4. Earned Value Problem Solution Term Calculation Value Interpretation of the Answer PV 500+500+500 $1500 By third day, we should have done $1500 worth of Work. EV Complete, Complete, half done 500+500+250=$1250 $1250 We have actually accomplished only work worth $1250 AC 500 plus 700 plus 300=$1500 $1500 We have actually spent $1500 CV $1250 minus $1500 -$250 We are over budget by $250 SV $1250 minus $1500 -$250 We are behind Schedule CPI $1250 divided by $1500 .83 We are getting 83 cent out of every dollor spent SPI $1250 divided by $ 1500 .83 We are progressing at 83% of the rate originally planned.
