Forecasting Future Performance Trends
   
 

The Schedule Performance and Cost Performance Indices not only monitor current project performance, they can also be used to predict future performance trends.

 
 
  • To-Complete Performance Index (TCPI) = (BAC-EV) / (BAC-AC). Indicates the CPI required throughout the remainder of the project to stay within the stated budget.

  • Estimate at Completion (EAC) = AC + ((BAC-EV)/CPI). A forecast of total costs that will be accrued by project completion based on past cost performance trends.

  • Variance at Completion (VAC) = EAC – BAC. The difference between the new Estimate at Completion and the original Budget at Completion.
