HALF OF THE BUDGET FOR EACH ELEMENT IS RECORDED AT THE TIME THAT THE WORK IS SCHEDULED TO BEGIN AND THE OTHER HALF AT THE TIME THE WORK IS SCHEDULED TO BE COMPLETED.
FOR A PROJECT WITH A LARGE NUMBER OF ELEMENTS THE AMOUNT OF DISTORTION FROM SUCH A PROCEDURE IS MINIMAL.

Estimated Cost At Completion
Budget at completion
The estimate at completion is the best estimateof the total cost at the completion of the project.
The EAC is a periodic evaluation of the status of the project - usually on a monthly basis or until a significant change has been identified.
Progress reporting needs to answer four fundamental questions:
1. Where are we today (time and cost)?
2. Where will we end up (time and cost)?
3. What are the present and future risks?
4. Are there any special problems that need to be
addressed and what can management do to help?

2. ESTIMATE AT COMPLETION (EAC)
EAC = (360/340) X 579,000 = $613,059
Overrun = 613,059 - 579,000 = $34,059
3. COST SUMMARY
Costs are running approximately 5.9% over budget due to higher salaried labor.
4. SCHEDULE SUMMARY
The 24.4% behind schedule condition is due to subtasks 4 and 6 which have not yet begun due to lack of raw materials and the 50/50 method for booking costs. Overtime will get us back on schedule but at an additional cost of 2.5% of direct labor costs.
