High-yield savings accounts are great. They allow you to set aside money in a safe place to earn a respectable return. But did you know you could save even more by using certificates of deposit?

Certificates of deposit (often simply called CDs) are time deposits. You give your money to a bank and then promise not to touch it for a specific length of time. In general, the longer you agree to let the bank keep your money, the higher the interest rate you’ll receive. And the best CD rates generally pay more interest than you can earn in a savings account.

Have you been able to find CD rates that are even better than the ones listed here? If so, please let us know. Don’t forget to include all the details: name of the bank, state, rate, when you opened this account with this rate and whether one can you open an account online or have to come in person. I’d like to find the best CD rates to share with Get Rich Slowly readers.
