Usually it's if you want to take a course just for interest, but don't want to do the work/risk getting a bad grade that brings down your GPA. Like...say I'm interested in the cold war and whatnot but don't want to write essays or anything because I'm terrible at them. I could audit the on USA in the 1960s, go to all the lectures and learn the material, without having to spend all that time doing readings and research and writing essays and getting a low grade at the end of it.
This past year I audited two courses because I was exempt from them, having taken equivalents here at Mac four years ago. The courses are heavily memorization-based and I forgot a lot of the material, so I audited them. This way I'd get a refresher on the course content without having to spend time studying.
