Estimate at Completion (EAC)is a forecasting tool in EVM that predicts the total cost of the project at completion based on current performance.

Key Points:

EAC Formula:

One common method to calculate EAC is:

EAC = ACWP + (BAC - BCWP)

Where:

ACWP is the Actual Cost of Work Performed,

BAC is the Budget at Completion,

BCWP is the Budgeted Cost of Work Performed.

Explanation:

This formula assumes that the remaining work will be performed at the budgeted rate (i.e., future work will follow the planned performance), and it adjusts the total estimate by adding the cost of the remaining work to the actual costs incurred so far.

Conclusion:The correct answer isD. ACWP + (BAC - BCWP)because this method provides a reliable estimate for the total project cost at completion, considering current performance.
