A money market account is a hybrid—it has features of both, but it is neither one

A money market account sits between a traditional savings account and a checking account. It earns interest like a savings account does, but it also lets you write checks and use a debit card like a checking account does. The catch is that banks limit how many times per month you can withdraw money or write checks, whereas a checking account has no such limit.

The reason for this middle ground is historical: money market accounts were created to compete with money market funds (investment accounts offered by brokerages). Banks wanted to offer something similar but with FDIC insurance. The result is an account that looks like a checking account on the surface but behaves more like a savings account in how the bank controls your access to the money.

Key Takeaways

  • Money market accounts earn interest, which checking accounts typically do not, but they limit your withdrawals per month while checking accounts do not.
  • You can write checks and use a debit card on most money market accounts, making them feel like checking accounts despite the withdrawal restrictions.
  • The withdrawal limit exists because banks use your deposits to invest in short-term securities, so they need to control how quickly money leaves the account.
  • If you need unlimited access to your money, a checking account is the better choice; if you rarely need to withdraw, a money market account pays more interest.

How the withdrawal limit actually works

Federal rules once capped money market withdrawals at six per month. That rule was suspended during the pandemic and has not been reinstated, so the limit now depends on your bank. Some banks have removed the limit entirely; others keep it at six; some set it lower or higher. You need to check your account agreement or call your bank to know the exact number.

The limit usually applies to all withdrawals combined—checks written, debit card transactions, transfers out, and ATM withdrawals all count toward the same monthly total. If you hit the limit, the bank can refuse the transaction, charge a fee, or convert your account to a checking account. This is why money market accounts work best for people who want to save money and leave it alone, not for people who need frequent access.

Why money market accounts pay more interest

Banks pay higher interest on money market accounts because they know the money will stay in the account longer. When you deposit money in a checking account, the bank expects you to spend it soon. When you deposit money in a money market account, the withdrawal limit signals that you plan to keep it there, so the bank can lend it out or invest it in longer-term securities and keep the extra profit.

The interest rate varies by bank and by how much money you have in the account. Some banks pay a higher rate only if your balance exceeds a certain threshold—say, $10,000 or $25,000. Others pay the same rate regardless of balance. Interest rates also change over time as the Federal Reserve adjusts its rates, so the rate you see today may be different in three months.

When a money market account makes sense

A money market account is useful if you have money you want to keep separate from your everyday spending but you do not want to lock it away in a certificate of deposit (CD) or other product with an early withdrawal penalty. It is also useful if you occasionally need to write a check from savings—for example, to pay a large bill—but you do not want a full checking account.

Money market accounts also work well as an emergency fund. You can access the money if you truly need it, but the withdrawal limit discourages you from dipping into it for small expenses. The interest you earn helps your savings grow slightly faster than it would in a regular savings account.

When a checking account is the better choice

If you need to write checks regularly, pay bills online, or use your debit card multiple times per week, a checking account is what you need. Checking accounts have no withdrawal limit and are designed for frequent transactions. Most checking accounts pay no interest, but some banks now offer checking accounts with interest rates that rival money market accounts—though usually only if you meet certain conditions like setting up direct deposit or maintaining a high balance.

If you have both a checking account and a money market account, you can use them together: keep your everyday spending money in checking and your savings in the money market account. This way you earn interest on the money you are not spending while keeping easy access to the money you are.

The difference in FDIC insurance

Both checking and money market accounts are insured by the FDIC up to $250,000 per account holder per bank. If the bank fails, you do not lose your money. The insurance limit is the same whether you have a checking account, a savings account, or a money market account, so this is not a reason to choose one over the other.

If you have multiple accounts at the same bank, the $250,000 limit applies to each account type separately. So you could have $250,000 in a checking account and $250,000 in a money market account at the same bank and both would be fully insured. The key is that they are different account types; two checking accounts at the same bank would share the same $250,000 limit.

How to decide which account type fits your situation

Ask yourself three questions: How often do you need to access this money? Do you want to earn interest? Can you live with a withdrawal limit?

If you access the money more than six times per month, choose checking. If you access it fewer than six times per month and want to earn interest, choose a money market account. If you want to earn interest but also need frequent access, look for a checking account that pays interest—they exist, though the rates are usually lower than money market accounts.

You do not have to choose one or the other. Many people have both: a checking account for bills and daily spending, and a money market account or savings account for money they want to keep separate and grow.

Frequently Asked Questions

Can I use a debit card on a money market account?

Most banks issue a debit card with money market accounts, but the card is subject to the same withdrawal limit as checks and transfers. If your limit is six withdrawals per month, using the debit card counts toward that total. Some banks do not issue debit cards for money market accounts at all, so ask before you open one.

What happens if I exceed the withdrawal limit?

The bank can refuse the transaction, charge a fee (usually $10 to $25 per excess withdrawal), or close the account and move your money to a checking account. The exact consequence depends on your bank's policy, which should be in your account agreement. If you find yourself hitting the limit regularly, a checking account may be a better fit.

Do money market accounts have monthly fees?

Some do and some do not. Fees vary by bank and often depend on your balance or whether you set up direct deposit. Common fees range from $5 to $15 per month. Always check the fee schedule before opening an account, because a high fee can wipe out the interest you earn.

Can I transfer money from a money market account to a checking account?

Yes, but the transfer counts as a withdrawal and counts toward your monthly limit. If you need to move money between your own accounts frequently, a money market account is not the right tool. A regular savings account with no withdrawal limit might work better.

Is a money market account the same as a money market fund?

No. A money market account is a bank product insured by the FDIC. A money market fund is an investment product sold by brokerages and mutual fund companies, and it is not insured by the FDIC. Money market funds can lose value, though the risk is usually very low. Money market accounts cannot lose value.
