Within earned value analysis, the CV (earned value cost variance) field is calculated as BCWP - ACWP. It is the difference between how much it should have cost to achieve the current level of completion on the task and how much it has actually cost to up to the status date or the current date. A positive CV value indicates that progress against the task, summary task, project or resource is ahead of the baseline cost (under budget) and a negative value indicates that progress is currently over budget.
