Money market accounts and certificates of deposit typically offer the highest rates among standard bank products

If you want the highest interest rate a bank will pay you, look at money market accounts and certificates of deposit (CDs) first. Both consistently pay more than regular savings accounts. Money market accounts sit between savings and checking—you can write checks or use a debit card, but the bank limits how often you withdraw. CDs lock your money away for a set time (three months to five years, usually) in exchange for a may provide higher rate.

The reason these accounts pay more is straightforward: the bank wants your money to stay put. A regular savings account lets you pull money out whenever you want, so the bank can't count on having it. A CD or money market account gives the bank certainty, and it pays you for that certainty. The longer you agree to lock money away in a CD, the higher the rate climbs.

Right now, CD rates run higher than money market rates at most banks, but this changes with the broader interest rate environment. When the Federal Reserve raises or lowers its benchmark rate, banks adjust what they pay within weeks or months. Checking the current rates at your own bank and comparing them to online banks (which often pay more) takes fifteen minutes and can mean the difference between earning $50 and $200 a year on $10,000.

Key Takeaways

  • Certificates of deposit (CDs) typically pay the highest rates because you agree not to touch the money for a fixed period, usually three months to five years.
  • Money market accounts pay more than savings accounts but less than CDs, and they let you access your money more often through checks or debit cards.
  • Online banks and credit unions often pay higher rates than brick-and-mortar banks for the same product, so comparing rates across institutions takes minutes and saves real money.
  • The rate you receive depends on how much you deposit, how long you lock the money away, and what the Federal Reserve's current rate environment is—all of which change over time.
  • Breaking a CD early to access your money usually costs you some or all of the interest you earned, so only lock away money you won't need.

How CDs pay more than savings accounts

A certificate of deposit is a contract between you and the bank. You give the bank a sum of money—$500, $5,000, $50,000, whatever you choose—and agree not to touch it until a specific date. In return, the bank guarantees you a fixed interest rate for that entire period. The bank knows exactly how long it will have your money, so it can lend that money out with confidence and pay you a piece of what it earns.

The tradeoff is real: if you need the money before the maturity date, the bank charges an early withdrawal penalty. This penalty is usually a certain number of months' worth of interest. A one-year CD with a three-month penalty means if you withdraw at month six, you lose three months of the interest you earned. On a $10,000 CD paying 4.5% annually, that's roughly $112 in lost interest. Some banks charge a flat fee instead, but the effect is the same—it costs you to break the contract early.

Because of this penalty, CDs work best for money you genuinely won't need. If you have an emergency fund, a CD is the wrong place for it. If you have a bonus you're saving for a house down payment in three years, a three-year CD makes sense. The bank's certainty that you won't touch the money is what lets it pay you more.

Money market accounts: higher rates with more access

A money market account blends features of savings and checking. Like a savings account, it earns interest. Like a checking account, it comes with a debit card and checkbook. The catch: the bank limits how many times per month you can withdraw or transfer money—typically six times, though this varies by bank and has changed over time.

Money market accounts pay more than regular savings accounts because of this withdrawal limit. The bank gets some of the stability it gets from a CD, just not as much. You can still access your money in a true emergency without a penalty, but you can't treat it like a checking account and pull from it constantly. The rate reflects that middle ground.

Money market rates are usually lower than CD rates for the same bank and the same time period, but higher than what a savings account pays. If you need to keep money accessible but don't need to touch it every week, a money market account is a reasonable choice. Just understand that if you exceed the withdrawal limit, the bank may charge a fee or convert the account to a regular savings account, which would drop your rate.

Why online banks and credit unions often pay more

An online bank with no physical branches pays higher rates than a bank with hundreds of locations. The reason is cost. A brick-and-mortar bank pays rent, utilities, and salaries for tellers and managers at every branch. An online bank has one or two data centers and a customer service phone line. That savings gets passed to you as a higher interest rate.

Credit unions—member-owned financial institutions rather than shareholder-owned banks—often pay more too, especially on CDs. They operate on a not-for-profit model and return earnings to members. If you belong to a credit union, compare its CD and money market rates to what online banks are offering. You may find the credit union is competitive or better.

