Earned Value
CV = EV - AC
CPI = EV / AC
SV = EV - PV
SPI = EV / PV
EAC ‘variances will remain’ = BAC / CPI
EAC ‘fundamentally flawed’ = AC + Bottom-up ETC
EAC ‘variance will not happen again’ = AC + BAC – EV
EAC ‘over budget + deadline’ = AC + [(BAC - EV) / (CPI * SPI)]
ETC = EAC - AC
ETC ‘flawed’ = new estimate
ETC ‘unearned budget’ = BAC - EV
ETC ‘over budget + deadline’ = ETC = (BAC - EV) / (CPI * SPI)
ETC ‘variances will remain’ = (BAC / CPI) - AC
Percent Complete = EV / BAC * 100
VAC = BAC - EAC
EV = % complete * BAC
TCPI ‘based on BAC’ = (BAC – EV) / (BAC – AC)
TCPI ‘based on EAC’ = (BAC – EV) / (EAC – AC)

PERT
PERT Beta 3-point = (Pessimistic + (4 * Most Likely) + Optimistic) / 6
PERT Triangular 3-point = (Pessimistic + Most Likely + Optimistic) / 3
PERT ? = (Pessimistic - Optimistic) / 6
PERT Activity Variance = ((Pessimistic - Optimistic) / 6)^2
PERT Deviation all activities = ?sum((Pessimistic - Optimistic) / 6)^2

Communications
Communication Channels = n * (n-1) / 2

Procurement
PTA = ((Ceiling Price - Target Price) / Buyer's Share Ratio) + Target Cost

Probability
EMV = Probability * Impact in currency

Network Diagram
Activity Duration = EF - ES + 1 or Activity Duration = LF - LS + 1
Total Float = LS - ES or Total Float = LF – EF
Free Float = ES of Following - ES of Present - DUR of Present
EF = ES + duration - 1
ES = EF of predecessor + 1
LF = LS of successor - 1
LS = LF - duration + 1

Project Selection
PV = FV / (1+r)^n
FV = PV * (1+r)^n
NPV = Select biggest number. (Formula not required for exam)
ROI = Select biggest number. (Formula not required for exam)
IRR = Select biggest number. (Formula not required for exam)
Payback Period = Add up the projected cash inflow minus expenses until you reach the initial investment.
BCR = Benefit / Cost
CBR = Cost / Benefit
Opportunity Cost = The value of the project not chosen.

Depreciation
Straight-line Depreciation:
Depr. Expense = (Asset Cost – Scrap Value) / Useful Life
Depr. Rate = 100% / Useful Life
Double Declining Balance Method:
Depr. Rate = 2 * (100% / Useful Life)
Depr. Expense = Depreciation Rate * Book Value at Beginning of Year
Book Value = Book Value at beginning of year - Depreciation Expense
Sum-of-Years' Digits Method:
Sum of digits = Useful Life + (Useful Life - 1) + (Useful Life - 2) + etc.
Depr. rate = fraction of years left and sum of the digits (i.e. 4/15th)

The action of writing them down (multiple times; old fashion pencil and paper!) will help you to remember.

Hi Rami,

thanks for the compliment.
Yes, i am doing well thanks for asking. I hope you to.
Just a bit to much to do the last weeks/months, so i can't contribute here as much as i want to.
But i do have something very nice in the pipeline for projectmanagement. com. I guess it will take part and start of in the beginning of the next year ... we will see ... ;)

Markus

Praveen,

The first link opened but I could not download the guide. Maybe you can guide us through this.

As for the other two links, they opened and the pages showed error.

I agree that the act of writing them down will help you remember them, so even if you use the lists here, make your own version to help your studies.
