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).
