A fixed rate savings account locks in one interest rate for a set period

A fixed rate savings account is a savings product where your bank or credit union agrees to pay you the same interest rate for a specific length of time — typically three months to five years. You deposit money, the rate stays the same no matter what happens to market rates, and you earn interest on a predictable schedule. The tradeoff is that you usually cannot withdraw the money without a penalty, and you cannot move to a higher rate if rates rise.

The rate is fixed from the day you open the account until the maturity date — the day the term ends. If you opened a one-year fixed account at 4.50% in January, you earn 4.50% for all twelve months, even if the bank raises rates to 5.25% in June. That protection works both ways: if rates fall to 3.75%, you still earn 4.50%.

When the term ends, the account matures. Your bank will either return the money to your regular savings account, let you withdraw it, or automatically roll it into a new fixed account at whatever rate the bank is offering that day. You control what happens next — the bank cannot keep your money or force you into a new term without your consent.

Key Takeaways

  • The interest rate on a fixed account does not change for the entire term, whether rates rise or fall in the broader market.
  • Early withdrawal usually costs you a penalty — typically three to six months of interest, though some banks charge more.
  • Fixed accounts are offered in terms ranging from three months to five years, and longer terms usually pay higher rates.
  • When your term ends, you decide whether to withdraw the money, move it elsewhere, or let the bank roll it into a new fixed account.
  • Fixed accounts are FDIC-insured at most banks and NCUA-insured at credit unions, up to $250,000 per account owner.

How the rate and term length affect what you earn

The interest rate you receive depends on the term you choose and what the bank is offering that day. Longer terms almost always pay more than shorter ones. A three-month fixed account might pay 4.00%, while a two-year account at the same bank might pay 4.75%, and a five-year account might pay 5.10%. The bank pays more for longer terms because it has the use of your money for a longer period and faces less risk that you will withdraw it.

The actual dollar amount you earn is straightforward math. If you deposit $10,000 in a one-year account at 4.50%, you earn $450 in interest (assuming straightforward interest, which most banks use for savings accounts). That $450 is usually added to your account at the end of the year, or sometimes monthly or quarterly — the frequency varies by bank. Some banks compound interest daily, which means you earn a tiny amount of interest on the interest itself, but the difference is usually small on savings accounts.

The rate you see advertised is the Annual Percentage Yield, or APY. This is the actual return you will get in a year, including the effect of compounding. It is always equal to or higher than the stated interest rate, but the difference is usually less than 0.01% on savings accounts.

The penalty for taking your money out early

If you need the money before the term ends, you can withdraw it, but the bank will charge an early withdrawal penalty. The penalty is usually stated as a number of months of interest. A common penalty is three months of interest — if your account pays 4.50% annually and you withdraw after six months, you lose three months of the interest you earned, keeping only three months' worth.

Some banks state the penalty differently: as a flat dollar amount, or as a percentage of the balance. A few banks charge six months of interest or more, especially on longer-term accounts. Before you open a fixed account, look at the disclosure document or ask the bank directly what the penalty is. It is usually listed on the account agreement or the product page on the bank's website.

The penalty applies only if you withdraw before maturity. Once the term ends, you can withdraw without any cost. If you are not sure you will need the money for the full term, a shorter-term account or a regular savings account with no withdrawal restrictions might be a better choice.

Fixed accounts versus regular savings accounts and money market accounts

A regular savings account has no term and no withdrawal restrictions — you can take money out whenever you want. The tradeoff is that the interest rate is usually lower and can change at any time. A bank might pay 0.01% on a regular savings account and 4.50% on a one-year fixed account. Over a year, that difference adds up significantly on larger balances.

A money market account sits between the two. It usually pays more than a regular savings account but less than a fixed account, and you can withdraw money without a penalty. Some money market accounts have limits on how many withdrawals you can make per month, though federal rules changed in 2020 and most banks removed those limits. Money market accounts are useful if you want a higher rate but need access to your money.

