Estimate at Completion (EAC) in project management
are the expected total costs at the current time. The EAC value includes all costs that result from the actual costs plus the residual costs until completion. The residual costs can be determined from individual activities, from the costs for subprojects or for the overall project at completion. It is the cost of a particular activity sequence within the work breakdown structure and the estimated remaining cost to complete, the Estimate to Complete (ETC). Relative to a reporting date, Estimate at Completion represents the progress of the project and is a revised estimate. The EAC costs are calculated from the sum of the current costs, related to a key date, and the ETC costs, Estimate at Completion (ETC).
