The estimate at completion (EAC) is one of the measures used to check whether a project is on track. It is "the expected total cost of completing all work expressed as the sum of the actual cost to date and the estimate to complete (ETC).
There are multiple formulas to calculate the EAC:
|EAC=BAC/CPI||If the CPI (cost performance index) is expected to be the same for the remainder of the project.|
|EAC=AC+BAC-EV||If future work will be accomplished at the planned rate.|
|EAC=AC+bottom-up ETC||If the initial plan is no longer valid.|
