A money market account is a hybrid savings product that combines features of checking and savings accounts
A money market account (MMA) is a deposit account offered by banks and credit unions that pays interest on your balance and lets you write checks or make transfers, but with limits on how often you can withdraw. The interest rate is usually higher than a regular savings account but lower than a certificate of deposit (CD). The tradeoff is that the bank restricts the number of withdrawals you can make each month—typically six per statement cycle—and may require a higher opening deposit than a standard savings account.
Money market accounts are FDIC-insured at banks (or NCUA-insured at credit unions) up to $250,000 per depositor, per institution. This means your money is protected if the bank fails. The account is not an investment product; it is a bank deposit, so you will not own stocks or mutual funds inside it.
Key Takeaways
- Money market accounts pay interest rates higher than savings accounts but require you to limit withdrawals to six per month, or face fees.
- Most banks require a minimum opening deposit—often $2,500 to $10,000—and charge a monthly fee if your balance falls below that minimum.
- You can write checks or use a debit card from a money market account, but frequent withdrawals will trigger penalties or conversion to a regular savings account.
- The interest rate on a money market account changes with market conditions and varies by bank, so rates at one institution may be much higher or lower than another.
How the withdrawal limit works and what happens if you exceed it
Federal rules allow you to make up to six withdrawals or transfers per month from a money market account without penalty. A withdrawal includes any transfer out of the account—whether you write a check, use a debit card, make an ACH transfer, or request a wire. Deposits do not count toward the limit.
If you exceed six withdrawals in a statement cycle, the bank may charge a fee (typically $25 to $35 per excess withdrawal) or convert your account to a regular savings account with no check-writing privileges. Some banks will simply decline the transaction. The six-withdrawal rule is a federal regulation, so all banks enforce it, though the penalty varies.
This limit makes money market accounts better for people who want to earn interest on money they do not touch often, rather than for frequent spending. If you need to withdraw money multiple times a month, a regular checking account is a better fit.
Interest rates and how they compare to other accounts
Money market accounts typically offer higher interest rates than savings accounts because the bank can count on your money staying in the account longer. The exact rate depends on the current economic environment, the bank's funding needs, and your account balance. Banks often offer tiered rates—meaning you earn a higher percentage if you maintain a larger balance.
As of late 2024, money market rates at online banks range from roughly 4% to 5% annual percentage yield (APY), while rates at traditional brick-and-mortar banks are often lower, sometimes 0.5% to 1.5% APY. Rates change frequently, so comparing banks before you open an account matters. A CD typically locks in a fixed rate for a set term (three months to five years), while a money market rate can change at any time after you open the account.
The interest is calculated daily and paid monthly or quarterly, depending on the bank. You do not have to do anything to earn it—the bank credits it automatically to your account.
Minimum balance requirements and monthly fees
Most banks require a minimum opening deposit to open a money market account, ranging from $1,000 to $25,000 depending on the institution. Some online banks have no minimum, while premium money market accounts at large banks may require $100,000 or more.
If your balance falls below the minimum, the bank typically charges a monthly maintenance fee, usually $10 to $25. Some banks waive the fee if you maintain direct deposit or set up automatic transfers. Others waive it if you keep a certain balance in a linked checking account. Read the account terms carefully—the fee structure varies widely.
The combination of a high minimum balance requirement and a monthly fee can erase the interest you earn if your balance is small. For example, if you earn $5 per month in interest but pay a $15 monthly fee, you are losing money. This is why money market accounts make sense only if you have enough cash to meet the minimum and keep it there.
When a money market account makes sense versus other options
A money market account is useful if you have a lump sum of money—such as an emergency fund or money set aside for a down payment—that you want to earn interest on without locking it away in a CD. You can access the money if you need it (within the six-withdrawal limit), and you earn more interest than you would in a regular savings account.
A money market account is not the right choice if you need to make frequent withdrawals, if you have less than the minimum balance, or if you want to invest in stocks or bonds. For frequent spending, use a checking account. For money you will not touch for months or years, a CD or high-yield savings account may be better. For investing, you need a brokerage account, not a bank account.
Money market accounts also work well as a bridge between a checking account and savings. You can park money there temporarily while you decide what to do with it, earn some interest, and still access it quickly if plans change.
How to open a money market account and what documents you need
Opening a money market account is straightforward. You can do it online, by phone, or in person at a bank branch. You will need a government-issued photo ID (driver's license or passport), your Social Security number, and proof of address (a recent utility bill or bank statement). Some banks also ask for employment information.
The bank will run a background check through ChexSystems, a database that tracks banking history. If you have unpaid overdrafts or fraud flags at other banks, you may be denied. Most people are approved instantly or within one business day.
Once approved, you fund the account by transferring money from another bank account (via ACH, which takes one to three business days) or by depositing a check or cash at a branch. Some banks mail you a debit card and checks; others issue them immediately. You can start earning interest as soon as the deposit clears.
What happens to your money if the bank fails
Money in a money market account at a bank is protected by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor, per bank. This means if the bank goes out of business, the FDIC will return your money, up to that limit. This protection is automatic—you do not have to do anything or pay a fee.
If you have more than $250,000, only the first $250,000 is protected at that bank. To protect additional funds, you would need to open accounts at different banks or use different account ownership categories (such as a joint account or a retirement account), each of which has its own $250,000 protection limit.
In practice, bank failures are rare, and the FDIC has never failed to return insured deposits. The protection exists so you can keep your money in a bank without worrying about losing it if the institution fails.
Frequently Asked Questions
Can I use a debit card to withdraw money from a money market account?
Yes, most banks issue a debit card with a money market account. However, each debit card transaction counts toward your six-withdrawal limit per month. If you use the card more than six times, you may be charged a fee or the account may be converted to a savings account.
What if I need to withdraw more than six times in a month?
If you exceed six withdrawals, the bank will charge a fee (typically $25 to $35 per excess withdrawal) or convert your account to a regular savings account with no check-writing privileges. Some banks decline the transaction instead. If you need frequent access, a checking account is a better choice.
Do I pay taxes on the interest I earn?
Yes. The interest you earn on a money market account is taxable income. The bank will send you a 1099-INT form at the end of the year showing how much interest you earned, and you must report it on your tax return. The interest is taxed at your ordinary income tax rate.
Can the bank lower my interest rate after I open the account?
Yes. Money market rates are variable, meaning the bank can change them at any time. The bank must notify you of a rate change, usually by email or mail, but it can lower the rate without your permission. If rates drop significantly, you can move your money to a different bank offering a higher rate.
Is a money market account the same as a money market fund?
No. A money market account is a bank deposit insured by the FDIC. A money market fund is an investment product sold by brokerages that invests in short-term debt securities. Money market funds are not FDIC-insured and can lose value, though the risk is usually low. They are different products with different protections.
