Float – Slack – Free Time:
The float or slack or free time is the amount of time by that an activity can be delayed or extended without delaying the project completion time.

Interfering Float:
The part of the total float which cause a reduction in the float of the successor activities is called interfering float.

Interfering Float =
= (Lf of activity – Es of Successor) or 0 (zero), whichever is larger

Total Float:
The total float of an activity represents the amount of time by which the activity can be delayed without delaying the project completion date. That means total float refers to the amount of free time associated with an activity which can be used before, during or after the performance of the activity for the purpose of delaying the completion of the activity or extending the time consumption of the activity.

Total Float = Lf – Ef = Ls – Es = Lf – Es – Duration of the activity

Interfering Float + Free Float = Total Float
