A money market account is a hybrid savings product that sits between a regular savings account and a money market fund

A money market account is a bank or credit union deposit account that combines features of both checking and savings accounts. You can write checks or use a debit card to withdraw money, but the account pays interest based on short-term debt instruments—Treasury bills, commercial paper, and other very short-term loans. The interest rate moves with market conditions, which is why it's called a "money market" account rather than a fixed-rate savings account.

The account is FDIC-insured at banks (up to $250,000 per depositor) or NCUA-insured at credit unions, so your principal is protected even if the institution fails. The tradeoff is that you typically need a higher minimum balance than a regular savings account—often $2,500 to $25,000 depending on the bank—and the account comes with limits on how many withdrawals you can make per month.

Money market accounts are not the same as money market funds, which are investment products sold by brokerages and mutual fund companies. Those funds are not FDIC-insured and their value can fluctuate. This guide covers only bank and credit union money market accounts.

Key Takeaways

  • Money market accounts pay interest that changes with market rates, so your earnings go up when the Federal Reserve raises rates and down when it cuts them.
  • You can write checks or withdraw money using a debit card, but federal rules limit you to six withdrawals per month (though many banks have relaxed this during low-rate periods).
  • The minimum balance required to open and maintain the account varies widely—some banks ask for $2,500, others for $25,000 or more—and you may lose the advertised rate if your balance drops below that threshold.
  • Your deposits are insured by the FDIC (at banks) or NCUA (at credit unions) up to $250,000, so the account is safer than keeping cash at home or in an uninsured investment.

How the interest rate is set and when it changes

The interest rate on a money market account is not fixed for a year or five years the way a CD rate is. Instead, the bank sets the rate based on what it earns from short-term lending—primarily Treasury bills and commercial paper—and adjusts it whenever market conditions shift. When the Federal Reserve raises its benchmark interest rate, banks typically raise money market rates within days or weeks. When the Fed cuts rates, money market rates fall.

The bank is not obligated to pass along every rate change to you. Some banks move rates quickly and transparently; others lag behind or raise rates slowly while cutting them faster. The only way to know whether you are getting a competitive rate is to compare what your current bank is paying against what other banks are offering. Rate comparison sites and bank websites show current rates, though you should call the bank directly to confirm the rate applies to your balance level.

During periods when the Federal Reserve keeps rates very low (as it did from 2008 to 2015 and again from 2020 to 2022), money market accounts may pay less than 0.01% annually. During periods of higher rates, the same account might pay 4% to 5%. The difference between a 0.01% account and a 5% account on a $10,000 balance is roughly $500 per year, so shopping for rate matters.

Withdrawal limits and how they work in practice

Federal Regulation D historically limited money market accounts to six withdrawals per month, with penalties for exceeding the limit. During the pandemic, the Federal Reserve suspended this rule, and many banks have not reinstated it. Some banks still enforce the limit; others have removed it entirely. Before opening an account, check the bank's disclosure document or call to ask whether withdrawal limits explore.

The limit applies to transfers and checks written from the account, not to ATM withdrawals at the bank's own machines. So you might be able to withdraw cash from an ATM without counting against the limit, but transferring money to another bank account or writing a check would. The rules vary by bank, so read the account agreement carefully.

If you exceed the limit, the bank may charge a fee (typically $25 to $35 per excess withdrawal) or convert your account to a regular savings account, which pays a lower rate. Some banks straightforward refuse the withdrawal. The practical effect is that money market accounts work best for people who need occasional access to their money but do not plan to move it in and out frequently.

Minimum balance requirements and what happens if you fall short

Money market accounts require a higher opening balance than most savings accounts. The minimum varies by bank and by account tier within the same bank. A basic money market account might require $2,500; a premium version at the same bank might require $25,000 or $100,000. Some online banks have no minimum at all, though they may pay a lower rate.

If your balance drops below the minimum, the bank may charge a monthly fee (typically $10 to $25) or reduce your interest rate to a much lower tier. Some banks do both. A few banks will close the account if the balance stays below the minimum for a set period. Check the account agreement to see what happens at your specific bank.

