Both bars show the time between one finished unit and the next. The dashed line marks the takt time the customer demand requires.
Takt time is the rate at which finished units must be completed to meet customer demand in the time available. It sets the heartbeat for planning a production line: if demand needs one unit every 64 seconds, a process that delivers one every 68 seconds will fall behind.
Takt Time = Net Available Production Time ÷ Customer Demand, where Net Available Production Time = Shift Duration − Planned Non-Production Time.
The pace the customer demand requires: the interval at which one finished unit has to come out. It depends only on the time available and the demand, not on how your process performs.
The interval you actually observe between one finished unit and the next. It describes the process, and it is not the same as processing time at one station, batch duration or production lead time.
In this calculator: the theoretical output over the whole available time if the process kept delivering one unit every observed cycle time, with no other losses.
Limits of this calculator: it covers one product or one consistently defined output unit, using one demand figure. Batch operations, parallel machines, product mixes and changeovers need additional analysis. The comparison assumes continuous output at the observed cycle time with no stoppages, defects or other losses, so it is not a forecast. Meeting takt on paper does not guarantee that orders are delivered on time.
An illustrative shift: 480 minutes with 30 minutes of planned non-production time, a demand of 420 units, and an observed cycle time of 68 seconds. These are the values the calculator opens with.
| Measure | Value | How |
|---|---|---|
| Shift Duration | 480 min | |
| Planned Non-Production Time | 30 min | Breaks, cleaning and meetings |
| Net Available Production Time | 450 min | 480 − 30 = 27,000 s |
| Customer Demand | 420 units | |
| Required Takt Time | 64.3 s per unit | 27,000 ÷ 420 |
| Required Production Rate | 56.0 units/hour | 420 ÷ 7.5 h |
| Observed Cycle Time | 68 s per unit | |
| Actual Production Rate | 52.9 units/hour | 3,600 ÷ 68 |
| Theoretical Output | 397.1 units (397 complete) | 27,000 ÷ 68 |
| Potential Shortfall | 23 units (5.5% of demand) | 397 − 420 |
| Pace comparison | Behind | 68 s is slower than 64.3 s (pace ratio 94.5%) |
| Additional Time Required | 26.0 min | 420 × 68 ÷ 60 − 450 (idealised) |
At 68 seconds per unit the process is 3.7 seconds per unit slower than the 64.3 seconds the demand requires. Over the shift that adds up to a potential shortfall of 23 whole units, if nothing else went wrong.
Takt time = Net Available Production Time ÷ Customer Demand. Net Available Production Time is the Shift Duration minus Planned Non-Production Time. With 450 minutes (27,000 seconds) available and a demand of 420 units, takt time is 27,000 ÷ 420 = 64.3 seconds per unit.
Everything planned in which the process is not meant to produce: breaks, cleaning, team meetings, planned maintenance and similar periods. Unplanned stops such as breakdowns are not included here. They are a loss against the pace, not time you removed in advance.
No. Takt time is the pace the customer demand needs. Cycle time is the interval your process actually delivers finished units. Comparing the two tells you whether the process is, on paper, faster or slower than the demand requires.
Not necessarily. The comparison assumes the process delivers a unit every observed cycle time, all the time, with no stoppages, defects or other losses. Real processes lose time, so many teams plan to run faster than takt to leave room for losses. The result is a pace comparison, not a production forecast.
Customers need whole units, so the potential surplus or shortfall counts only complete units. The theoretical output is kept as a decimal as supporting information, for example 397.1 units, of which 397 are complete.
It is the extra production time that would be needed to make the full demand at the observed cycle time, if there were no other losses: Demand × Cycle Time ÷ 60 − Net Available Production Time, and never below zero. It is an idealised figure, not a prediction or guaranteed overtime.
This version works with one product, or one consistently defined output unit, and one demand figure. If the mix or the demand changes, calculate each case separately. Product mixes, changeovers, batch operations and parallel machines need additional analysis that this calculator does not do.
Takt time says how fast you need to go. OEE shows how much of your planned time was truly productive, once stops, slow running and defects are taken out. A process that looks fast enough against takt can still fall short if it has low OEE. You can measure that with the free OEE calculator.
