Cash Flow = Cash Inflow - Cash Outflow
Discounted Cash Flow = CF x Discount Factor
ARR = S Cash Flow / No. of Years
ROI = (ARR / Investment) * 100 %
BCR = Benefits / Cost

PV (Present Value) = BCWS (Budgeted Cost of Work Schedule)
EV (Earned Value) = BCWP (Budgeted Cost of Work Performed)
AC (Actual Cost) = ACWP (Actual Cost of Work Performed)
CV = EV - AC
CPI = EV / AC (efficiency)
SV = EV - PV
SPI = EV / PV
ETC = BAC - EV or (BAC - EV) / CPI
EAC = AC + ETC
EAC = BAC / CPI
VAC = BAC - EAC
% COMPLETE = EV / BAC x 100
% SPENT = AC / BAC x 100
CV% = CV / EV x 100
SV% = SV / PV x 100
The following are extracted from "PMP Resources":
The PMP
exam is big on terminology. These are the basic Earned Value Terms you
need to know. If you are studying to pass the PMP exam you should know
these by heart and be able to derive them in case you are heartbroken.
They really are fairly simple. In order from first to last:
BAC = Budget at Completion (Project budget)
AC = Actual Cost of the Work Performed
EV = Earned Value
EV = Budgeted Cost of the Work Performed
EV = % complete times BAC
PV = Planned Value
PV = Budgeted Cost of the Work Scheduled
CV = Cost Variance
CV = EV - AC
CPI = Cost Performance Index
CPI = EV/AC
SV = Schedule Variance
SV = EV - PV
SPI = Schedule Performance Index
SPI = EV/PV
EAC = Estimate at Completion
EAC = BAC/CPI
ETC = Estimate to Complete
ETC = EAC - AC
VAC = Variance at Completion
VAC = BAC - EAC
