CD rates vary widely across financial institutions, with the highest rate at 4.1% APY as of October 26, 2025. Marcus by Goldman Sachs, Sallie Mae, and Synchrony offer competitive rates on their CDs. The amount of interest earned depends on the APY, with higher rates leading to more significant earnings.

Investing $1,000 in a one-year CD with 1.70% APY and monthly compounding interest would yield $17.13 in interest. Choosing a one-year CD with 4% APY would result in $40.74 in interest. Depositing more in a CD leads to higher earnings, with $10,000 earning $407.42 in interest at 4% APY.

When choosing a CD, consider factors beyond the interest rate, such as the type of CD. Bump-up CDs allow for a rate increase, no-penalty CDs offer flexibility in withdrawals, jumbo CDs require higher deposits for potentially higher rates, and brokered CDs are purchased through a brokerage with potential for higher rates but more risk.
