Total Float Solution

STEP 0: Pre-Calculation Summary
Formula Used
Total Float = Late Finish Time-(Early Start Time+Duration of Activity)
TF0 = LFT-(EST+dur)
This formula uses 4 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.
Late Finish Time - (Measured in Second) - Late Finish Time is the latest point in time when the scheduled activity can finish so as not to delay the project completion date or any constraint.
Early Start Time - (Measured in Second) - Early Start Time is the earliest point in time when the scheduled activity can begin.
Duration of Activity - (Measured in Second) - Duration of activity is the total number of work periods required to accomplish the work of the activity.
STEP 1: Convert Input(s) to Base Unit
Late Finish Time: 57 Day --> 4924800 Second (Check conversion ​here)
Early Start Time: 19 Day --> 1641600 Second (Check conversion ​here)
Duration of Activity: 34 Day --> 2937600 Second (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
TF0 = LFT-(EST+dur) --> 4924800-(1641600+2937600)
Evaluating ... ...
TF0 = 345600
STEP 3: Convert Result to Output's Unit
345600 Second -->4 Day (Check conversion ​here)
FINAL ANSWER
4 Day <-- Total Float
(Calculation completed in 00.004 seconds)

To use this online calculator for Total Float, enter Late Finish Time (LFT), Early Start Time (EST) & Duration of Activity (dur) and hit the calculate button. Here is how the Total Float calculation can be explained with given input values -> 4.6E-5 = 4924800-(1641600+2937600).

FAQ

What is Total Float?
Total float is the period by which an activity can shift its timing without affecting the relevant schedule completion date and is represented as TF0 = LFT-(EST+dur) or Total Float = Late Finish Time-(Early Start Time+Duration of Activity). Late Finish Time is the latest point in time when the scheduled activity can finish so as not to delay the project completion date or any constraint, Early Start Time is the earliest point in time when the scheduled activity can begin & Duration of activity is the total number of work periods required to accomplish the work of the activity.
How to calculate Total Float?
Total float is the period by which an activity can shift its timing without affecting the relevant schedule completion date is calculated using Total Float = Late Finish Time-(Early Start Time+Duration of Activity). To calculate Total Float, you need Late Finish Time (LFT), Early Start Time (EST) & Duration of Activity (dur). With our tool, you need to enter the respective value for Late Finish Time, Early Start Time & Duration of Activity and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Total Float?
In this formula, Total Float uses Late Finish Time, Early Start Time & Duration of Activity. We can use 1 other way(s) to calculate the same, which is/are as follows -
  • Total Float = Late Start Time-Early Start Time
