Earned Value Analysis Calculator
Calculate project performance metrics including CPI, SPI, and ETC using earned value methodology
About this calculator
The Earned Value Analysis Calculator is a powerful project management tool that measures project performance by comparing planned work, actual work completed, and costs incurred. It calculates key performance indicators including Cost Performance Index (CPI), Schedule Performance Index (SPI), and Estimate to Complete (ETC). This methodology helps project managers identify cost overruns, schedule delays, and forecast final project outcomes early, enabling proactive decision-making and corrective actions to keep projects on track and within budget.
How to use
Enter your project's Planned Value (PV), Earned Value (EV), and Actual Cost (AC) into the calculator. The tool will automatically compute performance metrics including CPI, SPI, Cost Variance, Schedule Variance, and projected completion estimates. Review the results to assess whether your project is ahead or behind schedule and over or under budget.
Frequently asked questions
What does a CPI below 1.0 indicate?
A Cost Performance Index below 1.0 means your project is over budget, spending more than planned for the work completed.
How is Schedule Performance Index calculated?
SPI is calculated by dividing Earned Value by Planned Value (SPI = EV/PV), measuring schedule efficiency against the baseline.
What is Estimate to Complete used for?
ETC forecasts the remaining cost needed to finish the project based on current performance trends and efficiency rates.
