EVM Formula Reference
Cost Variance (CV)
CV = EV - ACPositive = Under budget
Schedule Variance (SV)
SV = EV - PVPositive = Ahead of schedule
Cost Performance Index (CPI)
CPI = EV ÷ AC>1.0 = Under budget
Schedule Performance Index (SPI)
SPI = EV ÷ PV>1.0 = Ahead of schedule
Estimate at Completion (EAC)
EAC = BAC ÷ CPIProjected total cost
Variance at Completion (VAC)
VAC = BAC - EACExpected budget variance
To Complete Performance Index (TCPI)
TCPI = (BAC - EV) ÷ (BAC - AC)Required efficiency to meet BAC
Use EVM results to guide project decisions
Earned Value Management is most useful when the numbers lead to action. Compare CPI, SPI, variance, and forecast values, then decide whether to adjust scope, budget, schedule, or team capacity.
Performance Indices
CPI above 1.0 means cost efficiency is healthy; below 1.0 means the project is spending faster than earned progress.
Variances
SPI above 1.0 means schedule progress is ahead of plan; below 1.0 means the team should inspect blockers and sequencing.
Forecasts
Positive variances are healthy, while negative variances should trigger a review of budget, delivery plan, or risk response.
Track EVM follow-up work in Edworking
After calculating CPI, SPI, EAC, or TCPI, turn corrective actions into tasks, document assumptions, and review progress with your team in one workspace.
