Total Float in CPM Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Float = Latest Finish Time-Earliest Finish Time
TF₀ = LFT-EFT
This formula uses 3 Variables

Variables Used

Total Float - (Measured in Day) - Total float is the period by which an activity can shift its timing without affecting the relevant schedule completion date.
Latest Finish Time - (Measured in Day) - Latest Finish Time is the latest time at which the activity can be completed without delaying the project.
Earliest Finish Time - (Measured in Day) - Earliest Finish Time is the time of an activity that occurs if the activity starts at the earliest start time and takes an estimated time t to complete the activity.

STEP 1: Convert Input(s) to Base Unit

Latest Finish Time: 50 Day --> 50 Day No Conversion Required
Earliest Finish Time: 26 Day --> 26 Day No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

TF₀ = LFT-EFT --> 50-26

Evaluating ... ...

TF₀ = 24

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 Float?

Float, sometimes called slack, is the amount of time an activity, network path, or project can be delayed from the early start without changing the completion date of the project.

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 in CPM?

Total Float in CPM calculator uses Total Float = Latest Finish Time-Earliest Finish Time to calculate the Total Float, The Total Float in CPM formula is defined as the time span by which the starting or finishing time can be delayed without delaying or affecting the overall project. The formula above is also valid as TF=LST-EST. Total Float is denoted by TF₀ symbol.

How to calculate Total Float in CPM using this online calculator? To use this online calculator for Total Float in CPM, enter Latest Finish Time (LFT) & Earliest Finish Time (EFT) and hit the calculate button. Here is how the Total Float in CPM calculation can be explained with given input values -> 0.000278 = 4320000-2246400.

FAQ

What is Total Float in CPM?

The Total Float in CPM formula is defined as the time span by which the starting or finishing time can be delayed without delaying or affecting the overall project. The formula above is also valid as TF=LST-EST and is represented as TF₀ = LFT-EFT or Total Float = Latest Finish Time-Earliest Finish Time. Latest Finish Time is the latest time at which the activity can be completed without delaying the project & Earliest Finish Time is the time of an activity that occurs if the activity starts at the earliest start time and takes an estimated time t to complete the activity.

How to calculate Total Float in CPM?
