A money market account is a savings account that pays higher interest than a regular savings account, but requires you to keep a minimum balance and limits how often you can withdraw

Money market accounts sit between a regular savings account and a certificate of deposit (CD). Your bank or credit union holds your money, pays you interest on it, and lets you withdraw when you need to—but the tradeoff is that you have to keep a certain amount in there at all times, and you can only make a limited number of withdrawals per month before fees kick in.

The interest rate is higher than a standard savings account because the bank uses your money to buy short-term debt securities (like Treasury bills and commercial paper). You benefit from that higher rate, but you lose some of the flexibility you'd have with a regular account. If you need to access your money frequently, a money market account will cost you in fees or lost interest.

Key Takeaways

  • Money market accounts pay more interest than regular savings accounts because banks invest your deposits in short-term securities.
  • Most money market accounts require a minimum balance—often $2,500 to $25,000 depending on the bank—or you pay a monthly fee.
  • You can usually make three to six withdrawals per month before the bank charges you a fee or converts the account to a regular savings account.
  • The interest rate on money market accounts changes with market conditions, so your earnings will go up and down over time.
  • Money market accounts are FDIC-insured up to $250,000 per depositor per bank, so your principal is protected even if the bank fails.

How the interest rate works and why it changes

The interest rate on a money market account is variable, meaning it moves with the Federal Reserve's interest rate decisions. When the Fed raises rates, your money market rate typically goes up within a few weeks. When the Fed cuts rates, your rate drops. This is different from a CD, where your rate is locked in for the entire term.

Banks set their own rates within this environment, so two banks offering money market accounts may have different rates even on the same day. The rate you see advertised is what new deposits earn; existing balances sometimes earn a lower rate. Always check the fine print to see whether the advertised rate applies to your whole balance or just new money.

Because rates change, a money market account makes sense when you expect interest rates to stay high or rise further. If rates are falling, the advantage shrinks—your earnings will decline along with the rate.

Minimum balance requirements and monthly fees

Most banks require you to keep a minimum balance in the account at all times. This minimum varies widely: some online banks have no minimum, while others require $2,500, $10,000, or even $25,000. If your balance drops below the minimum, the bank charges a monthly fee (usually $10 to $25) or converts the account to a regular savings account with a lower rate.

The minimum exists because the bank needs a certain amount of money to invest in those short-term securities. Smaller balances don't generate enough return to justify the higher interest rate they're paying you. Before opening an account, confirm the minimum and whether it applies to your total balance or just your average balance over the month.

Some banks waive the minimum if you set up automatic monthly deposits or maintain a linked checking account with them. Ask about these options if the stated minimum is higher than you can comfortably keep.

Withdrawal limits and what happens when you exceed them

Federal rules allow you to make up to six withdrawals per month from a money market account (including transfers out, but not ATM withdrawals or in-person withdrawals at a branch). If you exceed this limit, the bank can charge you a fee—typically $10 to $25 per excess withdrawal—or close the account and move your money to a regular savings account.

This limit exists because money market accounts are technically savings accounts, and the Fed caps withdrawals to discourage frequent trading. In practice, most people don't hit this limit because they're not using the account for everyday spending. If you need to withdraw more than six times a month, a regular savings account or checking account is a better fit.

Some banks are more lenient than others about enforcing this rule, especially if you exceed the limit only occasionally. But don't count on it—read your account agreement to see what your bank's policy is, and plan your withdrawals accordingly.

Money market accounts versus other savings options

A money market account is not the same as a money market fund, which is an investment product sold by brokerages and mutual fund companies. Money market funds are not FDIC-insured and carry more risk, even though they sound similar. Stick with a money market account at a bank or credit union if you want federal insurance protection.

Compared to a regular savings account, a money market account pays more interest but requires a higher minimum balance and limits your withdrawals. Compared to a CD, a money market account has a variable rate (so you earn less if rates fall) but lets you access your money without a penalty. Compared to a high-yield savings account, a money market account often has a higher minimum balance but similar interest rates at online banks.

The right choice depends on how much you have to save, how often you need to withdraw, and whether you want a locked-in rate or are willing to accept a variable one. If you have $10,000 or more sitting in a regular savings account earning almost nothing, a money market account or high-yield savings account will earn you more with minimal extra effort.

FDIC insurance and what it covers

Money market accounts at banks are FDIC-insured up to $250,000 per depositor per bank. This means if the bank fails, the government guarantees your money up to that limit. If you have more than $250,000, the amount over that is not protected, so you may want to split your deposits across multiple banks.

Credit unions offer similar protection through the National Credit Union Administration (NCUA), also up to $250,000 per account owner per institution. The insurance covers the principal and accrued interest, so you don't lose earnings if the institution closes.

This protection is one reason money market accounts are safer than money market funds or other investments. You're not betting on the market; you're earning a may provide rate (even though it changes) with government backing.

When a money market account makes sense for your budget

A money market account works best if you have a lump sum of money—$5,000 or more—that you want to earn interest on without locking it away in a CD. It's ideal for an emergency fund that sits untouched most months, or for saving toward a goal six to twelve months away. The higher interest rate means your money grows faster than it would in a regular savings account.

It does not work well if you need to withdraw frequently, if you have less than the minimum balance, or if you're saving for something more than a few years away (in which case investing in stocks or bonds through a brokerage might earn more). It also doesn't work if interest rates are falling and you want to lock in a rate—that's when a CD is the better choice.

Check the current rate environment before you open one. If the Fed is cutting rates, the advantage of a money market account shrinks because your rate will drop soon. If rates are stable or rising, the account makes more sense.

Frequently Asked Questions

Can I use a money market account like a checking account?

No. While some money market accounts come with a debit card or checkbook, you're limited to six withdrawals per month. If you exceed that limit, you'll face fees or the account may be converted to a regular savings account. Use a checking account for everyday spending and a money market account for money you want to earn interest on but don't need to touch often.

What happens if my balance drops below the minimum?

The bank will charge you a monthly fee (usually $10 to $25) until your balance rises back above the minimum, or it may convert your account to a regular savings account with a lower interest rate. Some banks waive the fee if you bring the balance back up within a certain period. Check your account agreement for your bank's specific policy.

Is a money market account safe if the bank fails?

Yes, up to $250,000 per depositor per bank. The FDIC insures money market accounts the same way it insures regular savings accounts. If the bank closes, you get your money back, including any interest earned. If you have more than $250,000, open accounts at different banks to keep all your money protected.

How often does the interest rate change?

The rate can change at any time, though most banks adjust it after the Federal Reserve meets (roughly every six weeks). You'll see the biggest changes when the Fed raises or cuts its benchmark rate. Some banks change rates more frequently than others, so compare rates across banks before opening an account and check periodically to see if you're still getting a competitive rate.

Can I move money from a money market account to a checking account without penalty?

Yes, but only up to six times per month. After that, you'll face a fee or the account may be converted. Transfers to another account at the same bank usually count toward this limit, so plan your moves carefully if you're near the six-withdrawal cap.
