Free Float vs Total Float

Question

Accepted Answer

Free float is the amount of time an activity can be delayed without delaying the early start of the next activity. Total float is the amount of time an activity can be delayed without delaying the project end date.

Free float is specific to an activity and is calculated by subtracting the early start of the next activity from the early finish of the current activity.
Total float is the difference between the project end date and the late finish of an activity.
Free float can be used to optimize the schedule by identifying activities that can be delayed without affecting the overall project duration.
Total float can be used to identify activities that can be delayed without affecting the project end date.
For example, if an activity has a free float of 5 days, it can be delayed by up to 5 days without delaying the early start of the next activity.
If an activity has a total float of 10 days, it can be delayed by up to 10 days without delaying the project end date.
