What is Free Float?

A free float is defined as the difference between the early finish date of the activity and the early start date of the subsequent activity. It represents the amount of time that an activity can be delayed without delaying the early start of any subsequent activities.

Example Calculation

Using the formula to calculate Free Float (FF):

\[ FF = 10 - 12 = -2 \text{ days} \]

The Free Float is -2 days, indicating that the activity is behind schedule.
