A CD makes sense if you won't need the money for months and want a may provide rate higher than your savings account offers
A certificate of deposit (CD) is a savings product where you give a bank or credit union a lump sum of money for a fixed period—typically three months to five years—in exchange for a higher interest rate than a regular savings account. You cannot withdraw the money before the term ends without paying a penalty, usually a few months' worth of interest.
Whether a CD is worth it depends on three things: whether you have money you won't touch, whether the CD rate is meaningfully higher than your savings account rate, and whether you can afford the penalty if an emergency forces an early withdrawal. If all three line up, a CD will earn you more money. If any one is shaky, a regular savings account is safer.
Key Takeaways
- CDs pay a fixed interest rate for a set term, while savings accounts let you withdraw anytime but usually pay less interest.
- The penalty for early withdrawal from a CD typically costs several months of interest, so only lock money away if you are certain you won't need it.
- CD rates change with the broader interest rate environment, so the rate you see today may be higher or lower than what you see in three months.
- A high-yield savings account with no withdrawal restrictions may pay nearly as much as a CD while keeping your money accessible.
How CD rates compare to savings account rates right now
CD rates vary by bank, by term length, and by the current economic environment. A one-year CD at one bank might pay 4.5 percent, while a one-year CD at another pays 3.8 percent. A high-yield savings account at a third bank might pay 4.3 percent with no lock-in period at all.
The difference between a CD and a savings account at the same bank is usually between 0.5 and 1.5 percentage points, depending on the term. Longer terms (like five years) sometimes pay more, but not always—sometimes a one-year CD pays as much or more than a five-year CD. Check the specific rates your bank or credit union is offering before you decide.
The broader point: if a savings account at your current bank pays 0.01 percent and a CD pays 4.5 percent, the CD is clearly better for money you won't touch. If a high-yield savings account pays 4.3 percent and a CD pays 4.5 percent, the difference is small enough that the flexibility of the savings account might be worth more to you.
What happens if you need the money before the CD matures
Most CDs charge an early withdrawal penalty if you take your money out before the term ends. The penalty is usually expressed as a number of months of interest. A one-year CD with a three-month penalty means you lose three months' worth of the interest you earned. On a $10,000 CD paying 4.5 percent annually, that is roughly $112 in lost interest.
Some banks advertise "no-penalty CDs" that let you withdraw early without losing interest, but these almost always pay a lower rate than regular CDs—sometimes only slightly higher than a savings account. The tradeoff is built in: you get flexibility or you get a higher rate, rarely both.
Before opening a CD, read the fine print about the penalty. If you think there is even a moderate chance you will need the money—for a car repair, medical bill, or job loss—a regular savings account is the safer choice, even if it pays less.
The math: how much extra money you actually earn
The difference between a CD and a savings account sounds small in percentage terms, but it adds up over time. Here is what $5,000 earns over one year at different rates:
| Rate | Interest earned in one year |
|---|---|
| 0.01% (typical savings account) | $0.50 |
| 4.0% (typical CD) | $200 |
| 4.5% (higher-rate CD) | $225 |
On $5,000, the difference between a 0.01 percent savings account and a 4.5 percent CD is $224.50 over a year. On $20,000, it is $898. On $50,000, it is $2,245. The larger your balance and the longer your term, the more the higher rate matters.
But subtract the penalty if you withdraw early. If you put $5,000 in a one-year CD at 4.5 percent and need it after six months, you lose roughly $112 in interest. You still come out ahead compared to a 0.01 percent savings account, but the advantage shrinks.
When a high-yield savings account is a better choice
A high-yield savings account is a regular savings account that pays a much higher interest rate than the standard 0.01 percent. Many online banks and credit unions offer high-yield savings accounts that pay 4.0 to 4.5 percent, sometimes as much as a CD, with no lock-in period and no penalty for withdrawal.
If a high-yield savings account at your bank pays 4.4 percent and a one-year CD pays 4.6 percent, the CD earns you an extra $10 per year on $5,000. That is not worth locking your money away for a year if you might need it. But if the CD pays 5.0 percent and the savings account pays 4.0 percent, the CD's extra $50 per year might be worth the restriction.
High-yield savings accounts are usually found at online banks or credit unions, not at traditional brick-and-mortar banks. If your current bank's savings account pays very little, shopping around for a high-yield option might give you most of the CD's benefit without the lock-in.
CD laddering: a way to get higher rates and keep some money accessible
If you have a larger amount of money and want both a higher rate and some flexibility, you can split it into multiple CDs with different maturity dates. This is called CD laddering.
For example, if you have $10,000, you might put $2,000 in a one-year CD, $2,000 in a two-year CD, $2,000 in a three-year CD, $2,000 in a four-year CD, and $2,000 in a five-year CD. Each year, one CD matures and you can withdraw the money, reinvest it in a new five-year CD, or move it to a savings account. You get the higher rates of longer-term CDs while having access to some money every year.
Laddering works best if you have at least $5,000 to $10,000 to divide. If you have less, the benefit is small and the effort is not worth it. Also, laddering only helps if longer-term CDs pay noticeably more than shorter-term ones—check your bank's rates before you set it up.
What to know about CD rates in a changing interest rate environment
Interest rates set by the Federal Reserve affect what banks offer on CDs and savings accounts. When the Fed raises rates, new CDs pay more. When the Fed lowers rates, new CDs pay less. But your existing CD's rate is locked in—it does not change, even if rates drop.
This cuts both ways. If you lock in a 4.5 percent CD and rates fall to 3.0 percent, you are glad you locked in. If you lock in a 4.5 percent CD and rates rise to 5.5 percent, you are stuck with 4.5 percent. You cannot predict which way rates will move, so do not try. Lock in a CD only if the current rate feels fair to you right now, not because you think rates will fall.
Before opening a CD, check what rate your bank is offering and compare it to at least two other banks. Rates vary enough that shopping around can earn you an extra 0.3 to 0.5 percentage points, which adds up over time.
Frequently Asked Questions
Can I move money from a CD to a savings account without a penalty?
No. A CD is a contract—you agree to leave the money there for the full term. Withdrawing early triggers the penalty, whether you move it to a savings account at the same bank or somewhere else. The only exception is a no-penalty CD, which lets you withdraw anytime but pays a lower rate.
What if interest rates drop after I open a CD?
Your CD's rate stays the same for the full term. You locked in the rate when you opened it, so a drop in rates does not affect you. You can simply let the CD mature and decide whether to open a new one at the lower rate or move the money elsewhere.
Is a CD FDIC insured?
Yes, CDs at banks are covered by FDIC insurance up to $250,000 per depositor per bank. CDs at credit unions are covered by NCUA insurance up to the same limit. This means if the bank or credit union fails, your money is protected. Check that your bank or credit union has this insurance before you open a CD.
Should I open a CD if I have an emergency fund?
Only if the money in the CD is separate from your emergency fund. Your emergency fund should stay in a regular savings account where you can access it instantly. A CD is for money you know you will not need for several months or longer.
Do I have to open a CD at my current bank?
No. You can open a CD at any bank or credit union. Online banks often offer higher CD rates than traditional banks, so it is worth comparing rates across several institutions before you decide where to put your money.
