What are the PMP Formulas?
Project management formulas are used in many project planning activities. These include, but are not limited, resource management, PMP cost management formulas and schedule estimation. They are also used in risk estimation activities such as EMV (earned-value management) and to monitor and control activities. This article will discuss the most important PMP formulas, and also provide a cheat sheet on PMP formulas.
PMI uses a variety of concepts in PMP Concepts, which are used alongside the PMP formulas. These concepts are used by PMI to assess your knowledge of basic project management terminology. These concepts include OPA and EEF, as well as other similar concepts. These concepts will also be covered in the PMP exam cheatsheet.

Why is it important to know PMP Formulas
The percentage of questions based on PMP formulas varies from 5% to 10%. This means that there are approximately 10 to 20 questions. It seems like a small amount. This is a sign that you need to rethink how you approach your exam strategy.

We will first provide PMP formulas that are related to the Critical Path method.
PMP Formulas #1: PERT Distribution
This PERT distribution can be divided into two types: triangular or beta.
PERT Triangular Distribution
It is one of the most important PMP formulas. We use it to calculate cost, duration, and resource estimates. First, you must determine the activity Optimistic, Most Likely (M), and Pessimistic estimates to calculate Estimated Activity Time (EAD). To estimate the activity duration, you can use PERT Triangular distribution. The PMP formula to calculate PERT Triangular distribution is as follows:
