A money market account is a hybrid between a savings account and a checking account, with interest rates tied to money market rates
A money market account (MMA) holds your cash and pays you interest, like a savings account does. But it also gives you a limited number of checks or debit card transactions per month, like a checking account does. The interest rate fluctuates based on what's happening in the money market — the short-term lending market where banks and large institutions trade funds overnight and for periods of a few months.
The rate you earn depends on the current federal funds rate and what your specific bank or credit union decides to offer. When the Federal Reserve raises rates, money market account rates typically rise within weeks or months. When rates fall, so does what you earn. This is different from a fixed-rate CD, where your rate is locked in for the entire term.
Most money market accounts require a higher opening deposit than a regular savings account — often $2,500 to $10,000, though this varies by institution. In exchange, you get a higher interest rate. The tradeoff is that you can only make a limited number of withdrawals per month (usually six) before fees kick in.
Key Takeaways
- Money market accounts pay interest that moves up and down with market rates, so your earnings change over time rather than staying fixed.
- You get check-writing or debit card access, but only a limited number of transactions per month before your bank charges a fee.
- Most require a higher minimum deposit than savings accounts, typically between $2,500 and $10,000 depending on the bank.
- The interest rate is higher than a savings account but lower than a CD, making it useful for money you want to access occasionally but not frequently.
How the interest rate works
Your money market account rate is not set by your bank alone. Banks watch the federal funds rate — the rate at which banks lend reserve balances to each other overnight. When the Federal Reserve signals that rates are rising, banks know they will have to pay more to attract deposits, so they raise their money market rates. When the Fed signals rates are falling, banks lower what they offer.
The lag between a Fed rate change and a change in your account rate is usually one to three months. Your bank is not required to pass along the full increase or decrease, so two banks offering money market accounts may respond differently to the same Fed move. One might raise its rate by 0.25% while another raises it by 0.10%.
This means you should check your account's rate periodically — especially if you have held the account for more than a year. Rates that were competitive when you opened the account may have fallen behind what other banks are now offering. Moving your money to a higher-paying account costs nothing and takes a few days.
Withdrawal limits and how they affect you
Federal rules allow you to make up to six withdrawals or transfers per month from a money market account before your bank can charge you a fee. This includes debit card transactions, checks you write, and transfers to another account. Some banks charge $10 to $25 per withdrawal over the limit; others may close your account if you exceed the limit repeatedly.
This restriction exists because money market accounts are designed for money you need to access occasionally, not money you spend from daily. If you find yourself hitting the withdrawal limit regularly, a regular checking account or high-yield savings account would serve you better. A high-yield savings account has no withdrawal limit and often pays nearly as much interest as a money market account.
The six-withdrawal rule does not apply to ATM withdrawals at your bank's own machines, and it does not apply to withdrawals you make in person at a branch. It applies only to remote withdrawals — debit card purchases, checks, and transfers initiated online or by phone.
Money market accounts versus savings accounts
A money market account pays more interest than a standard savings account at the same bank, but it requires a higher minimum deposit and limits how often you can withdraw. A high-yield savings account, by contrast, often pays as much or more than a money market account, requires a lower minimum (sometimes $0), and has no withdrawal limits.
The main reason to choose a money market account over a high-yield savings account is if you want check-writing ability. Some people like having the option to write a check directly from their savings, even if they rarely use it. If you do not need that feature, a high-yield savings account is usually the simpler choice.
| Feature | Money Market Account | High-Yield Savings | Regular Savings |
|---|---|---|---|
| Interest rate | Variable, currently 4% to 5% | Variable, currently 4% to 5% | Often under 0.5% |
| Minimum deposit | $2,500 to $10,000 | $0 to $1,000 | $0 to $500 |
| Withdrawal limit | 6 per month | None | None |
| Check writing | Yes, limited | No | No |
When a money market account makes sense
A money market account works well if you have $5,000 or more sitting in a regular savings account earning almost nothing, and you want a higher rate without locking your money away in a CD. It also works if you occasionally need to write a check from savings — for example, if you keep an emergency fund and want the option to pay a contractor or vendor directly from that account.
A money market account is not the right choice if you spend from savings frequently, if you have less than $2,500 to deposit, or if you want your rate to stay the same for a set period. For frequent spending, use a checking account. For smaller amounts, use a high-yield savings account. For a may provide rate, use a CD.
Money market accounts are also useful as a bridge between a checking account and an emergency fund. Some people keep their regular spending money in checking, their emergency fund in a money market account (for higher interest and limited access), and their longer-term savings in CDs.
FDIC protection and safety
Money market accounts at banks are covered by FDIC insurance up to $250,000 per depositor, per bank. This means if your bank fails, the government guarantees your money up to that limit. Money market accounts at credit unions are covered by NCUA insurance with the same $250,000 limit.
If you have more than $250,000 to deposit, you can open accounts at multiple banks to keep all your money insured. For example, $250,000 at Bank A and $250,000 at Bank B are both fully covered. The insurance applies to the total of all your accounts at one institution, so having two money market accounts at the same bank does not double your coverage.
How to open a money market account
You can open a money market account online, by phone, or in person at most banks and credit unions. You will need to provide your name, address, Social Security number, and employment information. The bank will verify your identity and check your banking history through ChexSystems, a database that tracks account closures and fraud.
Once your account is open, you can fund it by transferring money from another bank account, depositing a check by mail or mobile app, or making a wire transfer. Most banks make the funds available within one to three business days. Your first interest payment usually appears within 30 days, though timing varies by institution.
Before you open an account, compare rates across at least three banks or credit unions. Rates change frequently, and a difference of 0.5% on $10,000 means $50 per year. Online banks and credit unions often offer higher rates than brick-and-mortar banks because they have lower overhead costs.
Frequently Asked Questions
Can I lose money in a money market account?
No. Your principal is protected by FDIC or NCUA insurance, and the interest rate can only go up or down — it cannot turn negative. The only way to lose money is if you withdraw funds and the account balance drops, but that is your choice, not a loss from the account itself.
What happens if I exceed the six-withdrawal limit?
Your bank will charge a fee, usually $10 to $25 per withdrawal over the limit. If you repeatedly exceed the limit, some banks may convert your account to a checking account or close it. Check your bank's specific policy before opening the account.
Is a money market account better than a CD?
It depends on your needs. A CD locks your money for a set term (three months to five years) and pays a fixed rate, so you know exactly what you will earn. A money market account lets you access your money anytime but the rate changes. Choose a CD if you will not need the money for a specific period; choose a money market account if you want flexibility.
Do I pay taxes on money market account interest?
Yes. Interest earned in a money market account is taxable income. Your bank will send you a 1099-INT form at tax time showing how much interest you earned. You report this on your tax return.
Can I transfer money between my money market account and checking account without hitting the withdrawal limit?
Transfers between your own accounts at the same bank usually do not count toward the six-withdrawal limit, but this varies by bank. Ask your bank before you open the account to confirm their specific policy.
