What is the difference between EAC and ETC?

Question

In earned value management, what is the difference between the Estimate At Completion and the Estimate To Completion? Are these two terms equivalent?

Answer 1

EAC = Estimate at Completion which means the project TOTAL estimated cost when the project will be complete. Some call this forecast.

ETC = Estimate to complete = remaining cost = the cost of the remaining work.

Comments

EAC refers to the projected cost at the completion of the project, this situvation araises when BAC has been subjected to revision. Then the mathematical formula could be EAC = AC+ ETC.  AC refers to the actual cost incured till date.
ETC being the projected cost to execute the balance work for completion of the project.

Is it explained properly pl confirm thanks
