PMP Formulas

Question	Answer
BAC - Budget At Completion	Σ(PV) at project completion
EV - Earned Value	% complete x BAC
CV - Cost Variance	EV – AC (>0 is good)
SV - Schedule Variance	EV – PV (>0 is good)
CPI - Cost Performance Index	EV / AC (>1 is good)
SPI - Schedule Performance Index	EV / PV (>1 is good)
EAC - Estimate At Completion	AC / % Complete or BAC / CPI
ETC - Estimate To Completion	EAC—AC
VAC - Variance At Completion	BAC—EAC
TCPI - To Complete Performance Index	Remaining Work / Remaining Budget (BAC—EV) / (BAC—AC) or (BAC—EV) / (EAC—AC)
AC - Actual Cost	CV / (CPI - 1)
PV - Planned Value	SV / (SPI - 1)
Qualitative Risk Score	Probability x (Iscope + Itime + Icost + Iquality)
EMV - Expected Monetary Value	Impact x Probability
Communication Channels	N (N—1) / 2 N = # of stakeholders in the project
1 Sigma = ?	68.26%
2 Sigma = ?	95.46%
3 Sigma = ?	99.73%
6 Sigma = ?	99.999%
Present Value (PV)	FV --------------- (1 + r) ^ n FV = Future Value; r = Rate of Interest n = Number of Years
PERT - Program Evaluation and Review Technique	(O+4M+P) / 6 O = Optimistic P = Pessimistic M = Most Likely
SD of Activity (sigma)	(P-O) / 6 O = Optimistic P = Pessimistic
Variance of Activity	(SD) ^ 2
Float	LS—ES = LF—EF LS = Late Start; LF = Late Finish ES = Early Start; EF = Early Finish
