Introduction
Earned Value Management (EVM) is a project management technique that evaluates project performance by combining measurements of scope, schedule, and cost in a singular integrated system. Learning how to calculate earned value management effectively helps project managers to assess the project's progress quantitatively, predict future performance, and identify any deviations from the plan. This technique provides essential insights that aid in maintaining control over the project, ensuring timely and on-budget delivery.
Through this guide, we will explore the foundational elements of earned value management including key components like Planned Value (PV), Earned Value (EV), and Actual Cost (AC). Each of these elements plays a crucial role in calculating and analyzing the efficiency and effectiveness of project management. Understanding these metrics is critical for anyone looking to enhance project assessment and outcome predictability.

How to Calculate Earned Value Management
Understanding Earned Value
Earned Value (EV) is a pivotal metric in project management that helps track a project’s progress against its schedule and budget. It is calculated using the formula EV = Percent of Completed Work × Budget at Completion (BAC).
Calculating Key Components
First, determine the Budget at Completion (BAC), which is the total project budget. Next, quantify and determine the percentage of completed work by analyzing the project's progression.
Additional Metrics for Project Health
Beyond EV, other valuable metrics include Planned Value (PV), which is based on the planned progression of the project (PV = % of Completion Based on Plan), and Actual Cost (AC), the real cost incurred (AC = ACWP).
Schedule Variance (SV) and Cost Variance (CV) are derived as SV = EV - PV and CV = EV - AC, respectively, indicating timeline adherence and budget management.
Performance Indices and Forecasting
To assess efficiency, use the Cost Performance Index (CPI) and Schedule Performance Index (SPI), calculated as CPI = EV / AC and SPI = EV / PV. Forecast future project cost and performance with Estimate At Completion (EAC) and Estimate To Completion (ETC), using formulas EAC = BAC / CPI and various ETC calculations for different scenario analyses.
Utilizing Tools for EVM
For accuracy and efficiency, utilize EVM software tools such as Microsoft Project, EcoSys, or Oracle Primavera. These tools facilitate seamless calculation and real-time project tracking.
By understanding and applying these calculations and tools, practitioners can maintain control over project budgets and schedules, ensuring successful project delivery.
How to Calculate Earned Value Management
Understanding Earned Value
Earned Value Management (EVM) provides a method for measuring project performance. It integrates project scope, time, and cost measures to help you understand project progress and efficiency at a glance. Essentially, to determine the earned value (EV), multiply the percent of completed work by the Budget at Completion (BAC). Use the formula: EV = \% \text{ of completed work} \times BAC.
Steps to Calculate Earned Value
Begin by quantifying the work completed to date. Analyze project activities to determine what percentage of the project has been completed. This percentage, once established, is used alongside the total project budget to find the EV using the formula: EV = \% \text{ of completed work} \times BAC.
Applying Earned Value Formulas
Once you have calculated EV, it can be used to assess other crucial project metrics such as:
- Cost Variance (CV) using CV = EV - AC
- Schedule Variance (SV) using SV = EV - PV
- Cost Performance Index (CPI) using CPI = EV / AC
- Schedule Performance Index (SPI) using SPI = EV / PV
Using EVM to Enhance Project Tracking
EVM enables project managers to scrutinize the cost efficiency and time effectiveness of any project. By using the EV formula in conjunction with other EVM metrics, stakeholders can identify potential project risks early, adjust schedules, and optimize resource allocation to ensure project success.

Examples of Calculating Earned Value Management
Example 1: Basic EVM Calculation
Start by determining the Planned Value (PV), which is the budget assigned to the scheduled work. If a project budget is $100,000 and 50% of the project should be completed, the PV is $50,000. Next, ascertain the Actual Cost (AC), the total expenses incurred. If the expenses are $40,000, that's the AC. The Earned Value (EV) is the actual value of work done, which at 40% completion would be $40,000. The Cost Performance Index (CPI) and Schedule Performance Index (SPI) are calculated as follows: CPI = EV / AC, SPI = EV / PV.
Example 2: Project Over-budget
With a PV of $60,000 and an AC of $80,000 for a project 70% complete, EV would be $70,000. The CPI, indicating cost efficiency, is 0.875, showing over-spending. The SPI is 1.17, reflecting a better-than-planned schedule performance.
Example 3: Delayed Project Analysis
Consider a delayed project with PV of $30,000, but only $15,000 worth of work completed (EV). If the AC is also $15,000, the CPI would be 1.00 (on budget), but the SPI of 0.50 indicates severe schedule delays.
Example 4: Perfect Scenario
For a perfectly on-schedule and on-budget project, if PV and EV are both $50,000 with an AC of $50,000, both CPI and SPI would be 1.00, indicating optimal project performance.
Example 5: Comprehensive Example
In a comprehensive EVM example, consider a project with a total budget of $200,000. At a 60% completion review, the planned budget (PV) is $120,000, the actual spend (AC) is $140,000, and the EV is $100,000. This translates to a CPI of 0.71 and an SPI of 0.83, indicating both cost overruns and schedule delays.
