Should you put your money in a long-term CD or invest it? Here's what to consider (2024)

With savings rates still high and interest rate cuts possible in 2024, savers today are giving a lot of attention to CDs.

A certificate of deposit, or CD, lets you lock in a fixed interest rate for a fixed amount of time. That's an attractive option in today's market, where savers can find CD rates above 5%. This return far outpaces the current inflation rate, so your money is protected from being devalued.

But the CD term length you choose is a big factor when deciding whether to lock up your money in a CD or put it into the stock market instead. Here's what CNBC Select wants you to know.

Sara Kalsman, a certified financial planner at robo-advisor Betterment, says deciding between a CD or the market is a "very timely" scenario that's top of mind for her clients.

"Most importantly, it comes down to what the individual is looking to achieve and what their investment time horizon looks like," Kalsman tells CNBC Select.

Your time horizon is how long you'll need to keep those funds invested in order to realize your specific goal, whether it's growing your emergency fund, saving for a down payment on a house or building a nest egg for retirement.

Your investment time horizon should line up with your saving or investing strategy. CD terms range from short-term (one year or less) and mid-term (two to three years) up to long-term (four years or longer).

For the short term — say, six months or a year — CDs can be a smart financial tool to grow your savings fairly risk-free. We've compared dozens of offerings and found that one-year CDs currently have the strongest returns.

CIBC Bank USAoffers a 5.36% APY on its one-year CD, the highest we've found for any term. There is a minimum deposit of $1,000 required, although CIBC has a range of terms and dozens of physical locations across six states.

When you look at longer-term CDs, however, putting your money in the market may make more sense. A 10-year Discover® Certificate of Deposit has a decent 3.75% APY, for example, but that pales in comparison to the average stock market return for the last 10 years, which has been about 12.39% as measured by the S&P 500 Index (or 9.48% when adjusted for inflation).

Longer-term CDs also have less liquidity since savers are typically subject to penalties if they withdraw before the maturity date.

Kalsman generally holds off on recommending 10-year CDs and says she doesn't see other financial advisors endorsing them, either. Not many banks even offer CDs with 10-year terms — the few that do include Discover®, Vio Bank, EmigrantDirect and MySavingsDirect.

"I'm a huge fan of liquidity," Kalsman says.

Many ETFs track a market index, like the Vanguard 500 Index Fund (VOO), which follows the S&P 500.
