One Page Formula's for PMP Exam

1. PERT

(P + 4M + O )/ 6 Pessimistic, Most Likely, Optimistic

2. Standard Deviation

(P - O) / 6

3. Variance

[(P - O)/6 ]squared

4. Float or Slack

LS-ES and LF-EF

5. Cost Variance

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 PV

FV / (1 + r)^n

15. Internal Rate of Return

Bigger is better (IRR)

16. Benefit Cost Ratio

Bigger is better ((BCR or Benefit / Cost) revenue or payback VS. cost)

Or PV or Revenue / PV of Cost

17. Payback Period

Less is better

Net Investment / Avg. Annual cash flow.
