A CD pays more interest, but locks your money away. A savings account keeps your money accessible.
A certificate of deposit (CD) typically offers a higher interest rate than a regular savings account, sometimes two to five times higher depending on the bank and how long you commit your money. The trade-off is that you agree to leave the money untouched for a set period—usually three months to five years. If you withdraw before that date ends, the bank charges a penalty, which is a fee that reduces your earnings or principal.
A savings account lets you deposit and withdraw money whenever you want, with no penalty. The interest rate is lower, but your money stays available for emergencies or unexpected expenses. Which one makes sense depends on whether you have money you won't need for a while and whether you can tolerate the penalty if circumstances change.
Key Takeaways
- CDs pay higher interest rates than savings accounts, but require you to lock money away for a fixed term ranging from three months to five years.
- Early withdrawal from a CD triggers a penalty that typically costs several months of interest, making it expensive to access your money before the term ends.
- Savings accounts offer lower rates but complete flexibility—you can withdraw at any time without penalty.
- The interest rate difference between a CD and a savings account varies by bank and economic conditions, so comparing rates at your specific institution matters.
How CD interest rates compare to savings account rates
Right now, savings accounts at most large banks pay between 0.01% and 0.05% annual interest. Online banks and credit unions often pay higher rates—sometimes 4% to 5% or more—but these vary constantly based on what the Federal Reserve does with interest rates. CDs at the same institutions typically pay 0.5% to 2% more than their savings account rate for the same term.
The longer you lock money into a CD, the higher the rate usually is. A three-month CD might pay 4.5%, while a five-year CD at the same bank might pay 5.2%. This is because the bank wants to keep your money longer and can lend it out for a longer period. Savings accounts have no term, so they pay whatever the bank decides, and that rate can change at any time.
The actual difference in dollars depends on how much you deposit. If you put $10,000 in a savings account paying 4% for one year, you earn $400. The same $10,000 in a CD paying 5% earns $500—a $100 difference. Over five years, that gap grows much larger.
Early withdrawal penalties and what they cost
Every CD has an early withdrawal penalty written in the contract before you open it. The penalty is usually stated as a number of months of interest. A common penalty is three months of interest, which means if you withdraw early, the bank subtracts three months' worth of what you would have earned and takes that from your principal or your interest.
On a $10,000 CD paying 5% annually with a three-month penalty, you earn about $125 every three months. If you withdraw after six months, the bank takes back $125 (three months of interest) as the penalty. You keep your $10,000 plus $125 in interest, but you lose the $125 penalty. Some banks have harsher penalties—six months or even a year of interest—especially on longer-term CDs.
The penalty can also eat into your principal if you withdraw very early. If you withdraw after one month on a CD with a three-month penalty, the bank may subtract $312.50 (three months of interest) from your $10,000, leaving you with $9,687.50. This is why CDs only make sense if you genuinely do not need the money before the term ends.
When a CD makes sense for your money
A CD works well if you have money sitting in a savings account that you know you will not need for at least six months to a year. Examples include a bonus you received, a tax refund, or money you are saving for a specific purchase you know is coming in two years. The higher interest rate means your money grows faster than it would in a savings account, and the penalty does not matter because you were not planning to touch it anyway.
CDs also work if you want to remove the temptation to spend money. Some people find it psychologically easier to save when the money is locked away and withdrawal costs money. If you have a history of dipping into savings for non-emergencies, a CD creates a real barrier.
CDs are less useful if you have irregular income, unstable employment, or ongoing medical expenses. If there is any real chance you might need the money before the term ends, the penalty will likely wipe out the interest gain and cost you principal too.
Building a ladder with multiple CDs
Some people use a strategy called CD laddering to get higher rates while keeping some money accessible each year. Instead of putting all your money into one five-year CD, you split it into five one-year CDs. Each year, one CD matures and you can withdraw the money or roll it into a new CD at whatever the current rate is.
For example, if you have $50,000, you could open five $10,000 CDs with terms of one, two, three, four, and five years. After one year, the first CD matures and you can access that $10,000 without penalty. You can then open a new five-year CD with it at the current rate. This approach gives you some of the higher rates of long-term CDs while keeping money accessible on a regular schedule.
Laddering works best if you have a large amount to invest and you are comfortable managing multiple accounts. It also requires that you actually let the CDs mature instead of withdrawing early, or the penalty defeats the purpose.
What happens when your CD reaches maturity
When the CD term ends, the bank sends you a notice—usually 10 to 14 days before the maturity date. At that point, you have a few options. You can withdraw the money and the interest you earned, with no penalty. You can move the money to a savings account. Or you can renew the CD, which means the bank automatically opens a new CD for the same term at whatever the current rate is.
Most banks automatically renew CDs unless you tell them not to. This means if you forget to act, your money stays locked up for another term. Read the maturity notice carefully and contact your bank if you want to do something different—withdraw, move to savings, or switch to a different term length.
If rates have dropped since you opened your CD, you might not want to renew at the new rate. If rates have risen, renewing locks in a better rate. Either way, you have the choice when the term ends, and there is no penalty for whatever you decide to do.
Frequently Asked Questions
Can I withdraw money from a CD before it matures without a penalty?
No. Every CD has an early withdrawal penalty written into the contract. The penalty is usually several months of interest, and it comes out of your principal or earnings. Some banks offer no-penalty CDs that let you withdraw early, but they pay lower interest rates to compensate.
What is the difference between a CD and a money market account?
A money market account is a hybrid: it pays higher interest than a savings account but lower than a CD, and it lets you withdraw money without penalty. However, it usually requires a higher minimum balance and limits how many withdrawals you can make per month. CDs have no withdrawal limit—you just pay a penalty if you withdraw early.
Should I put my emergency fund in a CD?
No. Emergency funds need to stay in a regular savings account where you can access them instantly without penalty. CDs are for money you know you will not need for months or years. If you use a CD for emergency money and have to withdraw early, the penalty will reduce the amount you actually have available when you need it.
Do I pay taxes on CD interest?
Yes. CD interest is taxable income in the year you earn it, even if you do not withdraw the money. The bank sends you a 1099-INT form at tax time showing how much interest you earned. This is one reason CDs in regular taxable accounts make more sense for longer-term money—the higher rate compensates for the tax you owe.
What happens if the bank fails while my money is in a CD?
The FDIC (Federal Deposit Insurance Corporation) protects CDs up to $250,000 per depositor per bank. If the bank fails, the FDIC pays you your principal plus all earned interest, even if the CD has not matured yet. This protection applies to most banks, but verify your bank is FDIC-insured before opening a CD.
