CD Minimums Range From $500 to $100,000 Depending on the Bank

A certificate of deposit costs whatever you decide to deposit into it, but banks set a minimum deposit amount you must put in to open the account. That minimum is not a fee — it is the money itself. Most banks require between $500 and $2,500 to start a CD. Some online banks go as low as $100 or $250. A few banks, particularly those targeting wealthier customers, require $10,000, $25,000, or even $100,000 minimums.

The minimum you see advertised is the floor. You can deposit more than that minimum. If a bank says the minimum is $1,000, you can open a CD with $1,000, $5,000, $10,000, or any amount above that. There is no upper limit on most CDs — you can deposit as much as you want, up to the FDIC insurance cap of $250,000 per depositor per bank.

The minimum does not change based on how long you lock your money away. A 3-month CD and a 5-year CD at the same bank usually have the same minimum deposit requirement. The difference is the interest rate you earn and the penalty if you withdraw early.

Key Takeaways

  • Most banks require a minimum deposit of $500 to $2,500 to open a CD, though online banks sometimes accept $100 or $250.
  • The minimum deposit is the actual money you are putting in, not a separate fee charged by the bank.
  • You can deposit more than the minimum, and your total deposit is insured up to $250,000 by the FDIC at each bank.
  • Early withdrawal penalties vary by bank and CD term, and can wipe out months or years of interest if you break the CD before maturity.
  • Some banks waive minimums for certain account types, such as CDs opened through an employer retirement plan or linked to a checking account.

How Early Withdrawal Penalties Reduce Your Return

The cost of breaking a CD early is the early withdrawal penalty, and it comes out of your deposit and interest. If you deposit $5,000 in a 1-year CD earning 4% interest, you would earn $200 in interest. But if you withdraw after 6 months and the penalty is 6 months of interest, you lose that $200 and walk away with $5,000. If you withdraw after 3 months, you might lose $100 in interest and pay an additional penalty, leaving you with less than your original $5,000.

Penalties vary widely. Some banks charge a flat dollar amount — say, $25 or $50. Others charge a number of months of interest: 3 months, 6 months, or 12 months depending on the CD term. A few banks charge a percentage of the deposit. A 5-year CD typically has a steeper penalty than a 3-month CD at the same bank, because the bank is counting on keeping your money longer.

Before you open a CD, read the penalty terms. If you think you might need the money within the term, a shorter CD or a high-yield savings account might be a better fit. Some banks also offer no-penalty CDs, which let you withdraw without a penalty during a short window after the CD matures, though the interest rate is usually lower than a standard CD.

Interest Rates Vary by Bank, Term, and Market Conditions

The interest rate you earn on a CD is not set by the government or a central body — each bank decides its own rate. Two banks might offer very different rates on the same CD term. Online banks often pay higher rates than brick-and-mortar banks because they have lower overhead costs. Credit unions sometimes offer competitive rates to their members.

The rate also depends on how long you lock your money away. A 3-month CD typically pays less than a 1-year CD at the same bank. A 5-year CD usually pays more than a 1-year CD. The longer you commit, the higher the rate — though this is not always true, and rates can invert depending on what the Federal Reserve is doing.

Rates change constantly as market conditions shift. A CD paying 4.5% today might pay 3.8% next month, or 5.2%. If you see a rate you like, locking it in by opening the CD means you keep that rate for the full term, even if rates drop later. But if rates rise after you open the CD, you are stuck with the lower rate unless you pay the early withdrawal penalty to move your money.

FDIC Insurance Protects Your Deposit Up to $250,000

Your CD deposit is protected by FDIC insurance up to $250,000 per depositor per bank. This means if the bank fails, the FDIC will return your money up to that limit. The insurance covers the deposit itself plus any interest you have earned so far. You do not pay for this protection — it is automatic at any bank that displays the FDIC logo.

The $250,000 limit applies per bank, not per CD. If you have $150,000 in a 1-year CD and $100,000 in a 5-year CD at the same bank, both are insured because your total is $250,000. If you have $200,000 in one CD at Bank A and $200,000 in another CD at Bank B, both are fully insured because they are at different banks.

If you want to deposit more than $250,000 and keep it all insured, you can open CDs at multiple banks. Some people use a CD ladder service that spreads their deposit across several banks automatically, though you can also do this yourself by opening accounts directly.

Account Maintenance and Other Costs

Most banks do not charge monthly fees to hold a CD. The account is passive — you deposit money, it sits and earns interest, and at maturity you get your principal plus interest back. Some banks charge an inactivity fee if you do not make any transactions for a very long time, but this is rare and usually only applies if you have not touched the account in several years.

A few banks charge a fee if you request a paper statement or if you want to set up automatic renewal to a new CD when the current one matures. Read the CD terms before you open the account to see if any fees apply. Most online banks and credit unions have no fees at all.

When your CD matures, the bank will either return your money to a linked account or renew the CD automatically at the current rate. If you do not want automatic renewal, you must tell the bank before the maturity date. Some banks give you a grace period of a few days after maturity to withdraw or move the money without penalty, but do not count on it — contact the bank to confirm.

How to Compare CDs Across Banks

To find the best CD for your situation, compare the minimum deposit, the interest rate, the term length, and the early withdrawal penalty across at least three banks. Online banks and credit unions often have the lowest minimums and highest rates. Your own bank may have lower rates but higher minimums.

Use a CD rate comparison tool or visit bank websites directly to see current rates. Rates change frequently, so a rate you see today may not be available tomorrow. When you find a CD you want, open it right away if the rate meets your needs — do not wait hoping for a better rate, because rates can move in either direction.

Write down the maturity date and the renewal terms so you know when your CD matures and what will happen to your money. Set a reminder on your phone or calendar a week before maturity so you can decide whether to renew, move the money, or withdraw it.

Frequently Asked Questions

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

Most banks do not allow you to add money to an existing CD. If you want to deposit more, you typically need to open a new CD. Some credit unions and a few banks offer add-on CDs that let you deposit additional funds during a set window, but this is uncommon. Check with your bank about their policy.

What happens if I need my money before the CD matures?

You can withdraw your money early, but you will pay the early withdrawal penalty. The penalty comes out of your deposit and interest. If the penalty is larger than the interest you have earned, you will get back less than you deposited. Some banks offer no-penalty CDs that let you withdraw without a penalty during a short window after maturity, though the rate is usually lower.

Do I pay taxes on CD interest?

Yes. CD interest is taxable income in the year you earn it, even if you do not withdraw the money. The bank will send you a 1099-INT form at tax time showing how much interest you earned. If you are in a high tax bracket, a CD in a tax-advantaged account like an IRA may make more sense than a regular CD.

Is a CD a good place to put an emergency fund?

A CD is not ideal for an emergency fund because you cannot access the money without paying a penalty. A high-yield savings account is better for emergency money because you can withdraw anytime without penalty, and rates are competitive with short-term CDs. Use a CD for money you know you will not need for several months or years.

Can I open multiple CDs at the same bank?

Yes. You can open as many CDs as you want at the same bank, and each one is insured separately up to $250,000. Many people open CDs with different maturity dates — a strategy called a CD ladder — so that one CD matures every few months and they can reinvest at current rates without locking all their money away for the same length of time.
