The burn rate is the inverse of the CPI (i.e., 1/CPI). Or you can calculate it is AC/EV.

So are we to use burn rate = 1/CPI or it is CPI itself?

Hi Cornelius,

I am really excited, and can't wait to attend the Exam.

So, for now, I only need to know that CPI = EV / AC, regardless of how it is explained in term of ratio, becuase I got a little confused about how it was described in terms of ratio between page 2 and 8.

I didn't find any reference to Burn Rate in the PM Promula Guide which I purchased some time ago.

It was mentioned that Burn Rate is the reverse of CPI. Could you please update the formula guide to include such terms.

Also, after reading the Formula Study Guide PDF, in page 2 it mentiones that CPI is EV / AC, then in page 8 it is AC / EV.
