A CD can be a smart way to grow your money safely.
A certificate of deposit can give you some much-needed security in an economy that feels anything but certain. Your CD rate is fixed when you open the account, so your returns are guaranteed for the entire term.
What might those returns look that? That depends on which account you choose. The best CDs earn annual percentage yields up to 4.50%, but the national average for some terms is less than a third of that.
Here’s a look at how much interest you could rack up if you open one of these top accounts and deposit $5,000 today. We’ll also show you your potential earnings with some other amounts.

The national average for a one-year CD is 1.75% APY as of July 15, 2025, while the average for a one-year CD for the top banks tracked at CNET is 4.00% APY. What difference does that make for your interest earnings?
The value at maturity for a one-year CD with the national average APY would be $5,081.00 if you deposit $5,000. However, if you deposit $5,000 into a one-year CD earning 4.40% APY — the top APY among one-year CDs we track — you’d end up with a total value of $5,220.00.
How much can you earn by depositing other amounts?
If you want to put more — or less — money into a CD, you can still earn a competitive interest rate. Here are some examples of interest earnings for other deposit amounts.

How interest on a CD is calculated
The APY on your CD represents the rate of return you’ll receive on your cash over 12 months. CDs earn compound interest, which means you earn interest on your initial deposit amount and any interest earned to date.
All banks compound interest differently. Your CD may compound interest daily, weekly or monthly. The more frequently the interest compounds, the more money you earn. You can use a CD calculator to figure out exactly how much interest your CD could earn.
How to select the right CD for you
When you’re looking for a CD, a good APY matters, but there are other important factors to consider, too. Ask yourself these questions when you’re choosing a CD:
- When will I need my money? Each CD has a set term, and you can’t withdraw your money during the term without paying an early withdrawal penalty. CD terms typically range from six months to five years, so pick one that fits your timeline.
- Do I meet the minimum deposit requirements? Some CDs have no minimum deposit requirement, but others may require a deposit of $1,000 or more. How much money you have to put into a CD can help narrow down your options.
- What are the costs? Some CDs charge fees, such as monthly maintenance or early withdrawal fees. These fees can eat into your earnings. Read the fine print for any CD you’re considering so you know what you’re signing up for.
- Is the bank insured? CDs at banks insured by the Federal Deposit Insurance Corporation and credit unions insured by the National Credit Union Administration are protected for up to $250,000 per account, per person. Look for CDs from these institutions to keep your money safe.
