A CD and a savings account are different products with different rules
A certificate of deposit is not a savings account. Both hold money at a bank or credit union, but they work in opposite ways. A savings account lets you deposit and withdraw whenever you want. A CD locks your money away for a set period — three months, one year, five years — in exchange for a higher interest rate. If you withdraw before that period ends, you pay a penalty.
The key difference is control. With a savings account, the money is yours to use. With a CD, you are agreeing not to touch it. The bank rewards that agreement by paying you more interest than a savings account would. That trade-off — higher interest in exchange for locked-in time — is what makes a CD a CD.
Key Takeaways
- A CD requires you to leave money untouched for a fixed period; a savings account lets you withdraw anytime without penalty.
- CDs pay higher interest rates than savings accounts because the bank knows your money will stay put for the full term.
- Breaking a CD early costs you money through an early withdrawal penalty, which can eat into or eliminate your interest earnings.
- A savings account is better if you need the money within a year or might need it unexpectedly; a CD is better if you can commit to leaving it alone.
Why banks pay more for a CD than a savings account
Interest rates on CDs are higher because the bank can count on having your money for the entire term. When you open a savings account, the bank knows you might pull out $500 tomorrow or $5,000 next month. That unpredictability costs the bank money — it has to keep more cash on hand and cannot lend out as much.
With a CD, the bank knows exactly when your money will be returned. It can lend that money out for the full term and plan around it. In return, it pays you a higher rate. Right now, a savings account might pay 4% to 5% annual interest, while a one-year CD might pay 5% to 5.5%. That gap widens for longer terms — a five-year CD might pay 4.5% to 5%, depending on the bank and market conditions.
The longer you lock money away, the higher the rate usually is — though not always. Sometimes a one-year CD pays more than a three-year CD. The rate depends on what the bank thinks interest rates will do over time, not on how long you personally are willing to wait.
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 a certain number of months of interest. A one-year CD might have a three-month penalty, meaning you lose three months' worth of the interest you earned. A five-year CD might have a one-year penalty.
The penalty can be steep enough to wipe out all your interest and eat into your original deposit. If you put $10,000 into a one-year CD at 5% interest and withdraw after six months, you might earn $250 in interest — but the three-month penalty could be $125, leaving you with only $125 in gain. In a worst-case scenario, if you withdraw very early from a long-term CD, you could lose money overall.
This is why a CD only makes sense if you genuinely will not need the money. If there is any chance you might need it, a savings account is safer, even at a lower interest rate.
When a CD makes sense and when a savings account does
Choose a CD if you have money you will not need for a specific period and you want to earn more interest. Common reasons include saving for a down payment you plan to make in two years, setting aside money for a known expense three years from now, or parking cash you straightforward do not want to touch. The locked-in rate also protects you if interest rates fall — your rate stays the same for the full term.
Choose a savings account if you might need the money within a year, if you are building an emergency fund, or if you are not sure when you will need it. A savings account also makes sense if you are still deciding how much to save or if you are adding to your savings regularly. You can deposit and withdraw without penalty, and your money stays accessible.
Some people use both. They might keep three to six months of expenses in a savings account for emergencies and put longer-term savings into CDs. This approach gives them flexibility where they need it and a higher return on money they can afford to lock away.
How CD interest rates compare across different terms
Banks offer CDs in many lengths: 3 months, 6 months, 1 year, 2 years, 3 years, 5 years, and sometimes longer. The rate you get depends on the term you choose and current market conditions. Generally, longer terms pay higher rates, but this is not a rule — sometimes a one-year CD pays more than a two-year CD.
The yield curve — the relationship between short-term and long-term interest rates — changes constantly. When the curve is steep, longer CDs pay much more. When it is flat or inverted, the difference is small or even reversed. This means you cannot assume a five-year CD will always pay more than a one-year CD. You have to check the rates your bank is offering right now.
If you are unsure which term to choose, a one-year CD is a reasonable middle ground. It locks in a decent rate without committing you to years of illiquidity. You can also use a CD ladder — buying multiple CDs with different maturity dates so that one matures every few months, giving you regular access to some of your money.
The difference between a CD and a money market account
A money market account is a third option that sits between a savings account and a CD. It usually pays more interest than a savings account but less than a CD. The catch is that it often requires a higher minimum balance and may limit how many withdrawals you can make per month.
Unlike a CD, a money market account has no maturity date and no early withdrawal penalty. You can withdraw whenever you want, but the bank may restrict you to a certain number of withdrawals per statement cycle. Interest rates on money market accounts are variable, meaning they change as market conditions change — unlike a CD, where your rate is locked in.
If you want higher interest than a savings account but need more flexibility than a CD offers, a money market account might work. But check the withdrawal limits and minimum balance requirements before opening one.
Frequently Asked Questions
Can I move money from a savings account to a CD without losing interest?
Yes. Moving money from one account to another is not a taxable event and does not trigger penalties. You straightforward withdraw from the savings account and deposit into the CD. You will not earn interest on the money while it is in transit, but that is usually just a day or two. Any interest you earned in the savings account stays with you.
What if interest rates go up after I buy a CD?
You are locked into your original rate for the full term. If rates rise, you will earn less than you could have earned with a new CD. This is the trade-off of locking in a rate — you are protected if rates fall, but you miss out if they rise. Some banks offer a one-time rate adjustment or allow you to bump up your rate, but this is rare and usually only for new customers.
Do I have to pay taxes on CD interest?
Yes. Interest earned on a CD is taxable income in the year you earn it, even if you do not withdraw the money. Your bank will send you a 1099-INT form at tax time showing how much interest you earned. This is one reason CDs in retirement accounts like IRAs are useful — the interest grows tax-deferred.
Can I open a CD if I do not have much money?
Most banks have minimum deposit requirements for CDs, often $500 to $2,500, though some online banks have minimums as low as $100 or even $1. Credit unions sometimes have lower minimums than banks. Check with your bank or credit union to see what they require.
What happens when my CD matures?
When the term ends, your CD matures. The bank will either automatically renew it for another term at the current rate, or deposit the money into a linked savings account. You usually have a grace period — often 7 to 10 days — to decide what to do before the renewal happens. Read your CD agreement to see what your bank does by default.
