What term length should you get?

The longer the term, the higher the rate tends to be. Terms typically range from three months to five years, so see how CDs fit in with your savings goals. Most have early withdrawal penalties, so be sure you won’t need your money before the term expires.

How much interest will you earn on a CD?

This varies based on your deposit, CD rate and term length. For example, a $10,000 deposit in a five-year CD with 0.70% APY will earn about $355 in interest, while a CD with 0.01% APY, all other factors the same, only earns $5 in interest. » Want to see other calculators?

How do CD rates work?

CD rates are quoted as an annual percentage yield, or APY, which is how much the account earns in one year including compound interest. Banks and credit unions generally compound interest monthly or daily. An interest rate is similar to APY but before factoring in compound interest. For more details, see our explainer on APY.

What should I know when choosing CDs?

• Prioritize finding a high interest rate. Not every bank has competitive rates on their CDs. See our list of the best CD rates.

• Avoid early withdrawal fees. Although short-term CDs mean less time to wait to access your money and less need to incur the penalty to get money early, long-term certificates mean a beefier rate.

What happens if I withdraw a CD early?

Generally a CD has an early withdrawal penalty, which tends to range from a few months' to a year's worth of interest earned depending on the bank and the CD's term length. Longer lengths usually have bigger penalties. They only occur if you take out money before a CD term expires. Try our calculator to see dollar amounts for what an early withdrawal penalty costs.

When will CD rates go up?

It partly depends on when the Federal Reserve raises its benchmark rate again, which might not be for a while. Federal Reserve actions are one factor in banks’ decision to change rates. Check where historical CD rates have been.

Are there other accounts I should consider?

An online brokerage account is an option if you’ve already built a robust emergency fund and want to boost your long-term savings. Although these financial products come with more risk than CDs, they could lead to higher returns.

Picking the right broker comes down to your priorities. Some investors are willing to pay more for a top-notch platform; others count costs above all else. With brokerage accounts, you don't have to worry about early withdrawal penalties, but your funds may be more difficult to access in a pinch, given that you’ll likely need to sell some investment shares before you can devote that money to anything else.
