A money market account is a hybrid between a savings account and a checking account that pays interest on your balance
Money market accounts let you earn interest on money you keep in the account, unlike a standard checking account where your balance sits flat. You can write checks and use a debit card, but usually with limits — most banks cap the number of checks you can write per month or the number of withdrawals you can make. The tradeoff is that your money grows slightly instead of staying dormant, and you keep most of the convenience of a checking account.
Banks offer money market accounts because they can lend out more of your money when you agree to keep it there longer and limit how often you move it. That's why they pay you interest in return. The interest rate varies by bank and changes with the federal funds rate, so what you earn this month may differ next month.
Key Takeaways
- Money market accounts earn interest on your balance, but most banks limit you to three to six withdrawals per month.
- The interest rate is variable, meaning it can go up or down based on what the Federal Reserve does and what your bank decides.
- You can write checks and use a debit card on most money market accounts, though some banks restrict check writing to a set number per month.
- Money market accounts require a higher opening deposit than regular checking accounts, often $2,500 to $25,000 depending on the bank.
- Your money is insured up to $250,000 by the FDIC if the bank fails, the same as a checking account.
How interest rates and minimum balances work
The interest rate on a money market account is variable, which means your bank can change it whenever they want. Most banks tie their rates loosely to the federal funds rate set by the Federal Reserve, so when the Fed raises rates, banks usually raise theirs too — but not always by the same amount, and not always right away. When the Fed cuts rates, banks often cut theirs faster than they raised them.
Most money market accounts also require a minimum opening deposit and a minimum balance to keep the account open. These minimums vary widely: some banks ask for $2,500, others for $10,000 or more. If your balance drops below the minimum, the bank may charge a monthly fee, lower your interest rate, or close the account. A few banks offer money market accounts with no minimum, but their interest rates are usually lower than banks that do require one.
The interest you earn is calculated daily but usually paid monthly. If you have $10,000 in the account and the rate is 4.50% annual percentage yield (APY), you earn roughly $37.50 that month — though the exact amount depends on how many days are in the month and the bank's calculation method.
Withdrawal limits and how they affect your access to money
Federal rules once capped withdrawals from money market accounts at six per month, but that rule was suspended in 2020 and has not been reinstated. However, individual banks still impose their own limits, and these vary. Some banks allow unlimited withdrawals, others cap you at three per month, and some charge a fee if you exceed a certain number — say, six withdrawals free, then $10 per withdrawal after that.
The limit usually applies to transfers and electronic withdrawals, not always to in-person withdrawals at a branch or ATM. Check your bank's specific rules before opening an account, because if you need to move money frequently, a money market account may frustrate you. If you regularly withdraw money more than a few times a month, a regular checking account is usually the better choice.
Some banks also restrict how many checks you can write per month — often three to ten — while others allow unlimited check writing. This is separate from the withdrawal limit, so you could hit one limit without hitting the other. The combination of both restrictions means you need to plan ahead if you use a money market account for regular bills or frequent payments.
Money market accounts versus regular checking accounts
| Feature | Money Market Account | Regular Checking Account |
|---|---|---|
| Interest earned | Yes, variable rate | No, or very minimal |
| Debit card access | Yes, usually | Yes |
| Check writing | Limited (often 3–10 per month) | Unlimited |
| Withdrawals per month | Limited (varies by bank) | Unlimited |
| Minimum opening deposit | $2,500–$25,000 | $0–$500 |
| Monthly fees | $0–$25 if minimum not met | $0–$15 |
| Best for | Money you want to grow but don't need often | Daily spending and frequent transfers |
A money market account makes sense if you have a chunk of money sitting in a regular checking account earning nothing, and you don't need to touch it often. If you get paid twice a month and spend from your account weekly, a regular checking account is simpler and won't penalize you for moving money around.
The choice also depends on how much you have to deposit. If you have $3,000 and a bank requires $10,000 minimum for a money market account, you're locked out. Regular checking accounts typically have much lower or no minimum deposit requirements, making them accessible to almost anyone.
FDIC insurance and what happens if your bank fails
Money in a money market account is insured by the FDIC (Federal Deposit Insurance Corporation) up to $250,000 per depositor, per bank. This means if your bank fails, the FDIC will return your money up to that limit. The insurance covers the principal balance and any interest you've earned up to the point of failure.
If you have more than $250,000, only the first $250,000 is protected. Some people open money market accounts at multiple banks to stay under the limit at each one and keep all their money insured. FDIC insurance does not cover investment accounts or money market mutual funds — only deposit accounts at banks and credit unions that carry FDIC or NCUA insurance.
When a money market account makes financial sense
A money market account is worth considering if you have $5,000 or more that you want to keep safe and accessible but don't need for daily expenses. The interest you earn won't make you rich — at 4.50% APY, $10,000 earns $450 a year — but it's better than zero. The account also keeps your money separate from your checking account, which can help you avoid spending it on impulse.
Money market accounts are less useful if you need to move money frequently, if you have less than the minimum deposit, or if you're looking for a place to park money for the long term. For long-term savings, a high-yield savings account often has fewer restrictions and similar or better rates. For daily spending, a regular checking account is simpler.
Shop around before opening one. Interest rates and minimum balances vary widely between banks, and a difference of 1% in APY means $100 per year on a $10,000 balance. Online banks often offer higher rates than brick-and-mortar banks because they have lower overhead costs.
Frequently Asked Questions
Can I use a money market account as my main checking account?
Technically yes, but it's not ideal. If you write more than a few checks per month or make frequent transfers, you'll hit the bank's limits and face fees. A money market account works better as a secondary account where you keep money you don't touch often.
What happens if I exceed the withdrawal limit?
It depends on your bank. Some charge a fee per excess withdrawal (often $10), others lower your interest rate, and some may close the account if you repeatedly violate the limit. Check your account agreement before opening the account to know what your bank does.
Is the interest rate may provide?
No. Money market account rates are variable, meaning your bank can change the rate at any time. When rates rise, banks usually raise theirs, but when rates fall, they often cut theirs faster. You're not locked into any rate.
How much money should I have before opening a money market account?
Most banks require $2,500 to $10,000 to open one, and you need to keep that minimum in the account to avoid fees. If you have less than $2,500, a high-yield savings account at an online bank may be a better fit, as many have no minimum.
Can I lose money in a money market account?
No. Your principal is insured by the FDIC and cannot go down. You earn interest on top of what you deposit, though the rate can change. The only way to lose money is if you withdraw more than you put in.
