To complete performance index, abbreviated as SPI, represents the ratio of earned value to planned value.
To Complete Performance Index Formula |
| \( TCPI \;=\; \frac{ BAC - EV }{ BAC - AC} \) |
| Symbol |
| \( TCPI \) = to complete performance index |
| \( AC \) = actual cost |
| \( BAC \) = budget at completion |
| \( EV \) = earned value |
To Complete Performance Index Formula |
| \( TCPI \;=\; \dfrac{ BAC - EV }{ EAC - AC} \) |

| \( TCPI \) = to complete performance index |
| \( AC \) = actual cost |
| \( BAC \) = budget at completion |
| \( EAC \) = estimate at completion |
| \( EV \) = earned value |
