How to Determine Total Float
The calculation for total float , which again is the time an activity can be delayed without affecting the final end date of the project, is:
Total Float = LS - ES or LF - EF
In the following example, the calculations for total float for tasks A and B are:
Total Float(A) = 6 - 3 or 11 - 8 = 3
Total Float(B) = 11 - 8 or 18 - 15 = 3
