Below is a list of main EVM equations.

Variances
CV Cost Variance = BCWP – ACWP
= EV – AC
= (CV /BCWP) *100
CV% Cost Variance % = (EV – AC) / EV
= (BCWP – ACWP) / BCWP
SV Schedule Variance = BCWP–BCWS
= EV – PV
= (SV /BCWS) *100
SV% Schedule Variance % = (EV – PV) / PV
= (BCWP – BCWS) / BCWS
VAR Variance at Completion = BAC – EAC
Overall Status
% Scheduled = PVcum / BAC
= BCWScum / BAC
% Complete = EVcum / BAC
= BCWPcum / BAC
% Budget Spent = ACcum / BAC
= ACWPcum / BAC
WR Work Remaining = BAC – EVcum
= BAC – BCWPcum
Performance Index
CPI Cost Performance Index = EV / AC
= BCWP / ACWP
SPI Schedule Performance Index = EV / PV
= BCWP / BCWS
TCPIBAC To Complete Performance Index = WR / (BAC – ACWPcum)
(Total Budget – EV ) / (Total Budget – AC)
TCPIEAC To Complete Performance Index = WR / (EAC – ACWPcum)
= (Total Budget – BCWP ) / ( Total Budget – ACWP)
= (BAC – BCWPCUM) / (EAC – ACWPCUM)
Estimate at Completion
EAC Estimate at Completion = BAC / CPIcum
= ACWP + ETC
= ACWP + (BAC – BCWP) / (CPI x SPI)
EACCPI Estimate at Completion – Critical Performance Index = ACcum + WR / CPIcum
EACComposite Estimate at Completion –
Composite
= ACcum + WR / (CPIcum ∙ SPIcum)
Critical Path Length Index
CPLI Critical Path Length Index = (CP Length(Time Now To Contract End)) + Total Float (To Contract End Baseline Finish)) /CP Length
Baseline Execution Index
BEI Baseline Execution Index = Tasks with Actual Finish Date / (# of Baseline Tasks Scheduled to Finish Prior to Status Date +Tasks Missing Baseline Start or Finish Date)
DoD TRIPWIRE METRICS
CPI Cost Efficiency = BCWP / ACWP; Favorable is > 1.0, Unfavorable is < 1.0
SPI Schedule Efficiency = BCWP / BCWS; Favorable is > 1.0, Unfavorable is < 1.0
