Variance At Completion (VAC) per Project. Variance at Completion (VAC) is a project management key performance indicator that shows the difference (in dollars) between the starting project budget (Total Budgeted Cost) and the forecasted project budget when the project is complete (Estimate at Completion or EAC).
The Schedule Variance (SV) determines whether a project is ahead of or behind schedule. It is calculated by subtracting the Planned Value (PV) from the Earned Value (EV). A positive value indicates a favorable condition and a negative value indicates an unfavorable condition.he Schedule Variance can be expressed as a percentage by dividing the Schedule Variance (SV) by the Planned Value (PV). In other words, the project is 33 percent behind schedule, meaning that 33 percent of the planned work has not been accomplished.
