2. Standard Deviation (P - O) / 6
3. Variance [(P - O)/6 ]squared
4. Float or Slack LS-ES and LF-EF
5. Cost Variance EV - AC
6. Schedule Variance EV - PV
7. Cost Perf. Index EV / AC
8. Sched. Perf. Index EV / PV
9. Est. At Completion (EAC) BAC / CPI,
AC + ETC -- Initial Estimates are flawed
AC + BAC - EV -- Future variance are Atypical
AC + (BAC - EV) / CPI -- Future Variance would
be typical
10. Est. To Complete
Percentage complete
EAC - AC
EV/ BAC
11. Var. At Completion BAC - EAC
12. To Complete Performance
Index TCPI
Values for the TCPI index of less then 1.0 is good
because it indicates the efficiency to complete is
less than planned. How efficient must the project
team be to complete the remaining work with the
remaining money?
( BAC - EV ) / ( BAC - AC )
13. Net Present Value Bigger is better (NPV)

#14 Present Value formula is incorrect.
Submitted by slangley on Mon, 03/31/2008 - 02:04.
As written the formula only works for 1 year.
The proper formula should be:
PV= FV / ((1 + r)^term)

How I remember EV formula
Submitted by Have2passfirsttry on Fri, 07/08/2011 - 00:59.
I learned this in a class I took.I thought I would share.
AC operand EV operand PV
--------------- --------------
CV= _ _ SV
CPI= / / SPI
Arranged alphabetically AC, EV, PV, and the sides Cs before Ss
Begin with EV and move to the right or left to find your sides
CV= EV-AC
SV=EV-PV
CPI=EV/AC
SPI=EV/PV
Then u just have to remember/memorize :
EAC=BAC/CPI

Formulas / Math for PMP
Submitted by buffele001 on Wed, 05/30/2012 - 00:50.
If a problem can have more than one way of being solved, write down all the ways. This is
because most math problems have an easy way and a hard way to solve, and the easy way
may be a different method each time.-Arthur van der Vant
