TOPIC: QuestionFree Float Calculation

Free Float Calculation 5 years 1 hour ago #3056

 Khurram Hussain Visitor Dear Edward: Good day! For your first question, you can use either of the formulas to calculate the free float. Both formulas are correct. I am explaining the reason below, however I recommend just pick up one of them and stick with it till you pass your exam. Here is the proof that both formulas are the same: We know that, EF = ES + Duration, right? Now let’s start with your first formula and prove the second formula from it: = ES of next activity - ES of present activity - Duration of present activity = ES of next activity – (ES of present activity + Duration of present activity) = ES of the next activity – EF of present activity For the second and third questions: These formulas are correct if your starting point is zero. If your starting point is 1, the first formula will remain the same. However, the second formula will change to: Free float = ES of next activity – EF of present activity – 1 I highly recommend using the “day 0” approach as it resolves all of these confusions. Let me know if this resolves your confusion. Warm regards, Khurram Your e-mail address will never be displayed on the site. Check this box to be notified of replies to this topic.
