## Calculating Estimate at Completion – An Illustrative Formula

When a project is 50% complete and the actual cost (AC) is \$8,500 instead of the projected \$7,750, it indicates a variance in the budget. To calculate the Estimate at Completion (EAC) in this scenario, the EAC = AC + (BAC – EV) formula can be used. This formula takes into account the actual cost and adjusts for the variance by incorporating the remaining budget.

The EAC formula is essential in project management as it helps in predicting the final cost of the project based on the current performance. In this case, the AC is \$8,500, which represents the actual cost incurred up to the 50% project completion mark. The BAC (Budget at Completion) is the total budget for the project, which was initially projected to be \$7,750. The EV (Earned Value) represents the value of the work actually completed at this point in the project.

Using the EAC formula, we can calculate the adjusted estimate at completion by adding the remaining budget (BAC – EV) to the actual cost (AC). This adjustment accounts for the variance in the budget and provides a more accurate prediction of the final project cost. The formula helps in considering the previous performance issues and adjusting the estimate accordingly.

The EAC = AC + (BAC – EV) formula can be represented in a table for clarity:

Variable Value
AC (Actual Cost) \$8,500
BAC (Budget at Completion) \$7,750
EV (Earned Value) Value at 50% project completion
EAC (Estimate at Completion) AC + (BAC – EV)

By using the EAC = AC + (BAC – EV) formula, project managers can make informed decisions about resource allocation, budget adjustments, and overall project planning. It provides a method to account for deviations from the initial budget and helps in forecasting the final cost based on the current project performance.
