Earned value calculator
Enter four figures at the same status date to get the standard earned value measures. The values loaded below are an invented example, not real project data.

How these are calculated
| Measure | Formula |
|---|---|
| Cost variance | EV − AC |
| Schedule variance | EV − PV |
| CPI | EV ÷ AC |
| SPI | EV ÷ PV |
| EAC (CPI method) | BAC ÷ CPI |
| EAC (CPI × SPI method) | AC + (BAC − EV) ÷ (CPI × SPI) |
| ETC | EAC − AC |
| VAC | BAC − EAC |
| TCPI (to BAC) | (BAC − EV) ÷ (BAC − AC) |
| Percent complete | EV ÷ BAC |
SPI is cost-based, so it drifts towards 1.0 as a project finishes, however late it is. Late in a project, look at time-based schedule measures as well. These formulas are standard, but check them against the method your organisation or contract specifies.
The status colours use simple bands: an index of 1.0 or better is on track, 0.95 to 1.0 is worth watching, below 0.95 needs attention. Your organisation's thresholds may differ.
