# Difference between EAC and ETC

Hello,

As both Estimate At Completion (EAC) and Estimate To Complete (ETC) related to cost forecasting. I have confusion that both are asking for how much estimated cost at that particular point from the project. Please anyone can explain in detail. Thanks

Hi @joshipiyush,

At any given point during the project:

For example, initially my estimate to complete the project was $100,000 (BAC).

2 months into the project, I have already spent $30,000, and after reviewing the remaining work, I expect to spend addition $80,000 on the project.

So, $80,000 is my ETC, and overall the project is expected to cost $30,000 + $80,000 = $110,000. This is my EAC.

Hope that helps.

Thanks Harwinder..

Thanks Harwinder Paaji. I also wanted to know this.

Best, KK

Hi everybody,

Thanks Harwinder for his explanation and also the example. In order to get complete information on this subject, you can also study about EVM (Earned Value Management);

in fact, there are different parameters (from basic to detail) in this area. You can first get familiar with

PV, EA & AC, then the indices of Project Variance and Performance (SV, CV, SPI & CPI) and finally you can calculate the EAC & ETC (which are well explained by Harwinder).Thanks and regards...
