The VAC is a forecast of what the variance, specifically the Cost Variance (CV), will be upon the completion of the project. It is the size of the expected cost overrun or underrun. In many situations the project manager must request additional funding as early as possible, or at least report the potential for an overrun. The VAC represents the size of this … [Read more...]

## Estimate at Completion (Earned Value Analysis)

In earned value analysis, the Estimate At Completion, usually abbreviated EAC, is the estimate of the final project cost given the past performance of the project. Thus, it allows the project manager to see what the final project cost estimate is. The EAC is one of four calculations in the Earned Value Management which allow you to forecast the future performance of … [Read more...]

## Estimate to Complete (Earned Value Analysis)

In earned value analysis, the Estimate To Complete, usually abbreviated ETC, is the expected remaining cost to complete the project. It is not the final overall project cost (that's the EAC), rather it is the expenditure from now to the end of the project. It does not include what has already been spent. Thus, it allows the project manager to compare the funding needs … [Read more...]

## The Earned Value Formulas

Earned Value is a method of calculating project status. It does this from two perspectives: Time (schedule) and Cost. After applying the earned value method the project manager will know whether the project is: behind or ahead of schedule. over or under budget. In this post we will outline each formula in the earned value management system. The first three … [Read more...]

## Budget at Completion (Earned Value Analysis)

The Budget at Completion (BAC) is a value used in earned value management, a division of project management. It represents the original project budget. For example, if a project has a budget of $10,000, BAC = $10,000 Therefore, there is no other formula or calculation for this metric. The BAC is often compared to the Estimate at Completion (EAC) … [Read more...]

## The Earned Value Method

Everybody has heard of a project whose cost spiralled out of control. Even big megaprojects where the difference measures in the billions are not immune to cost pressures. In fact, they are even more likely to go over budget. What is the official project management methodology for controlling project costs? To answer this question, we consult the … [Read more...]

## How to Perform the Earned Value Calculations

The earned value method is the project management standard for cost control during a project. Whether you are a practicing project manager or studying for the PMP exam, you need to know how to calculate earned value. Fortunately, it involves nothing more than basic high school math. The more difficult part is knowing what each of the variables means and how … [Read more...]
