finding EV, when CPI and AC are given.

Submitted by rjmorris on Thu, 04/25/2013 - 19:09

Hi All,

I have a rather basic question that I hope someone can help me out with. 

What is the Algebraic rule for finding the "unknown" value in a question.  For Instance, 

The question gives both the CPI and AC and asks for EV.   Would that be AC x CPI ?  For some reason,

this is eluding my Brain today.   Also;  Given is CV and AC, find EV.      is that CV/AC ?

I know its basic math,  Just not sure about the routines,

Thanks to all in Advance!

Robert

Refer below mentioned formulas:-



  • CPI (Cost Performance Index)=EV/AC

  • CV (Cost Variance) = EV - AC

So, your first point is correct...EV=CPI x AC


However, there is a correction in your second point.....EV= CV + AC
