That's about it. That's pretty much it.
앞서 어떠한 이야기나 설명을 한 경우에 마무리하는 말로써 위 표현으로 이야기 또는 설명의 중요한 부분을 전달하였음을 나타낼 수 있다.
That's about it! and That's pretty much it! are basically the same. You use one of these when you have finished telling your story or when you have finished your explanation of something. It means that you have covered all the main points of the story or explanation, though you may have left out some less important details. It may mean that you just can't think of anything more to say on the subject.
