A takt time calculator is simply a spreadsheet with the takt time calculations already programmed in.
It is most useful for people who don’t routinely calculate takt time. The takt time calculator should take people through all the steps of determining takt time.
Takt time calculators vary—some do it by shift, some by day. In any case, the calculator should take out the non-working time (meetings, breaks, etc.)
The most important part is to make sure that the takt time calculator breaks demand out the same way as the time (i.e. if the time is looked at per shift, the demand should be looked at per shift.)
We have attached a very basic takt time calculator for our registered users to download. (Registration is free and takes less than a minute to do. Check out the registered user benefits or click the link to become a registered user now.)

i have 10 hrs shift schedule daily and we are scheduled to process 150 pcs of raw materials a day,total of 1030 mins before we finish the whole process,how many is the takt time & needed operators a day.
The takt time part of your question is relatively easy. Using the calculator, with 35 minutes pulled out for breaks/meetings/etc., you have 565 minutes of working time divided by 150 units per shift for a takt time of 226 seconds or 3.77 minutes.
The second part of your question needs more information. Typically, you divide total cycle time by takt time to get the number of operators you need, but in your case that would yield 273 people, which seems high. Either that cycle time is for a batch process, or it includes waiting time. Either way, the calculation is missing something.
I have a TAKT time of 925.7 seconds. 2 (10 hour)shifts with demand of 70 units.
I need to add 3.75 parts per shift so how many people should I add to my line.
My line is always 3 people.
The basic formula for the number of people is the total cycle time divided by the takt time. So if the takt was 100 seconds, and your total cycle time was 5 minutes (300 seconds), you would need 300/100 people. For your situation, you’d have to add up the cycle time of the three people on your line and divide that by the new takt time you get when you increase the demand (numerator in the takt time calculation.)
The problem is that the calculation is in a perfect world. The line would need to be 100% balanced, and 100% efficient. You’ll have to adjust the number of people required based on those factors.
Hope that helps answer your question.
