Chapter 16 - Ethics and Exam Tips: PMP Formulas

This set covers essential PMP formulas from Chapter 16 including Earned Value Management, PERT distributions, and communication channel calculations.

Budget at Completion (BAC)

The original budget of the project; has no special formula.

Planned Value (PV)

$$PV = \text{Planned \% Complete} \times BAC$$

Earned Value (EV)

$$EV = \text{Actual \% Complete} \times BAC$$

Actual Cost (AC)

The total amount of money already spent on the project.

Cost Variance (CV)

$$CV = EV - AC$$

Cost Performance Index (CPI)

$CPI = \frac{EV}{AC}$; identified as one of the most popular formulas on the exam.

Schedule Variance (SV)

$$SV = EV - PV$$

Schedule Performance Index (SPI)

$SPI = \frac{EV}{PV}$; identified as one of the most popular formulas on the exam.

Estimate at Completion (EAC)

$$EAC = \frac{BAC}{CPI}$$

Estimate to Completion (ETC)

$$ETC = EAC - AC$$

Variance at Completion (VAC)

$$VAC = BAC - EAC$$

To-Complete Performance Index (TCPI)

$$TCPI = \frac{BAC - EV}{BAC - AC}$$

PERT - Beta

$$\frac{\text{Optimistic} + 4 \times \text{Realistic} + \text{Pessimistic}}{6}$$

PERT - Standard Deviation

$$\frac{\text{Pessimistic} - \text{Optimistic}}{6}$$

PERT - Triangular Distribution

$$\frac{\text{Optimistic} + \text{Realistic} + \text{Pessimistic}}{3}$$

Communications Channels

$$\frac{N(N - 1)}{2}$$
