What a CD rate is and how it affects your money

A CD rate is the interest percentage a bank pays you for locking your money into a certificate of deposit for a set time. When you open a CD, the bank tells you upfront: you'll get this rate, for this many months or years, and your money will earn that percentage as interest. If you withdraw before the term ends, you pay a penalty—usually a few months' worth of the interest you would have earned.

The rate is fixed, meaning it doesn't change. If you buy a one-year CD at 4.50%, you'll earn 4.50% on your deposit for the full year, even if rates drop to 2% next month. That's the trade-off: you give up access to your cash, and the bank gives you a may provide return.

CD rates vary by bank, by term length, and by how much money you deposit. A six-month CD at one bank might pay 4.25% while another pays 4.00%. A five-year CD at the same bank might pay 4.75% because you're locking money away longer. Online banks often pay higher rates than brick-and-mortar branches because their overhead is lower.

Key Takeaways

  • CD rates are fixed percentages set when you open the account and may provide for the entire term, whether rates rise or fall.
  • Longer terms usually pay higher rates than shorter ones, but you cannot access your money without paying an early withdrawal penalty.
  • Online banks typically offer higher CD rates than traditional banks because they have lower operating costs.
  • The rate you receive depends on the bank, the term length, the deposit amount, and current market conditions.
  • Your CD is insured up to $250,000 per bank by the FDIC, so the rate is risk-free as long as you hold until maturity.

Why CD rates change and what moves them

CD rates follow the Federal Reserve's benchmark interest rate, called the federal funds rate. When the Fed raises rates, banks raise CD rates to attract deposits. When the Fed cuts rates, CD rates fall. This happens because banks use deposits to make loans, and they compete for your money by offering higher rates when borrowing costs rise.

The current economic environment also matters. During periods of high inflation, the Fed typically raises rates to cool spending, and CD rates climb. During recessions or slowdowns, the Fed cuts rates to encourage borrowing, and CD rates drop. You may see rates fall sharply over a few months or stay flat for quarters at a time.

Individual banks also set rates based on how much deposit money they need. A bank flush with deposits might lower its CD rates because it doesn't need more cash. A bank that needs to grow its deposit base might offer above-market rates to pull money in from competitors.

How to compare CD rates across banks

Start by listing the term you want—three months, one year, five years—and then check rates at five to ten banks. Online banks like Marcus, Ally, and American Express Personal Savings typically post rates on their websites without requiring you to log in. Traditional banks like Chase, Bank of America, and Wells Fargo also publish rates, though they're often lower than online competitors.

Pay attention to the annual percentage yield, or APY, not just the rate. APY includes the effect of compounding—how often interest is added to your balance—so it's the true number to compare. A CD advertising 4.50% APY will earn more than one advertising 4.50% with monthly compounding if the first one compounds daily.

Also check the minimum deposit. Some banks require $500 to open a CD; others require $25,000. If you don't have the minimum, that rate is not available to you. A few banks offer no-penalty CDs that let you withdraw early without a fee, though the rates are usually lower than standard CDs.

The relationship between term length and rate

Longer terms almost always pay higher rates than shorter ones. A three-month CD might pay 4.00%, a one-year CD 4.50%, and a five-year CD 5.00%. Banks do this because they want to lock in your money for as long as possible—the longer they have your cash, the more they can lend it out and earn on it.

This pattern can flip during unusual economic moments. If the Fed is expected to cut rates soon, short-term CDs might pay nearly as much as long-term ones because banks expect rates to fall. In those cases, locking in a longer term protects you from lower rates later. Conversely, if rates are expected to rise, short-term CDs let you reinvest at higher rates when they mature.

The difference between a one-year and five-year rate can be 0.25% to 0.75%, depending on market conditions. Over five years, that gap compounds into real money. A $10,000 CD earning 4.50% for five years grows to about $12,462, while one earning 5.25% grows to about $12,762—a $300 difference from a single percentage point.

What happens to your rate when the CD matures

When your CD term ends, the bank returns your principal plus all the interest you earned. At that moment, you have a choice: renew the CD at the current rate, withdraw the money, or move it to a different bank's CD. Most banks automatically renew your CD at their current rate if you don't tell them otherwise, so check your maturity date and decide before it arrives.

If rates have fallen since you opened your CD, renewing at the new rate means earning less. If rates have risen, you might find a better rate elsewhere and move your money. Some people use a CD ladder—opening multiple CDs with different maturity dates so that part of their money matures every few months or years, letting them reinvest at current rates without locking everything away for years.

The interest you earn is taxable income in the year it's credited to your account, even if you don't withdraw it. The bank will send you a 1099-INT form showing how much interest you earned, and you'll report it on your tax return.

How CD rates compare to savings accounts and money market accounts

Savings accounts and money market accounts pay interest too, but usually less than CDs. A high-yield savings account might pay 4.00% to 4.50%, while a CD for the same term pays 4.50% to 5.00%. The trade-off is flexibility: you can withdraw from a savings account anytime without penalty, but you give up the higher rate. With a CD, you get the higher rate only if you lock your money away.

Money market accounts sit between the two. They often pay rates close to CDs but let you write checks or make a limited number of withdrawals per month. If you need some access to your cash but want a rate higher than a regular savings account, a money market account might fit better than a CD.

For money you won't need for years, a CD usually wins on rate. For money you might need within a year or two, a high-yield savings account offers nearly the same rate with no penalty for early withdrawal. The choice depends on how certain you are that you won't need the cash before the CD matures.

Early withdrawal penalties and how they work

If you withdraw money from a CD before the term ends, the bank charges a penalty—usually expressed as a number of months' 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 earning 5.00% annually, three months of interest is about $125, so the penalty is $125.

Some banks calculate the penalty differently, charging a flat fee or a percentage of the principal. Always ask what the penalty is before you open a CD. If you think there's any chance you'll need the money, factor the penalty into your decision. A no-penalty CD pays a lower rate but lets you withdraw without cost if your situation changes.

The penalty is deducted from your interest earnings first. If your interest hasn't accumulated enough to cover the penalty, the bank takes the difference from your principal. This means you can end up with less money than you deposited, which is why early withdrawal should be a last resort.

Frequently Asked Questions

Do CD rates change after I open the account?

No. Your rate is locked in when you open the CD and stays the same for the entire term. If market rates rise or fall, your rate does not change. That's the may provide of a CD—you know exactly what you'll earn from day one.

What's the difference between APY and the interest rate?

The interest rate is the percentage the bank pays. APY is the annual percentage yield, which includes the effect of compounding—how often interest is added back to your balance and starts earning interest itself. APY is always equal to or higher than the rate, and it's the number you should use to compare CDs across banks.

Can I lose money in a CD?

You cannot lose your principal if you hold the CD to maturity, because it's FDIC-insured up to $250,000. If you withdraw early, the penalty might eat into your interest or even your principal, leaving you with less than you started with. That's the only way to lose money—by breaking the CD early.

Should I open a long-term CD if rates might rise?

If you believe rates will rise soon, a short-term CD lets you reinvest at higher rates when it matures. A long-term CD locks you in at today's rate, which could be lower than future rates. However, if you're wrong and rates fall, the long-term CD protects you. The choice depends on your outlook and how much you value certainty over potential gains.

What happens if the bank fails?

Your CD is insured by the FDIC up to $250,000, so you'll get your principal and accrued interest back even if the bank fails. The FDIC takes over the CD and either transfers it to another bank or pays you out. This protection is automatic—you don't need to do anything.
