Assume that you have completed three months of the project. The BAC was $120,000 for this six-month project. You can also make the following assumptions:
PV = $60,000
EV = $55,000
AC = $50,000
What is the cost variance, schedule variance, cost performance index (CPI), and schedule performance index (SPI) for the project?

Explanation:

PV = $60,000

EV = $55,000

AC = $50,000

Cost variance = EV-AC

                       =$55,000 - $50,000

                       = $5,000

Schedule variance = EV-PV

                               =$55,000-$60,000

                               = - $5,000

Cost Performance Index= EV/AC

                                        =$55,000/$50,000

                                        =1.1% or 0.011

Schedule Performance Index= EV/PV

                                                =$55,000/$60,000

                                                =0.91% or 0.0091

i mean they dont have to
