A money market account is a hybrid: it has features of both checking and savings, 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. However, the rules that govern it are stricter than either one alone, and the way your bank treats it for insurance purposes is different too.

The key distinction is that money market accounts are regulated under Regulation M, a Federal Reserve rule that limits how many times per month you can withdraw money or transfer it out. Most banks cap this at six transactions per month. Checking accounts have no such limit. Savings accounts technically do, but the limit is rarely enforced the way it is for money market accounts.

For deposit insurance purposes, the Federal Deposit Insurance Corporation (FDIC) treats a money market account as a separate category from both checking and savings. This means if you have $250,000 in a checking account, $250,000 in a savings account, and $250,000 in a money market account at the same bank, all three are insured up to $250,000 each—they do not share a single $250,000 pool.

Key Takeaways

  • Money market accounts earn interest and allow check-writing and debit card use, combining features of savings and checking accounts.
  • Federal rules limit you to six withdrawals or transfers per month from a money market account, a restriction that does not apply to checking accounts.
  • The FDIC insures money market accounts separately from checking and savings accounts, so you get three distinct $250,000 insurance limits at the same bank.
  • Interest rates on money market accounts are typically higher than savings accounts but lower than certificates of deposit (CDs).
  • If you exceed the six-transaction limit, your bank may charge a fee, close the account, or convert it to a checking account.

How the transaction limit actually works in practice

The six-transaction limit applies to withdrawals and transfers out of the account. Deposits into the account do not count. Transfers between your own accounts at the same bank usually count as one transaction, even if you move money multiple times in a single day.

The limit resets on a monthly cycle set by your bank—often the calendar month, but sometimes a rolling 30-day period. If you hit the limit before the month ends, you cannot withdraw or transfer money out until the new cycle begins. Some banks will reject the transaction outright. Others will charge a fee (typically $10 to $25 per excess transaction). A few will convert your account to a checking account if you repeatedly violate the limit.

This rule exists because money market accounts are designed for people who want to earn interest on money they do not need to access frequently. If you find yourself bumping against the limit regularly, a checking account or a high-yield savings account with no withdrawal restrictions may be a better fit.

When a money market account makes sense for your money

Money market accounts work well if you have a chunk of money you want to keep liquid—meaning you can access it quickly if you need it—but you do not plan to touch it often. The interest rate is usually higher than a regular savings account, though lower than a CD. You get check-writing and debit card access, so you are not completely locked out if an emergency happens.

They are also useful if you want to organize your money by purpose. You might keep your emergency fund in a money market account, your everyday spending money in a checking account, and your long-term savings in a CD or investment account. The FDIC insurance separation means each account is protected independently.

Money market accounts are less useful if you make frequent transfers, pay bills from multiple accounts, or need to move money in and out regularly. In those cases, a checking account or a high-yield savings account without withdrawal limits will cost you less in fees and give you more flexibility.

How interest rates and minimum balances differ

Money market accounts typically offer interest rates that track with the federal funds rate. When the Federal Reserve raises rates, money market rates rise. When rates fall, so do money market rates. The exact rate your bank offers depends on the bank, the amount you deposit, and current market conditions.

Most banks require a minimum balance to open a money market account—often $2,500 to $10,000, though some online banks have lower minimums or none at all. If your balance falls below the minimum, the bank may charge a monthly fee or close the account. Some banks also offer tiered rates: a higher rate if you maintain a larger balance, a lower rate if you keep less.

Checking accounts rarely earn interest at all, or they earn a very small amount. Savings accounts earn interest but usually at a lower rate than money market accounts. CDs earn more than money market accounts but lock your money away for a fixed term—you cannot access it without paying an early withdrawal penalty.

What happens if you need to move money frequently

If you regularly exceed the six-transaction limit, your bank has several options. It can charge you a fee per excess transaction. It can refuse the transaction and return it unpaid. It can close the account and return your money. Or it can convert the account to a checking account, which removes the transaction limit but may also remove the interest rate.

Before opening a money market account, ask your bank what happens if you go over the limit. Some banks are lenient and only charge a fee. Others are strict and will close the account. Knowing the policy in advance prevents surprises.

If you find that you need more than six transactions per month, switch to a checking account or a high-yield savings account with no withdrawal restrictions. The interest rate difference is usually small enough that the convenience and lack of fees make up for it.

Money market accounts versus money market funds

Do not confuse a money market account (a bank product) with a money market fund (an investment product). A money market account is a bank deposit account insured by the FDIC up to $250,000. A money market fund is a mutual fund that invests in short-term debt securities and is not FDIC-insured. If the fund loses value, you lose money. If your bank fails, your money market account is protected.

Money market funds are offered by investment firms and brokerage houses, not banks. They are not the same thing as money market accounts, even though the names are similar. When you open an account at a bank, you are getting a money market account. When you buy a fund through a brokerage, you are getting a money market fund.

Frequently Asked Questions

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

Yes, most banks issue a debit card for money market accounts. However, each debit card transaction counts toward your six-transaction limit. If you use the card frequently, you will hit the limit quickly and may face fees or account closure.

Do I pay taxes on money market account interest?

Yes. Interest earned on a money market account is taxable income. Your 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 on your tax return.

What if my bank converts my money market account to checking?

You will lose the interest rate and the account will function like a regular checking account. You may also lose any perks tied to the money market account. Contact your bank immediately if this happens and ask whether you can switch back or open a new money market account.

Is a money market account safe if the bank fails?

Yes. The FDIC insures money market accounts up to $250,000 per depositor, per bank. If your bank fails, the FDIC will return your money up to that limit. This protection is the same as for checking and savings accounts.

Can I write checks from a money market account?

Most money market accounts come with check-writing privileges, though some banks limit the number of checks you can write per month or require a minimum check amount. Ask your bank about their specific check-writing policy before you open the account.
