When preparing for the Project Management Professional (PMP) exam, understanding and mastering the essential formulas is crucial. In this article, we will dive into the 15 PMP exam formulas you need to know for success. Whether you are new to project management or looking for a refresher, this comprehensive guide will provide you with the knowledge and tools to confidently tackle calculation-based questions in the PMP exam.
The 15 PMP Exam Formulas You Need To Know
Knowing these formulas will prove a great boon when it comes to answering the math questions on the PMP exam. However, it’s important to note first that these formulas fall under two classification categories:
- Critical Path Method (CPM)
- Earned Value Management (EVM)
So let’s break down the formulas within those two categories so you can get the full context.
1. Earned Value Management (EVM) Formulas
Learn the formulas for calculating key earned value management metrics such as Schedule Variance (SV), Cost Variance (CV), Schedule Performance Index (SPI), and Cost Performance Index (CPI).
2. Critical Path Method (CPM) Formulas
Understand the critical path method formulas, including Early Start (ES), Early Finish (EF), Late Start (LS), and Late Finish (LF), to effectively analyze project schedules and identify critical activities.
3. Probability and Impact Matrix Formulas
Explore the formulas used to calculate Risk Impact and Probability, and how to determine Risk Exposure and Risk Priority based on these values.
4. Communication Channels Formula
Understand the formula for calculating the number of communication channels in a project, which helps in estimating communication overhead and managing stakeholder interactions.
5. Three-Point Estimating Formulas
Discover the formulas for Three-Point Estimating, including the Expected Value (EV), Pessimistic Value (PV), Optimistic Value (OV), and Standard Deviation (SD), to improve accuracy in project duration and cost estimation.
6. Cost and Schedule Performance Formulas
Learn the formulas to calculate Cost Performance Index (CPI), Schedule Performance Index (SPI), Estimate at Completion (EAC), and Estimate to Complete (ETC) to monitor project performance and predict future outcomes.
7. Present Value (PV) and Future Value (FV) Formulas
Explore the formulas for calculating Present Value (PV) and Future Value (FV) of cash flows, which are essential in financial analysis and decision-making.
8. Return on Investment (ROI) Formula
Understand the formula to calculate Return on Investment (ROI), a key financial metric used to evaluate the profitability and value of a project or investment.
9. Depreciation Formulas
Gain knowledge of the formulas used to calculate various depreciation methods such as Straight-Line Depreciation, Double Declining Balance, and Sum-of-the-Years’-Digits.
10. Expected Monetary Value (EMV) Formula
Learn the formula for calculating Expected Monetary Value (EMV), which combines the probability and impact of risks to assess the overall risk exposure in a project.
11. Cost of Quality (COQ) Formula
Understand the formula to calculate the Cost of Quality (COQ), which helps in evaluating the cost of ensuring quality and identifying opportunities for improvement.
12. Payback Period Formula
Explore the formula for calculating the Payback Period, a financial metric used to assess the time required to recover the initial investment in a project or investment.
13. Variance and Standard Deviation Formulas
Understand the formulas for calculating Variance and Standard Deviation, which are important statistical measures used to assess project performance and determine the spread of data.
14. Expected Rate of Return (ERR) Formula
Learn the formula to calculate the Expected Rate of Return (ERR), which is used to evaluate the attractiveness and potential profitability of an investment or project.
15. Float and Slack Formulas
Explore the formulas for calculating Float and Slack, which help in understanding the flexibility and scheduling buffers available in a project.
PMP Cheat Sheet: Knowing the Most Frequent PMP Concepts
As we said above, it’s time to go over PMP concepts, as well. These concepts are frequently used in the PMP exam and the world of project management in general.
- Enterprise Environmental Factors (EEF)
- Organizational Process Assets (OPA)
- Project Management Plans
Understanding PMP Exam Formulas and PMP Concepts
These PMP formulas aren’t just relevant to the exam itself. They can help you in your day to day routine as a project manager. These formulas are designed to help you hack resource management, cost management, schedule estimation, and risk estimation. Consider, for instance, earned value management (EVM), which is used to help ensure that your earnings stay on track.
PMP concepts are slightly different. These concepts help you get into the mindset behind the PMP exam, drawing on theories that PMI frequently brings into the PMP exam. PMP concepts are made to ensure that you understand the basic project management vocabulary, such as EEF, OPA, and more. It’s important to cover these as well while prepping for the PMP exam.
Why Are PMP Exam Formulas Important?
PMP exam formula questions make up a relatively small portion of the PMP exam — usually about 5-10%. However, these questions can be a significant help when it comes to passing the exam. Formula based questions vary in difficulty: some are rather straightforward, while others are quite complex.
This means they will vary in points awarded. If you have the PMP exam formulas memorized, you can easily ace those questions, which will give you a big boost towards passing the exam as a whole. It’s a good idea to research the PMP exam pass rate before you take the exam to learn more.
So without further ado, let’s discuss the PMP exam formulas.
Subsidiary Management Plans
A project manager should have a plan for everything. These are the management plans within your management plan, including:
- Scope Management
- Requirements Management
- Schedule Management
- Cost Management
- Quality Management
- Resources Management
- Communications Management
- Risk Management
- Stakeholder Engagement
- Baselines
Your baselines include your approved cost, scope, and schedule management plans. These will be used as a basis for the performance of the project. To break this down further, that means:
- Scope Baseline: The approved scope statement and work breakdown structure (WBS) as well as terminology
- Cost Baseline: The approved budget for the project within a certain time
- Schedule Baseline: The approved schedule for the project
- Additional Components
So what’s left over?
- Change Management. This settles how change requests will be handled throughout the project.
- Configuration Management: This determines how the project will be itemized and indexed to make sure it’s still going strong.
- Performance Measurement Baseline: This combines scope, schedule, and cost and compares it to the actual process of the project.
- Project Lifecycle: This measures the length of time the project will take, including each phase.
- Development Approach: This determines what sort of model will be used, such as agile, iterative, predictive, and so on.
- Management Reviews: Finally, the project manager reviews the project with stakeholders to get a clear sense of performance and make any changes.
