## pmp formulas

### Here is list for pmp formulas.

 PERT = (P+4M+O)/6 P = Pessimistic M= Most Likely O= Optimistic Standard deviation = (P-O)/6 Variance = {(P-O)}/6 Project PERT = Sum of PERT value of each task Project Variance = Sum of variance of each task Normal distribution (sigma) 6 sigma = 99.99% 3 sigma = 99.73% 2 sigma = 95.46% 1 sigma = 68.26% No of communication channel = N*(N-1)/2 Here N is number of member in project team If team have 10 member then =10 *(10-1)/2 =>10*9/2=>45 Communication channel Float = LF – EF = LS- ES LF = Late finish EF = Early finish LS = Late start ES = Early start Float value is 0(zero) on critical path. Schedule variance (SV) = EV-PV     (Positive variance is good) EV = Earned value     PV=Planned value Cost Variance (CV) = EV- AC    (Positive variance is good EV = Earned value     AC= Actual cost Cost performance index (CPI) = EV/AC (>1 are good) Schedule performance index (SPI) = EV/PV (>1 are good) Estimate at complication  (EAC) = 1.       Estimating assumptions are not  valid = AC+ETC 2.       Current variance are atypical = AC+BAC-EV 3.       Current variance are Typical =AC+(BAC-EV)/CPI 4.       Variance to continue at current rate = BAC/CPI 5.       EAC = AC + [(BAC -EV)/(CPI*SPI)] Estimate to complete (ETC)  = EAC-AC Variance at complete (VAC) = BAC-EAC TCPI = 1.       TO Complete performance index based on BAC= (BAC-EV)/(BAC-AC) 2.       To complete performance index based on EAC= (BAC-EV)/(EAC-AC) Percentage complete of budget=(EV/BAC)* 100 Benefit Cost Ratio (BCR) = Payback/project cost Bigger is better Net present value (NPV) bigger is better Internal Rate of Return (IRR) bigger is better Present Value PV=  FV / ((1 + r)^term) Expected Monetary Value = Probability * Impact Procurement related Actual cost (AF) ={(TC-AC)*SSR}+TF TC = target cost AC = actual cost SSR= Sellers share ration TF= target fee
