Free float is how long an activity can be delayed without delaying the Early Start of its successor. You can calculate the free float by subtracting the Early Finish Date of the activity from the Early Start Date of the next activity.

How do you calculate total float and free float?
To calculate total float, subtract the task’s earliest finish (EF) date from its latest finish (LF) date. It looks like this: LF – EF = total float. Alternately, you can subtract the task’s earliest start (ES) date from its latest start (LS) date, like this: LS – ES = total float.
How do you calculate float time?
Float time is the amount of time a task can be delayed without it causing a delay to other tasks in the project. We calculate this by finding the latest start time and subtracting the earliest start time.
What is free float in schedule?
In project management, float or slack is the amount of time that a task in a project network can be delayed without causing a delay to: subsequent tasks (“free float”) project completion date (“total float”).
How do you calculate free float?
Free-float methodology is a method of calculating the market capitalization of a stock market index’s underlying companies. Using this methodology, the market capitalization of a company is calculated by taking the equity’s price and multiplying it by the number of shares readily available in the market.
What is TF and FF?
Total Float vs Free Float in Scheduling
Basically, TF and FF are two critical path method terms. You use both of them while analyzing the project network diagrams and determining the critical path of a project. Although they sound quite similar, they refer to two different calculation method.
What is free float in CPM?
Free float is the amount of time an activity can be delayed without delaying the early start of any immediate successor activity.
What is free float in critical path method?
Free Float is the amount of time that an activity can be delayed without delaying the early start date of any successor activity.
What is free float and independent float?
Total Float – Amount of time that an activity may be delayed from early start without delaying the project finish date. Free Float – Amount of time a task can be delayed without delaying the early start of its successor.
How do you calculate float time in critical path analysis?
To determine float, follow this process:
- Find the second longest sequence of activities in the network diagram.
- Subtract its total duration from the duration of the critical path sequence.
- The difference between the two durations will give you the float for each activity in the second sequence.
How do you calculate free float Mcq?
Slack and Float MCQ Question 2 Detailed Solution
Free float is the portion of total float by which an activity can be delayed without affecting succeeding activity. Free float is also equal to total float minus head event slack.
How do you calculate float on a network diagram?
In summary, Find the second-longest sequence of activities in the network diagram. Subtract its total duration from the duration of the critical path sequence. The difference between the two duration will give you the float for each activity in the second sequence.
What is free float in Primavera?
In Primavera P6, there are two important values: Total Float and Free Float.Total Float: is the amount of time an activity can be delayed without delaying the Project Finish Date. Free Float: is the amount of time an activity can be delayed without delaying its Successor Activity Finish Date.
How is free float defined quizlet?
Free float is defined as “the number of time units that allow an activity to be delayed without delay the Early Start (ES) of its successors.” A critical activity is an activity with zero free float. Response Feedback: Critical activity is an activity with zero TOTAL float, not FREE float.
What is free float PMP?
Free float is an amount of time that a schedule activity can be delayed without delaying the early start of any immediately following schedule activities.
Is total float higher than free float?
Primavera did it again. How can that Free Float is Higher than Total Float (for activities with Total Float >=0). It is sufficient that, inside the schedule, you have some activities with negative Total Float.
What is CPM and PERT technique?
PERT is that technique of project management which is used to manage uncertain (i.e., time is not known) activities of any project. CPM is that technique of project management which is used to manage only certain (i.e., time is known) activities of any project.
How do you calculate slack and free slack?
Total slack is calculated as the smaller value of the late finish minus the early finish when compared to early start minus the late start. Total slack can be either positive or negative. If total slack is positive, then it indicates the amount of time the project can be delayed without extending the project.
How is free slack calculated in MS Project?
Use the Detail Gantt view to find slack (float)
- Click View > Other Views > More Views.
- In the Views list, double-click Detail Gantt.
- Click View > Tables> Schedule.
- Click a task and view its slack values in the Free Slack and Total Slack fields.
Can critical path have float?
Critical path activities can have float; hence the critical path can have float.
