The budget at completion (BAC) is the total operating budget allocated for the project. In the earned value reporting system, the BAC is a point that is at the end of the BCWS or PV line on the chart (see EARNED VALUE REPORT). Since the BCWS line is a plot of the budget for each task in the project over time, the point at the end of the line is over the point in time when the project is scheduled to be complete and the point on the vertical axis corresponding to the end of the line is the total project budget.
Note that the BAC does not include the allowance for the contingency budget and the management reserve. As the contingency and management reserves are used, they will be removed from the reserves and added to the operating budget as needed and approved.
