Free Float Calculator
In project management, free float refers to how much time a task can be delayed without affecting the next dependent task. It’s useful for scheduling, identifying task flexibility, and managing project deadlines. The Free Float Calculator helps project managers analyze task dependencies and potential delays, ensuring smooth workflow management.
Knowing the free float of an activity allows for better resource allocation, preventing unnecessary delays and improving overall efficiency. It is commonly used in Critical Path Method (CPM) scheduling.
Formula:
To calculate free float (FF):

| Free Float (days or hours) | |
| Earliest Finish Time | |
| Earliest Start Time |
What is Free Float?
Free float is the amount of time an activity can be delayed before it affects the next task but not the overall project completion. If an activity has a free float of 3 days, it means you can delay it by 3 days without impacting the next task.
For example, in a construction project, if painting can start 3 days later without delaying flooring, then the free float is 3 days. The Free Float Calculator helps in tracking buffer time and ensuring all tasks stay on schedule.
Final Words:
In fact, understanding free float helps in efficient project scheduling. The Free Float Calculator makes it easy to track task flexibility, avoid bottlenecks, and keep projects running smoothly.
FAQs:
1. How to calculate free float?
Subtract the earliest start time (ES) from the earliest finish time (EF).
2. What is free float in project management?
It’s the extra time a task can be delayed without impacting the next dependent task.
3. How is free float different from total float?
Free float affects only one task, while total float considers the entire project schedule.
