A money market account is a hybrid between a savings account and a checking account, held at a bank or credit union

A money market account (MMA) combines features of two different account types. Like a savings account, it earns interest on your balance. Like a checking account, it gives you the ability to withdraw money and write checks. The trade-off is that you can only make a limited number of withdrawals per month—typically six—before the bank charges a fee or restricts further access.

The account is called "money market" because the bank uses your deposited funds to invest in short-term, low-risk securities like Treasury bills and commercial paper. Those investments generate the interest the bank pays you. Your money stays yours; the bank is straightforward putting it to work on your behalf.

Money market accounts are FDIC-insured at banks and NCUA-insured at credit unions, meaning your balance is protected up to $250,000 per account owner per institution if the bank or credit union fails. This insurance applies regardless of how much interest you earn.

Key Takeaways

  • Money market accounts earn interest like savings accounts but allow limited check-writing and debit card access like checking accounts.
  • Withdrawal limits typically cap you at six transactions per month before fees kick in or the account is restricted.
  • Interest rates on money market accounts fluctuate with the Federal Reserve's rate changes and vary significantly between institutions.
  • Your deposits are insured up to $250,000 by the FDIC (at banks) or NCUA (at credit unions), protecting your principal.
  • Money market accounts require a higher minimum balance than many savings accounts, often $2,500 or more to open or maintain the advertised rate.

How interest rates and minimum balances work

The interest rate on a money market account is not fixed. It moves up and down based on what the Federal Reserve does with its benchmark interest rate. When the Fed raises rates, banks typically raise the rates they offer on money market accounts within weeks. When the Fed cuts rates, banks follow. The exact timing and amount vary by bank—some move quickly, others lag behind.

Banks also tier their rates by balance. A bank might offer 4.50% on balances under $10,000, 4.75% on balances from $10,000 to $50,000, and 5.00% on balances above $50,000. Your rate depends on which tier your balance falls into. If your balance drops below the minimum required to earn the advertised rate, you move to a lower tier automatically.

Most money market accounts require a minimum balance to open—often $2,500 to $10,000—and to maintain the stated interest rate. If your balance falls below that minimum, the bank may charge a monthly fee (typically $10 to $25) or drop you to a lower interest rate. Some banks waive the minimum if you set up automatic monthly deposits.

The withdrawal limit and what happens when you exceed it

Federal rules historically capped withdrawals at six per month, though that rule was suspended in 2020 and has not been formally reinstated. However, most banks still enforce their own six-withdrawal limit as a contractual term in the account agreement. This limit typically includes transfers to other accounts, checks written, and debit card withdrawals—but not ATM withdrawals or in-person withdrawals at a branch.

If you exceed the limit, the bank's response depends on its policy. Some charge a fee per excess transaction (usually $10 to $25). Others freeze the account temporarily or convert it to a regular savings account. A few banks straightforward decline the transaction. You should check your account agreement or call the bank to know what happens at your specific institution.

The withdrawal limit makes money market accounts less useful for frequent spending. If you need to access your money regularly, a regular checking account is a better fit. Money market accounts work best when you have a lump sum you want to earn interest on while keeping it accessible for occasional needs.

Money market accounts versus savings accounts and money market funds

A regular savings account also earns interest and is FDIC-insured, but it typically offers a lower interest rate than a money market account. Savings accounts also have fewer withdrawal restrictions—many banks allow unlimited transfers now. The trade-off is that you give up check-writing and debit card access. If you rarely need to write checks or make transfers, a savings account may be simpler.

A money market fund is a different product entirely, despite the similar name. It is a type of mutual fund that invests in short-term securities, and it is not FDIC-insured. Money market funds are offered by investment firms, not banks. They are not bank accounts. If you see "money market fund" in an investment account, that is not the same as a money market account at a bank.

A money market account sits between the two: more interest than a savings account, more flexibility than a certificate of deposit (CD), but less flexibility than a checking account and lower returns than a money market fund or stock investment.

When a money market account makes sense for your situation

A money market account works well if you have money you want to earn interest on but may need to access within the next few months or years. Examples include an emergency fund you want to grow, money you are saving for a down payment, or funds set aside for a planned expense six months away. The interest rate is higher than a savings account, and you can write checks or use a debit card if you need the money quickly.

A money market account is less useful if you spend from savings frequently. The six-withdrawal limit means you will hit fees quickly if you are moving money in and out regularly. In that case, a checking account or high-yield savings account is more practical.

A money market account is also less useful if you have a very small balance. If you only have $500 to $1,000, the interest you earn will be modest, and you may not meet the minimum balance to avoid fees. A regular savings account with no minimum might serve you better.

How to compare money market accounts across banks and credit unions

The interest rate is the most visible difference, but it is not the only one that matters. When comparing accounts, check: the current interest rate and what tier your expected balance falls into; the minimum balance required to open and to earn that rate; what fees explore if you fall below the minimum; how many withdrawals are allowed per month; whether the bank charges fees for excess withdrawals or converts the account; and whether you can write checks or use a debit card, or only transfer funds.

Interest rates change frequently, so a rate that is highest today may not be highest next month. What matters more is the bank's pattern: does it move rates quickly when the Fed moves, or does it lag? Does it offer competitive rates across balance tiers, or only for very large balances? Reading recent customer reviews on banking sites can tell you whether a bank is responsive to rate changes.

Credit unions often offer competitive rates on money market accounts and may have lower minimum balances than banks. However, you must be a member to open an account. Membership requirements vary—some credit unions are open to anyone in a geographic area, others require membership in a specific employer or organization.

The tax treatment of money market account interest

Interest you earn on a money market account is taxable income. The bank will send you a Form 1099-INT at the end of the year reporting the interest you earned, and you must report that amount on your federal tax return. The interest is taxed as ordinary income at your marginal tax rate, not at a lower capital gains rate.

If you earned $10 or more in interest during the year, the bank must issue the 1099-INT. If you earned less, the bank may not issue one, but you are still required to report the interest on your return. Keep your own records of interest earned if the amount is small.

Some states also tax interest income, while others do not. Check your state's tax rules if you live in a state with an income tax.

Frequently Asked Questions

Can I lose money in a money market account?

No. Your principal is protected by FDIC or NCUA insurance up to $250,000. The bank cannot invest your money in stocks or other volatile assets. The only way you lose money is if you withdraw funds and pay a fee that exceeds your interest earnings, which is unlikely.

What happens if the bank fails?

Your balance up to $250,000 is protected by the FDIC (at banks) or NCUA (at credit unions). The insuring agency will transfer your account to another institution or pay you directly. You will not lose your money, though there may be a brief delay in access while the transfer happens.

Can I have multiple money market accounts?

Yes, but the FDIC insurance limit applies to all money market accounts you own at the same bank combined. If you have two money market accounts at the same bank totaling $300,000, only $250,000 is insured. To insure more, you would need accounts at different banks.

Is the interest rate may provide?

No. The rate can change at any time, and banks typically change rates without notice. Some banks offer a promotional rate for a limited time (like 5.25% for the first three months), after which the rate drops to the standard rate. Always read the fine print about rate terms.

What if I need to withdraw more than six times in a month?

You can make in-person withdrawals at a branch or ATM withdrawals without counting against the limit at most banks. The limit applies to transfers and checks. If you need frequent access to your money, a regular checking account or high-yield savings account is a better choice.
