CD minimums range from $500 to $25,000, depending on the bank and the CD term

There is no single price for a CD because you are not buying a product — you are lending money to a bank for a set time. What you pay is your own deposit. Most banks require a minimum deposit to open a CD, and that minimum varies widely. Online banks often ask for $500 or $1,000. Credit unions may ask for $500. Some regional banks require $2,500 or $5,000. A few institutions with premium CDs ask for $25,000 or more.

The amount you deposit is the amount you get back (plus interest) when the CD matures. You are not paying a fee to own the CD itself. However, if you withdraw your money before the maturity date, the bank will charge you an early withdrawal penalty, which is a real cost that reduces your return.

The interest rate you earn depends on the CD term (how long you lock in your money), the bank's current rates, and market conditions. Longer terms usually pay more interest than shorter ones. A 1-year CD might pay 4.5%, while a 5-year CD might pay 5.0%, but these rates change constantly and vary by institution.

Key Takeaways

  • The minimum deposit to open a CD typically ranges from $500 to $5,000 at most banks, though some require $25,000 or more.
  • You do not pay a fee to own a CD; your deposit is your own money that earns interest and returns to you at maturity.
  • Early withdrawal penalties are the main cost of owning a CD, and they can erase months or years of interest if you need the money before maturity.
  • Interest rates on CDs change based on the term length, the bank, and current market conditions, so comparing rates across institutions matters.
  • Some banks waive minimum deposits for certain account types or offer lower minimums for online-only CDs.

How early withdrawal penalties work and what they cost

If you withdraw money from a CD before it matures, the bank charges a penalty. The penalty amount is set when you open the CD and is usually stated in the disclosure document you receive. Common penalties are expressed as a number of months of interest — for example, "3 months of interest" or "6 months of interest."

If your CD earns $100 in interest over its full term and the penalty is 3 months of interest, the bank will subtract roughly $25 from your withdrawal (assuming interest accrues evenly). In some cases, the penalty is large enough that you lose principal — you get back less than you deposited. This is why early withdrawal is expensive and why CDs work best when you know you will not need the money.

A few banks offer no-penalty CDs, which let you withdraw without a penalty, but they pay lower interest rates to offset that flexibility. The trade-off is real: you give up yield to gain access.

Comparing minimums and rates across different bank types

Online banks typically have the lowest minimums and highest rates because they have lower overhead costs. You might find a $500 minimum and a 5.0% APY (annual percentage yield) at an online-only bank. A traditional brick-and-mortar bank in your town might require $2,500 and offer 4.5% APY. A credit union might split the difference: $1,000 minimum and 4.8% APY.

The difference between 4.5% and 5.0% on a $10,000 CD over 2 years is about $100 in extra interest. That is worth the time to compare, especially if you have a larger deposit. However, the lowest rate is not always the worst choice if the minimum is so high that you cannot meet it. A CD you can actually open beats a CD with a better rate that you cannot afford.

Some banks offer tiered rates: if you deposit more, you earn more interest. A bank might pay 4.5% on deposits under $10,000 and 4.8% on deposits of $10,000 or more. Check the rate sheet carefully to see whether the rate you saw applies to your deposit size.

What happens if you do not have the minimum

If you have less than the minimum deposit, you have three options. First, you can wait and save until you reach the minimum. Second, you can open a regular savings account instead, which typically has no minimum and earns interest, though usually less than a CD. Third, you can look for a bank with a lower minimum — online banks and credit unions often have smaller thresholds than traditional banks.

Some banks also offer CD ladders or stepped CDs that let you open multiple smaller CDs instead of one large one. For example, instead of opening a single $5,000 CD, you might open five $1,000 CDs with different maturity dates. This spreads your money across multiple terms and gives you access to some of your funds sooner.

Special CDs with higher minimums and higher rates

Some banks offer jumbo CDs for deposits of $100,000 or more. These pay higher interest rates because the bank is borrowing a larger sum. If you have that much to deposit, a jumbo CD might earn 0.25% to 0.5% more than a standard CD at the same institution. Over a 2-year term, that difference adds up.

Brokered CDs, sold through investment firms, sometimes have high minimums ($25,000 or more) but can offer rates that are competitive with or better than bank CDs. However, brokered CDs have different rules about early withdrawal and are not insured the same way as bank CDs, so read the terms carefully.

How to find the actual cost of a CD before you open it

Before you open a CD, you should know three numbers: the minimum deposit, the interest rate (expressed as APY), and the early withdrawal penalty. The bank must disclose all three in writing, usually in a document called a "CD disclosure" or "terms and conditions."

Read the early withdrawal penalty section carefully. Some banks state it as a flat dollar amount. Others state it as months of interest. A few state it as a percentage of the deposit. Make sure you understand which applies to your CD. If the penalty is unclear, call the bank and ask them to explain it in dollars, not percentages.

You can compare CDs across banks using a spreadsheet: list the minimum, the APY, the term, the total interest you would earn, and the early withdrawal penalty. This makes it easy to see which CD gives you the best return for your situation.

Frequently Asked Questions

Can I open a CD with less than the minimum if I have a checking account at the bank?

Some banks waive or lower the minimum for existing customers, but this varies by institution. Call your bank and ask whether they offer a reduced minimum for account holders. A few banks also waive minimums during promotional periods.

Is the interest I earn on a CD taxed?

Yes. CD interest is taxable income in the year you earn it. The bank will send you a 1099-INT form at tax time showing how much interest you earned. If you earn more than $10 in interest, the bank must report it to the IRS.

What if the bank fails while my CD is open?

Your CD is insured up to $250,000 by the FDIC (Federal Deposit Insurance Corporation) if the bank is FDIC-insured. This means you get your full deposit plus accrued interest back, even if the bank closes. Check the bank's website to confirm it is FDIC-insured before you open a CD.

Do I have to pay taxes on the early withdrawal penalty?

No. The penalty is a reduction of your own money, not income. You only pay taxes on the interest you actually earned and kept. If you withdraw early and lose part of your interest to the penalty, you pay taxes only on the interest that remains.

Can I move a CD to a different bank before it matures?

You can withdraw the money and move it, but you will pay the early withdrawal penalty. Some banks allow you to transfer a CD to another bank without penalty, but this is rare. Ask your current bank whether they offer CD transfers before you withdraw.
