In it’s simplest form ETC is the Original Cost Budget (BAC) minus Actual Costs (AC). We can illustrate this as ETC = BAC – AC. Estimate At Completion (EAC): A perpetual forecast of the future value of the project at completion.
Are EAC and ETC the same?
EAC (Estimate at Completion) and ETC (Estimate to Complete) are two important dimensions of Earned Value Management. … EAC is a revised estimate of cost budget based on current situation.
How do you calculate EAC and etc?
- EAC = AC + Bottom-up ETC. This formula is used when the original estimation is fundamentally flawed. …
- EAC =BAC/Cumulative CPI. This formula is used when the original estimation is met without any deviation. …
- EAC = AC + (BAC – EV) …
- EAC = AC + [BAC – EV / (Cumulative CPI x Cumulative SPI)]
