Julie has just completed a periodic analysis of her project. Her estimate to complete(ETC)  the project is an additional $280,000. This brings the estimated total cost (EAC) of the project to $600,000. If Julie calculates Earned Value (EV) to be $350,000, what is the cost variance (CV) on this project?

Ans is given as $30,000

CV= EV-AC

ETC=EAC-AC

Getting confused in calculating AC

If BAC = EAC*CPI i.e., BAC = EAC *EV/AC is to be considered, then is BAC = 600,000-280,000 = 320,000?
