What is Earned Value Management?
Earned Value Management (EVM) is a project management technique that combines scope, schedule, and cost data to measure project performance and progress objectively.
Key formulas
- Cost Variance (CV) = EV − AC
- Schedule Variance (SV) = EV − PV
- Cost Performance Index (CPI) = EV / AC
- Schedule Performance Index (SPI) = EV / PV
A CPI or SPI above 1.0 indicates the project is performing better than planned on cost or schedule respectively; below 1.0 indicates it is behind or over budget.
This tool is for general project-planning education.
