A money market account is a hybrid that acts like both, but leans savings
A money market account (MMA) is technically a savings account under federal banking rules, but it functions more like a checking account than a traditional savings account does. You get a debit card and check-writing ability—features you'd expect from checking—but the account is regulated as savings, which means the bank can limit how many withdrawals you make per month and can require advance notice before you pull out large sums.
The confusion exists because money market accounts sit in the middle. They're not checking accounts, so don't expect unlimited transactions. They're not savings accounts in the old sense, so you won't be locked into a passbook or forced to wait days to access your money. What you get instead is a middle ground: modest interest, transaction flexibility, and higher minimum balances than either checking or savings alone.
The practical difference matters when you're deciding where to put money you might need soon. If you need to write checks or swipe a card constantly, checking is faster. If you want the highest interest rate and don't mind waiting to move money, a savings account or CD is better. A money market account works if you want both access and a rate that beats checking, and you can live with the withdrawal limits.
Key Takeaways
- Money market accounts are classified as savings accounts by federal law, but they come with debit cards and check-writing privileges that savings accounts typically don't offer.
- Banks can limit you to six withdrawals per month (or fewer) on a money market account, whereas checking accounts have no withdrawal limit.
- Money market accounts usually require a higher minimum balance than checking or savings accounts, often $2,500 to $10,000 depending on the bank.
- Interest rates on money market accounts are higher than checking but typically lower than dedicated savings accounts or money market funds.
- The account type you choose depends on how often you need to access the money and whether you prioritize transaction frequency or interest earnings.
How the withdrawal limit works in practice
Federal Regulation D historically capped withdrawals on savings accounts at six per month. Money market accounts fall under this same rule, even though they look and feel like checking accounts. That means you can make six withdrawals or transfers out of the account each month—whether by debit card, check, ACH transfer, or wire—before the bank can charge you a fee or convert the account to checking.
In practice, most banks don't enforce this strictly anymore, especially after the Federal Reserve suspended the rule in 2020. Many banks have kept the suspension in place, so you may find you can withdraw more than six times without penalty. However, the rule is still on the books, and banks can reinstate enforcement at any time. If you're planning to use the account for frequent transactions, call the bank and ask their current policy rather than assuming the limit doesn't apply.
Checking accounts have no such limit. You can write 50 checks a month or make 100 debit card transactions without triggering any restriction. If transaction frequency is your priority, checking is the safer choice.
Interest rates: why money market accounts sit in the middle
A money market account pays interest, but the rate varies by bank and by how much money you keep in the account. Most banks tier their rates—the more you deposit, the higher the rate you earn. A bank might offer 0.01% on balances under $10,000 and 4.50% on balances over $100,000, for example. The rates change frequently and vary widely between institutions.
Checking accounts almost never pay interest, or they pay a rate so low (0.01%) that it's essentially zero. Savings accounts and money market accounts both pay interest, but money market rates are often lower than high-yield savings accounts at online banks. The tradeoff is that money market accounts give you check-writing and debit card access, while a high-yield savings account might not. If you want the highest rate and don't need to write checks, a dedicated savings account often wins.
The minimum balance requirement is where the interest rate matters most. If your bank requires $5,000 to open a money market account and only pays 1.50% on balances under $25,000, you're earning about $75 a year on that $5,000. That's real money, but it's also why comparing rates across banks before you open the account is worth your time.
Minimum balance requirements and fees
Money market accounts require higher minimum balances than checking or traditional savings accounts. Most banks ask for $2,500 to $10,000 to open one, and some require $25,000 or more. If your balance drops below the minimum, the bank may charge a monthly fee ($10 to $25 is common) or close the account.
Checking accounts typically require $300 to $1,000 to open, and many online banks have no minimum at all. Savings accounts often have no minimum or ask for just $100. If you don't have several thousand dollars to park in one account, a money market account may not be practical for you.
