Variance at completion

Earned Value Management Handbook, Published by the Association for Project Management in March 2013 suggests that variance at completion (VAC) is: ‘…the cost comparison of the budget at completion with the current estimate at completion.’

Variance at completion can be calculated as:

VAC = Budget At Completion (BAC) – Estimation At Completion (EAC)


VAC% = (VAC/BAC) x 100
