A fixed term savings account locks your money away for a set period in exchange for a may provide interest rate
A fixed term savings account — also called a certificate of deposit (CD) in the United States — is a savings product where you deposit a lump sum of money and agree not to touch it until a specific date. In return, the bank or credit union pays you a fixed interest rate that does not change, no matter what happens to market rates during that time.
The trade-off is straightforward: you give up access to your money, and the lender gives you certainty about how much interest you will earn. If you withdraw before the term ends, you pay a penalty — usually a portion of the interest you would have earned, though some accounts charge a flat fee or a percentage of the principal.
Fixed term accounts come in lengths ranging from a few months to five years or longer, depending on the institution. The longer the term, the higher the interest rate typically is, because the bank has your money locked in for a longer period and can lend it out with more confidence.
Key Takeaways
- Your money is locked away for a fixed period — typically three months to five years — and you cannot withdraw it without paying a penalty.
- The interest rate is set when you open the account and does not change, even if market rates rise or fall during the term.
- Longer terms usually pay higher interest rates because the bank keeps your money for a longer time.
- Early withdrawal penalties vary by institution and can eat up most or all of your earned interest.
- Fixed term accounts are insured by the FDIC (up to $250,000 per account at banks) or NCUA (at credit unions), so your principal is protected even if the institution fails.
How the interest rate and term length work together
When you open a fixed term account, you choose both the amount you deposit and the length of time you want to lock it away. The bank then quotes you an interest rate for that specific term. A three-month CD might pay 4.5 percent, while a five-year CD from the same bank might pay 5.2 percent. The rate you receive is locked in on the day you open the account.
Interest is usually compounded daily or monthly and added to your account automatically. At the end of the term — called the maturity date — you receive your original deposit plus all the interest earned. Some accounts let you choose whether to withdraw the money or roll it into a new fixed term account at whatever rate is current at that time.
The relationship between term length and rate is not random. Banks use longer-term CDs to fund longer-term loans, so they can afford to pay more interest. If you lock money away for five years, the bank knows it can lend that money out for five years and collect interest on it. If you only lock it away for three months, the bank has more uncertainty about what it can do with the money next.
Early withdrawal penalties and when they apply
If you need your money before the maturity date, you can withdraw it — but the bank will charge you a penalty. The penalty structure varies widely. Some banks charge a flat fee (for example, $25). Others charge a percentage of your balance or a number of months' worth of interest.
A common penalty is three to six months of interest. If you have a $10,000 CD earning 5 percent annually and you withdraw after six months, the bank might charge you six months of interest (about $250) as the penalty. You would receive your $10,000 plus the six months of interest you actually earned ($250), minus the penalty ($250), leaving you with $10,000 — no gain and no loss, but also no benefit for locking the money away.
Some institutions have no-penalty CDs, which let you withdraw without a fee, but these almost always pay lower interest rates than standard fixed term accounts. The lower rate is the trade-off for keeping your options open.
Fixed term accounts versus regular savings accounts
A regular savings account lets you deposit and withdraw money whenever you want, with no penalty. The interest rate is usually variable, meaning the bank can change it at any time. In exchange for that flexibility, savings accounts typically pay much lower interest — often 0.01 percent to 0.5 percent, depending on the bank and current market conditions.
A fixed term account pays significantly more interest — currently 4 percent to 5.5 percent depending on the term and the institution — but you cannot touch the money without a penalty. The choice between them depends on whether you need access to the money or whether you can afford to lock it away.
If you have money you know you will not need for the next two years, a fixed term account will earn you substantially more. If you might need the money in an emergency, a regular savings account is safer, even though it pays less.
How FDIC and NCUA insurance protects your money
Fixed term accounts at banks are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor, per bank. This means if the bank fails, the FDIC will pay you back your principal and any interest earned up to the maturity date, even if the bank no longer exists.
At credit unions, the same protection comes from the National Credit Union Administration (NCUA), also up to $250,000 per account. This insurance covers the full amount you deposited plus all interest earned, as long as the total does not exceed $250,000.
The insurance does not cover losses from early withdrawal penalties or from market changes. It only protects you if the institution itself fails. In practice, bank and credit union failures are rare, and when they happen, depositors are made whole through this insurance.
When a fixed term account makes sense for your situation
A fixed term account is most useful when you have a specific amount of money you will not need for a known period of time. Examples include money you are saving for a down payment two years from now, a lump sum from a bonus or inheritance that you want to grow safely, or an emergency fund that is already larger than you need for immediate expenses.
Fixed term accounts are less useful if you might need the money sooner, if you want to add to your savings regularly (most CDs do not let you make additional deposits after opening), or if you think interest rates will rise significantly and you want to take advantage of higher rates later.
Some people use a CD ladder strategy: they open multiple CDs with different maturity dates (for example, one-year, two-year, and three-year terms). As each one matures, they can decide whether to roll it into a new CD at the current rate or withdraw the money. This approach gives you some flexibility while still locking away most of your money for higher interest.
How to compare fixed term accounts across banks and credit unions
The interest rate is the most obvious thing to compare, but it is not the only one. You should also look at the term lengths available, the early withdrawal penalty structure, whether the account allows additional deposits, and what happens at maturity (does it automatically roll over, or do you have to take action?).
Online banks and credit unions typically offer higher rates than brick-and-mortar banks because they have lower overhead costs. Rates change frequently — sometimes daily — so a rate that is highest today may not be highest next week. Websites like Bankrate, DepositAccounts, and the FDIC's own BankFind tool let you compare rates across institutions.
Before you open an account, read the disclosure document carefully. It will spell out the exact penalty you will pay for early withdrawal, what the maturity date is, and whether interest is compounded daily or monthly. These details matter when you are comparing two accounts with similar rates.
Frequently Asked Questions
Can I add money to a fixed term account after I open it?
Most fixed term accounts do not allow additional deposits after the initial opening. You deposit a lump sum, and that amount stays locked in until maturity. If you want to add more money, you would need to open a separate account. Some credit unions offer share certificates that allow additional deposits, so ask your institution if that option is available.
What happens to my money when the fixed term ends?
When the maturity date arrives, the bank will either automatically roll your money into a new fixed term account at the current rate, or it will move the funds to a regular savings account. Check your account documents to see what your bank does by default. Most banks give you a grace period (usually 7 to 10 days) to decide what to do before the automatic action happens.
Is the interest I earn on a fixed term account taxable?
Yes. The interest you earn is considered income and is taxable in the year it is credited to your account, 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 true whether the account is at a bank or credit union.
What if interest rates rise after I open my fixed term account?
Your rate stays the same for the entire term — that is the whole point of a fixed term account. If rates rise, you are locked in at the lower rate. When your account matures, you can open a new one at the higher rate if you want. This is why some people use CD ladders: they can take advantage of higher rates as each CD matures without having all their money locked in at an old, lower rate.
Can I use a fixed term account as an emergency fund?
Not a good one. The whole purpose of an emergency fund is to have money you can access immediately without penalty. A fixed term account charges you to withdraw early, which defeats that purpose. Keep your emergency fund in a regular savings account or money market account, and use fixed term accounts for money you genuinely will not need for several months or years.
