Earned Value Techniques:
BAC(Budget At Completion)

PV(Planned Value)
PV = BAC * (Planned/Complete) ----as per schedule

EV(Earned Value), measures how much work that is been done
EV = BAC * (Actual/Complete)

SPI(Schedule Performance Index)
SPI = EV/PV if SPI>1, ahead of schedule; otherwise, behind schedule.

SV(Schedule Variance)
SV = EV - PV

Actual Cost(how much you've spend)

CPI(Cost Performance Index) ---whether you're over or under budget, or within budget or not
CPI = EV / AC

CV(Cost Variance) --- how much above or below your budget you are
CV = EV - AC

EAC(Estimate At Completion) ---predict the total cost of the project
EAC = BAC/CPI

ETC(Estimate to Complete) --- how much more money you'll need
ETC = EAC - AC

VAC(Variance at Completion) --- predicts the variance when the project is done
VAC = BAC - EAC page380
