## Cost Management

Planned Value PVFV/(1+i)^n
Cost Variance CVEV - AC; (-)=overbudget (+)=within budget
Schedule Variance SVEV - PV; (-) = behind schedule, (+) = on schedule
Cost Performance Index CPIEV/AC; <1 over budget, >1=under budget
Schedule Performance Index SPIEV/PV; <1 behind, >1 ahead, =1 on schedule

## Earned Value Management

Estimate At Completion (variances ATYPICAL) EACAC + (BAC - EV)
Estimate At Completion (TYPICAL) (assume same rate of spending to continue)
EAC=
BAC/CPI
Estimate At Completion (Bottom Up) (most accurate, time consuming)AC + ETC
Estimate At Completion (Hard Date/Worst/Continue)
(Assume current cost/sched. perf. to continue - what will it cost me to make this date)
AC + [(BAC-EV)/(CPI * SPI)]
Estimate To Completion (Expected cost of work remaining) ETCEAC - AC
Variance At Completion
(-) Over Budget, (+) Under Budget
VAC=
BAC - EAC
To Complete Performance Index (Original Budget Attainable)(Cost Performance rate needed to complete within budget)
TCPI
(BAC-EV)/(BAC-AC)
To Complete Performance Index (Original Budget NOT Attainable) (Assumes original budget cannot be achieved)TCPI(BAC - EV)/(EAC-AC)
