Earned Value Analysis: Meaning, Formula & Examples

Introduction

Managing project budgets and schedules effectively is a key challenge for project managers. Earned Value Analysis (EVA) is a powerful technique in project management that helps track cost and schedule performance, ensuring that projects stay on track. In this guide, we will cover the Earned Value Analysis meaning, formulas, examples, and how to apply EVA in real-world scenarios.

What is Earned Value Analysis?

Earned Value Analysis Meaning

Earned Value Analysis (EVA) is a project management technique used to measure project performance by comparing the planned progress with actual progress. It integrates scope, schedule, and cost data to provide a clear picture of project health.

Why is EVA Important?

1. Helps identify budget overruns early

2. Measures schedule efficiency

3. Improves project forecasting

4. Supports data-driven decision-making

Key Components of Earned Value Analysis

To effectively use EVA, you need to understand its three core elements:

1. Planned Value (PV): The budgeted cost of work scheduled at a given point.

2. Earned Value (EV): The budgeted cost of work actually completed.

3. Actual Cost (AC): The total cost incurred for the completed work.

Earned Value Analysis Formula & Calculations

Using the above metrics, we can calculate key EVA indicators:

Cost Variance (CV)

CV = EV - AC

If CV > 0: The project is under budget.

If CV < 0: The project is over budget.

Schedule Variance (SV)

SV = EV - PV

If SV > 0: The project is ahead of schedule.

If SV < 0: The project is behind schedule.

Cost Performance Index (CPI)

CPI = EV / AC

If CPI > 1: The project is cost-efficient.

If CPI < 1: The project is over budget.

Schedule Performance Index (SPI)

SPI = EV / PV

If SPI > 1: The project is progressing faster than planned.

If SPI < 1: The project is behind schedule.

Earned Value Analysis Example

Scenario:

A construction project has a total budget of $500,000 and is scheduled to be completed in 10 months. After 5 months, the following data is available:

1. Planned Value (PV): $250,000

2. Earned Value (EV): $200,000

3. Actual Cost (AC): $220,000

Step-by-Step EVA Calculations:

Cost Variance (CV) = EV - AC
CV = $200,000 - $220,000 = -$20,000
→ The project is $20,000 over budget.

Schedule Variance (SV) = EV - PV
SV = $200,000 - $250,000 = - $50,000
→ The project is $50,000 behind schedule.

Cost Performance Index (CPI) = EV / AC
CPI = $200,000 / $220,000 = 0.91
→ Since CPI < 1, the project is not cost-efficient.

Schedule Performance Index (SPI) = EV / PV
SPI = $200,000 / $50,000 = 0.8

→ Since SPI < 1, the project is behind schedule.

Conclusion: This project is both over budget and behind schedule, requiring corrective actions such as adjusting resources or revising the budget.

Importance of Earned Value Analysis in Project Management

Benefits of Using EVA
