A CD locks your money away for a set time in exchange for a may provide interest rate

A certificate of deposit (CD) is an account where you give the bank a lump sum of money and agree not to touch it for a fixed period — usually three months to five years. In return, the bank pays you a fixed interest rate, which is almost always higher than what you'd earn in a regular savings account. The bank uses your money during that time and pays you back the full amount plus interest when the term ends.

The trade-off is straightforward: you get a better rate, but your money is locked up. If you withdraw before the term is over, you pay a penalty — usually a few months' worth of interest. The bank tells you the penalty amount upfront, so you know the cost before you open the account.

CDs are one of the safest places to put money because they're insured by the FDIC (Federal Deposit Insurance Corporation) up to $250,000 per account at each bank. That means even if the bank fails, you get your money back.

Key Takeaways

  • You deposit a fixed amount of money and agree not to withdraw it for a set period, typically three months to five years.
  • The bank pays you a fixed interest rate that does not change, regardless of what happens to market rates during your term.
  • If you withdraw early, you pay a penalty that the bank discloses before you open the account, usually equal to a few months of interest.
  • Your money is FDIC-insured up to $250,000, so your principal is protected even if the bank fails.
  • When the term ends, you can withdraw your money and interest, open a new CD, or let the bank automatically renew the account.

How the interest rate and term length work together

The longer you lock your money away, the higher the interest rate the bank will offer you. A three-month CD might pay 4.5 percent, while a five-year CD at the same bank might pay 5.2 percent. The bank is willing to pay more because it gets to use your money for longer.

The rate you receive is fixed, meaning it does not change. If you open a one-year CD at 5 percent, you earn 5 percent for the full year, even if the Federal Reserve raises interest rates and new CDs start paying 6 percent. This is both a protection and a risk: you're protected from rates falling, but you miss out if rates rise.

Interest compounds on most CDs, usually daily or monthly. That means you earn interest on your interest. A $10,000 CD at 5 percent compounded daily will earn slightly more than one compounded monthly, though the difference is small.

What happens when your CD term ends

When your CD reaches its maturity date, the bank sends you a notice — usually 10 to 14 days before — telling you what happens next. You have three main options: withdraw the money, open a new CD, or let the bank automatically renew your account into a new CD at the current rate.

If you do nothing, most banks automatically renew your CD into a new term at the same length. The interest rate will be whatever the bank is currently offering for that term, not the rate you had before. This is important: if rates have fallen, your new rate will be lower. You typically have a grace period (often 7 to 10 days after maturity) to withdraw without penalty if you don't want the renewal.

If you withdraw the money, you receive your original deposit plus all the interest you earned. There is no penalty because you're withdrawing at the end of the term, not before it.

Early withdrawal penalties and when they explore

If you need your money before the maturity date, you can withdraw it, but you'll pay a penalty. The bank calculates this penalty as a certain number of months of interest. A CD might have a penalty of three months' interest, meaning if you withdraw after six months of a two-year CD, you lose three months' worth of what you would have earned.

The penalty is deducted from your interest, not from your principal. So you always get your original deposit back, but you may get less interest than you expected. In some cases, if you withdraw very early, the penalty might exceed the interest you've earned, and you'd actually lose money compared to what you deposited.

The bank discloses the exact penalty in the account agreement before you open the CD. Read this number carefully — it varies widely between banks and between different CD terms at the same bank. Some banks charge more for early withdrawal from longer-term CDs.

How CDs compare to savings accounts and money market accounts

A regular savings account has no lock-up period — you can withdraw whenever you want. But the interest rate is much lower, often 0.01 to 0.5 percent. A CD pays more because you're giving up that flexibility.

A money market account sits in the middle. It typically pays more than a savings account but less than a CD, and you can usually withdraw your money without penalty, though there may be limits on how many withdrawals you can make per month.

If you know you won't need the money for a specific period and want the highest may provide rate, a CD is the right choice. If you might need the money sooner, a savings account or money market account is safer, even if the rate is lower.

Laddering CDs to balance rate and access

Some people use a strategy called CD laddering to get higher rates while still having access to some of their money regularly. You open multiple CDs with different maturity dates — for example, one that matures in one year, one in two years, one in three years, and one in four years. As each CD matures, you can withdraw the money or reinvest it in a new longer-term CD.

This approach gives you regular access to portions of your money without paying early withdrawal penalties. It also lets you take advantage of rising interest rates: when a CD matures and rates have gone up, you can open a new one at the higher rate instead of being locked in at an old rate.

Laddering works best when you have a larger amount to invest and you're comfortable managing multiple accounts. For smaller amounts or shorter time horizons, a single CD or a savings account is usually simpler.

Where to open a CD and what to compare

You can open a CD at any bank or credit union. Online banks typically offer higher rates than brick-and-mortar banks because they have lower overhead costs. The tradeoff is that you manage everything online or by phone — there's no local branch to visit.

When comparing CDs, look at three things: the interest rate, the term length, and the early withdrawal penalty. A CD with a 0.5 percent higher rate might not be worth it if the early withdrawal penalty is much steeper. Use a CD calculator (available on most bank websites) to see how much you'll actually earn.

Make sure the bank is FDIC-insured. You can check this on the FDIC's website by searching for the bank's name. If you're opening a CD at a credit union, check that it's insured by the NCUA (National Credit Union Administration) instead — the coverage is the same.

Frequently Asked Questions

Can I withdraw money from a CD before it matures?

Yes, but you'll pay an early withdrawal penalty set by the bank. The penalty is usually a few months of interest. The bank discloses this penalty before you open the account. You always get your original deposit back, but you may receive less interest than expected.

What happens if interest rates rise while my CD is locked in?

Your rate stays the same for the full term. You don't benefit from the rate increase, but you're also protected if rates fall. When your CD matures, you can open a new one at the current higher rate if you want.

Is my money safe in a CD if the bank fails?

Yes. CDs are FDIC-insured up to $250,000 per account at each bank. If the bank fails, the FDIC guarantees you get your full deposit and interest back, up to that limit.

What's the difference between a CD and a savings account?

A CD locks your money for a set period and pays a higher interest rate. A savings account lets you withdraw anytime but pays much less interest. Choose a CD if you won't need the money soon and want the highest rate; choose a savings account if you need flexibility.

Do I have to renew my CD when it matures?

No. When your CD matures, you can withdraw the money with no penalty, open a different CD, or let the bank automatically renew it. If you do nothing, most banks automatically renew at their current rate for the same term length, which may be higher or lower than your previous rate.
