Takt Time Calculator

Shift Duration (in Hours):  
Lunch Time (in Hours):  
Break Time (in minutes):  
Number of Breaks:  
Number of parts required by Customer:
(Customer Demand)
* Net Shift Time (minutes):  
** Takt time:  

*Net Shift Time (minutes)= (Shift Duration x 60) - (Lunch Time x 60) - (Break time x Number of breaks)
**Takt time = Net Shift time/Customer Demand

Takt time: It is the rate at which the process needs to produce to meet customer demand. Takt time is calculated using an equation. Takt time is also called rhythm or beat.
Takt time= (Net available time in a shift)/Customer demand in the shift
Takt time could change every shift based on the changes in customer demand and net available time. Takt time cannot be improved as it is directly calculated from customer demand and available time.

Now let us look at takt and cycle time with an example. A Cookie making company has three process steps for making cookies.
1) Dough making
2) Forming cookies
3) Baking
4) Packing

The time required for 1 cookie to come off the line is 5hrs i.e. cycle time is 5hrs. Each process step has individual cycle times too which we will not consider for this example.
The company runs an 8hour shift with 30min for lunch and two 10min breaks.
Customer demand for the first shift today is 50,000 cookies.


Takt time = {((8 x 60)- 30-(2x10))/50000} =0.0086 minutes/cookie

To meet customer demand each process step should be operating slightly under the takt time. This means that a cookie must be coming off of each process step (dough making, forming, baking and packing) is less than 0.0086 minutes or 0.516 seconds. The rhythm for the process for the first shift today needs to be set at 0.516 seconds.
If cookies are made in batches then production needs to plan the batches in such a way that they have a cookie every 0.516seconds.
