What are the different types or variations of CDs?

There are several types of Certificates of Deposit (CDs), including traditional CDs, which have fixed interest rates and terms; bump-up CDs, which allow for a one-time interest rate increase; and no-penalty CDs, which permit early withdrawal without a penalty. Additionally, there are variable-rate CDs, where interest rates can fluctuate over time, and brokered CDs, which are purchased through a brokerage and may offer different terms and rates. Each variation caters to different financial needs and investment strategies.
