TCPI stands for the "To Complete Performance Index", CPI stands for "Cost Performance Index".

TCPI = (Budget - EV [Earned Value])/ (EAC [Estimate At Complete] - AC[Actual Cost])

CPI = EV/ AC

A TCPI higher than a CPI means that the performance of the project is improving, a TCPI equal to the CPI means that the performance of the project is still the same, a TCPI lower than the CPI means that the performance of the project is deteriorating.
