A money market account is a savings account that pays you more interest, but requires you to keep a larger balance and limits how often you can withdraw

A money market account (MMA) sits between a regular savings account and a certificate of deposit. The bank pays you a higher interest rate on your balance — sometimes significantly higher — in exchange for two things: you keep a minimum amount of money in the account (often $2,500 to $10,000, though this varies by bank), and you can only make a limited number of withdrawals each month before fees kick in.

The account works like a savings account in most ways. You deposit money, it earns interest, and you can withdraw it whenever you need to. The difference is that the interest rate is usually better because the bank can count on your money staying there longer and in larger amounts. The withdrawal limit exists because the account is technically a savings product, not a checking product — the bank structures it that way for regulatory reasons.

Money market accounts are useful if you have money you want to keep safe and earning interest, but you might need to access it within a few months or a year. They are not useful if you need to make frequent withdrawals, or if you cannot meet the minimum balance requirement.

Key Takeaways

  • Money market accounts pay higher interest rates than regular savings accounts, but require a minimum balance that varies by bank.
  • You can usually make three to six withdrawals per month before the bank charges you a fee for excess withdrawals.
  • The account comes with a debit card or checkbook at many banks, so you can access your money without going to a branch.
  • If your balance drops below the minimum, you may lose the higher interest rate or pay a monthly fee.

How the interest rate and minimum balance work together

The interest rate on a money market account depends on two things: what the bank decides to offer, and how much money you keep in the account. Banks publish their rates publicly, and they change based on what the Federal Reserve does with interest rates — when the Fed raises rates, banks usually raise their MMA rates too, and vice versa.

The minimum balance requirement is set by each bank. Some banks require $2,500, others $5,000 or $10,000. A few banks have no minimum at all, though they usually offer a lower interest rate in that case. The minimum is the amount you must keep in the account at all times. If your balance drops below it — say you withdraw $500 and fall short — the bank will either charge you a monthly fee (often $10 to $25) or drop your interest rate to match a regular savings account.

This means the real cost of a money market account is not just the interest you earn, but also the opportunity cost of keeping that much money sitting there. If you have $5,000 in a money market account earning 4% interest, you are earning about $200 a year. That is real money, but only if you were not going to use that $5,000 for something else.

The withdrawal limit and what happens when you exceed it

Most money market accounts allow you to make three to six withdrawals per month without penalty. This includes transfers to other accounts, checks you write, and debit card withdrawals. The exact number depends on the bank and the account type.

If you exceed the limit, the bank charges a fee — typically $10 to $25 per excess withdrawal. Some banks will simply decline the withdrawal and charge you a fee. Others will allow it but charge you retroactively. A few banks will close the account or convert it to a regular savings account if you repeatedly exceed the limit.

The withdrawal limit exists because federal banking rules historically restricted how many times you could withdraw from a savings account each month. Those rules have loosened in recent years, and many banks have removed the limit entirely. But some banks still enforce it, so you need to check your specific bank's policy before opening an account.

Money market accounts versus savings accounts and checking accounts

A regular savings account has no withdrawal limit (at most banks) and no minimum balance requirement. The trade-off is that the interest rate is lower — often 0.01% to 0.5%, compared to 3% to 5% for a money market account. A regular savings account is better if you need to make frequent withdrawals or if you have a small amount of money to save.

A checking account has unlimited withdrawals and is designed for frequent use. It usually pays no interest at all, or interest so low it rounds to zero. You use it for bills, groceries, and everyday spending. A money market account is not a replacement for checking.

A certificate of deposit (CD) pays even higher interest than a money market account, but you cannot withdraw the money before a set date (usually three months to five years) without paying a penalty. A money market account is more flexible because you can withdraw whenever you want, as long as you stay within the monthly limit.

What happens to your money if the bank fails

Money in a money market account is protected by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per account holder per bank. This means if the bank fails, the FDIC will reimburse you for the full balance, up to that limit. This protection applies whether the money is in a checking account, savings account, or money market account.

The $250,000 limit applies per depositor per bank. If you have $250,000 in a money market account at Bank A and $250,000 in a money market account at Bank B, both are fully protected. If you have $250,000 in a money market account and $250,000 in a savings account at the same bank, only $250,000 total is protected — the two accounts are combined for FDIC purposes.

When a money market account makes sense for your situation

A money market account is useful if you have a specific goal that is three to twelve months away — a down payment on a car, a vacation, a home repair fund — and you want to earn interest on the money while you wait. It is also useful if you have an emergency fund and want it to earn more than a regular savings account, as long as you can keep the minimum balance untouched.

A money market account is not useful if you need to make frequent withdrawals (more than six per month), if you cannot meet the minimum balance, or if you need the money within a few weeks. It is also not useful if you are comparing it to a high-yield savings account at an online bank — many online banks now offer savings accounts with no minimum balance and interest rates that match or exceed money market accounts.

Before opening a money market account, compare the interest rate, minimum balance, withdrawal limit, and monthly fees across at least three banks. The difference between a 4% rate and a 5% rate on $10,000 is $100 per year — enough to matter.

How to open a money market account

Opening a money market account takes about 10 to 15 minutes online or in person. You will need a government-issued ID, your Social Security number, and proof of address (a recent utility bill or bank statement). Some banks also ask for your employment information.

You can open an account at a bank branch, on the bank's website, or sometimes by phone. Online banks typically offer the fastest process — you can complete the application in minutes and fund the account by transferring money from another bank account. In-person applications at a branch take longer but let you ask questions face-to-face.

Once the account is open, you fund it by transferring money from another account, depositing a check, or making a direct deposit. The bank will send you a debit card and checks (if the account includes them) within 7 to 10 business days. You can start earning interest immediately, even before the physical card arrives.

Frequently Asked Questions

Can I use a money market account like a checking account?

Some money market accounts come with a debit card and checkbook, so you can use them like a checking account. However, you are limited to three to six withdrawals per month before fees apply. If you need unlimited access, use a checking account instead and keep your money market account separate for savings.

What if I need to withdraw all my money before the month is over?

You can withdraw all your money whenever you want — there is no penalty for closing the account or emptying it. You will only pay a fee if you exceed the monthly withdrawal limit. Once you close the account, you lose the interest rate, so plan accordingly.

Do I have to keep the minimum balance every single day?

Most banks require you to maintain the minimum balance at the end of each day, or sometimes at the end of each month. If your balance dips below the minimum for one day, you may not be charged a fee. Check your bank's specific policy, because it varies.

Is the interest rate may provide to stay the same?

No. Banks can change the interest rate on a money market account at any time, usually with a few days' notice. When the Federal Reserve raises or lowers interest rates, banks adjust their rates accordingly. Your rate could go up or down depending on market conditions.

What is the difference between a money market account and a money market fund?

A money market account is a bank product protected by FDIC insurance. A money market fund is an investment product sold by brokerages and mutual fund companies, and it is not FDIC-insured. They are different products with different risks, even though the names are similar.
