every shift.
Should breaks be included in available time?
No. Breaks, lunch, handover and planned maintenance come out of available time before you divide by demand, because the line is not building during them. Changeovers and unplanned downtime stay inside, since they happen during production time and should surface as availability losses rather than shrink your takt target.
How many stations do I need for a given takt time?
Divide total work content per unit by takt time and round up. With 410 seconds of work content and an 84.2-second takt, 410 ÷ 84.2 = 4.87, so you need 5 stations. Then check line balance efficiency — work content ÷ (stations × takt) — because 5 stations only work if no single station exceeds takt.
What happens if cycle time is much faster than takt time?
You have headroom, which is comfortable but not free. Either demand is understated, the line is overstaffed for the current volume, or you are building ahead into inventory. Overproduction ties up cash and hides problems, so slow the line to takt and move the freed labour, rather than letting it run and stockpile.
Can takt time be used in low-volume or job shop production?
Yes, but per family rather than per part. Group products with similar work content, use average demand and average work content for the family, and recalculate whenever mix shifts. In genuinely one-off production takt loses meaning and lead time becomes the better control number.
