Result Interpretation

EAC – CPI-Based Forecast (Project Cost Management) calculator computes Estimate at Completion (EAC) in USD using the defined engineering formula and the input values provided. Estimate at Completion (EAC) is expressed in USD. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Budget at Completion (BAC) = 100000
  • Cost Performance Index (CPI) = 0.95

Expected Result:

  • Estimate at Completion (EAC) = 105263.15789474

Engineering Interpretation:

Under the given input conditions, the calculated result is: Estimate at Completion (EAC) = 105263.15789474 USD.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.
