Total Float given Free Float Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Float = Free Float+Slack of an Event
TF₀ = FF₀+S
This formula uses 3 Variables

Variables Used

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.
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.

STEP 1: Convert Input(s) to Base Unit

Free Float: 18 Day --> 1555200 Second (Check conversion here)
Slack of an Event: 6 Day --> 518400 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

TF₀ = FF₀+S --> 1555200+518400

Evaluating ... ...

TF₀ = 2073600

STEP 3: Convert Result to Output's Unit

2073600 Second -->24 Day (Check conversion here)

FINAL ANSWER

24 Day <-- Total Float

(Calculation completed in 00.004 seconds)

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.

How to Calculate Total Float given Free Float?

Total Float given Free Float calculator uses Total Float = Free Float+Slack of an Event to calculate the Total Float, The Total Float given Free Float formula is defined as the maximum allowable delay in a project activity, while Free Float is the delay without impacting successor activities. Total Float is denoted by TF₀ symbol.

How to calculate Total Float given Free Float using this online calculator? To use this online calculator for Total Float given Free Float, enter Free Float (FF₀) & Slack of an Event (S) and hit the calculate button. Here is how the Total Float given Free Float calculation can be explained with given input values -> 0.000278 = 1555200+518400.
