How does a 3-month CD work and what are the benefits of investing in one?

A 3-month CD, or certificate of deposit, is a type of investment where you deposit money with a bank for a fixed period of 3 months. During this time, the bank pays you interest on your deposit. The benefit of investing in a 3-month CD is that it offers a guaranteed return on your money and typically has higher interest rates compared to a regular savings account. Additionally, the money is locked in for the duration of the CD, which can help prevent impulsive spending.
