CDs are savings accounts with a fixed term and a locked interest rate

A certificate of deposit is a savings account where you agree to leave your money untouched for a set period—three months, one year, five years, whatever you choose. In exchange, the bank pays you a higher interest rate than it would on a regular savings account. The catch is that if you withdraw the money before the term ends, you pay a penalty, usually a few months' worth of interest.

A regular savings account has no term. You can deposit and withdraw whenever you want, with no penalty. The trade-off is that the interest rate stays lower—often much lower. Banks offer this flexibility because they cannot count on having your money for any particular length of time.

The core difference comes down to predictability. When you buy a CD, both you and the bank know exactly how long the money will sit there. The bank can lend that money out with confidence, so it pays you more. With a savings account, the bank has to keep more cash on hand in case you need it tomorrow, so it pays you less.

Key Takeaways

  • CDs lock your money for a fixed term in exchange for a higher interest rate; savings accounts let you withdraw anytime but pay lower rates.
  • Breaking a CD early means paying a penalty, usually several months of the interest you earned, which can wipe out your gains.
  • Both CDs and savings accounts are FDIC-insured up to $250,000 per account holder per bank, so your principal is protected either way.
  • A CD makes sense if you know you will not need the money for a specific period; a savings account works better if you need access to funds regularly.
  • Interest rates on both products change with the Federal Reserve's rate decisions, so the gap between CD and savings rates shifts over time.

How the interest rates compare in practice

A typical savings account at a large bank pays around 0.01% annual interest. A one-year CD at the same bank might pay 4.5% to 5.0%. That difference matters. On $10,000, the savings account earns roughly $1 per year. The CD earns $450 to $500.

Online banks and credit unions often pay more than large national banks on both products. You might find a savings account paying 4.0% to 4.5% and a one-year CD paying 5.0% to 5.5%. The longer the CD term, the higher the rate usually goes—a five-year CD might pay 5.25% or more.

These rates change constantly based on what the Federal Reserve does with its benchmark interest rate. When the Fed raises rates, banks raise CD and savings rates within weeks. When the Fed cuts rates, banks cut them too, though sometimes more slowly on savings accounts.

What happens if you need the money before the CD matures

If you withdraw from a CD before the term ends, you pay an early withdrawal penalty. The penalty is usually expressed as a number of months of interest. A common penalty on a one-year CD is three months of interest. On a five-year CD, it might be six months or a year.

Here is what that means in dollars. Say you have a $10,000 one-year CD paying 5% annual interest. You earn about $500 over the year. If you withdraw after six months, you get your $10,000 back, but you lose three months of interest—roughly $125. You walk away with $10,000 and $125 in earned interest, instead of the full $250 you would have earned by the end of the year.

In some cases, the penalty can exceed the interest you earned, especially if you withdraw very early. A $10,000 CD paying 5% that you close after one month might cost you $125 in penalties but you have only earned about $42 in interest. You would owe the bank $83 out of pocket.

This is why CDs only make sense if you genuinely will not need the money. If there is any chance you might need it, a savings account is safer.

FDIC insurance protects both equally

Both CDs and savings accounts at FDIC-insured banks are protected up to $250,000 per depositor per bank. If the bank fails, the FDIC covers your balance dollar for dollar, up to that limit. This protection applies whether your money is in a CD or a savings account.

The insurance covers the principal you deposited plus any interest earned up to the moment the bank failed. It does not cover interest you would have earned if the bank had stayed open.

If you have more than $250,000 to save, you can open accounts at multiple banks to stay within the insurance limit at each one. Some people open CDs at several different banks specifically to keep each account under the $250,000 threshold.

When a CD makes sense and when it does not

A CD is the right choice if you have money you will not need for a known period. Examples: you are saving for a down payment on a house in two years, you want to set aside money for a child's college fund in ten years, or you received a bonus and want to lock in current high rates before they drop.

A savings account is better if you need to keep money accessible. Examples: an emergency fund you might need to tap in a month, money you are saving for a vacation next summer, or a buffer account you use to cover unexpected expenses.

Some people use both. They keep three to six months of expenses in a high-yield savings account for emergencies, and put longer-term savings into CDs to earn more.

The ladder strategy: spreading CDs across different terms

One way to get higher CD rates while keeping some money accessible is called CD laddering. You buy multiple CDs with different maturity dates. For example, you might buy five one-year CDs, one maturing each year for the next five years. Each year, one CD matures and you can either withdraw the money or roll it into a new five-year CD.

This approach gives you access to some of your money every year while keeping most of it locked in at higher rates. It also protects you if rates drop—you are not putting all your money into CDs at once, so you spread your purchases across different rate environments.

Laddering requires discipline and planning, but it is a common strategy for people who want higher returns without completely locking away their savings.

Frequently Asked Questions

Can I move money from a savings account to a CD without losing anything?

Yes. Moving money from a savings account to a CD is a normal transfer with no penalty. You are straightforward taking funds you already have and putting them into a CD. The only cost is the opportunity cost—you lose the flexibility of the savings account.

What if interest rates drop after I buy a CD?

You are locked in at the rate you agreed to when you bought the CD. If rates drop, your CD still pays the original higher rate for the full term. This is one reason CDs are attractive when rates are high—you lock in that rate before it falls.

Do I have to pay taxes on CD interest?

Yes. CD interest is taxable income in the year you earn it, just like savings account interest. The bank will send you a 1099-INT form at tax time showing how much interest you earned. You report this on your tax return.

Can I add money to a CD after I open it?

No. CDs are fixed-amount accounts. You deposit a lump sum when you open it, and that amount stays the same until maturity. If you want to save more, you open a separate CD or use a savings account.

What happens when a CD matures?

When the term ends, the bank notifies you that the CD has matured. You then have a window—usually 7 to 10 days—to decide what to do. You can withdraw the money, roll it into a new CD at the current rate, or move it to a savings account. If you do nothing, many banks automatically roll it into a new CD at the current rate.
