To Complete Performance Index

 

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, abbreviated as SPI, represents the ratio of earned value to planned value.
