Estimate at Completion

Estimate at completion, abbreviated as EAC, is the sum of the actual cost to date and the estimated sum to complete the project.

 

Estimate at Completion Formula

\(\large{ EAC =  AC + \left(BAC - EV\right)  }\)

Symbol

\(\large{ EAC }\) = estimate at completion

\(\large{ AC }\) = actual cost

\(\large{ BAC }\) = budget at completion

\(\large{ EV }\) = earned value

 

Estimate at Completion Formula

\(\large{ EAC =  \frac{ BAC }{ CPI }  }\)

Symbol

\(\large{ EAC }\) = estimate at completion

\(\large{ BAC }\) = budget at completion

\(\large{ CPI }\) = cost performance index

 

Estimate at Completion Formula

\(\large{ EAC =  AC + \frac{ BAC \;-\; EV }{ CPI \; SPI }  }\)

Symbol

\(\large{ EAC }\) = estimate at completion

\(\large{ AC }\) = actual cost

\(\large{ BAC }\) = budget at completion

\(\large{ CPI }\) = cost performance index

\(\large{ EV }\) = earned value

\(\large{ SPI }\) = schedule performance index
