Short-term certificate of deposit (CD) accounts offer investors a safe opportunity to squirrel away money for a future expense. If you’re looking for a brief solution for storing your cash and want to earn more interest than a typical savings account will offer, a 6 month CD can make a lot of sense. (It’s also a good place to start if you’re building a CD ladder.)

Using information from, a database of offerings at more than 17,100 banks and credit unions, we found the five banks and five credit unions with the top 6-month CD rates. If there was a tie, we chose the institution with the smaller minimum deposit requirement. The national average APY on 6-month CDs (among banks and credit unions) is 0.22% as of October 2021, according to the database. These options outperform that average by a long shot. (You may also want to view our picks for the overall best CD rates for more options.)

Pros and cons of using 6-month CDs


  • Rates higher than savings accounts: The CD rates offered by banks and credit unions are generally higher than those on savings accounts.
  • Fixed rates: The rates are fixed and guaranteed for the length of their term.
  • Money available upon maturity: The discipline of keeping the funds in the CD means the money will be available upon maturity. (Note: Most banks offer a seven-day grace period to reinvest or withdraw the investment, after which the funds will roll over into a new CD. However, you are not guaranteed the same rate.)


  • Lower rates compared to longer terms: Six-month CD rates are lower than those offered on longer CD investment terms.
  • Early withdrawal penalties: To tap into the CD funds — even for emergencies — consumers must accept a loss through penalties, which can include a percentage of the funds, a percentage of the earned interest, or a combination of both. A typical penalty on a short-term CD is between 30 and 90 days’ worth of interest earnings. If you’re not confident you can do without access to the funds for six months, you may be better off putting your money in a traditional savings account, which is likely to earn less interest than a CD.
  • Rollovers can reset rates: Since CD rollovers may reset at a different percentage rate, consumers must speak with the bank before the grace period ends to ensure they are getting the best deal.

Using a 6-month CD for laddering

A CD ladder comprises small-amount CDs with varying terms and respective interest rates that contribute to a long-term investment strategy. After the 6-month CD matures, investors can withdraw the funds for a predetermined expense. Or, they can reinvest the money into a longer-term CD with a better rate. By staggering the maturity dates on short-term CDs, consumers have access to their cash on a regular, predictable basis.

Where can you open a CD account?

Consumers can open 6-month CD accounts (or longer) from banks and credit unions. Bank and credit union CD rates are based on Federal Reserve rates, and there may be strategic times to pursue these short-term instruments following a rate increase.
