If actual cost (AC) = 500, planned value (PV) = 600, earned value (EV) = 700 what is cost variance (CV)?

200

CV = EV-AC

200 of course

CV = EV - AC

CV =700 -500 =200

CV200

Vow, everyone is right on the money.

The answer

CV = EV - AC

200 =700 -500

I Agreed Mr.Alex Al Yazouri  

CV = EV - AC =700 -500 =200

SV = EV - PV =700 -600 =100

So the project is under budget and a head of schedule

see above, only need to know that CV = EV-AC

 cost variance =  earned value  -  actual cost

        CV            =          EV           -        AC 

        200           =         700          -        500             

CV = EV - AV    (700-500=200)

Cost Variance =200 

I agree... if the actual cost is500 and the earned value is700 the difference/cost variance is 200