Some banks waive the minimum if you set up direct deposit or maintain a linked checking account with them. Ask about these options when you're comparing banks, because a waived minimum can make a money market account worth opening even if you're not at the threshold yet.
When to use a money market account instead of checking or savings
A money market account makes sense if you have money you want to earn interest on, but you also want the flexibility to access it without waiting. You might use it for an emergency fund, a down payment you're saving for over the next year, or money you're setting aside for a large purchase. You get better interest than checking, more access than a CD, and check-writing ability if you need it.
It's less useful if you're living paycheck to paycheck and need to move money in and out constantly. The withdrawal limits and minimum balance requirements will frustrate you, and you'll be better served by a checking account. It's also less useful if you have a large sum you don't plan to touch for years—a CD or money market fund will pay more interest.
The sweet spot is having $5,000 to $50,000 that you want to keep accessible but earning interest, and you can live with making no more than six withdrawals per month. If that describes your situation, a money market account bridges the gap between checking and savings better than either one alone.
How money market accounts differ from money market funds
Don't confuse a money market account (a bank product) with a money market fund (an investment product). A money market account is FDIC-insured up to $250,000, meaning your money is protected if the bank fails. A money market fund is not insured—it's an investment in short-term debt securities, and its value can fluctuate. Money market funds usually pay higher interest than money market accounts, but they carry investment risk.
If you want may provide safety and FDIC protection, use a money market account at a bank. If you're willing to accept investment risk in exchange for potentially higher returns, a money market fund through a brokerage might be worth exploring. Most people starting out should stick with the bank version unless they have a specific reason to invest.
Comparing money market accounts to your other options
| Account Type | Debit Card / Checks | Withdrawal Limit | Typical Interest Rate | Minimum Balance | FDIC Insured |
|---|---|---|---|---|---|
| Checking | Yes | Unlimited | 0% to 0.01% | $0 to $1,000 | Yes |
| Savings | No | 6 per month | 0.01% to 5.35% | $0 to $500 | Yes |
| Money Market Account | Yes | 6 per month | 0.01% to 5.00% | $2,500 to $25,000 | Yes |
| Certificate of Deposit (CD) | No | None (locked term) | 4.00% to 5.50% | $500 to $2,500 | Yes |
The table shows why the choice depends on your situation. If you need unlimited access and don't care about interest, checking wins. If you want the highest rate and can lock money away for months or years, a CD is better. If you want both access and interest, and you have the minimum balance, a money market account splits the difference.
Frequently Asked Questions
Can I use a money market account as my main checking account?
Technically yes, but it's not ideal. You'll hit the six-withdrawal limit quickly if you're making regular purchases, and the bank can charge you for exceeding it. Use a money market account for money you want to earn interest on and access occasionally, and keep a separate checking account for daily spending.
What happens if I exceed the six withdrawals per month?
The bank can charge a fee (usually $10 to $25 per excess withdrawal) or convert your account to a checking account, which typically pays no interest. Some banks don't enforce the limit anymore, but you shouldn't count on that. If you need more than six withdrawals, ask the bank about their policy before you open the account.
Is a money market account safer than a savings account?
Both are equally safe if they're at an FDIC-insured bank. Your money is protected up to $250,000 in either account if the bank fails. The difference is access and interest rate, not safety. Check that the bank displays the FDIC logo on its website to confirm coverage.
Should I move my emergency fund to a money market account?
If your emergency fund is large enough to meet the minimum balance and you don't need to withdraw from it more than six times a month, a money market account will earn you more interest than a checking account. However, a high-yield savings account with no minimum and no withdrawal limits might be a better choice for an emergency fund, even if the rate is slightly lower.
Can I write checks from a money market account?
Most money market accounts come with check-writing privileges, but the number of checks you can write per month is usually limited to the same six-withdrawal cap. Some banks allow unlimited check-writing but count other withdrawals against the limit. Confirm the bank's policy before you open the account if check-writing is important to you.