The choice depends on when you will need the money. If you know you will not touch it for two years, a two-year fixed account usually pays more. If you might need it sooner, the flexibility of a regular savings or money market account is worth the lower rate.

What happens when your fixed account matures

On the maturity date, your bank will send you a notice — usually 10 to 30 days before the term ends — telling you what will happen next. You have three main options: withdraw the money, move it to a different account at the same bank, or let the bank automatically roll it into a new fixed account.

If you do nothing, most banks will roll the money into a new fixed account at the current rate for the same term length. If you had a one-year account, it rolls into a new one-year account. If rates have risen, you benefit. If rates have fallen, you are locked in at the lower rate. Some banks give you a grace period — usually 7 to 10 days after maturity — during which you can withdraw without penalty. After that period, if you withdraw from the new account, the early withdrawal penalty applies.

To avoid an unwanted automatic rollover, mark the maturity date on your calendar and contact the bank before it arrives. You can request a withdrawal, a transfer to another account, or a rollover at a different term length. If you miss the window and the bank rolls you over, you can still withdraw during the grace period without penalty.

FDIC and NCUA insurance on fixed accounts

Fixed accounts at banks are covered by FDIC insurance up to $250,000 per depositor, per bank, per account ownership category. This means if the bank fails, the government guarantees your money up to that limit. Fixed accounts at credit unions are covered by NCUA insurance, which works the same way.

The $250,000 limit applies to each account type separately. If you have a regular savings account and a fixed account at the same bank, each is insured up to $250,000. If you have two fixed accounts at the same bank with different maturity dates, they are combined and insured together up to $250,000 total. If you have accounts at different banks, each bank's accounts are insured separately.

This insurance does not affect your interest rate or your ability to withdraw. It is straightforward a safety net that protects your principal if something goes wrong with the bank.

Where to find fixed rate accounts and how rates compare

Fixed accounts are offered by most banks and credit unions. Large national banks like Bank of America, Chase, and Wells Fargo offer them, as do smaller regional banks and online banks like Marcus, Ally, and American Express. Credit unions also offer fixed accounts, sometimes called share certificates or certificate accounts.

Rates vary significantly by bank and by the day you open the account. Online banks typically pay higher rates than brick-and-mortar banks because they have lower overhead costs. A national bank might pay 3.50% on a one-year account while an online bank pays 4.75% for the same term. Over a year on $10,000, that difference is $125.

To compare rates, visit the websites of banks you are considering, or use a rate comparison tool like Bankrate, DepositAccounts, or the FDIC's BankFind tool. These sites show current rates across many banks and let you filter by term length. Rates change frequently — sometimes daily — so the rate you see today may not be available tomorrow. If you find a rate you like, open the account promptly.

Frequently Asked Questions

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

No. Once you open a fixed account, the balance is locked. You cannot make deposits or withdrawals until the term ends. If you want to save more money during the term, you would need to open a separate regular savings account or a new fixed account.

What if I need the money before the term ends?

You can withdraw it, but you will pay an early withdrawal penalty. The penalty is usually three to six months of interest. Before you open the account, ask the bank what the penalty is so you know the cost if you need the money early.

Do I have to pay taxes on the interest I earn?

Yes. Interest earned on a fixed account is taxable income. Your 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. The interest is taxed at your ordinary income tax rate.

What is the difference between a fixed rate account and a CD?

They are the same thing. CD stands for Certificate of Deposit. Banks use the terms interchangeably — some call them fixed rate accounts, some call them CDs, some call them certificates. The product works the same way regardless of the name.

If rates go up after I open my account, can I switch to a higher rate?

Not without withdrawing and opening a new account, which triggers the early withdrawal penalty. Some banks offer a one-time rate adjustment or allow you to break the term penalty-free if rates rise significantly, but this is rare. Check your account agreement or ask the bank whether this option is available.
