Prediction: This Investment Will Beat 5-Year CDs

CDs can be a smart way to lock in an interest rate and get steady income from savings that you aren't likely to need for a while. However, they are best suited for income and aren't necessarily a great way to build wealth over time.

As of this writing, it's rather easy to find 5-year CDs with guaranteed APYs in the 4.00%-4.50% range from the top online banks. But for long-term wealth building, there's no comparison between CDs and the stock market.

CDs vs. stocks

Getting a return of 4% or 4.5% from a 5-year CD is certainly a respectable amount of income, especially from a risk-free investment. For people under 35 years old who are reading this, the current CD interest rate environment is the best it's been in your adult life.

However, if you're hoping to build long-term wealth, there's simply no more surefire way than the stock market.

You don't need to buy individual stocks or find the next big trend to achieve excellent returns. Even opening a brokerage account and buying a basic index fund that tracks the benchmark S&P 500 index can be a surprisingly strong wealth creator over time. In fact, from 1965 through the end of 2023, the S&P 500 produced annualized returns of 10.2%

Here's what this means. Let's say that you have $20,000 to invest that you want to use to build a nest egg for the future. Even if you can get a 4.50% APY on 5-year CDs forever, this amount of money will compound to about $74,900 after 30 years.

On the other hand, simply using the 10.2% annualized return of the stock market, a $20,000 investment would grow to more than $368,000 over a 30-year period. And that assumes a one-time investment. Imagine if you added a few thousand dollars to your investment every year along the way.

Both investment types have pros and cons

To be sure, both CDs and stock market investments have pros and cons. The long-term return potential of the stock market is certainly an advantage, but the downside is that stocks can be rather volatile over shorter periods.

In fact, during the 1965-2023 period I mentioned earlier, the total returns from the stock market in a single year have been as high as 38% or as low as negative 37%. On the other hand, CDs have lower long-term return potential, but the value of your investment is 100% safe.

For this reason, financial planners (including myself) generally suggest that investors keep their assets in a mix of stock-based investments and fixed-income instruments, which includes CDs. One popular rule of thumb is known as the "rule of 110," and says that if you subtract your age from 110, you'll get the ideal percentage of your portfolio to keep in stocks, with the rest in fixed income.

For example, I'm 42 years old, so this implies that I should have 68% of my money in stocks, and the other 32% in fixed-income instruments.

The idea is that while you're younger and have decades to let your money ride out the ups and downs of the market, that's when the bulk of your money should be in stocks. On the other hand, as you get older and your focus becomes more about income than growth, that's when instruments like 5-year CDs make the most sense.
