Certificates of deposit are low-risk savings tools that offer a stable way to grow your money over time

Certificates of deposit are investment vehicles that earn interest on a fixed sum of money over a set term

CDs come in varying term lengths, from three- or six-month commitments to decadelong terms. Typically, the longer the term, the higher the interest rate.

CDs come with risks, such as penalties for early withdrawal and inflation

CDs are generally considered fairly safe investment options. A CD bought via a federally insured bank is insured up to $250K.

Different CDs can have different term lengths, interest rates, and more

For instance, if a bank needs more deposits to fund loans, then it may offer high interest rates to attract deposits. Alternatively, a large bank with sufficient deposit reserves may have less incentive to grow its CD portfolio, offering lower rates as a result.
