We did this actually. We put some inheritance money into a 5-year CD with Ally to get their highest rate and then took it out after less than a year after our situation changed. It wasn't exactly intentional, but we chose that option because of the lenient terms. We lost 60 days of interest, yes, but we still received all the remaining earnings which were higher than we would have earned in their savings account (which we also have and are very happy with) even after the penalty. The withdrawal process was actually pretty easy, just a phone call and a quick conversation with a representative. She did ask why we were withdrawing it, and I told her, and that was it. Took a few days to show up in our checking account with a different bank.
