PMP Formula: To-complete Cost Performance Index

PMP Formula To-complete performance index (TCPI)

To-complete performance index (TCPI) is a measure of the cost performance that is required to be achieved with the remaining resources in order to meet a specified management goal, expressed as the ratio of the cost to finish the outstanding work to the remaining budget. TCPI is the calculated cost performance index that is achieved on the remaining work to meet a specified management goal, such as the Budget at Completion (BAC) or the Estimate at Completion (EAC). If it becomes obvious that the BAC is no longer viable, the project manager should consider the forecasted EAC. Once approved, the EAC may replace the BAC in the TCPI calculation. Equation: To-complete performance index (TCPI) = (BAC - EV) ÷ (BAC - AC).

Formula Definition
TCPI To-complete Cost Performance Index (many versions of this formula)
  • = (BAC - EV) ÷ (BAC - AC)

  • = (BAC - EV) ÷ (EAC - AC)

  • = Remaining Work ÷ Remaining Budget

  • TCPI Values < 1 are considered good
