A money market account is a hybrid savings product that combines features of checking and savings accounts, usually paying higher interest than a regular savings account in exchange for keeping a larger balance and limiting your withdrawals.
Money market accounts are offered by banks and credit unions. They sit between a traditional savings account and a money market fund (which is different—it's an investment product). The account holds your cash, earns interest, and lets you write checks or make transfers, but with restrictions: most require you to keep a minimum balance (often $2,500 to $25,000, though this varies by institution), and they limit how many withdrawals you can make per month.
The tradeoff is straightforward. You keep more money sitting in the account, you follow the withdrawal limits, and the bank pays you a higher interest rate than it would on a basic savings account. The rate changes with market conditions—it's not locked in like a CD—so your earnings fluctuate month to month.
Key Takeaways
- Money market accounts pay interest rates higher than regular savings accounts but require you to maintain a minimum balance that varies by bank, typically between $2,500 and $25,000.
- You can write checks and make transfers from a money market account, but most banks limit you to a set number of withdrawals per month (often six), and exceeding that limit triggers a fee.
- The interest rate is variable, meaning it moves up and down with market conditions rather than staying fixed, so your monthly earnings change.
- Your deposits are insured by the FDIC (at banks) or NCUA (at credit unions) up to $250,000, making the account itself safe even if the institution fails.
How the interest rate and minimum balance work together
The interest rate on a money market account is set by the bank and changes periodically—usually weekly or monthly—based on what the Federal Reserve does and what other banks are offering. When rates are rising, your earnings go up. When rates fall, so does what you earn. You don't control this, and you can't lock in a rate the way you can with a certificate of deposit.
The minimum balance requirement is the price of entry. If your balance drops below it, you typically pay a monthly fee (often $10 to $25) until you bring it back up. Some banks waive the fee if you maintain the minimum; others charge it regardless. Read the account terms carefully, because the fee can wipe out several months of interest on a small balance.
Because of these requirements, a money market account makes sense only if you have cash you're not going to need immediately but might need within a year or two. If you have $500 to your name, a regular savings account is the right choice. If you have $10,000 sitting around and you know you won't touch it for at least six months, a money market account can earn you more than a savings account would.
Withdrawal limits and what happens when you exceed them
Most money market accounts allow you to make a limited number of withdrawals per month—commonly six, though some banks allow more or fewer. This includes checks you write, transfers you initiate, and debit card withdrawals. It does not include ATM withdrawals at the bank's own machines, which usually don't count against the limit.
If you exceed the limit, the bank charges a fee per excess withdrawal, typically $10 to $25 each. Some banks will simply decline the transaction instead. Either way, the account is designed to discourage frequent access—it's meant for money you're holding, not money you're moving around constantly.
This is the main reason money market accounts don't work well as checking accounts, even though you can write checks on them. If you need to access your money more than six times a month, you'll pay penalties or face declined transactions. For everyday spending, use a checking account. Use a money market account for a reserve or a goal you're saving toward.
Money market accounts versus savings accounts and CDs
| Feature | Money Market Account | Regular Savings Account | Certificate of Deposit (CD) |
|---|---|---|---|
| Interest rate | Variable, higher than savings | Variable, lower | Fixed for the term |
| Minimum balance | Usually $2,500–$25,000 | Often $0–$500 | Varies, often $500–$2,500 |
| Withdrawal limit | Usually 6 per month | Usually 6 per month | None until maturity; early withdrawal penalty applies |
| Can write checks | Yes | No | No |
| Best for | Money you might need within 1–2 years | Emergency fund or short-term savings | Money you won't need for a set period |
A regular savings account is simpler: lower interest, no minimum balance (or a very small one), and the same withdrawal limits. Use it if you're building an emergency fund or saving for something within the next few months.
A CD locks your money away for a set term—three months, one year, five years—and pays a fixed rate. If you withdraw early, you pay a penalty. Use a CD if you know you won't need the money for a specific period and you want to lock in a rate before rates fall.
FDIC and NCUA insurance on money market accounts
Money market accounts held at banks are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor, per bank. If the bank fails, your money is protected up to that limit. Money market accounts at credit unions are insured by the National Credit Union Administration (NCUA) under the same $250,000 limit.
This insurance covers the account itself, not the interest rate or the value of your balance. If you have $100,000 in a money market account and the bank fails, you get your $100,000 back (plus any interest earned up to the point of failure). If you have $300,000, you get $250,000 back from insurance; the rest is unsecured and you may lose it.
The $250,000 limit applies per depositor per bank, so if you have accounts at two different banks, each is insured separately. If you have multiple accounts at the same bank—a money market account and a savings account, for example—they share the $250,000 limit.
When a money market account makes financial sense
A money market account is worth considering if you have $5,000 or more that you're not going to spend in the next three to six months but might need within one to two years. Examples: a down payment fund you're building, money set aside for a car purchase, or a buffer beyond your emergency fund.
It's not worth it if you have less than the minimum balance, because the fee will eat your interest. It's also not the right choice if you need to access the money frequently—the withdrawal limits and fees make it expensive to use like a checking account.
Compare rates across banks before you open one. Money market rates vary significantly, and a bank offering 4.5% is meaningfully better than one offering 3.8%, especially over a year or two. Check the minimum balance requirement and the fee structure. Some banks charge a monthly fee if you fall below the minimum; others only charge it if you make excess withdrawals. The terms matter.
How to open a money market account
Most banks and credit unions offer money market accounts online or in person. The process is the same as opening any deposit account: you provide your name, address, Social Security number, and initial deposit. Many banks let you open one entirely online in 10 to 15 minutes.
Before you open, confirm three things: the current interest rate (it changes, so don't rely on what you saw last week), the minimum balance requirement, and the fee structure. Ask specifically what happens if your balance drops below the minimum and how many withdrawals you get per month. Write down the answers or take a screenshot.
Once the account is open, you can usually set up automatic transfers from your checking account to fund it, or deposit a check online. You'll receive checks (if the bank provides them) and can set up bill pay or transfers through the bank's website or app.
Frequently Asked Questions
Can I use a money market account like a checking account?
Technically yes—you can write checks and make transfers—but the withdrawal limit makes it impractical. Most banks limit you to six withdrawals per month, and exceeding that triggers a fee. If you need to access your money more than six times monthly, use a checking account instead.
What happens if my balance falls below the minimum?
You'll usually pay a monthly fee, typically $10 to $25, until your balance comes back up. Some banks waive the fee if you bring the balance back within a set period; others charge it every month you're below the minimum. Check your account agreement to know your bank's policy.
Is the interest rate may provide?
No. Money market account rates are variable, meaning they change with market conditions. Your bank can raise or lower the rate at any time, and you have no control over it. If you want a may provide rate, open a CD instead.
How is a money market account different from a money market fund?
A money market account is a bank deposit product insured by the FDIC. A money market fund is an investment product that buys short-term debt securities and is not FDIC-insured. For most people saving cash, a money market account is the safer choice.
Can I have multiple money market accounts at different banks?
Yes. Each account at a different bank is insured separately up to $250,000 by the FDIC. This is useful if you want to spread your savings across institutions or take advantage of different rates at different banks.
