On this page, we want to give you all the formulas needed to pass the PMP certification.

  • Number of Communication Channels = N(N−1)/2 Where N = number of stakeholders
  • Expected Monetary Value (EMV) = Probability x Impact
  • Point of total assumption (PTA) = [(Ceiling Price − Target Price)/ Buyer′s Sharing Ratio)] + Target cost
    • Target Price = Target Cost + Target Fee
  • Present value (PV) = FV/(1+r)^n Where:
    • PV = Present Value
    • FV = Future Value
    • r = Interest rate
    • n = Number of periods
  • Total Float = Late Finish (LF) – Early Finish (EF)
  • Triangular distribution: E = (O + M + P) / 3
  • Beta distribution: E = (O + 4M + P) / 6
  • Earned value formula:
    • Cost Variance (CV) = Earned Value – Actual Cost
    • Schedule variance (SV) = Earned Value – Planned Value
    • Cost Performance Index (CPI) = Earned Value / Actual Cost
    • Schedule Performance Index (SPI) = Earned Value / Planned Value
    • Estimate At Completion (EAC) =
      • Actual costo + bottom up ETC OR
      • Budget At Completion / Cost Performance Index OR
      • Actual Cost + (Budget At Completion – Earned Value) OR
      • Actual Cost + (Badget At Completion – Earned Value) / (Cost Performance Index X Schedule Performance Index)
    • To Complete Performance Index (TCPI) = (Badget At Completion – Earned Value) / (Badget At Completion – Actual Cost)
    • Estimate To Complete (ETC) = EAC – AC or reestimate.
    • Variance At Completion (VAC) = BAC – EAC
