PMP® Formulas and calculations take up roughly 10% of the PMP® exam. It’s hard to say the exact number of calculation questions that you will get on your exam.

When you enter the Prometrics testing center and begin your exam, the software randomly selects 200 questions for you. Thus, you can be sitting next to someone who is also writing their PMP® exam, but the two of you will get completely different exams.

To me, the PMP® formulas are easy marks. All you need to do is memorize the formulas and then “plunk” in the numbers from the questions.

Let’s look at the complete list of 17 PMP® formulas you need to know for your exam along with a description for each. At the end of this article, there will be an option for you to download this guide.

(It is a good idea to include all of these formulas on your “cheatsheet” before your PMP® exam. To learn how to create your own cheatsheet, click here.)
