5.70% Is Still the Best Nationwide Rate

Note that the “top rates” quoted here are the highest nationally available rates Investopedia has identified in its daily rate research on hundreds of banks and credit unions. This is much different than the national average, which includes all banks offering a CD with that term, including many large banks that pay a pittance in interest. Thus, the national averages are always quite low, while the top rates you can unearth by shopping around are often 5, 10, or even 15 times higher.
