Research methodology
Bankrate’s editorial team regularly updates rates featured on this page about every two weeks. We mainly look for the highest APYs and break ties using the minimum balance to open a CD. Bankrate’s editorial team has reviewed nearly all of the banks and credit unions that it tracks, and researches rates weekly for more than 70 popular banks and credit unions. These institutions were selected because they offer competitive APYs, are larger (based on the amount of deposits or assets), frequently appear in internet searches or other possible factors. These banks and credit units typically offer accounts that are available nationwide. All of these banks are insured by the Federal Deposit Insurance Corp. (FDIC) and all of the credit unions are National Credit Union Administration (NCUA) credit unions, insured by the National Credit Union Share Insurance Fund (NCUSIF). Choosing an FDIC-insured bank or NCUA-backed credit union ensures your money is safe as long it’s within insurance limits and guidelines.

How we determine the national average rates
The "Bankrate.com National Average," or "national survey of large lenders," is conducted weekly. The results of this survey are quoted in our weekly articles and national media outlets. To conduct the National Average survey, Bankrate obtains rate information from the 10 largest banks and thrifts in 10 large U.S. markets. In the Bankrate.com national survey, our Market Analysis team gathers rates and/or yields on banking deposits, loans and mortgages. We've conducted this survey in the same manner for more than 30 years, and because it's consistently done the way it is, it gives an accurate national apples-to-apples comparison.
