## eac question

Hi

I got the question that i wanted. please see the question below

SV = EV – PV

EV = SV + PV

= 30,000 + 100,000

= 130,000

CV= EV – AC

AC=EV- CV =130,000 – 50,000

= 80,000

am confused with the logic behind calculation of EV and CV. i mean when it will be plus or minus. have a look at the ev and cv calculation and their corresponding _ and + signs used in EV and CV. am bit confused. please help!

## SV=EV-PV. This relation is

SV=EV-PV. This relation is re-written to get the value of EV. Just relax and add PV to both sides of the equation. Then it becomes: SV+PV=EV or re-write: EV=SV+PV. Same thing for CV,EV, AC relation.

% Completed = 100* EV/EAC = 100* 130,000/750,000 = 17.33%

CPI = EV/AC =130,000/80,000 =1.625

If you go at this rate throughout the project, EAC = BAC/CPI = 750,000/1.625 = $461,538

## Question

How did you know to use the EAC (present CPI) formula? I was trying to use the budget rate formula AC+BAC-EV. Did you use it b/c the question asked about performance reports? I'm just curious; I want to make sure I know what to look for if I have a similar question on the exam.

Thanks for your help!

## The question does not say

The question does not say about the trend of the remaining project. So I assumed that the remaining project continues to progress at the current rate of EV, CV etc ('TYPICAL') and I used BAC/CPI formula to compute EAC. If the question clearly states that the current trend is not going to be there for the reminder (ATYPICAL) and the reminder of the project follows original plan from now on then your formula needs to be used