The tradeoff is convenience. An online bank won't let you walk in and deposit cash at a teller window. Some online banks partner with ATM networks to let you withdraw cash for free, but depositing checks means mailing them or using mobile deposit. If you rarely need to deposit cash, this is no problem. If you deposit cash weekly, a local bank or credit union may be worth the lower rate.

How much the rate depends on the amount you deposit

Most banks offer the same interest rate on a CD or money market account regardless of whether you deposit $500 or $50,000. But some banks, particularly credit unions and smaller regional banks, offer tiered rates—higher rates for larger deposits. A bank might pay 4.0% on a CD if you deposit $1,000 to $9,999, and 4.5% if you deposit $10,000 or more.

This matters if you have a large sum to save. Before opening a CD or money market account, check whether the bank publishes tiered rates. If it does, you may want to deposit just enough to hit the next tier up. Depositing $10,000 instead of $9,500 to earn an extra 0.5% annually means $50 more per year—not huge, but real money for doing nothing.

Some banks also offer promotional rates for new customers or for opening multiple products at once. These rates are temporary and usually expire after three to six months, but they can be worth timing your deposit around if you're planning to save anyway.

The relationship between CD length and interest rate

The longer you lock your money away in a CD, the higher the rate you receive. A three-month CD might pay 4.0%, a one-year CD might pay 4.5%, and a five-year CD might pay 5.0%. The bank is paying you for the extra certainty and the extra time it can lend your money out.

This relationship isn't always smooth. Sometimes a one-year CD pays more than an 18-month CD, or a two-year CD pays less than a one-year. This happens when the Federal Reserve is expected to lower rates in the near future—banks pay less for longer terms because they expect rates to fall. Conversely, when rates are expected to rise, longer-term CDs pay significantly more.

The practical lesson: if you think rates are about to fall, lock in a longer-term CD now. If you think rates will rise, stick with shorter terms so you can reinvest at higher rates when the CD matures. But predicting the Federal Reserve is hard, so most people should just pick a CD length that matches when they'll actually need the money.

What happens when your CD matures

When a CD reaches its maturity date, the bank deposits the principal (your original deposit) plus all the interest you earned into your checking or savings account. You then have a choice: open a new CD at the current rate, move the money elsewhere, or leave it in savings.

Banks often send a notice 10 to 14 days before maturity telling you what will happen. If you don't do anything, many banks automatically renew the CD at the current rate for the same term. If rates have fallen, this might not be what you want. Read the notice carefully and contact the bank if you want to do something different—move the money to a higher-paying CD elsewhere, or withdraw it entirely.

This is also when you can ladder your CDs if you want. Instead of putting all your money in one five-year CD, you might open five one-year CDs with different maturity dates. Each year, one matures and you can reinvest it at the current rate. This gives you some of the higher rate of a long-term CD while keeping some money accessible each year.

Frequently Asked Questions

Can I lose money in a CD or money market account?

No. Banks insure deposits up to $250,000 per account holder per institution through the Federal Deposit Insurance Corporation (FDIC). Your principal is safe. The only way to lose interest is to withdraw early from a CD and pay the penalty, which reduces what you earn but doesn't touch your original deposit.

What's the difference between a CD and a high-yield savings account?

A high-yield savings account pays more than a regular savings account but less than a CD, and you can withdraw money anytime without penalty. CDs pay more because you agree to lock the money away. If you might need the money within a year, a high-yield savings account is safer. If you won't touch it, a CD pays more.

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 don't withdraw the money. The bank will send you a 1099-INT form at tax time showing how much interest you earned. This is one reason CDs work better for money you won't need—the interest compounds without you having to withdraw and pay taxes on it each year.

Should I open multiple CDs or one large one?

If you have more than $250,000, opening multiple CDs at different banks protects you. FDIC insurance covers $250,000 per bank, so a $500,000 deposit at one bank means $250,000 is uninsured. Splitting it between two banks keeps everything protected. If you have less than $250,000, one CD is fine, though some people ladder CDs by maturity date to keep some money accessible each year.

What if I need the money before the CD matures?

You can withdraw it, but you'll pay an early withdrawal penalty. The penalty is usually a set number of months of interest—check your CD's terms before opening it. Some banks charge smaller penalties for shorter-term CDs. If you think you might need the money, a money market account or high-yield savings account is safer than a CD.
