Example Data Table
| Scenario | Available time | Demand | Cycle time | Container | Estimated takt | Estimated pitch |
|---|---|---|---|---|---|---|
| Assembly line | 420 minutes | 400 units | 60 seconds | 20 units | 63 seconds | 21 minutes |
| Packing cell | 390 minutes | 650 units | 35 seconds | 25 units | 36 seconds | 15 minutes |
| Machining area | 870 minutes | 300 units | 170 seconds | 10 units | 174 seconds | 29 minutes |
Formula Used
Gross available minutes = shift hours × 60 × number of shifts.
Planned loss minutes = breaks + meetings + changeovers, multiplied by shifts.
Effective available seconds = net available minutes × 60 × downtime factor.
Adjusted demand = required good units ÷ yield factor.
Takt time = effective available seconds ÷ adjusted demand.
Total run time = adjusted demand × current cycle time.
Pitch = takt time × units per container or batch.

Why Takt, Run Time, and Pitch Matter
A lean schedule needs more than a daily target. It needs a clear rhythm. Takt time shows the pace required by customer demand. Run time shows how long the work really takes. Pitch turns that pace into a visible release interval for a container, cart, or batch.
These three values help teams see flow. They also expose pressure before missed shipments appear. When takt is shorter than the actual cycle time, the process cannot keep up without added capacity, reduced waste, or better methods. When run time is far below available time, the team may have room for changeovers, training, or smaller batches.
Using the Numbers
Start with honest available time. Remove breaks, meetings, planned changeovers, and expected downtime. Then compare the remaining time with the demand that must ship. Yield also matters. A process with scrap must make extra units to deliver the required good units.
Pitch is useful on the floor because it is easy to check. For example, if takt is two minutes and each container holds ten units, one container should leave every twenty minutes. Supervisors can compare real movement with the planned pitch during the shift.
Improving Flow
The calculator does not replace observation. It supports better questions. Is demand stable? Are losses recorded correctly? Is the entered cycle time a best case, an average, or a current standard? Each answer changes the plan.
Use the result as a starting point for daily management. Review the takt gap with operators. Check bottlenecks. Balance work between stations. Reduce waiting, walking, searching, and rework. Small gains can move the actual run time closer to the takt target.
Planning with Confidence
Good timing improves communication. Production, planning, quality, and maintenance can discuss the same numbers. A clear takt target gives the line a shared pace. A realistic run time protects capacity. A practical pitch makes the schedule visible. Together, these values turn daily demand into a simple operating plan.
Keep records from each shift. Compare planned values with actual output, downtime, and defects. This habit shows whether the line is improving. It also helps managers adjust staffing, batch size, and maintenance windows before constraints become serious delays during busy production days.
FAQs
What is takt time?
Takt time is the time allowed to make one unit based on demand and available production time. It gives the line a target pace.
What is run time?
Run time is the actual time a process needs to make products. This calculator uses cycle time and adjusted demand to estimate total run time.
What is pitch in production?
Pitch is a larger timing interval. It is usually takt time multiplied by the number of units in a container, cart, or batch.
Why should breaks be removed?
Breaks are not production time. Removing them gives a more honest view of the time available to meet customer demand.
How does downtime affect takt?
Downtime reduces effective available time. Less available time creates a shorter takt time and increases pressure on the process.
Why is yield included?
Yield accounts for scrap and rework. Lower yield means more units must be produced to deliver the required good units.
What does a negative gap mean?
A negative gap means cycle time is longer than takt time. The process may need added capacity, reduced waste, or better balancing.
Can this calculator handle multiple shifts?
Yes. Enter the number of shifts. The calculator multiplies shift time and planned losses to estimate total available time.
