fin.project-earned-value Calculator
Calculates Earned Value Management (EVM) metrics — CPI, SPI, EAC, and ETC — from budget, planned value, and earned value. CPI below 1.0 means the project is spending more than budgeted for work completed — the final cost at completion can be estimated as BAC / CPI.
Inputs
Budget At Completion
Reference formula or conversion factor shown for context.
Planned Value Pct
Reference formula or conversion factor shown for context.
Earned Value Pct
Reference formula or conversion factor shown for context.
Actual Cost
Reference formula or conversion factor shown for context.
Results
cost variance CV ($)
Standard deviation squared — average squared deviation from the mean. Essential for ANOVA, regression, and many statistical tests, though the squared units make it less intuitive directly.
schedule variance SV ($)
Standard deviation squared — average squared deviation from the mean. Essential for ANOVA, regression, and many statistical tests, though the squared units make it less intuitive directly.
cost performance index CPI
A normalised score comparing the result to a reference baseline.
schedule performance index SPI
A normalised score comparing the result to a reference baseline.
estimate at completion EAC ($)
The value at the specified point or condition.
status
Current state of the system, process, or metric — typically pass/fail, healthy/warning/critical, or a descriptive classification.
