## BURN RATE=1/CPICPI = EV/AC=>

BURN RATE=1/CPI

CPI = EV/AC

=> Burn rate = AC/EV = 900,000/750,000 = 1.2

## Burn rate vs EVM

Perhaps part of your question has to do with understanding the relationship between burn rate and Earned Value Management. PMI has an article on this topic. It's free if you are a member. Please see http://marketplace.pmi.org/Pages/ProductDetail.aspx?GMProduct=00100294501 for more information.

## EVM

CPI is 1 so if they are asking about Burn Rate not sure this is the answer.

## CPI is not 1

CPI is not 1

when CPI is

EV/AC

than this is here

750.000/900.000

equals 0.83

when burn rate is 1/CPI=0,83

then burn rate is 1.2

what i wanna know:

could anybody explain where we need to know this burn rate for and what tells it difference in comparison to the CPI.

Like i udnerstand tna tells a burn rate higher than 1, that the project "eats" budget faster than it should and we would end up over budget, right?

But that is the same what CPI less than 1 tells us, isn't it?

I do not really get the point.

Any thoughts?

btw: Since this "burn rate" is wether mentioned in the PMBok Guide neither not in any of the Prep Book Guides i know so far, i assume we do not really need to know about, do we?
