How to Open a CD at Your Bank or Credit Union

You buy a CD by walking into your bank or credit union, calling them, or going to their website and selecting the CD product. You'll choose how long to lock your money away — typically three months to five years — and the bank will tell you the interest rate for that term. You then deposit your money, and the bank holds it until the maturity date. On that date, you get your principal back plus the interest earned.

The process takes minutes if you already have a checking or savings account at that institution. If you don't, you'll need to provide your Social Security number, a government ID, and proof of address. Some banks let you open a CD online without visiting a branch. Others require you to come in person or call a representative.

The minimum deposit varies widely. Some banks accept $500; others require $1,000, $5,000, or more. Credit unions often have lower minimums than large national banks. Ask about the minimum before you commit, because you won't be able to withdraw the money early without paying a penalty.

Key Takeaways

  • You purchase a CD by depositing money with a bank or credit union for a fixed time period, during which the rate does not change.
  • The interest rate depends on the term length you choose and the current rates the bank is offering — longer terms usually pay more.
  • You can buy a CD in person, by phone, or online, and the process takes only a few minutes if you have an existing account.
  • Withdrawing money before the maturity date triggers an early withdrawal penalty, which is typically a few months of interest.
  • You can ladder CDs by buying multiple CDs with different maturity dates so that money becomes available at regular intervals.

Understanding CD Terms and Interest Rates

The term is how long your money stays locked in the CD. Common terms are three months, six months, one year, two years, three years, and five years. The longer the term, the higher the interest rate the bank will pay you — this is because the bank gets to use your money for a longer period.

The interest rate is the percentage the bank pays you each year on your deposit. If you buy a one-year CD for $5,000 at 4.5% annual percentage yield (APY), you'll earn roughly $225 in interest over the year, though the exact amount depends on how the bank compounds interest. The rate is locked in when you buy the CD and does not change, even if the bank raises or lowers rates later.

Rates vary by bank and by the day you open the CD. A large national bank might offer 3.5% on a one-year CD while a smaller regional bank or credit union offers 4.2% for the same term. It's worth calling or checking websites of several institutions before you decide where to put your money.

Where to Buy CDs and What to Compare

You can buy CDs at traditional brick-and-mortar banks, online banks, and credit unions. Online banks often pay higher rates because they have lower overhead costs. Credit unions sometimes pay competitive rates and may offer better terms to members. Traditional banks are convenient if you want to speak to someone in person, but their rates are often lower than online competitors.

When comparing CDs across institutions, look at three things: the interest rate, the term length, and the early withdrawal penalty. A CD paying 4.8% for one year is not a good deal if the penalty for taking your money out early is six months of interest. Read the fine print or ask the bank directly what the penalty is before you commit.

Some banks offer special promotions with higher rates for new customers or for larger deposits. These rates are real but temporary — they may only be available for a limited time or only for customers opening their first CD at that bank. Check whether the promotional rate applies to the term you want.

What Happens When Your CD Matures

When the maturity date arrives, the bank will contact you and tell you what happens next. You have a grace period — usually seven to ten days — to decide what to do with your money. During this window, you can withdraw the money, move it to a savings account, or roll it into a new CD.

If you don't take action during the grace period, most banks automatically renew your CD into a new one with the same term at the current interest rate. This is convenient if you want to keep the money locked away, but the new rate may be lower than what you earned before. Check your bank's renewal policy and set a calendar reminder for a few days before maturity so you can decide whether to renew or withdraw.

Some banks let you renew online or by phone. Others require you to visit a branch. If you want to move the money to a different bank, ask your current bank how to transfer it — most will send it directly to another institution without requiring you to withdraw it first.

Early Withdrawal Penalties and How to Avoid Them

If you need your money before the maturity date, the bank will charge you an early withdrawal penalty. This penalty is usually expressed as a number of months of interest. A CD with a three-month penalty means you lose three months' worth of the interest you would have earned. On a $10,000 CD paying 4% APY with a three-month penalty, you'd lose about $100.

The penalty amount depends on the term. Longer-term CDs usually have larger penalties. A five-year CD might have a penalty of six months of interest, while a one-year CD might have a penalty of three months. Ask the bank what the penalty is before you buy — it's printed in the disclosure document, but it's worth asking directly so you understand it clearly.

If you think you might need the money, consider buying a shorter-term CD instead, or splitting your money across multiple CDs with different maturity dates. This strategy, called laddering, lets you access some of your money regularly without penalties. For example, you could buy five one-year CDs, each maturing in a different year, so one matures every year.

CD Laddering: Spreading Your Money Across Multiple Terms

CD laddering is a way to earn higher rates while keeping some of your money accessible. Instead of putting all your money in one CD, you divide it among several CDs with different maturity dates. When each CD matures, you can withdraw the money or roll it into a new longer-term CD.

Here's a straightforward example: you have $5,000 to invest. Instead of buying one five-year CD, you buy five one-year CDs with $1,000 each. Each year, one CD matures and you can withdraw the money or reinvest it. This way, you're not locked in completely, and you can take advantage of higher rates if they rise in the future.

Laddering works best when you have a larger amount to invest and when you want to balance safety with some flexibility. It requires more attention than buying a single CD, because you'll need to decide what to do with each maturity. But it gives you regular access to your money without early withdrawal penalties.

FDIC Insurance and Safety

CDs at banks are protected by FDIC insurance up to $250,000 per depositor, per bank, per account type. This means if the bank fails, the government guarantees you'll get your money back up to that limit. CDs at credit unions are protected by a similar program called NCUA insurance, also up to $250,000.

If you have more than $250,000 to invest, you can protect all of it by spreading it across multiple banks or credit unions. Each institution's FDIC or NCUA coverage is separate, so $250,000 at Bank A and $250,000 at Bank B are both fully protected.

This insurance covers the principal and the interest you've earned. It does not cover losses from early withdrawal penalties, so if you withdraw early and lose interest to a penalty, that loss is not covered by insurance. The insurance only protects you if the bank itself fails.

Frequently Asked Questions

Can I withdraw money from a CD before it matures?

Yes, but you'll pay an early withdrawal penalty. The penalty is usually a few months of interest and is set by the bank when you open the CD. Some banks offer no-penalty CDs that let you withdraw without a penalty, but these pay lower interest rates.

What's the difference between a CD and a savings account?

A CD locks your money away for a set time and pays a higher interest rate. A savings account lets you withdraw money anytime without penalty but pays lower interest. CDs are for money you don't need to touch; savings accounts are for emergency funds or money you might need soon.

Do I have to pay taxes on CD interest?

Yes. The interest you earn on a CD is taxable income. The bank will send you a 1099-INT form at tax time showing how much interest you earned. You report this on your tax return. The interest is taxed as ordinary income at your regular tax rate.

What happens if I don't do anything when my CD matures?

Most banks automatically renew your CD into a new one with the same term at the current interest rate. The new rate may be higher or lower than your previous rate. You have a grace period of about seven to ten days to stop the renewal and withdraw your money instead.

Is it better to buy a long-term CD or a short-term CD?

Long-term CDs pay higher rates but lock your money away longer. Short-term CDs pay lower rates but give you access to your money sooner. If you don't need the money for several years, a longer term usually makes sense. If you might need it sooner, a shorter term or a ladder of multiple CDs is safer.
