Enter the total cycle time (min) and the unit product time (min) into the Calculator. The calculator will evaluate the Assembly Time. 

Assembly Time Formula



  • AT is the Assembly Time (minutes)
  • TCT is the total cycle time (min)
  • UPT is the unit product time (min)

To calculate Assembly Time, subtract the unit product time from the total cycle time.

How to Calculate Assembly Time?

The following steps outline how to calculate the Assembly Time.

  1. First, determine the total cycle time (min). 
  2. Next, determine the unit product time (min). 
  3. Next, gather the formula from above = AT = TCT – UPT.
  4. Finally, calculate the Assembly Time.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total cycle time (min) = 50

unit product time (min) = 45