The minimum balance is usually calculated as a daily balance or an average monthly balance. If you dip below the minimum for even one day, some banks will charge the fee or drop the rate for that entire month. Others use an average, so a temporary dip does not trigger a penalty. This detail matters if you are managing cash flow tightly.

Money market accounts versus savings accounts and CDs

A regular savings account typically requires a lower minimum balance (often $0 to $500), pays a fixed rate set by the bank, and has no withdrawal limits. The tradeoff is that the rate is usually lower than a money market account rate during periods of rising interest rates, because the bank locks in a fixed rate and does not benefit from rate increases. During periods of falling rates, a fixed savings account rate may look better in hindsight.

A certificate of deposit (CD) locks your money for a set term—three months, one year, five years—and pays a fixed rate. If you withdraw before the term ends, you pay a penalty (typically three to six months of interest). CDs usually pay more than money market accounts during normal conditions, because you are giving up access to your money. Money market accounts are better if you want the option to withdraw without penalty.

A money market account is better than a savings account if you want a higher rate and do not mind the higher minimum balance and withdrawal limits. It is worse than a CD if you know you will not need the money for a set period and want to lock in a higher rate. The choice depends on your timeline and how often you expect to access the money.

How money market accounts fit into a savings strategy

Money market accounts work best as a holding place for money you want to keep safe and earning interest, but might need to access within a few months. Examples include an emergency fund, money saved for a down payment on a home or car, or a buffer for irregular expenses like car insurance or property taxes.

Because the rate moves with market conditions, money market accounts are not a good choice if you are trying to lock in a specific return. If rates are currently 5% and you believe they will fall, a CD lets you lock in the 5% for a year or more. If you put the money in a money market account and rates fall to 2%, your earnings drop with them.

Money market accounts are also not a substitute for a checking account. The withdrawal limits and minimum balance requirements make them inconvenient for everyday spending. Use a checking account for bills and regular expenses, and a money market account for money you are setting aside.

FDIC insurance and what it covers

Money market accounts at banks are covered by FDIC insurance up to $250,000 per depositor, per bank. This means if the bank fails, the FDIC will reimburse you for the full balance up to $250,000. If you have $300,000 in a money market account at one bank, the FDIC covers $250,000 and you lose $50,000.

The $250,000 limit applies to all deposit accounts you hold at the same bank combined—checking, savings, money market, and CDs all count toward the same limit. If you have $150,000 in a money market account and $150,000 in a savings account at the same bank, you have $300,000 total, and only $250,000 is insured. The extra $50,000 is not covered.

If you have more than $250,000 to deposit, you can open accounts at multiple banks to increase your coverage. Each bank's accounts are insured separately up to $250,000. At credit unions, the equivalent protection is NCUA insurance, which also covers up to $250,000 per depositor per institution.

Frequently Asked Questions

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

You can write checks and use a debit card, but federal rules limit withdrawals to six per month at most banks (though some have removed this limit). For everyday spending, a checking account is more practical because it has no withdrawal limits and usually no minimum balance.

What happens to my money market rate if the Federal Reserve cuts interest rates?

Your rate will fall, usually within days or weeks. The bank adjusts rates based on what it earns from short-term lending, which moves with Fed rate changes. You can move your money to a different bank if the rate becomes uncompetitive, though you may face a delay in accessing funds during the transfer.

Is a money market account safe if the bank fails?

Yes, up to $250,000. The FDIC insures deposits at banks, and the NCUA insures deposits at credit unions. If the institution fails, you will be reimbursed in full up to the limit. Amounts above $250,000 are not protected.

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

During normal market conditions, the rates are similar. The main difference is that money market accounts let you write checks and use a debit card, while savings accounts typically do not. If you need check-writing ability and do not mind the withdrawal limits, a money market account offers that flexibility.

Do I pay taxes on money market account interest?

Yes. The interest you earn is taxable income. The bank will send you a 1099-INT form at the end of the year showing how much interest you earned, and you report that on your tax return. The interest is taxed at your ordinary income tax rate, not at capital gains rates.
