Slack Time Calculator


About Slack Time Calculator (Formula)

The Slack Time Calculator is a tool used to calculate the difference between the Latest Start Time (LST) and the Earliest Start Time (EST) of a project or task. The Slack Time formula is simply:


Where: ST = Slack Time LST = Latest Start Time EST = Earliest Start Time

Slack Time is a measure of the amount of time that a task or project can be delayed without delaying the completion of the entire project.

A positive slack time means that the task can be delayed without affecting the overall project timeline, while a negative slack time indicates that the task is critical to the project timeline and must be completed as soon as possible.

The Slack Time Calculator is used to determine the slack time of a task and ensure that project deadlines are met.
