Enter the unadjusted project size, the technical factor, and the environmental factor into the UCP (Use Case Point) Calculator. The calculator will evaluate the UCP (Use Case Point). 

UCP (Use Case Point) Formula

The following formula is used to calculate the UCP (Use Case Point). 



  • UCP is the UCP (Use Case Point)
  • UUCW + UAW is the unadjusted project size 
  • TCF is the technical factor 
  • ECF is the environmental factor 

How to Calculate UCP (Use Case Point)?

The following steps outline how to calculate the UCP (Use Case Point).

  1. First, determine the unadjusted project size.
  2. Next, determine the technical factor. 
  3. Next, determine the environmental factor. 
  4. Next, gather the formula from above = UCP = (UUCW+UAW) * TCF * ECF.
  5. Finally, calculate the UCP (Use Case Point).
  6. 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.

unadjusted project size = 30

technical factor = 2

environment factor = 1.25

UCP = (UUCW+UAW) * TCF * ECF =  ?
