ACWP/AC = The actual cost of work performed to date or for a given time period.
BCWS/PV = Known in advance; Budgeted cost of work scheduled during a given time period.
BCWP/EV = How much work got done.
EAC = Estimate at completion is the expected cost of work when completed.
ETC = Estimate to complete is the additional budget or costs needed to complete the activity or project if everything continues at current levels of performance.
BAC = Budget at completion is the remaining budget less the work that's been done to date.
CV = EV - AC
SV = EV - PV
CPI = EV / AC
SPI = EV / PV
EAC = AC + ETC
- Use when past assumptions are incorrect
EAC = (AC + BAC) - EV
- Use when variances are not typical or are not expected to continue
EAC = AC + ((BAC - EV)/CPI)
- Use when variances are expected to remain the same
ETC = EAC - AC
VAC = BAC - EAC

(n*(n-1))/2
Formulas - Project Selection
FV = PV*((1 + i) ^ n); i = interest rate; n = number of periods
NPV = (Summartion of the PV of future project cash inflows) - (Project Investment). When only considering the monetary aspect, the highest NPV wins.
NPV assumes cash inflows are reinvested at the cost of capital rate.
IRR is the discount rate when NPV is zero.
Project with a higher IRR are generally considered better.
Formulas - Expected Monetary Value
EMV = The average or expected monetary outcome of a decision if it can be repeated many times. This is determined by multiplying the monetary outcomes by their respective probabilities. The results are then added to arrive at the EMV.
