A money market account combines checking services with interest payments
A money market account is a hybrid product that lets you write checks and use a debit card like a checking account, but also earns interest on your balance like a savings account. Banks and credit unions offer them, and the interest rate varies by institution and by how much money you keep in the account. The tradeoff is usually a higher minimum balance requirement than a standard checking account — often $2,500 to $25,000 depending on the bank — and limits on how many withdrawals you can make per month.
Money market accounts are FDIC-insured at banks and NCUA-insured at credit unions, so your money is protected up to $250,000 per account owner per institution. They sit between a checking account and a money market fund (which is different and not insured the same way). If you keep a large balance and want some interest without moving your money around, a money market account can make sense. If you need to withdraw frequently or can't maintain a high minimum, a regular checking account or high-yield savings account may work better.
Key Takeaways
- Money market accounts let you write checks and use a debit card while earning interest, but require a higher minimum balance than checking accounts.
- Interest rates on money market accounts vary by bank and by your balance tier, and are typically lower than high-yield savings accounts.
- Most banks limit you to six withdrawals per month on money market accounts, though this rule has become less strict since 2020.
- Your deposits are insured up to $250,000 at FDIC banks and NCUA credit unions, the same as checking accounts.
How interest rates and minimum balances work
Banks set their own interest rates on money market accounts, and the rate you receive often depends on your balance tier. A bank might offer 0.01% on balances under $10,000, 0.05% on balances from $10,000 to $50,000, and 0.10% on balances over $50,000. These rates change frequently — sometimes weekly — based on what the Federal Reserve does and what the bank decides. You can check current rates on the bank's website or by calling, but rates from a year ago are not useful for comparison.
Minimum balance requirements also vary. Some banks require $2,500 to open; others ask for $10,000 or more. If your balance drops below the minimum, the bank may charge a monthly fee (often $10 to $25), drop your interest rate to nearly zero, or close the account. A few banks have no minimum, but they typically offer lower interest rates. Read the account disclosure document before opening to see what minimum applies and what happens if you fall below it.
Checking features and withdrawal limits
Money market accounts come with a debit card and checks, so you can access your money the way you would with a checking account. You can also set up direct deposit and automatic bill pay. The difference is the withdrawal limit: federal rules historically capped withdrawals at six per month, though this restriction has loosened since 2020 and many banks no longer enforce it strictly. Still, some banks do limit withdrawals, so ask before opening.
If you exceed the withdrawal limit, the bank may charge a fee per extra withdrawal (typically $5 to $10), convert your account to a checking account, or close it. Transfers to your own savings account at the same bank usually do not count as withdrawals, but transfers to other banks do. Check the account terms to understand what counts and what the penalty is if you go over.
Money market accounts versus high-yield savings accounts
The main difference is access. A money market account gives you checks and a debit card; a high-yield savings account does not. Both earn interest, and high-yield savings accounts often pay more interest than money market accounts at the same bank. High-yield savings accounts also have no withdrawal limits and no minimum balance at many online banks.
If you need to write checks or use a debit card regularly, a money market account makes sense. If you are parking money and do not need to access it often, a high-yield savings account usually pays better and has fewer restrictions. Some people keep both — a checking account for daily spending, a money market account for a large balance that needs some checking access, and a high-yield savings account for emergency funds.
Comparing money market accounts across banks
| Feature | Typical Bank | Online Bank | Credit Union |
|---|---|---|---|
| Interest rate | 0.01% to 0.10% | 0.40% to 0.60% | 0.10% to 0.50% |
| Minimum balance | $2,500 to $25,000 | $0 to $10,000 | $500 to $5,000 |
| Monthly fee | $10 to $25 | $0 to $10 | $5 to $15 |
| Debit card | Yes | Yes | Yes |
| Checks | Yes | Yes | Yes |
Online banks typically offer higher interest rates than brick-and-mortar banks because they have lower overhead costs. Credit unions often fall in the middle and may offer better rates to members who also have a checking account or direct deposit with them. Rates change frequently, so compare current offers from at least three institutions before opening. Use the bank's website or call their customer service line to confirm the rate you would receive based on your opening balance.
When a money market account makes sense
A money market account works well if you have $10,000 or more sitting in a regular checking account earning nothing, and you want that money to earn interest without moving it to a separate savings account. It also makes sense if you need to write occasional checks from a large balance — for example, if you run a small business and keep operating funds in one account.
A money market account does not make sense if you cannot maintain the minimum balance, if you make frequent withdrawals, or if you want the highest possible interest rate. In those cases, a high-yield savings account, a regular checking account, or a combination of both will serve you better. Some people also avoid money market accounts because the interest earned is small compared to the hassle of managing a separate account — if you have $5,000 in a money market account earning 0.05%, you make about $2.50 per year.
How to open and manage a money market account
To open a money market account, visit the bank's website or branch with a government ID and proof of address (a recent utility bill or lease works). You will need to fund the account with at least the minimum balance, usually by transferring from another bank account or depositing a check. The account opens within one to three business days.
Once open, monitor your balance to stay above the minimum and avoid fees. Set up alerts if the bank offers them so you know when you are close to the limit. Review your statement monthly to confirm the interest rate you are receiving matches what the bank promised. If rates rise and your bank does not increase yours, or if a competitor offers significantly more, you can move your money — there is no penalty for closing a money market account.
Frequently Asked Questions
Can I use a money market account as my main checking account?
Yes, you can use it for daily spending with the debit card and checks. However, if the bank limits withdrawals to six per month and you exceed that, you will face fees. Most people use a money market account as a secondary account for a large balance, not their primary checking account.
What happens to my interest if I fall below the minimum balance?
The bank will either charge a monthly fee (usually $10 to $25), drop your interest rate to nearly zero, or close the account. Check your account agreement to see which applies. If you know you will fall below the minimum temporarily, call the bank and ask if they will waive the fee.
Is the interest I earn on a money market account taxable?
Yes. The bank will send you a 1099-INT form at the end of the year if you earned $10 or more in interest. You report this as income on your tax return. The interest is usually small, but it still counts.
Can I move money between my checking and money market account without penalty?
Transfers between your own accounts at the same bank usually do not count toward the withdrawal limit and have no fee. Transfers to accounts at other banks do count as withdrawals. Check your bank's rules to be sure.
How does a money market account differ from a money market fund?
A money market account is a bank product insured by the FDIC up to $250,000. A money market fund is an investment product sold by brokerages and mutual fund companies, not insured by the FDIC, and carries more risk. They are different products despite the similar name.
