Have $10,000 to put into a 3-year CD? Here's how much interest you could earn now

Finding a safe place for your savings has been a relatively rewarding task over the last few years. While the interest rate environment has shifted considerably from its post-pandemic peak, savers can still find certificate of deposit (CD) accounts paying returns that would have been difficult to come by earlier in the decade. And for those who don't need immediate access to their cash, locking in one of those top CD rates can provide some valuable predictability.

And, that rate predictability alone could be a particularly important factor to consider right now. After all, the interest rate landscape remains uncertain this September, and changes in the Federal Reserve's monetary policy could eventually affect what banks are willing to pay depositors. A CD eliminates some of that uncertainty because its annual percentage yield (APY) generally remains fixed for the entire term, even if comparable savings rates fall afterward.

But choosing the right CD isn't just about finding the highest APY. The term matters, too, particularly if you're committing a meaningful amount of money. So, if you have $10,000 available and are considering a 3year CD, how much could you earn in interest at today's competitive rates?

The top 3-year CDs currently offer rates between about 4.35% and 4.50%. And, while the difference between those rates may look relatively minor, it's important to understand that even a fraction of a percentage point can affect your total earnings over a multi-year term.

Assuming the interest compounds annually and you leave both your original $10,000 deposit and the interest earned untouched until maturity, here's what you could earn on that balance after three years:

So, at today's competitive rates, putting $10,000 into a three-year CD could add roughly $1,363 to $1,412 to your savings by the time the account matures. And unlike returns from investments such as stocks, those earnings won't depend on what happens in the markets during that period.

That said, the difference between the highest and lowest rates in this example is only about $49 over three years. That doesn't mean you should ignore the APY when comparing CD accounts , but it does mean other factors can matter almost as much as the rate. For example, a CD paying 4.40% at a bank you prefer could ultimately be a better fit than a 4.50% account with a high minimum deposit requirement or unfavorable early withdrawal penalty.

It also pays to shop around and compare your options. The most competitive 3-year CD rates may not be available at the bank where you already keep your checking or savings account. Online-only banks and credit unions can offer higher APYs, so comparing several options before depositing your $10,000 could help you maximize what you earn.

A 3-year CD can offer an appealing combination of safety and predictability, but the longer commitment means you'll want to be relatively certain that you won't need the $10,000 before the account matures.

One of the biggest advantages to opening a 3-year CD now is the ability to lock in today's rate for an extended period.
