What a CD rate is and why it matters

A CD rate is the percentage of interest a bank pays you for letting them hold your money in a certificate of deposit for a set period of time. When you open a CD, you agree to leave your money untouched until a specific date—called the maturity date—and in exchange, the bank locks in a rate and pays you that interest.

The rate matters because it determines how much extra money you'll have when your CD matures. A CD paying 4.5% for one year will give you more than a CD paying 2.0% for the same year, assuming you deposit the same amount. The difference compounds—meaning you earn interest on your interest—so even small rate differences add up over time.

CD rates change constantly because they follow the broader interest rate environment set by the Federal Reserve. When the Fed raises its benchmark rate, banks typically raise CD rates to attract deposits. When the Fed lowers rates, CD rates fall too. This is why a CD opened today might pay a different rate than one opened three months ago.

Key Takeaways

  • A CD rate is the annual percentage you earn on money locked in a CD until its maturity date, and it's fixed when you open the account.
  • CD rates vary by bank, by the length of time you commit to (the term), and by how much money you deposit.
  • Longer-term CDs usually pay higher rates than shorter-term ones, but you cannot access your money without penalty until the term ends.
  • You can compare rates across banks to find the highest rate available for the term length you want.
  • If you withdraw money before the maturity date, the bank charges an early withdrawal penalty that reduces your earnings or principal.

How CD rates differ by term length

The length of time you commit to keeping money in a CD—called the term—is the biggest factor in what rate you'll receive. Banks typically offer CDs with terms ranging from three months to five years, though some offer longer terms.

In most market conditions, longer terms pay higher rates. A one-year CD might pay 4.0%, while a five-year CD from the same bank might pay 4.75%. The bank pays more for the longer commitment because they want to lock in your money for a longer period and because inflation risk is higher over five years than over one year.

Shorter-term CDs—three months, six months, one year—let you move your money more frequently and respond to rate changes. If rates rise, you can let a short-term CD mature and open a new one at the higher rate. With a five-year CD, you're stuck at the original rate unless you pay the early withdrawal penalty.

Why rates vary between banks

Two banks offering the same CD term can pay different rates. This happens because banks set their own rates based on how much money they need to attract and what they plan to do with deposits.

Large national banks often pay lower CD rates than smaller regional banks or online-only banks. National banks have many ways to attract deposits—branch locations, brand recognition, checking account bundles—so they don't need to pay as much on CDs. Online banks have lower overhead costs and fewer ways to attract customers, so they often pay higher CD rates to compete.

The amount you deposit can also affect the rate. Some banks offer higher rates on larger deposits—say, $25,000 or more—or lower rates on smaller deposits. A few banks offer tiered rates where the rate increases as your balance grows. Always check whether the rate you see applies to your deposit amount.

How to read and compare CD rates

When you look at a CD rate, you'll see it listed as an APY, which stands for Annual Percentage Yield. This is the total return you'll earn in one year, including the effect of compounding. APY is the standard way banks display rates, so you can compare one CD to another fairly.

To compare rates across banks, line up CDs with the same term length. A 4.5% APY on a one-year CD from Bank A is directly comparable to a 4.3% APY on a one-year CD from Bank B. The difference—0.2%—might seem small, but on a $10,000 deposit, it's $20 in extra earnings over the year.

When comparing, also check the minimum deposit required and whether there are any special conditions. Some banks offer promotional rates for new customers or for opening a CD through their website. These rates are real, but they may drop after a set period or apply only to first-time CD buyers.

What happens to your rate if you withdraw early

The rate you lock in is may provide for the full term—but only if you leave your money in the CD until maturity. If you need to withdraw money before the maturity date, the bank charges an early withdrawal penalty.

The penalty amount varies by bank and by term length. A three-month CD might have a penalty equal to one month of interest. A five-year CD might have a penalty equal to six months of interest or more. The penalty is deducted from your earnings first; if the penalty is larger than your earnings, it comes out of your principal.

For example: You open a $10,000 one-year CD at 4.5% APY. After six months, you need the money and withdraw it. You've earned about $225 in interest so far. If the early withdrawal penalty is $300, you receive $9,925—your original $10,000 minus the $75 difference between your earnings and the penalty.

How CD rates fit into your savings plan

CD rates are higher than savings account rates, but they come with a tradeoff: your money is locked away. If you have money you won't need for a specific period—six months, two years, five years—a CD at the current rate can be a straightforward way to earn more than a regular savings account.

Some people use a CD ladder to balance rate and flexibility. Instead of putting all your money in one five-year CD, you open multiple CDs with different maturity dates—one maturing in one year, one in two years, one in three years, and so on. As each CD matures, you can open a new one at whatever the current rate is. This way, you're not locked into one rate for five years, but you're still earning more than a savings account.

Before opening a CD, make sure the money you're depositing is money you won't need before the maturity date. CDs are designed for money you're setting aside, not for emergency funds or money you might need soon.

Frequently Asked Questions

Can a CD rate change after I open the account?

No. Once you open a CD, your rate is locked in for the entire term. Even if the bank raises or lowers its rates the next day, your rate stays the same until the CD matures. This is the main advantage of a CD—you know exactly what you'll earn.

Is the rate I see online the same rate I'll get in a branch?

Not always. Online banks often pay higher rates than branches of the same bank because their costs are lower. Some banks also offer promotional rates online that don't apply in branches. Always check the specific rate for the channel—online or branch—where you plan to open the CD.

What's the difference between APY and APR on a CD?

APY (Annual Percentage Yield) includes the effect of compounding and is what banks use to advertise CD rates. APR (Annual Percentage Rate) does not include compounding. For CDs, always look at the APY because that's your actual return.

Do I have to pay taxes on CD interest?

Yes. CD interest is taxable income in the year you earn it. 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.

What happens when my CD matures?

When your CD reaches its maturity date, the bank deposits your principal plus all earned interest into your account. You then have a set number of days (usually 7 to 10) to decide what to do with the money—withdraw it, open a new CD, or move it elsewhere. If you don't act, many banks automatically renew the CD at the current rate.
