Which earned value management formula can help you determine how likely it is that you'll complete the program based on the amount of cash left in the program budget?

Estimate at Completion (EAC) projects the expected total final cost of the program based on current performance, but does not express the efficiency ratio needed to stay within remaining funds.

Variance at Completion (VAC = BAC - EAC) shows the expected budget surplus or deficit at completion, but does not indicate the performance efficiency required on remaining work.

TCPI = (BAC - EV) / (BAC - AC), where BAC is the Budget at Completion. This formula directly answers whether the remaining budget is achievable by showing the performance ratio required on all future work - if TCPI is significantly greater than 1.0, completing on budget is unlikely given current performance trends.

Estimate to Complete (ETC) forecasts the remaining cost to finish the work but does not express it as a performance efficiency ratio relative to remaining budget.
