Independent Float used in CPM Solution

STEP 0: Pre-Calculation Summary
Formula Used
Independent Float = Free Float-Slack of an Event
IF0 = FF0-S
This formula uses 3 Variables
Variables Used
Independent Float - (Measured in Day) - Independent Float is that portion of the total float within which an activity can be delayed to start without affecting the float of the preceding activities.
Free Float - (Measured in Day) - Free Float is the period by which an activity can shift in its timing without affecting the early start of any succeeding activity or event.
Slack of an Event - (Measured in Day) - Slack of an Event in a network is the difference between the latest event time and the earliest event time at its terminal point or node.
STEP 1: Convert Input(s) to Base Unit
Free Float: 18 Day --> 18 Day No Conversion Required
Slack of an Event: 6 Day --> 6 Day No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
IF0 = FF0-S --> 18-6
Evaluating ... ...
IF0 = 12
STEP 3: Convert Result to Output's Unit
1036800 Second -->12 Day (Check conversion ​here)
FINAL ANSWER
12 Day <-- Independent Float
(Calculation completed in 00.004 seconds)

What is Independent Float?

Independent Float is defined as the amount of time an activity's start time can be delayed without affecting the earliest start time of any successors. So independent float is the delay in any project tasks that have no bearing on the early finish date of the project.

What is Tail Event Slack?

The Tail Event Slack of an activity in a network is the slack at the tail (or starting point) of an activity. In other words, tail event slack of an activity in a network is the difference between the latest event time and the earliest event time at its tail (or starting point or node).

How to Calculate Independent Float used in CPM?

Independent Float used in CPM calculator uses Independent Float = Free Float-Slack of an Event to calculate the Independent Float, The Independent Float used in CPM formula is defined as the excess time available as the preceding activity ends as late as possible and the succeeding activity starts as early as possible. Here slack is tail event slack. Independent Float is denoted by IF0 symbol.

How to calculate Independent Float used in CPM using this online calculator? To use this online calculator for Independent Float used in CPM, enter Free Float (FF0) & Slack of an Event (S) and hit the calculate button. Here is how the Independent Float used in CPM calculation can be explained with given input values -> 0.000139 = 1555200-518400.

FAQ

What is Independent Float used in CPM?
The Independent Float used in CPM formula is defined as the excess time available as the preceding activity ends as late as possible and the succeeding activity starts as early as possible. Here slack is tail event slack and is represented as IF0 = FF0-S or Independent Float = Free Float-Slack of an Event. Free Float is the period by which an activity can shift in its timing without affecting the early start of any succeeding activity or event & Slack of an Event in a network is the difference between the latest event time and the earliest event time at its terminal point or node.
How to calculate Independent Float used in CPM?
The Independent Float used in CPM formula is defined as the excess time available as the preceding activity ends as late as possible and the succeeding activity starts as early as possible. Here slack is tail event slack is calculated using Independent Float = Free Float-Slack of an Event. To calculate Independent Float used in CPM, you need Free Float (FF0) & Slack of an Event (S). With our tool, you need to enter the respective value for Free Float & Slack of an Event and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
