Earned Value Management: How to Calculate It?

Creating a good project plan is the first step in successful project management, but the hard part comes once you start implementing it and need to constantly sanity check whether you are progressing as expected. This is where Earned Value Management comes in – it helps you to assess not only if you’re late or early, but also how you’re tracking against your budget and effort.

In this article, you’ll learn all about earned value management – the benefits, how to calculate, the main metrics, real-life examples, and the best tools. Keep reading, or you’ll miss out on important stuff.

What Is Earned Value Management?

Earned value management (EVM) is a technique that is used to measure a project’s performance and progress. It helps project managers to make informed decisions during a project’s lifecycle. There is more than one way how project managers can calculate project progress. Quite often such measurement falls under the subjective approach to set completion percentage for each project task without any ground rules.

The bad part is that each individual will treat progress differently and will be driven sometimes by contradicting incentives. This is why it is important to use a well-defined, tested, and proven technique.

What Are the Benefits of Earned Value Management (EVM)?

While like any technique EVM has its own cost of implementation, it does bring the following advantages:

• Objective way to measure project’s performance
• Objective indication of better or worse performance on more than one aspect of project (schedule, budget, work)
• Time focused to help assesing impact of changes to project
• Well proven technique by many research studies as well as commercial projects
• Ability to visualize and present a constructive evaluation of project’s performance versus how it was planned

Requirements for Implementing Earned Value Management

To successfully use the EVM technique there are minimum requirements to have:

• A project plan which identifies what needs to be accomplished
• Estimate or valuation of planned work, called planned value (PV)
• Earning rules to quantify the progress of work, called earned value (EV)
• Actual Cost calculations, called Actual Cost of Work Performed (ACWP) or just Actual Cost (AC)
• Plot of project cumulative costs vs time. To visualize early and late date curves

The requirements are not limited to the above ones and usually are extended in case of larger or complex projects. Examples of additional things to have:

• Indicators of cost performance (over or under budget)
• Indicators of schedule performance (behind or ahead of schedule)

Earned Value VS Planned Value VS Actual Cost

At first, it may seem all of these three terms are quite similar, but there are key differences that separate them.

• Planned Value is the estimated monetary value for work that has been planned.
• Earned value is the estimated monetary value for the work that has already been completed.
• Actual cost is the actual value of the work that has been completed.

So when comparing earned value vs planned value vs actual cost, we are looking at the same period of time from three different perspectives:

• What value was estimated for the work that was planned to be completed – PV
• What value was estimated for the work that has actually been completed – EV
• What is the actual value of the work that has been completed – AV

PV, EV, and AC are key elements that can be used to calculate and measure projects performance over time.

EVM vs. Traditional Tracking

Earned value management is a more precise and objective way to track project performance compared to traditional percentage-based tracking.

The basic % completion method relies on subjectivity – teams estimate how much work has been completed. EVM, on the other hand, gives quantifiable data and integrates cost, schedule, and scope. This way you get a more accurate evaluation of a project’s actual progress relative to its planned value.

The traditional tracking can sometimes lead to faulty reports because each team member might have a different perception of what is “completed” work. EVM, on the other hand, uses clear formulas to measure earned value, and offers more reliable insights into whether a project is on track, underperforming, or exceeding expectations.

How to Calculate Earned Value?

EV = Total Project Budget * Completed % of Project Budget

Earned Value Management Formulas

There are many more formulas than just a single EV. Closer to the final list looks like the following table.

If you need to run these formulas daily, it could seem tedious it is why popular project management tools provide those calculations out of the box. Compare the best project management tools.

SPI vs. CPI in Earned Value Management: Formulas, Examples & Key Differences

Now that you know the key EVM formulas, let’s take a closer look at the two most important metrics: Schedule Performance Index (SPI) and Cost Performance Index (CPI). In short, they tell you whether your project is on time and on budget.

Definitions & Formulas

Example

Scenario: A $100K software project with:

• Planned Value (PV): $50K (50% work planned by now)
• Earned Value (EV): $40K (40% work actually done)
• Actual Cost (AC): $60K

Calculations:

• SPI = 40K/40K/50K = 0.8 (Behind schedule)
• CPI = 40K/40K/60K = 0.67 (Severely over budget)

Actionable insight:

• Focus on cost control (CPI is worse than SPI).
• Investigate why work is 20% slower and 33% more expensive than planned.

SPI vs. CPI: Which Matters More?

When managing a project, it’s important to understand the balance between cost efficiency and schedule adherence. So, what should you do when one is on track but the other isn’t? Let’s break down what SPI vs. CPI really means for your next move.

• Behind schedule but under budget (SPI < 1, CPI > 1)? Speed up work without adding costs.
• Ahead of schedule but over budget (SPI > 1, CPI < 1)? Re-evaluate resource allocation.

Real-World EVM Example: Renewable Energy Case Study

Let’s say you are building a wind power plant – a $500,000 wind power plant construction with 10-month timeline. After 5 months, you see key metrics:

• Planned Value (PV): $250,000 (50% of timeline elapsed)
• Earned Value (EV): $255,000 (work actually completed)
• Actual Cost (AC): $220,000 (funds spent)

Project performance so far indicates steady progress ahead of schedule:

• CPI = 1.16 (EV/AC): Project is under budget.
• SPI = 1.02 (EV/PV): Project is slightly ahead of schedule.

Here’s a visual demonstration – a Gantt chart highlighting project milestones, task progress, and the current timeline status.

The project’s Gantt chart shows steady progress with:

• Clear task completion tracking
• Automatic SPI calculation
• Real-time budget monitoring

Summary

There are many project management methodologies as well as stand-alone tools to guide project managers to successful projects. EVM is just one of the tools and should be used because of its benefits while rationally assessing other existing alternatives. All in all, it is still preferred to use such techniques to remove people’s bias toward different outcomes and guard stakeholder interests internally as well as externally.
