Answer:
Planned value= $ 450,000
Earned Value (EV) = $ 300,000
Actual Cost = $ $500,000
Cost Variance (CV) = EV – AV = -20,000
Schedule Variance (SV) = EV – PV = -15,000
Cost Performance Index (CPI) = EV/AV = 0.6 = 60 %
Schedule Performance Index (SPI) = EV/PV = 0.66 = 66 %
Estimate at Completion (EAC) = PV/CPI = 750,000
Estimated Time to Complete = Original Time Estimate/SPI
Hope it Helps :)
