A money market account is a hybrid savings product that combines features of checking and savings accounts, usually offering higher interest rates in exchange for larger minimum balances and limits on withdrawals.
Most money market accounts are offered by banks and credit unions. They sit between a regular savings account and a money market fund (which is different—it's an investment product). The account lets you earn interest on your balance, write checks or use a debit card for withdrawals, and access your money without penalty, as long as you follow the account's rules about how often you can withdraw.
The trade-off is straightforward: you keep a larger amount of money in the account (often $2,500 to $25,000 minimum, though this varies by institution), and in return the bank pays you a higher interest rate than a standard savings account. The interest rate floats—it changes based on what the Federal Reserve does with its benchmark rate, so your earnings go up or down over time.
Key Takeaways
- Money market accounts require a higher minimum balance than regular savings accounts but pay interest rates that are typically higher than both savings and checking accounts.
- Federal rules limit you to six withdrawals per month (though this rule has been relaxed at some banks); exceeding the limit usually triggers a fee or account closure.
- Your deposits are insured by the FDIC (at banks) or NCUA (at credit unions) up to $250,000, so your principal is protected even if the institution fails.
- Interest rates on money market accounts change monthly or quarterly based on Federal Reserve policy, so your earnings are not locked in like they are with a certificate of deposit.
- You can write checks or use a debit card to access funds, making money market accounts more flexible than savings accounts but less flexible than checking accounts.
How the interest rate and minimum balance work
The interest rate on a money market account is variable, meaning it moves with market conditions. When the Federal Reserve raises its benchmark rate, banks typically raise the rates they offer on money market accounts within weeks or months. When rates fall, so do the rates on your account. You do not lock in a rate the way you do with a certificate of deposit (CD), so you cannot predict exactly what you will earn over a year.
The minimum balance requirement is real and matters. If your balance drops below the stated minimum—say, $2,500—the bank may charge a monthly fee (often $10 to $25) or convert your account to a regular savings account with a lower rate. Some banks waive the fee if you maintain the minimum; others charge it automatically if you fall short, even for one day. Read the account disclosure carefully to know which applies to you.
Different banks set different minimums. Online banks often have lower minimums ($500 to $1,000) and higher rates because they have fewer physical branches to maintain. Traditional brick-and-mortar banks may require $10,000 or more but offer in-person service. Credit unions typically fall somewhere in between.
Withdrawal limits and how they affect you
Federal Regulation D historically capped withdrawals at six per month for money market accounts. During the pandemic, the Federal Reserve suspended this rule, and many banks have not reinstated it. However, some banks still enforce it, and others have replaced it with their own limits. Before you open an account, ask the bank directly: "How many withdrawals can I make per month without a fee?"
If you exceed the limit, the bank typically charges a fee per excess withdrawal (often $10) or closes the account. Some banks will convert your account to a checking account instead, which usually pays no interest. This matters if you plan to use the account for frequent spending—money market accounts are better suited to money you want to earn interest on but do not need to touch often.
Transfers between your own accounts at the same bank usually do not count toward the limit. Withdrawals via ATM, debit card, check, or electronic transfer (ACH) typically do count. Ask your bank which transactions they count.
FDIC and NCUA insurance protection
Money market accounts at banks are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor, per bank. Money market accounts at credit unions are insured by the National Credit Union Administration (NCUA) up to $250,000 per depositor, per credit union. This means if the bank or credit union fails, you get your money back up to that limit.
The $250,000 limit applies to the total of all your deposits at that institution across all account types. If you have a $150,000 money market account and a $120,000 savings account at the same bank, only $250,000 is insured. The excess $20,000 is not protected. If you want to insure more than $250,000, you can open accounts at different banks or use different account ownership categories (joint accounts, retirement accounts, and trust accounts each have their own $250,000 limit).
Money market accounts versus savings accounts and CDs
A money market account pays more interest than a regular savings account because you commit to keeping a larger balance and accepting withdrawal limits. A regular savings account has no minimum balance requirement and no withdrawal limit, but the interest rate is lower—often 0.01% to 0.5% annually, compared to 4% to 5% for money market accounts (rates vary by bank and change frequently).
A certificate of deposit (CD) locks in a fixed interest rate for a set term—3 months, 1 year, 5 years—and pays more than a money market account because your money is truly locked away. If you withdraw early, you pay a penalty. A money market account gives you access to your money without penalty, so you sacrifice the higher CD rate in exchange for flexibility.
Choose a money market account if you have a lump sum you want to earn interest on but may need to access within a year or two. Choose a savings account if you need no minimum balance and frequent access. Choose a CD if you are certain you will not need the money for a specific period and want a may provide rate.
How to open a money market account
You can open a money market account online, by phone, or in person at a bank or credit union. You will need to provide your Social Security number, address, and proof of identity (a driver's license or passport). The bank will run a background check through ChexSystems, a banking history database, to verify you do not have a history of fraud or unpaid overdrafts at other banks.
You will also need to fund the account with at least the minimum balance. Most banks let you transfer money from another account, deposit a check, or wire funds. Some require you to mail a check or visit a branch in person. Ask the bank how long the deposit takes to clear—it is usually one to three business days for transfers and checks.
Before you open, compare rates across at least three banks or credit unions. Rates change frequently, and a difference of 0.5% to 1% on a $10,000 balance means $50 to $100 per year. Use a rate comparison site or call banks directly. Also confirm the minimum balance, withdrawal limits, and any monthly fees in writing.
When a money market account makes sense for you
A money market account works well if you have saved an emergency fund or a down payment and want it to earn interest while you decide what to do with it. It also works if you receive a bonus or inheritance and want a safe place to park the money for six months to a year while you plan.
A money market account does not make sense if you need to access your money frequently (more than six times a month), if you cannot meet the minimum balance, or if you need a may provide rate. It also does not make sense if you are saving for a goal more than five years away—a CD or a diversified investment account would serve you better.
Money market accounts are not investment accounts. They do not expose you to market risk, and they do not offer the growth potential of stocks or bonds. They are a safe, interest-bearing place to store cash you want to protect and grow modestly.
Frequently Asked Questions
Can I use a money market account like a checking account?
Partially. Most money market accounts come with a debit card and checkbook, so you can make purchases and pay bills. However, the withdrawal limit (usually six per month) means you will face fees if you use it like a primary checking account. Money market accounts are better for money you want to keep relatively untouched.
What happens if my balance drops below the minimum?
The bank will charge a monthly fee (typically $10 to $25) until your balance rises back above the minimum. Some banks convert the account to a regular savings account instead, which pays a lower rate. A few banks close the account. Check your account agreement to know which applies to you.
Is the interest rate may provide?
No. Money market account rates are variable and change based on Federal Reserve policy and bank decisions. Your rate may go up or down each month. If you want a may provide rate, open a CD instead.
How is a money market account different from a money market fund?
A money market account is a bank deposit product insured by the FDIC or NCUA. A money market fund is an investment product that buys short-term debt securities and is not insured. Money market funds can lose value; money market accounts cannot (as long as you stay within the insurance limit).
Can I have more than one money market account?
Yes, but the FDIC insurance limit applies to all your deposits at the same bank combined. If you open two money market accounts at the same bank with $150,000 in each, only $250,000 total is insured. To insure both fully, open them at different banks.
