33 PMP formulas and calculations
PV = BAC × (Planned % Complete)
EV = BAC × (Actual % Complete)
AC = Total actual cost incurred
CV = EV − AC
SV = EV − PV
CPI = EV ÷ AC
SPI = EV ÷ PV
EAC = BAC ÷ CPI
EAC = AC + ETC
EAC = AC + (BAC − EV)
EAC = AC + [(BAC − EV) ÷ (CPI × SPI)]
ETC = EAC − AC
VAC = BAC − EAC
TCPI = (BAC − EV) ÷ (BAC − AC)
TCPI = (BAC − EV) ÷ (EAC − AC)
PERT = (O + 4M + P) ÷ 6
σ = (P − O) ÷ 6
σ² = [(P − O) ÷ 6]²
TF = LS − ES = LF − EF
FF = ES(successor) − EF(current)
ES = max(EF of all predecessors)
EF = ES + Duration − 1
LS = LF − Duration + 1
LF = min(LS of all successors)
N(N−1) ÷ 2
EMV = Probability × Impact
Risk Score = Probability × Impact
PTA = [(Ceiling Price − Target Price) ÷ Buyer's Share Ratio] + Target Cost
Velocity = Story Points Completed ÷ Sprint
Remaining Sprints = Remaining Story Points ÷ Velocity
Cycle Time = Completion Date − Start Date
Lead Time = Completion Date − Request Date
Throughput = Items Completed ÷ Time Period
