Example
• WBS item : build a wall
– Planned scope : 25 bricks
– Planned time : 5 days
– Planned cost : 500 € (m*d
= 100 €) (1 brick = 20 €)
• Today = end of day 3
– Actual scope : 13 bricks
– Spent time : 3 days
– Spent cost : 280 €

FORMULA VALUE
Planned Value (PV)
Actual Cost (AC)
Earned Value (EV)
Budget at completion (BAC)
Cost Variance (CV) CV = EV – AC
Schedule Variance (SV) SV = EV – PV
Cost Performance Index (CPI) CPI = EV / AC
Schedule Performance Index (SPI) SPI = EV / PV
Estimate at completion (EAC) Basic : EAC = AC + (BAC – EV)
Considering CPI : EAC = BAC / CPI
Considering CPI & SPI (on time) :
EAC = AC + [( BAC – EV ) / (CPI *
SPI)]
Estimate to complete (ETC) Basic
Considering CPI
Considering CPI & SPI
