A money market account is neither—it's a hybrid that borrows rules from both
A money market account (MMA) sits between a savings account and a checking account. It has the interest-earning power of savings, but it also lets you write checks and use a debit card like checking does. Banks classify it as a savings product for regulatory purposes, which means it's covered by the same FDIC insurance limits as a savings account (up to $250,000 per depositor, per bank). But the way you actually use it—the daily mechanics—blends features from both account types.
The catch is that money market accounts come with restrictions that pure checking accounts don't have. Federal rules limit you to six withdrawals per month (though this rule was suspended during the pandemic and some banks have not reinstated it). If you exceed the limit, the bank can charge a fee, close the account, or convert it to checking. You also typically need a higher minimum balance to open one and to avoid monthly fees.
The reason banks structure them this way is simple: they want to pay you interest on your balance, but they also want to limit how often you move money out. Savings accounts restrict withdrawals even more strictly. Checking accounts let you withdraw as much as you want but pay little or no interest. A money market account splits the difference.
Key Takeaways
- Money market accounts earn interest like savings accounts but allow check-writing and debit card access like checking accounts.
- Federal law limits you to six withdrawals per month from a money market account, though enforcement varies by bank.
- FDIC insurance treats money market accounts as savings products, covering up to $250,000 per depositor per bank.
- Minimum balance requirements and monthly fees are typically higher for money market accounts than for either savings or checking alone.
- If you need unlimited, frequent access to your money, a checking account is the right choice; if you rarely touch the balance, a savings account may offer better rates.
Why the withdrawal limit exists and what it means for you
The six-withdrawal limit comes from Federal Reserve Regulation D, which was designed to keep banks from treating savings accounts like checking accounts. The rule says that banks must limit certain types of withdrawals—specifically transfers to other accounts and checks—to six per month. In-person withdrawals at a teller window and ATM withdrawals are usually exempt, which is why the rule is confusing in practice.
In reality, many banks stopped enforcing this limit after the Federal Reserve suspended it in April 2020. Some banks have reinstated it; others have not. Before you open a money market account, call the bank and ask directly: "Do you enforce the six-withdrawal limit, and what happens if I exceed it?" The answer varies widely. Some banks charge $25 to $35 per excess withdrawal. Others convert your account to checking. A few do nothing at all.
This uncertainty is one reason money market accounts work best for people who don't need frequent access to their money. If you're building an emergency fund and you plan to touch it only a few times a year, the limit won't affect you. If you're managing cash flow for a small business or paying bills multiple times a week, a checking account is the better choice.
Interest rates: where money market accounts usually win
Money market accounts typically pay higher interest than regular savings accounts at the same bank, and far higher than checking accounts. The rate varies by bank and by how much you deposit. As of early 2024, online banks offer money market rates between 4% and 5% APY on balances of $2,500 or more, while traditional brick-and-mortar banks often pay less than 1%. Checking accounts almost never pay meaningful interest.
The tradeoff is the minimum balance. A checking account might require $500 to open. A money market account at the same bank might require $2,500 or $10,000. If your balance falls below the minimum, you'll pay a monthly fee—often $10 to $25—which wipes out any interest you earned. Read the fee schedule before you open the account.
If you're comparing a money market account to a high-yield savings account at an online bank, the interest rate is usually similar or identical. The real difference is the withdrawal limit and the check-writing feature. If you don't need to write checks, a savings account gives you the same rate with fewer restrictions.
FDIC insurance and what happens if the bank fails
Money market accounts are insured by the FDIC up to $250,000 per depositor, per bank, in the same way savings accounts are. This means if the bank fails, you won't lose your money. The insurance covers the principal and any interest that has been credited to the account.
The key word is "per bank." If you have $150,000 in a money market account at Bank A and $150,000 in a money market account at Bank B, both are fully insured. But if you have $200,000 in a money market account and $100,000 in a savings account at the same bank, only $250,000 total is insured—you lose the extra $50,000. Money market accounts and savings accounts share the same insurance bucket.
Checking accounts have their own $250,000 insurance limit, separate from savings and money market. So if you have $250,000 in checking and $250,000 in a money market account at the same bank, both are fully covered.
When to use a money market account instead of checking or savings
A money market account makes sense if you want to earn interest on money you won't touch often, but you also want the option to write checks or use a debit card without opening a second account. It's useful for a sinking fund—money you're setting aside for a specific goal like a car repair or a vacation—because you earn interest while you wait, and you can access it quickly if you need to.
It's also a reasonable choice if you have a large balance and your bank offers a tiered rate structure. Some banks pay higher interest on money market accounts than on savings accounts once you reach a certain threshold, like $50,000. If you're keeping that much liquid, the extra interest can add up.
A money market account is not the right choice if you need to make frequent transfers, pay bills online, or use your debit card regularly. Use checking for that. It's also not the right choice if you're trying to maximize interest on a small balance—the minimum balance requirement and monthly fees will eat into your earnings. Use a high-yield savings account instead.

Frequently Asked Questions
Can I use my money market account debit card as much as I want?
Yes. The six-withdrawal limit applies to transfers and checks, not to debit card purchases or ATM withdrawals. You can use the debit card as often as you need. However, some banks count ATM withdrawals toward the limit, so ask your bank specifically which transactions count.
What happens if I exceed the withdrawal limit?
It depends on the bank. Some charge $25 to $35 per excess withdrawal. Others convert your account to checking. A few do nothing. Call your bank and ask what their policy is before you open the account, because the answer is not standardized.
Is a money market account safer than a checking account?
No. Both are FDIC-insured up to $250,000. The difference is that checking accounts have a separate $250,000 insurance limit, so if you have both at the same bank, you're covered for $500,000 total. Money market and savings accounts share one $250,000 limit.
Should I move my emergency fund to a money market account?
Only if you won't need to touch it more than six times per month and your bank doesn't enforce the withdrawal limit. If you need faster, more frequent access, a high-yield savings account offers similar interest rates with no withdrawal restrictions. Check the current rates at both before deciding.
Can I write checks from a money market account like a regular checking account?
Yes, but with limits. You can usually write checks from a money market account, and those checks count toward your six-withdrawal limit. Some banks provide a checkbook; others require you to request checks. The process is slower than with a dedicated checking account, so don't use it for everyday bills.
