fin.earned-value-CPI-SPI Calculator
Calculates CPI and SPI from project EVM data and estimates cost and schedule at completion. CPI and SPI that are both below 1.0 early in a project are a strong predictor of final outcome — early EVM data has significant predictive value.
Inputs
Bac Usd
Reference formula or conversion factor shown for context.
Pv Usd
Reference formula or conversion factor shown for context.
Ev Usd
Reference formula or conversion factor shown for context.
Ac Usd
Reference formula or conversion factor shown for context.
Results
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.
cost variance CV ($)
Standard deviation squared — average squared deviation from the mean. Essential for ANOVA, regression, and many statistical tests, though the squared units make it less intuitive directly.
estimate at completion EAC ($)
The value at the specified point or condition.
variance at completion VAC ($)
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.
project health
Overall health score or status — a composite measure of how well the system, asset, or metric is performing.
