A fixed term savings account locks your money away for a set period in exchange for a higher interest rate

A fixed term savings account (also called a certificate of deposit or CD) is a deal between you and a bank: you give them your money for a specific length of time — usually three months to five years — and they promise to pay you a higher interest rate than a regular savings account would. The catch is that you cannot touch the money until the term ends without paying a penalty.

The bank uses your locked-in money to make loans to other customers, so they reward you for leaving it alone. The longer you agree to lock it up, the higher the rate they typically offer. A one-year CD might pay 4% annual interest, while a five-year CD might pay 4.5% — the exact rates change constantly and vary by bank.

This is different from a regular savings account, where you can withdraw money whenever you want but earn almost no interest. It is also different from a money market account, which offers higher rates but usually requires a larger opening deposit and lets you write checks or make transfers (with limits).

Key Takeaways

  • Fixed term accounts pay a set interest rate for a set time period, and that rate does not change even if the bank raises rates for new customers.
  • You pay a penalty if you withdraw money before the term ends, usually equal to several months of the interest you would have earned.
  • The interest rate you receive depends on the length of the term, the amount you deposit, and current market conditions — longer terms usually pay more.
  • Your money is insured by the FDIC up to $250,000, so the bank failing does not mean you lose your deposit.

How the interest rate and term length work together

When you open a fixed term account, the bank tells you two things: the annual percentage yield (APY) and the maturity date. The APY is the interest rate you will earn, expressed as a yearly number. If you deposit $5,000 at 4.5% APY for one year, you will earn roughly $225 in interest (the exact amount depends on how the bank calculates daily interest, which varies slightly).

The maturity date is when your term ends and the bank returns your principal plus all the interest you earned. On that date, you have a choice: withdraw the money, or let the bank automatically roll it into a new fixed term account at whatever rate they are offering at that moment. Many banks do this automatically unless you tell them to stop, so check your account statements around the maturity date if you do not want your money locked up again.

The relationship between term length and rate is not fixed — it depends on what is happening in the broader economy. When the Federal Reserve is raising interest rates, banks often pay more for longer terms because they are betting rates will keep climbing. When rates are falling, the difference between a one-year and five-year rate might be tiny. You cannot predict which way rates will move, so there is no "right" term length — only the one that matches when you actually need the money.

What happens if you need the money before the term ends

If you withdraw money before the maturity date, the bank charges an early withdrawal penalty. This penalty is usually stated as a number of months of interest. A common penalty might be "three months of interest," which means if you were earning $100 per year and you withdraw after six months, you lose $25 (three months' worth) from your earnings.

The penalty comes out of your interest, not your principal — you always get your original deposit back. But if you withdraw very early, the penalty can eat up all your interest and leave you with less than you would have earned in a regular savings account. This is why fixed term accounts only make sense if you genuinely will not need the money until the term ends.

Some banks offer "no-penalty" CDs that let you withdraw without a penalty, but they pay a lower interest rate to compensate. These are worth considering if you are not completely sure you will not need the money, because the lower rate might still beat a regular savings account and you keep your flexibility.

FDIC insurance and what it protects

Your fixed term account is insured by the FDIC (Federal Deposit Insurance Corporation) up to $250,000 per account owner, per bank. This means if the bank fails, the FDIC will return your principal and all earned interest up to $250,000. You do not have to do anything to get this protection — it is automatic at any FDIC-insured bank.

The $250,000 limit applies per bank, not per account. If you have a fixed term account and a regular savings account at the same bank, they count toward the same $250,000 limit. If you have $200,000 in a fixed term account and $100,000 in a savings account at the same bank, only $250,000 total is insured. The extra $50,000 is not protected.

If you want to insure more than $250,000, you can open accounts at different banks — each bank's $250,000 limit is separate. You can also open accounts in different names (like a joint account with your spouse) at the same bank, and each name gets its own $250,000 limit.

When a fixed term account makes sense for your money

A fixed term account works best when you have money you know you will not need for a specific amount of time. Common situations include saving for a down payment on a house two years from now, setting aside money for a known expense three years away, or parking an emergency fund you have already built up and want to earn more on.

It does not work well if you are still building an emergency fund, because you might need to access that money unexpectedly. It also does not work if you have high-interest debt like credit card balances — you should pay those down first, because the interest you pay on debt is almost always higher than the interest you earn on savings.

The interest rate matters, but it is not the only thing to compare. A bank offering 4.75% for one year is not automatically better than one offering 4.5% if the first bank charges a higher early withdrawal penalty or requires a larger minimum deposit. Read the full terms before you open an account.

How to compare fixed term accounts across banks

Start by deciding how long you can lock the money away. If you know you need it in two years, only look at two-year terms — do not be tempted by a higher rate on a five-year term you cannot actually use.

Then check the APY, the minimum deposit required, and the early withdrawal penalty at several banks. 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. You can compare rates on sites like Bankrate or DepositAccounts, which list current rates from many banks, though you will still need to read each bank's full terms.

Pay attention to whether the rate is promotional (offered for a limited time to new customers) or standard. A promotional rate might drop when your term renews. Also check whether the bank automatically renews your account at maturity or sends you a notice first — you want to know what will happen to your money on the day it matures.

The difference between fixed term accounts and other savings options

A regular savings account lets you withdraw money anytime with no penalty, but pays almost no interest — often 0.01% or less. A money market account pays more interest than a savings account and lets you write checks or make transfers, but usually requires a larger opening deposit (often $2,500 or more) and limits how many transfers you can make per month.

A fixed term account pays more than either of those, but locks your money away. A high-yield savings account (offered by online banks) pays almost as much as a fixed term account but keeps your money accessible — the tradeoff is that the rate can change at any time, whereas a fixed term rate is locked in for the full term.

If you want the highest possible rate and can truly lock the money away, a fixed term account wins. If you want flexibility and a decent rate, a high-yield savings account is often the better choice. If you need to access your money frequently but want more than a regular savings account pays, a money market account splits the difference.

Frequently Asked Questions

Can I add more money to a fixed term account after I open it?

No. Once you open a fixed term account, you cannot add deposits to it. If you want to save more money at the same rate, you would need to open a separate fixed term account. Some people open multiple CDs on a schedule — one maturing every year, for example — so they can access some money each year without penalties.

What is the difference between a CD and a fixed term savings account?

They are the same thing. "CD" stands for certificate of deposit, which is the formal name. Banks use both terms interchangeably. You might also hear "term deposit" or "time deposit," which mean the same thing.

Do I pay taxes on the interest I earn?

Yes. The interest you earn on a fixed term account is taxable income. The bank will send you a 1099-INT form at the end of the year showing how much interest you earned, and you report that on your tax return. This is true even if you do not withdraw the money — you owe taxes on interest earned, not just interest withdrawn.

What happens if interest rates go up after I open my account?

Your rate stays the same until the term ends. This is both good and bad: if rates fall, you are glad you locked in a higher rate. If rates rise, you are stuck earning less than new customers. You cannot change your rate mid-term, but you can withdraw early and open a new account at the higher rate — you just pay the early withdrawal penalty.

Is there a minimum amount I have to deposit?

Yes, but it varies by bank. Some banks require as little as $500, while others require $2,500 or more. Online banks often have lower minimums than traditional banks. Check the specific bank's requirements before you open an account.
