ETC = BAC EVAssumes future work to beperformed as budgeted
ETC (for atypical variance)Estimate To Complete
FormulaDescriptionAbbreviationVariable
ETC = (BAC EV) / CPI
or ETC = EAC AC
Assumes past performance to
continue throughout
ETC (for typical variance)
TCPI = (BAC EV) / (BAC AC)
BASED ON BAC
or TCPI = (BAC EV) / (EAC AC
BASED ON NEW EAC
Cost performance necessary toachieve BAC ornew EAC goal
Work remaining divided by fundsremaining
TCPITo-Complete Performance Index
VAC = BAC EACForecast of varianceVACVariance At Completion
EAC = AC + ETC =AC+(BACEV)/C
or EAC = BAC / CPI
Assumes past performance tocontinue throughout
EAC (for typical variance)
EAC = AC + BAC EVAssumes future work to beperformed as budgeted
EAC (for atypical variance)
EAC = AC + Bottom-up ETCUse when original est. is flawedEACEstimate At Completion
