Definition
A projection of the budget deficit or surplus, expressed as BAC - EAC.
Variance at Completion (VAC) in plain English
Picture a road trip budget: you planned 1,000 (BAC), you've spent 600 so far, and based on how fast you're burning cash you project the whole trip will cost $1,200 (EAC). The gap between the plan and that projection is the kind of story Variance at Completion (VAC) is trying to tell — not a random accounting label, a forecast of whether you'll finish over or under. Hold onto this precise job description: A projection of the budget deficit or surplus, expressed as BAC - EAC. On a stem, name whether Variance at Completion (VAC) is about timing, ownership, measurement, or delivery style — then eliminate the answer that borrows a cousin concept from the wrong phase.
