## PMP Formulas Cheat Sheet

The PMP cheat sheet is aligned with PMP PMBOK 6 and includes the PMP exam formulas that you will need to know to pass the PMP exam.

## Cost Management Formulas

 PV Planned Value EV Earned Value AC Actual Cost BAC Budget at Completion EAC Estimate at Completion Cost Variance: CV = EV – AC The amount of budget deficit or surplus + = Under planned cost0 = On planned cost– = Over plan cost
 Schedule Variance: SV = EV – PV The amount by which the project is ahead or behind the planned delivery date. + = Ahead of Schedule0 = On Schedule– = Behind Schedule
 Variance at Completion: VAC = BAC – EAC A projection of the amount of budget deficit or surplus. + = Under Planned Cost0 = On Planned Cost– = Over Planned Cost
 Cost Performance Index: CPI = EV / AC Shows the percentage of how much costs are over or under the amount of work accomplished. Greater than 1.0 = Under planned cost1.0 = On planned costLess than 1.0 = Over planned cost
 Schedule Performance Index: SPI = EV / PV A measure of schedule efficiency. Greater than 1.0 = Ahead of Schedule1.0 = On ScheduleLess than 1.0 = Behind Schedule
 Estimate at Completion: The expected total cost of completing all work expressed as the sum of the actual cost to date and estimate to complete. EAC = AC + ETC If the initial plan is no longer valid. Use new estimate. EAC = AC+BAC-EV If the future work will be accomplished at the planned rate, use the remaining budget. EAC = BAC/CPI If CPI is expected to be the same for the remainder of the project. EAC = AC+(BAC-EV)/(CPI*SPI) If both CPI and SPI influence the remaining work.
 Estimate to Complete: The expected cost to finish all remaining project work. ETC = EAC – AC Assuming the work is proceeding on plan
 To Complete Performance Index: A measure of the cost performance that must be achieved with the remaining resource in order to meet a specific management goal. TCPI = remaining work/budget available Greater than 1.0 = Harder to complete1.0 = Same to completeLess than 1.0 = Easier to complete TCPI = (BAC-EV)/(BAC-AC) The efficiency that must be maintained in order to complete on plan TCPI = (BAC-EV)/(EAC-AC) The efficiency that must be maintained in order to complete the current EAC.

## Schedule Management Formulas

 PERT Weighted Average = (O+4M+P)/6 PERT Standard Deviation = (P-O)/6 Project Evaluation & Review Technique for estimating activity duration.O=optimistic, M=Most likely, P=Pessimistic
 Float (or slack) = LS – ESFloat (or slack) = LF – EF LS = Late StartES = Early StartLF = Late FinishEF = Early Finish

## Communication Management Formulas

 Communication Channels = N(N-1)/2
