## How do you calculate float in project management?

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 total float in CPM?

**Formulas for calculating Total Float and Free Float are as follows:**

- Total Float = LS – ES (it is also calculated by LF – EF)Free Float = Lowest ES of successors – EF.
- Free Float = Lowest ES of successors – EF.

## How is free float defined?

Free float**The number of shares in a company that are owned by many different shareholders and can be traded freely in the capital market**. The float refers to shares that are not owned by major shareholders, and can therefore be acquired and traded by the general public.

## How do you calculate float for each activity?

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 the free float of the following activity?

Free float is measured by subtracting the early finish (EF) of the activity from the early start (ES) of the successor activity. Free float represents the **amount of time that a schedule activity can be delayed without** delaying the early start date of any immediate successor activity within the network path.

## Can free float be greater than total float?

an activity’s Total Float can either be greater than or equal to Free Float. **Free Float can never be larger than its value** for Total Float. Each activity has its own total float value. Depending on the logic assigned to each activity, activities in a sequential string of logic have the same amount of total float.
