fin.earned-value-management Calculator
Calculates schedule variance, cost variance, and performance indices from EVM baseline data. The EAC formula EAC = AC + (BAC − EV) / CPI is the most commonly used — it assumes future performance matches historical CPI.
Inputs
Bac Total
Reference formula or conversion factor shown for context.
Pv Planned Value
Reference formula or conversion factor shown for context.
Ev Earned Value
Reference formula or conversion factor shown for context.
Ac Actual Cost
Reference formula or conversion factor shown for context.
Results
schedule variance SV ($)
Standard deviation squared — average squared deviation from the mean. Essential for ANOVA, regression, and many statistical tests, though the squared units make it less intuitive directly.
cost variance CV ($)
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 performance index SPI
A normalised score comparing the result to a reference baseline.
cost performance index CPI
A normalised score comparing the result to a reference baseline.
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.
