How 3-Month CDs Work and What Rates Look Like Today

A 3-month certificate of deposit is a savings account where you lock your money away for exactly three months in exchange for a fixed interest rate. The bank pays you that rate no matter what happens to market rates during those 90 days. When the three months end, you get your original deposit back plus the interest earned, and you can withdraw it all or roll it into a new CD.

The rate you receive depends on which bank or credit union you choose and what the broader interest rate environment looks like that week. Rates change daily. A bank offering 4.50% one week might offer 4.75% the next, or drop to 4.25%. There is no single "the" 3-month CD rate — you have to check the institutions you're considering and compare what they're actually paying right now.

The tradeoff is simple: you give up access to your money for three months. If you need the cash before the term ends, you pay an early withdrawal penalty, which usually means losing some or all of the interest you've earned. Some banks charge a flat fee instead. Read the penalty terms before you deposit.

Key Takeaways

  • 3-month CD rates vary by bank and change daily, so you must check current rates at the specific institutions you're considering rather than relying on a single figure.
  • Your money is locked for exactly 90 days; withdrawing early triggers a penalty that typically erases most or all of the interest you've earned.
  • The interest rate is may provide and fixed for the full three months, so you know exactly what you'll earn regardless of market changes.
  • When your CD matures, you can withdraw everything or automatically roll it into a new CD at whatever rate that bank is offering at that time.

Why Banks Offer Different Rates for the Same Time Period

Banks set their own CD rates based on what they need to attract deposits and what they can earn by lending that money out. A large national bank might offer 4.00% because it has plenty of deposits already. A smaller regional bank or online bank might offer 4.80% because it needs to pull in more cash to fund loans. Neither rate is "better" in an absolute sense — they're just what each institution is willing to pay.

Online banks and credit unions often pay higher rates than brick-and-mortar banks because they have lower overhead costs. They don't maintain physical branches, so they can pass savings to depositors. A credit union might offer 4.90% while a major national bank offers 3.75% for the identical three-month term. The tradeoff is that you manage everything by phone, email, or website rather than walking into a branch.

The broader economy also matters. When the Federal Reserve raises interest rates, banks raise CD rates too because they can earn more by lending. When rates fall, CD rates fall with them. A 3-month CD that paid 5.25% in one year might pay 3.50% a year later if the Fed has cut rates.

Where to Find Current 3-Month CD Rates

The fastest way to see what's available is to visit the websites of banks and credit unions you already use or trust. Look for a "Rates" or "CDs" page. Most institutions post current rates there, updated daily or weekly. You'll see the rate, the minimum deposit required, and the early withdrawal penalty spelled out.

Comparison websites like Bankrate, DepositAccounts, and the FDIC's BankFind tool let you filter by term length and see rates from many banks at once. These sites don't sell the CDs themselves — they just show you what's available so you can compare. The rates shown are usually current within a day or two, but always confirm the rate on the bank's own website before you deposit, because rates can shift.

Credit unions often have competitive rates but may require membership. If you're not already a member, you may be able to join based on where you work, where you live, or membership in certain organizations. Ask your employer or local credit union whether you're may be able to access.

What Happens When Your 3-Month CD Matures

On day 90, your CD reaches its maturity date. The bank will notify you a few days before, usually by email or mail. At that point, you have choices: withdraw the full amount (principal plus interest), let it automatically roll into a new CD at the bank's current rate, or move the money elsewhere.

If you do nothing, most banks automatically roll your money into a new CD at the same term length — another three months — at whatever rate they're offering that day. This is called an automatic renewal. The new rate might be higher or lower than what you just earned. If you don't want to renew, you have a grace period (usually 7 to 10 days after maturity) to withdraw without penalty. After that grace period ends, you're locked in again.

Some people use maturing CDs as a trigger to reassess their savings strategy. If rates have risen significantly, you might shop around and move your money to a bank offering better terms. If rates have fallen, your current bank might still be competitive. The three-month term means you get frequent opportunities to make this choice.

Early Withdrawal Penalties and When They Apply

If you need your money before the 90 days are up, you can withdraw it, but the bank will charge a penalty. The penalty is usually stated as a number of months of interest. A common penalty is "three months of interest," which means if your CD would have earned $50 in interest, you lose $50 and get back only your original deposit. Some banks charge a flat fee instead, like $25 or $50.

A few banks offer "no-penalty CDs" where you can withdraw early without losing interest, but they pay lower rates to offset that flexibility. Whether a no-penalty CD makes sense depends on whether you think you might need the money and how much the rate difference costs you over three months.

The grace period after maturity is different from an early withdrawal. During the grace period (usually 7 to 10 days after your CD matures), you can withdraw without penalty. After the grace period closes and your CD renews, withdrawing early triggers the penalty again.

FDIC Insurance and Safety of Your Deposit

Money in a CD at an FDIC-insured bank is protected up to $250,000 per depositor, per bank, per account type. This means if the bank fails, the government guarantees you'll get your money back up to that limit. Most people's CDs are well under $250,000, so they're fully covered.

Credit unions use a similar system called NCUA insurance, which also covers up to $250,000. If you have multiple CDs at the same bank, they're added together for insurance purposes. If you have $150,000 in one CD and $120,000 in another at the same bank, only $250,000 total is insured, and you'd lose $20,000 if the bank failed.

The insurance applies regardless of what the CD rate is or how long the term is. A 3-month CD is just as protected as a 5-year CD. The rate has no bearing on safety.

Frequently Asked Questions

Can I add money to a CD before it matures?

No. A CD is a fixed contract — you deposit a lump sum and leave it untouched for the full term. You cannot add money mid-term. If you want to deposit more, you have to open a separate CD or wait until your current one matures and roll the proceeds into a new CD.

What's the minimum amount I need to open a 3-month CD?

Minimums vary by bank. Some require as little as $500; others require $1,000, $2,500, or more. Online banks often have lower minimums than traditional banks. Check the specific bank's website for their requirement.

Is a 3-month CD better than a savings account?

CDs usually pay higher rates than savings accounts at the same bank because you're giving up access to your money. If you won't need the cash for three months, a CD typically earns more. If you might need it sooner, a savings account's flexibility is worth the lower rate.

Do I have to pay taxes on CD interest?

Yes. CD interest is taxable income. 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. The interest is taxed as ordinary income at your regular tax rate.

What if rates drop right after I lock in my CD?

You're protected. Your rate is fixed for the full three months, so if rates fall the next day, you still earn the rate you locked in. This is the main benefit of a CD — certainty. The downside is that if rates rise, you're stuck with your original rate until maturity.
