Here a good video with Takt Time Calculation examples applied in different contexts.
Takt Time Calculation Definition
Takt Time, if you see only the math, is a simple ratio:
Takt Time = Available Time / Customer Request
it is more difficult than this ratio.
The problems in this calculation typically are:
- The customer request is unclear and variable.
- Not all the people in the organization agree on the available time.
- The available time in different parts of the organization is not the same.
My suggestions to overcome this problem are:
- To set a standard available time.
- To print the standard on a big sheet.
- To make the standard visible into relevant offices.

Takt Time, Cycle Time and Lead Time
Other common mistakes are done because many people do not know the difference between Takt Time, Cycle Time and Lead Time.
Here there is a video I created to try to explain.
Takt is a word that derives from a German word and means rhythm.
the Takt Time is the “beat” of the production to satisfy the customer request.
It is calculated by the following formula:
Takt Time = Available Time / Customer Demand.
Cycle Time is the time we need to complete one task.
The Lead Time is the time we need to pass the entire “Value Stream”
The Cashier Metaphor
To remember these times I propose you to remember
“The Cashier Metaphor”.
The Cashier in the Supermarket has to perform his task in 5 minutes to avoid the queue to be longer and longer.
the Takt Time is equal to 5 minutes.
The average time to perform the task is 3 minutes.
the cycle time is equal to 3 minutes.
If I find a queue at the cash of 10 people I have to wait
10 * 3 minutes = 30 minutes
the lead time is equal to 30 minutes.
Time is the key to a Lean Company.
Knowing the difference between Takt Time, Cycle Time and Lead Time is a must.
The cashier metaphor will help you to remember.
