Your rate is locked in when you open a CD, and your funds are protected by federal deposit insurance, so you'll enjoy low-risk, predictable returns in any economy. And in an economy as shaky as today's, these perks can be especially valuable.
Today's best CDs can earn up to 4.50% annual percentage yield (APY). That's more than three times the national average for some terms. What will that look like for your bottom line? To give you an idea, here's how much interest you'll net by depositing $5,000 into a top CD today.

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.
