Methods for Calculating EAC
1. EAC = Actual Cost (AC) + Estimate to Complete (ETC)
This approach is based upon the thought that the next cost performance will be similar to now. It estimates the EAC by combining the value of the actual costs that already occurred at the time of the report (AC) with the anticipated costs that are yet to be incurred up to the point of completion of the project (ETC).
2. EAC = Budget at Completion (BAC) / Cost Performance Index (CPI)
This method, reflecting on the project’s past cost performance, is used. The Cost Performance Index (CPI) is the ratio of the Earned Value (EV) to the Actual Cost (AC). The EAC is calculated by dividing the BAC by the CPI and it will reflect whether there are overruns or under-runs.
3. EAC = AC + (BAC – EV)
By assessing both past cost experience and the earned value of the project, this approach assumes both the cost performance and the so-called earned value. It comes to the extent of EAC by adding the actual costs realized (AC) and then deducting BAC minus EV.
Through this approach, the model goes to give different measures that will give us insights into how our project is likely to move from the historical performance and current status. The question of method will be dealt with due to the complicity of project factors, the previous performance data reliability, and the mayhem of changes in the remaining work.
What Is Estimate at Completion in Project Management (EAC)?
Estimate at Completion (EAC) is a crucial concept in project management, providing project managers with a forecasted total cost based on current performance and expenditures. By evaluating actual costs and estimating remaining expenses, EAC helps project teams anticipate the financial requirements for successful project completion. The utilization of various calculation methods adds flexibility to adapt projections as projects evolve, enhancing the precision of cost predictions.
