# Planned Value (PV) vs Earned Value (EV) in Earned Value Management (EVM)

What’s the difference between Planned Value (PV), Earned Value (EV), and Actual Cost (AC) in Earned Value Management (EVM)? This is one of the most frequently asked question by people when they first come across the EVM concepts. I got this question in the email (not for the first time though), and my first instinct was to direct the sender to one of my blog posts. When I tried to look for the post, I was really surprised to know that though I have several posts on advanced EVM concepts such as ETC, EAC, TCPI etc., I don’t have any post on the most important EVM topic - Planned Value vs Earned Value. Better late than never, this is my attempt to cover this topic. We’ll also add Actual Cost (AC) to the mix, though most people don’t have problem understanding AC. As usual, we’ll learn by examples and exercises.

## PMBOK^{®} Guide, 5th Edition Definitions

Let’s look at the PMBOK^{®} Guide definitions of these terms first.

### Definition of Planned Value (PV)

The authorized budget assigned to scheduled work.

### Definition of Earned Value (EV)

The measure of work performed expressed in terms of the budget authorized for that work.

### Definition of Actual Cost (AC)

The realized cost incurred for the work performed on an activity during a specific time period.

The above definitions are pretty straight-forward and self-explanatory, right? Well, not for most beginners. Here are the simplified definitions sourced from BrainBOK PMP Flashcards. The keywords are __underlined__.

## Simplified Explanation

### What’s the difference between Planned Value (PV) and Earned Value (EV)?

Planned Value is the __estimated__ (monetary) value of the work __planned__ to be done, whereas Earned Value is the __estimated__ (monetary) value of the work __actually__ done.

### What’s the difference between Earned Value (EV) and Actual Cost (AC)?

Earned Value is the __estimated__ (monetary) value of the work __actually__ done, whereas Actual Cost is the amount __actually incurred__ for the work done.

### Trick to remember PV, EV and AC

PV => Estimated value / work planned to be done

EV => Estimated value / work actually done

AC => Actual cost incurred

## 5 Practice Questions on Earned Value Management

As such, the concepts are pretty straight forward but when applied to exam questions, things get tricky. Most people don’t have a problem in understanding Actual Cost (AC). Let’s apply the above trick to sample questions.

### Question 1

A project team had planned to accomplish $25,000 worth of work to date. It has spent $23,000 to date, and accomplished $20,000 worth of work. What is PV, EV and AC of the project as of today?

Based on this information, what is the __estimated__ value of the work __planned__ to be accomplished till date? It is $25,000. This is the PV.

What is the __estimated__ value of the work __actually__ accomplished? $20,000. This is the EV.

What is the amount __actually__ spent? $23,000. This is the AC.

Easy, isn’t it? Not so fast. Let’s consider a slightly more challenging problem.

### Question 2

A project has 10 work packages, each estimated to cost $100,000. The project team had estimated to complete 3 work packages at the end of three months. However, they managed to complete only 2 work packages in 3 months and spent $300,000. What is the PV, EV and AC of the project at the end of three months?

PV is the __estimated__ value of the work packages __planned__ to be completed in 3 month. 3 work packages were planned to be completed in 3 months. The estimated value of each work package is $100,000. Therefore, PV = 3 x $100,000 = $300,000.

EV is the __estimated__ value of work packages __actually__ completed. 2 work packages were actually completed and their value is 2 x $100,000 = $200,000

AC is the __actual cost incurred__ in 3 month i.e. $300,000.

Feeling better now? Let’s see how well you fare on the next one.

### Question 3

A project has a total budget of $100,000. Two months into the project, it has used $30,000 of its total budget to accomplish work that was estimated to cost $25,000. What is the PV, EV and AC?

What does $25,000 represent in this question? PV or EV? Apply the knowledge that you’ve acquired so far.

The work that was __estimated__ to cost $25,000 has already been accomplished. So, it is our EV, not PV. Tricky, isn’t it?

What is the PV? We do not have enough information in the question to determine PV for the project.

What is __actually spent__? $30,000. This is our AC.

Let’s continue.

### Question 4

A project has a total budget of $100,000 and is estimated to take 10 months to complete. After 5 months, it is estimated to complete 50% of its work at the cost of 60% of its budget, but it actually accomplished only $40,000 worth of the work, and spent 50% of its budget. What is the PV, EV and AC of the project after 5 months?

What is the __estimated__ value of work __planned__ to be completed in 5 months? It is 60% of the budget, which is $60,000. This is the PV.

What is the __estimated__ value of work __actually__ completed in 5 months? It is $40,000. This is the EV.

What is __actually spent__? 50% of the budget i.e. 50% of $100,000, which is $50,000. This is the AC.

Getting a hang of it now? Get ready for the final showdown.

### Question 5

A project has 10 work packages and each work package is estimated to take 1 month to complete. The first 5 work packages are estimated to cost $12,000 each, and the next 5 $8,000 each. At the end of month 5, the first 4 work packages were completed at the cost of $48,000. What is PV, EV and AC of the project at the end of month 5?

The following table lists the PV after each month.

**Month | PV ($)**

1 | 12,000

2 | 24,000

3 | 36,000

4 | 48,000

5 | 60,000

6 | 68,000

7 | 76,000

8 | 84,000

9 | 92,000

10 | 100,000

The PV after month 5 is $60,000.

4 work packages were __actually__ completed after month 5. Their __estimated__ value is 4 x $12,000 = $48,000. This is the EV.

AC is the cost __actually incurred__ i.e. $48,000.

I hope you found this post useful. If you have other EVM sample questions on PV, EV or AC that you have trouble with, post them in the comments below. I’ll try to address them. I also intend to cover all the topics listed on 80+ Commonly Confused Concepts for the PMP Exam in future.
