ID Concept Formula Comments As of today, what is the estimated value for the work planned to be PV Present Value done. As of today, what is the value of EV Earned Value the work done. As of today, what is the cost incurred for the work AC Actual Cost accomplished. How much is the budget to BAC Budget at Completion complete the project. CV Cost Variance CV = EV - AC SV Schedule Variance SV = EV - PV CPI Cost Performance Index CPI = EV / AC SPI Schedule Performance Index SPI = EV / PV As of today, how much do we expect the total project EAC Estimate at Completion EAC = BAC / CPI cost will be. EAC = AC + (BAC - EV) Reestimate the remaining work less work to be ETC Estimate to Complete ETC = EAC - AC done
