Cycle Time vs Takt
What cycle time do you need to meet demand?
Compares the actual cycle time with the required pace (takt) and shows the headroom or shortfall.

How this tool works
Inputs, units and where to find them
| Input | Unit | Typical source |
|---|---|---|
| Available time | min | Net available production minutes |
| Required output | units | Units required in the same period |
| Current cycle time | min/unit | Measured cycle time (representative, not best) |
What each input means
Open an input to see what it is, its units, the worked example and the common mistakes, with a small diagram.
What this means: Available time
- What it is
- The net production minutes in the period after breaks and planned stops, used to work out the required pace.
- Units and format
- Enter a number in min: minutes. The form accepts 0 min or more.
- Example
- The form opens with 420 min as a worked example. It is an illustration, not a recommended value: replace it with your own figure.
- Effect on the result
- More time lengthens the required cycle and increases headroom.
- Get it right
- Use the same period as the required output, for example one shift.
What this means: Required output
- What it is
- The number of units that must be completed in the same period as the available time.
- Units and format
- Enter a number in units: a count of units. The form accepts 1 units or more.
- Example
- The form opens with 140 units as a worked example. It is an illustration, not a recommended value: replace it with your own figure.
- Effect on the result
- Higher output shortens the required cycle and reduces headroom.
- Get it right
- Use customer demand for the period, not the output you hope to reach.
What this means: Current cycle time
- What it is
- The time the station currently takes per unit, measured over a representative run including normal handling.
- Units and format
- Enter a number in min/unit: min/unit. The form accepts 0 min/unit or more.
- Example
- The form opens with 3.4 min/unit as a worked example. It is an illustration, not a recommended value: replace it with your own figure.
- Effect on the result
- Headroom falls minute for minute as actual cycle time rises.
- Get it right
- Use a typical cycle from several observations, not the fastest one.
Method and formulas
- Required cycle (takt) = available ÷ demand
- Headroom = takt − actual cycle
- Output = available ÷ actual cycle
Limitations
- Single station; no variation or downtime
Typical uses
- Checking whether a cell can meet demand
- Setting cycle-time improvement targets
Who it is for
- Production engineers
- Supervisors
What you get
- MEETS PACE or TOO SLOW
- Headroom and output at actual cycle
Interpreting the result
- Less than 10% headroom is fragile in practice
