## Slack of Event in CPM Solution

STEP 0: Pre-Calculation Summary
Formula Used
Slack of an Event = Total Float-Free Float
S = TF0-FF0
This formula uses 3 Variables
Variables Used
Slack of an Event - (Measured in Second) - 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.
Total Float - (Measured in Second) - Total float is the period by which an activity can shift its timing without affecting the relevant schedule completion date.
Free Float - (Measured in Second) - 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.
STEP 1: Convert Input(s) to Base Unit
Total Float: 24 Day --> 2073600 Second (Check conversion here)
Free Float: 18 Day --> 1555200 Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
S = TF0-FF0 --> 2073600-1555200
Evaluating ... ...
S = 518400
STEP 3: Convert Result to Output's Unit
518400 Second -->6 Day (Check conversion here)
6 Day <-- Slack of an Event

Earliest Finish Time
Earliest Finish Time = Latest Finish Time-Total Float
Total Float in CPM
Total Float = Latest Finish Time-Earliest Finish Time
Latest Finish Time
Latest Finish Time = Total Float+Earliest Finish Time
Slack of Event given Independent Float
Slack of an Event = Free Float-Independent Float
Free Float given Indenpendent Float
Free Float = Independent Float+Slack of an Event
Independent Float used in CPM
Independent Float = Free Float-Slack of an Event
Total Float given Free Float
Total Float = Free Float+Slack of an Event
Free Float used in CPM
Free Float = Total Float-Slack of an Event
Slack of Event in CPM
Slack of an Event = Total Float-Free Float
Interfering Float
Interfering Float = Total Float-Free Float

## Slack of Event in CPM Formula

Slack of an Event = Total Float-Free Float
S = TF0-FF0

## What is Free Float?

Free Float, per definition, is the amount of time that the activity can be delayed before any successors will be delayed. Early Start/Finish times are used to calculate the Free Float values.

## What is Slack?

The Slack time for an activity is the time between its earliest and latest start time, or between its earliest and latest finish time. Slack is the amount of time that an activity can be delayed past its earliest start or earliest finish without delaying the project.
