In the world of project management, success isn’t just about meeting deadlines. It’s about staying within budget, managing time effectively, and ensuring project objectives are met. This is where Earned Value Management (EVM) becomes a crucial component, offering a quantitative method for tracking project performance. Our Earned Value Calculator is a powerful, user-friendly tool that helps project managers, planners, and team leads monitor the financial and schedule efficiency of their projects in real-time.
Whether you’re working on construction, IT, product development, or any other project-based environment, understanding earned value metrics can empower better decision-making and timely course corrections. This tool simplifies complex calculations, turning inputs into insightful performance indicators.
What Is the Earned Value Calculator?
The Earned Value Calculator is a free, online tool designed to compute key project performance metrics using Earned Value Management principles. It allows users to input key project figures and instantly receive critical results like:
- Cost Performance Index (CPI)
- Schedule Performance Index (SPI)
- Cost Variance (CV)
- Schedule Variance (SV)
- Estimate at Completion (EAC)
- Variance at Completion (VAC)
These metrics provide a comprehensive view of how a project is performing relative to its budget and schedule, highlighting whether you’re under budget, over budget, ahead of schedule, or falling behind.
How to Use the Earned Value Calculator
Using the calculator is straightforward. Here’s a step-by-step guide:
Step 1: Enter the Required Inputs
You’ll need the following five values:
- Planned Value (PV): The approved budget for the work scheduled to be completed by a certain date.
- Earned Value (EV): The budgeted cost of the work that has actually been completed by the same date.
- Actual Cost (AC): The actual cost incurred for the work performed.
- Budget at Completion (BAC): The total planned budget for the entire project.
- Estimate to Complete (ETC): The estimated cost required to complete the remaining project work.
Step 2: Click the Calculate Button
Once the inputs are filled in, click the “Calculate” button to generate your results.
Step 3: Review the Results
The calculator will instantly show:
- Cost Performance Index (CPI)
- Schedule Performance Index (SPI)
- Cost Variance (CV)
- Schedule Variance (SV)
- Estimate at Completion (EAC)
- Variance at Completion (VAC)
These values help you assess the current and future state of your project.
Earned Value Management Formulas Used
The calculator uses standard Earned Value formulas:
- Cost Performance Index (CPI) = Earned Value / Actual Cost
Formula: EV ÷ AC
Interprets cost efficiency. A CPI > 1 means you’re under budget. - Schedule Performance Index (SPI) = Earned Value / Planned Value
Formula: EV ÷ PV
Interprets schedule efficiency. An SPI > 1 means you’re ahead of schedule. - Cost Variance (CV) = Earned Value – Actual Cost
Formula: EV – AC
Positive CV indicates a project is under budget. - Schedule Variance (SV) = Earned Value – Planned Value
Formula: EV – PV
Positive SV indicates a project is ahead of schedule. - Estimate at Completion (EAC) = Actual Cost + Estimate to Complete
Formula: AC + ETC
Forecast of total cost at project completion. - Variance at Completion (VAC) = Budget at Completion – Estimate at Completion
Formula: BAC – EAC
Indicates projected budget surplus or deficit at project completion.
Example Calculation
Let’s go through a practical example:
- Planned Value (PV): $50,000
- Earned Value (EV): $45,000
- Actual Cost (AC): $55,000
- Budget at Completion (BAC): $100,000
- Estimate to Complete (ETC): $40,000
Using the formulas:
- CPI = 45,000 ÷ 55,000 = 0.818
- SPI = 45,000 ÷ 50,000 = 0.9
- CV = 45,000 – 55,000 = -10,000
- SV = 45,000 – 50,000 = -5,000
- EAC = 55,000 + 40,000 = 95,000
- VAC = 100,000 – 95,000 = 5,000
Interpretation:
- The project is over budget and behind schedule.
- However, the forecast indicates it may still finish within the total budget.

20 Frequently Asked Questions (FAQs)
1. What is Earned Value Management (EVM)?
It is a project management technique that integrates scope, cost, and schedule to assess performance and progress.
2. What is the Earned Value Calculator used for?
To calculate key project metrics like CPI, SPI, CV, SV, EAC, and VAC.
3. How accurate is the calculator?
It uses industry-standard formulas for accurate and reliable results.
4. Can I use this tool for any type of project?
Yes, it works for construction, IT, research, marketing, and more.
5. What does CPI tell me?
It shows cost efficiency. A CPI < 1 indicates cost overruns.
6. What does SPI tell me?
It shows schedule efficiency. An SPI < 1 indicates the project is behind schedule.

EV is what you’ve actually achieved; PV is what you planned to achieve.
8. Why is my CV negative?
A negative cost variance means you’ve spent more than you earned—over budget.
