Earned Value (EV), Planned Value (PV), and Actual Cost (AC)

Earned Value (EV), Planned Value (PV), and Actual Cost (AC)

Introduction: Why This Matters

At the heart of Earned Value Management are three foundational metrics: Earned Value (EV), Planned Value (PV), and Actual Cost (AC). These values form the baseline inputs for every variance, index, and forecast calculation in project management. Without mastering these three, you cannot interpret cost performance, schedule health, or overall project efficiency.

On the PMP exam, many formula-based questions begin with EV, PV, and AC. If you misinterpret these inputs, every calculation that follows will be wrong. In real-world projects, confusion between these terms can cause poor decision-making, misleading reports, and a lack of credibility with stakeholders.

Purpose and Objectives

Primary Purpose: To build a clear understanding of EV, PV, and AC so that you can apply them with confidence in both exam and practice.

Key Objectives:

  • Define EV, PV, and AC and understand their roles in Earned Value Management.
  • Correctly calculate each value from project data.
  • Distinguish between budgeted and actual measures.
  • Interpret what each metric reveals about project performance.
  • Apply these values as inputs to variances, indices, and forecasts.

Overview

EV, PV, and AC are used together to answer three different questions. What work did we plan, what work did we actually earn, and what did it cost us to earn it?

  • Planned Value (PV): Budgeted value of the work you planned to have completed by a specific date.
  • Earned Value (EV): Budgeted value of the work you have actually completed by that date.
  • Actual Cost (AC): The real spend, pulled from financial records, for the work performed.

Characteristics

  • EV is always budget-based: EV reflects the planned budget for completed work, not what you spent.
  • PV is not spending: PV is planned work value, even if the team has spent more or less.
  • AC is direct data: AC is captured from costs incurred, not calculated from percent complete.
  • Percent complete matters: PV uses planned percent complete; EV uses actual percent complete.

Practical Example

Context: A university project involves building a new data analytics lab with a total budget at completion (BAC) of $2,000,000. After four months, planned progress is 50%, actual progress is 40%, and costs incurred are $1,200,000.

Activities:

  • Calculate PV: 50% planned completion gives PV = $1,000,000.
  • Calculate EV: 40% actual completion gives EV = $800,000.
  • Record AC: AC = $1,200,000 (costs incurred).

Outcome: The project is behind schedule because EV is lower than PV, and it is over budget because AC is higher than EV.

Common Pitfalls

Mixing up budgeted vs actual

  • Pitfall: Confusing EV with AC, treating EV as if it is money spent.
  • Prevention: Remember EV is budgeted value of completed work. AC is the real spend.

Misreading PV

  • Pitfall: Assuming PV is the cost to date or the amount spent.
  • Prevention: PV is planned value of work, regardless of actual spend.

Using the wrong percentage

  • Pitfall: Using actual percent for PV or planned percent for EV.
  • Prevention: PV uses planned percent. EV uses actual percent.

Sensei Tip : When you see the word budgeted, your mind should snap to EV or PV. When you see the word spent or incurred, that is AC.

Exam Alert : The exam loves the trap where AC is higher and the question tries to pull you into using AC in the EV formula. EV never uses AC. EV always uses actual percent complete × BAC.

Exam Lens

Patterns on the PMP Exam:

  • Expect questions where you are given BAC and percentages, then asked to compute EV or PV.
  • Many situational questions hinge on distinguishing between “budgeted” versus “actual.”
  • EV, PV, and AC questions often lead into variance or index calculations.

Sample Question

Question: A project has BAC = $600,000. At the 3-month mark, the project was planned to be 40% complete. In reality, only 30% of the work has been completed at a cost of $250,000. What are EV, PV, and AC?

  1. EV = $240,000; PV = $180,000; AC = $250,000
  2. EV = $180,000; PV = $240,000; AC = $250,000
  3. EV = $250,000; PV = $240,000; AC = $180,000
  4. EV = $240,000; PV = $180,000; AC = $180,000

Correct Answer: B. EV = 30% × 600,000 = $180,000; PV = 40% × 600,000 = $240,000; AC = $250,000 (given).

Quick Recap Table

Metric Formula Meaning Exam Watch Point
PV Planned % complete × BAC Work planned to be done Do not confuse with AC
EV Actual % complete × BAC Value of work accomplished Always budget-based, not actual
AC Recorded cost of actual work Money spent Comes from financial data

Key Takeaways

  • PV, EV, and AC are the foundation of all Earned Value Management calculations.
  • PV is based on planned progress, EV on actual progress, and AC on actual spending.
  • Confusing EV with AC is one of the most common mistakes on the PMP exam.
  • These three values enable variances, indices, and forecast calculations.
  • Accuracy in these inputs protects your credibility when reporting project performance.

Next Step

With PV, EV, and AC clearly defined, we will now explore Cost Variance (CV) and Schedule Variance (SV), which compare these values to reveal project health in cost and time.
