What CD rates are and why they matter

A certificate of deposit (CD) is a savings account where you agree to leave money untouched for a set period — usually three months to five years — in exchange for a higher interest rate than a regular savings account. The bank pays you that rate regardless of what happens to market rates while your money sits there. When the term ends, you get your principal back plus the interest earned.

CD rates vary by bank, by how long you lock your money away, and by how much you deposit. A bank offering 4.5% on a one-year CD might offer 5.2% on a five-year CD, or a different bank might offer 4.8% on that same one-year term. Shopping around matters because the difference between 4.5% and 5.2% on $10,000 over one year is $70 in your pocket — or not.

The tradeoff is access: you cannot touch the money without paying an early withdrawal penalty, usually three to six months of interest. That penalty exists because the bank counts on keeping your money for the full term.

Key Takeaways

  • CD rates are fixed for the entire term and do not change, even if market rates rise or fall after you open the account.
  • Longer terms usually pay higher rates, but you cannot access the money without losing some or all of the interest you earned.
  • Different banks offer different rates for the same CD term, so comparing rates across at least three banks is worth the time.
  • Online banks typically offer higher CD rates than brick-and-mortar banks because they have lower overhead costs.
  • The early withdrawal penalty is the main cost of breaking a CD early, and it varies by bank and by how long you have held the account.

How CD rates are set and what moves them

Banks set CD rates based on what the Federal Reserve does with short-term interest rates. When the Fed raises its benchmark rate, banks eventually raise CD rates to attract deposits. When the Fed cuts rates, CD rates fall. The lag between a Fed move and a bank's response is usually a few weeks to a few months.

The term length also drives the rate. A three-month CD pays less than a five-year CD because the bank can lend out your money for longer and earn more from it. You are being paid for tying up your cash. If you think rates will fall, locking in a longer term at current rates makes sense. If you think rates will rise, a shorter term lets you reinvest at a higher rate sooner.

Bank size and funding needs matter too. A small regional bank might offer a higher rate than a large national bank to pull in deposits it needs for lending. Online banks almost always beat brick-and-mortar rates because they do not pay for branches, tellers, or physical overhead.

Where to find and compare current CD rates

The fastest way to see what is available is to check rate-comparison websites like Bankrate, DepositAccounts, or the FDIC's BankFind tool. These sites update daily and let you filter by term length, deposit amount, and bank type. You can see what five banks are offering on a one-year CD in minutes.

Call or visit the websites of banks you already use, plus at least two online banks you do not. Online banks like Marcus, Ally, and American Express Personal Savings often lead on rates. Regional banks sometimes beat them on specific terms. Write down the rate, the term, the minimum deposit, and the early withdrawal penalty for each one you are considering.

Rates change frequently, especially when the Fed is moving. If you find a rate you like, open the CD within a day or two. A rate quoted on Monday might be lower by Wednesday.

Minimum deposits and how they affect your options

Most banks require a minimum deposit to open a CD, typically $500 to $2,500. Some online banks have no minimum. A few banks offer higher rates if you deposit $25,000 or more, but you do not need that much to get a competitive rate.

If you have $5,000 to invest, you can open CDs at multiple banks to spread the money around. You might put $2,500 in a one-year CD at one bank and $2,500 in a two-year CD at another. This approach, called CD laddering, lets you access some of your money each year while keeping some locked in at higher rates. It also keeps all your deposits under the $250,000 FDIC insurance limit at each bank.

Early withdrawal penalties and when they apply

If you need your money before the CD matures, the bank will charge you an early withdrawal penalty. This penalty is usually stated as a number of months of interest. A CD with a three-month penalty means you lose three months of the interest you earned. On a $10,000 CD at 5% annual rate, that is about $125.

Some banks charge the penalty only if you withdraw before a certain date — say, 30 days after opening. Others charge it no matter when you withdraw. A few banks offer no-penalty CDs, which pay a slightly lower rate but let you withdraw without losing interest. These make sense if you are not sure you can leave the money alone.

Before you open a CD, read the disclosure document the bank provides. It will spell out the exact penalty, when it applies, and whether any interest is forfeited. Do not assume all CDs at the same bank have the same penalty.

FDIC insurance and how it protects your money

CDs at banks insured by the FDIC are covered up to $250,000 per depositor, per bank, per account type. This means if the bank fails, you get your money back up to that limit. If you have $250,000 in a one-year CD and $250,000 in a five-year CD at the same bank, both are covered because they are different account types.

If you want to put more than $250,000 into CDs, open accounts at different banks. A $300,000 CD at Bank A and a $300,000 CD at Bank B are both fully insured. The FDIC website has a tool to calculate your coverage at any bank.

Credit unions offer similar insurance through the National Credit Union Administration (NCUA), also up to $250,000. The protection works the same way.

Comparing CD rates across different term lengths

A typical rate curve shows longer terms paying more. A one-year CD might pay 4.5%, a three-year CD 4.8%, and a five-year CD 5.1%. But this is not always true. Sometimes a one-year CD pays more than a two-year CD if the Fed is expected to cut rates soon. Check the rates for each term you are considering rather than assuming longer always means higher.

Think about when you will need the money. If you know you will want to buy a car in two years, a two-year CD locks in current rates and gives you the cash when you need it. If you might need it sooner, a shorter term or a no-penalty CD costs less in penalties if plans change. If you will not touch it for five years, the five-year rate is usually worth the wait.

Frequently Asked Questions

Can I add money to a CD after I open it?

No. A CD is a fixed contract — you deposit a lump sum at the start, and that amount earns interest for the full term. You cannot add to it. If you want to invest more money, you open a separate CD.

What happens when my CD matures?

The bank will notify you before the maturity date, usually 10 to 30 days before. You can then renew the CD at the current rate, move the money to a savings account, or withdraw it. If you do nothing, many banks automatically renew at the current rate, so check the terms to avoid being locked in at a lower rate.

Are CD rates the same at every bank?

No. Rates vary by bank and change daily. An online bank might offer 5.2% on a one-year CD while a national bank offers 4.6% for the same term. That is why comparing rates across at least three banks before you commit is worth doing.

Is a CD better than a high-yield savings account?

CDs usually pay more, but you cannot touch the money without a penalty. High-yield savings accounts pay less but let you withdraw anytime. If you need access to the money within a year, a savings account makes more sense. If you know you will not need it, a CD's higher rate is worth the restriction.

What if I need my money before the CD matures?

You can withdraw it, but you will pay an early withdrawal penalty — usually a few months of interest. Some banks offer no-penalty CDs that let you withdraw without losing interest, though they pay a lower rate. Calculate whether the penalty is worth it before you break the CD early.
