A CD has no upfront cost to open, but you do have to deposit money

A Certificate of Deposit costs nothing to open — no process fee, no account setup charge, no monthly maintenance fee. What you pay is the money itself. You choose how much to deposit when you open the CD, and that entire amount sits in the account earning interest until the CD matures.

The bank holds your deposit for a set period — typically three months to five years, depending on the CD you choose. During that time, you cannot withdraw the money without paying an early withdrawal penalty. That penalty is the real cost most people encounter, and it varies by bank and by CD term.

Key Takeaways

  • Opening a CD costs nothing, but you must deposit a minimum amount that varies by bank — often $500 to $2,500, though some banks accept $100 or less.
  • Early withdrawal penalties are the main cost you might face, and they typically equal three to six months of interest on your deposit.
  • The penalty amount depends on your CD's term length and your bank's rules, so you should ask before you open the account.
  • No monthly fees, no inactivity fees, and no charges for letting the CD mature on schedule — you only pay if you break the terms early.

Minimum deposit requirements vary by bank and CD type

Most banks require a minimum deposit to open a CD. This is not a fee — it is the money that goes into the account. Common minimums are $500, $1,000, or $2,500, but some banks accept $100 or even $50. Online banks often have lower minimums than brick-and-mortar branches.

A few banks offer no-minimum CDs, though these are less common. If you are starting with a small amount, call or visit the bank's website to check their specific minimum before you decide where to open the CD.

Early withdrawal penalties: what they are and how much they cost

If you need your money before the CD matures, the bank charges an early withdrawal penalty. This penalty is subtracted from your interest earnings or from your principal deposit, depending on the bank and how much interest you have earned.

Penalties are usually expressed as a number of months of interest. A three-month penalty on a $1,000 CD earning 4% annually would cost roughly $10 (three months of the $40 annual interest). On a longer-term CD or a larger deposit, the penalty is higher because the monthly interest is higher.

Some banks use a flat dollar amount instead — for example, $25 or $50 — but most use the months-of-interest method. The exact penalty depends on your CD's term length. A three-month CD might have a one-month penalty, while a five-year CD might have a six-month penalty. Always ask the bank what the penalty is before you open the account.

No other fees if you follow the CD terms

Banks do not charge monthly maintenance fees on CDs, inactivity fees, or fees for letting the CD mature on schedule. Once the CD reaches its maturity date, you can withdraw your money and interest with no penalty. The bank will either send you a check, transfer the funds to another account, or automatically renew the CD into a new term — depending on what you choose when you open it.

If you do nothing when the CD matures, most banks automatically roll it into a new CD at the current rate. You can prevent this by telling the bank in advance how you want to handle the maturity, or by contacting them before the maturity date arrives.

How interest rates affect what you earn, not what you pay

The interest rate on your CD determines how much money you earn, not how much you pay. A higher rate means more interest accumulates in your account. When the CD matures, you get back your original deposit plus all the interest earned.

Interest rates vary by bank, by CD term length, and by market conditions. A three-month CD might pay 4.5%, while a five-year CD at the same bank might pay 4.8%. Longer terms usually pay more because you are locking your money away for a longer time. You do not pay anything for a higher rate — you straightforward earn more.

Special CDs with different cost structures

Most CDs follow the standard model: no opening cost, a minimum deposit, and an early withdrawal penalty. But some banks offer variations.

No-penalty CDs let you withdraw your money early without a penalty, but they typically pay a lower interest rate than standard CDs. You trade higher earnings for flexibility.

Bump-up CDs let you increase your interest rate once during the term if rates rise, usually at no cost. Some banks charge a small fee for this feature, but many do not.

Add-on CDs let you deposit more money into the CD after you open it, sometimes without resetting the maturity date. These work the same way cost-wise — no fee to add money, but the early withdrawal penalty still applies to the entire balance.

What happens when your CD matures

When your CD reaches its maturity date, you have choices. You can withdraw the full amount (principal plus interest) with no penalty. You can move the money to a savings account, checking account, or another CD. Or you can let the bank automatically renew it into a new CD at the current rate.

If you do not give the bank instructions before maturity, most will renew automatically. This is not a cost — it is just what happens by default. If you want to do something different, contact the bank a few days before the maturity date and tell them your preference.

Frequently Asked Questions

Can I withdraw my money from a CD before it matures?

Yes, but you will pay an early withdrawal penalty. The penalty is usually three to six months of interest, though it varies by bank and CD term. Some banks offer no-penalty CDs that let you withdraw early without a fee, but these pay lower interest rates.

Do I have to pay taxes on CD interest?

Yes. Interest earned on a CD 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. This is not a cost you pay to the bank — it is income tax you owe to the government.

What if I need my money and cannot afford the early withdrawal penalty?

You have a few options. Some banks will waive the penalty if you explain a hardship, though this is not may provide. You could take out a personal loan instead of breaking the CD. Or you could wait until the CD matures if you can manage without the money for a few more months.

Is there a cost to renew a CD when it matures?

No. When your CD matures and you choose to renew it, there is no fee or cost. You straightforward move into a new CD term at the current interest rate. If you do not want to renew, you can withdraw your money with no penalty.

Do online banks charge different CD fees than traditional banks?

Online banks typically have lower or no minimum deposits and sometimes lower early withdrawal penalties than traditional banks, but they charge the same zero opening fee. The main difference is that online banks often pay higher interest rates because they have lower overhead costs.
