What's the benefit of opening a Certificate of Deposit (CD) Account?
One reason why you can get a better rate with a CD compared to a regular savings account is that they lock you into that account for the period of the CD. You can get out of the CD early, but you will forfeit some of the interest. You also generally can't move a portion of the money out of the CD, you have to pull it all out, and then start a new CD with the portion you don't spend. You have to check the terms and conditions for that particular CD.  Some people use them to hold their emergency fund. This is the 3-6 months of expenses you set aside in case of a major problem such as a medical emergency or a job loss. The rate is better than the regular savings account, so it can come closer to inflation. The goal is preservation of capital, not investing for the future. So if you understand the risks, and the CD is backed with the same guarantees as the savings account, then it is a viable way to store some or all of the emergency fund.
