Money market accounts blend checking and savings features, but they are legally classified as savings accounts

A money market account is a savings account, not a checking account, according to federal banking rules. But it functions like a hybrid: it earns interest like a savings account, but it comes with a debit card and check-writing ability like a checking account. The catch is that federal law limits how many withdrawals you can make per month—a restriction that does not explore to checking accounts.

The reason for this classification matters. Banks are required to hold more cash reserves against checking accounts than savings accounts. By law, money market accounts must follow savings account withdrawal limits, even though they look and feel partly like checking accounts. This is why your bank might decline a withdrawal or charge a fee if you exceed the monthly limit, even though you have a debit card attached to the account.

The practical difference comes down to how you actually use the account. If you need to make unlimited transactions every month, a checking account is the right tool. If you want to earn interest while keeping some withdrawal flexibility, a money market account works. But you cannot treat it like a checking account without hitting limits.

Key Takeaways

  • Money market accounts are legally savings accounts, which means they are subject to federal withdrawal limits even though they have debit cards and check-writing features.
  • Federal law historically limited money market account withdrawals to six per month, though this rule was suspended in 2020 and banks now set their own limits—typically between six and ten per month.
  • A checking account has no federal withdrawal limit, making it the only account type designed for unlimited monthly transactions.
  • Most money market accounts pay higher interest rates than checking accounts because banks expect fewer transactions and can lend out more of the deposited money.

How the withdrawal limit actually works

The federal withdrawal limit on savings accounts (including money market accounts) was originally set at six per month. In April 2020, the Federal Reserve suspended this rule in response to the pandemic, and it has not been reinstated. However, banks are now allowed to set their own limits, and most have chosen to keep limits in place—typically between six and ten withdrawals per month.

What counts as a withdrawal varies by bank. A debit card transaction usually counts. A check you write counts. An ACH transfer out of the account counts. A wire transfer counts. But transfers between your own accounts at the same bank often do not count, and deposits never count against the limit.

If you exceed your bank's limit, you will typically face a fee—usually between $10 and $25 per excess withdrawal. Some banks will straightforward decline the transaction instead. This is why money market accounts work best for people who need occasional access to their money but do not make frequent withdrawals.

Why banks structure money market accounts this way

Banks offer higher interest rates on money market accounts than on checking accounts because they expect you to leave the money alone. When you make fewer withdrawals, the bank can lend out more of the deposited funds for longer periods, which generates more profit for the bank. That profit gets passed back to you as interest.

A checking account, by contrast, is designed for constant movement. You deposit paychecks, write checks, use your debit card, set up automatic bill payments. The bank cannot count on that money staying put, so it cannot lend it out as aggressively. The trade-off is that you get unlimited transactions and no interest (or minimal interest) in return.

Money market accounts sit in the middle: you get some interest, some transaction flexibility, but not unlimited transactions. The account type exists because many people want to earn a return on their money without locking it away in a certificate of deposit or savings account with no debit card.

When a money market account makes sense versus a checking account

Choose a money market account if you have a primary checking account elsewhere and want to park extra money somewhere that earns interest while staying accessible. For example, you might keep your emergency fund in a money market account at one bank and your daily spending account at another. You would not make frequent withdrawals from the emergency fund, so the withdrawal limit does not affect you.

Choose a checking account if you need to make unlimited transactions—if you are paying bills, receiving direct deposits, writing checks, or using your debit card regularly. A checking account is the only account type with no transaction limits, and most checking accounts now come with no monthly fee if you meet a minimum balance or set up direct deposit.

Some people try to use a money market account as their primary account and run into problems when they hit the withdrawal limit mid-month. That is a sign the account type is wrong for their spending pattern. The account is designed as a secondary account, not a primary one.

Interest rates and fees: what you actually pay or earn

Money market account interest rates vary widely depending on the bank and the current interest rate environment. As of early 2024, rates at online banks range from around 4% to 5% annual percentage yield (APY), while rates at traditional brick-and-mortar banks are often lower—sometimes under 1%. The rate your bank offers depends on what the Federal Reserve has set as its benchmark rate and how much competition the bank faces for deposits.

Fees on money market accounts typically include a monthly maintenance fee (usually $0 to $15, often waived if you maintain a minimum balance), excess withdrawal fees ($10 to $25 per transaction over the limit), and overdraft fees if you somehow overdraw the account. Some banks charge a fee to close the account if you do so within a certain period.

Checking accounts often have no monthly fee but may charge overdraft fees and out-of-network ATM fees. The total cost depends on how you use the account. If you make frequent withdrawals from a money market account, the excess withdrawal fees will add up quickly and make the account more expensive than a checking account, even if the interest rate is higher.

The difference in how banks report these accounts

On your tax forms and credit reports, a money market account shows up as a savings account, not a checking account. This matters if you are explore for credit, because lenders sometimes look at what types of accounts you hold. A checking account is seen as an indicator of financial stability and regular income. A savings account (including a money market account) is seen as an indicator that you have money set aside.

For tax purposes, interest earned in a money market account is reported on a 1099-INT form, just like interest from any other savings account. The bank will send you this form if you earned more than $10 in interest during the year. You report this interest as income on your tax return.

Frequently Asked Questions

Can I use a money market account as my main checking account?

Technically yes, but it is not recommended. If you make more than six to ten withdrawals per month (depending on your bank's limit), you will face fees or declined transactions. Most people who try this end up switching to a checking account within a few months because the withdrawal limit becomes frustrating.

Do money market accounts have FDIC protection?

Yes. Money market accounts at FDIC-insured banks are covered up to $250,000 per depositor, per bank, just like checking and savings accounts. This protection applies regardless of whether the account is classified as a checking or savings account.

What happens if I exceed the withdrawal limit?

Your bank will either charge you a fee (usually $10 to $25 per excess withdrawal) or decline the transaction. Some banks do both—they decline the first excess withdrawal and charge a fee if you try again. Check your account agreement to see your bank's specific policy.

Can I write checks from a money market account?

Most money market accounts come with check-writing ability, but the checks count against your monthly withdrawal limit. If you write five checks and make one debit card transaction, you have used six of your six allowed withdrawals for the month. This is why money market accounts are not ideal for people who write checks regularly.

Why would I choose a money market account over a high-yield savings account?

The main reason is access. A high-yield savings account typically has no debit card and no check-writing ability—you can only withdraw money by transferring it to another account or requesting a check from the bank. A money market account gives you a debit card and checks, so you can access your money more quickly if you need it.
