COST VARIANCE - CV

Cost variance is what you expected to spend versus what you actually spent.

 

CV = EV - AC

SHEDULE VARIANCE - SV

 

 

SV = EV - PV

COST PERFORMANCE INDEX - CPI

CPI = EV / AC

SCHEDULE PERFORMANCE INDEX - SPI

SPI = EV / PV

ESTIMATE AT COMPLETION - EAC

Using most accurate method:

EAC = Bottom Up ETC

Assuming variances are typical

EAC = BAC / CPI

Assuming variances are atypical

EAC = AC + (BAC + EV)

Assuming variances are poor cost & Firm end date

AC +(BAC - EV) / (CPI X SPI)

 

ESTIMATE TO COMPLETE - ETC

ETC = EAC - AC

VARIANCE AT COMPLETION - VAC

VAC = BAC - EAC

PRESENT VALUE - PV

PV = FV  / (1 + I)pot n 

EXPECTED ACTIVITY DURATION / COST (BETA / PERT)

(O + M + P) / 3
