Best CD rates today, Sunday, August 30, 2026: Lock in up to 4.30% APY

Today marks a noteworthy day in the realm of certificate of deposit (CD) interest rates, as the highest rate available stands at an impressive 4.30% APY. This substantial rate is currently being offered by Synchrony Bank on its 16-month CD, and Marcus by Goldman Sachs on its 18-month CD.

Interest rates for CDs can fluctuate significantly among different financial institutions, making it crucial for savers to shop around and secure the most advantageous rate for their savings. CD interest compounds on a daily or monthly basis, which further amplifies the potential earnings based on the annual percentage yield (APY).

The APY represents the total return on investment after one year, accounting for both the base interest rate and the frequency of compounding. For instance, a $1,000 investment in a one-year CD with a 1.52% APY would yield a total of $1,015.20 after a year, encompassing $15.20 in interest. Conversely, a one-year CD with a 4% APY would result in a balance of $1,040.74, generating $40.74 in interest over the same period.

While the interest rate is a primary consideration when selecting a CD, there are various types of CDs with distinct features and benefits. These include bump-up CDs, which allow for the adjustment of the interest rate if the bank's rates increase during the CD term, no-penalty CDs that permit withdrawal of funds without penalty, jumbo CDs that require a higher minimum deposit and often offer higher interest rates, and brokered CDs, which can be obtained through a brokerage and may provide higher rates or more flexible terms, albeit with potential added risks and possible lack of FDIC insurance.

The selection of the optimal CD depends on factors such as investment timeline and financial objectives. This story outlines the top CD rates available today across various terms, including 6-month, 1-year, 18-month, and 2-year CDs, and offers insights into securing the best possible rate for one's savings.
