What a Money Market Account Is
A money market account is a savings account offered by banks and credit unions that combines features of a checking account and a traditional savings account. You earn interest on your balance, but you also get limited check-writing ability and a debit card — unlike a regular savings account, which typically offers neither. The trade-off is that money market accounts usually require a higher opening balance than savings accounts, often $2,500 to $10,000, though this varies by institution.
The interest rate you earn is typically higher than a standard savings account but lower than a certificate of deposit (CD). The rate is variable, meaning your bank can change it at any time. Most money market accounts are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per account holder per bank, so your principal is protected if the bank fails.
Key Takeaways
- Money market accounts require a higher minimum balance than regular savings accounts but pay more interest in return.
- You can write checks and use a debit card, but federal rules limit certain withdrawals to six per month.
- Interest rates are variable and set by your bank, so the rate you see today may change without notice.
- Your money is FDIC-insured up to $250,000, making it safer than keeping cash at home but less liquid than a checking account.
How Interest Rates and Minimums Work
Banks set their own interest rates and minimum balance requirements. A money market account at one bank might pay 4.5% annual interest with a $5,000 minimum, while another bank offers 3.8% with a $2,500 minimum. Rates change frequently — sometimes weekly — based on what the Federal Reserve does and what the bank decides. You will not automatically move to a higher rate if rates rise; you have to shop around and move your money if you want better terms.
The minimum balance requirement is real. If your balance drops below it, you typically pay a monthly fee of $10 to $25, or the bank may close your account. Some banks waive the minimum if you set up automatic deposits or link the account to direct deposit from your employer. Read the account agreement carefully, because the rules differ by bank.
Withdrawal Limits and How They Affect You
Federal rules allow you to make up to six withdrawals or transfers per month from a money market account before your bank can charge you a fee or close the account. This includes checks you write, debit card transactions, online transfers, and phone transfers. It does not include ATM withdrawals or in-person withdrawals at a branch.
In practice, most banks enforce this limit loosely during normal times but may tighten it if you exceed six withdrawals repeatedly. If you need to move money in and out frequently, a money market account is not the right tool — a checking account is. Money market accounts are designed for people who want to earn interest on savings they do not touch often but want the option to access the money without penalty.
Money Market Account vs. Other Account Types
| Account Type | Interest Rate | Minimum Balance | Check Writing | Withdrawal Limits |
|---|---|---|---|---|
| Checking Account | Usually 0% to 0.5% | $0 to $500 | Yes, unlimited | None |
| Savings Account | 0.5% to 2% | $0 to $500 | No | Six per month |
| Money Market Account | 2% to 5% | $2,500 to $10,000 | Yes, limited | Six per month |
| Certificate of Deposit (CD) | 3% to 6% | $500 to $2,500 | No | None until maturity |
A money market account sits in the middle. It pays more than a checking or regular savings account but less than a CD. It gives you more access than a CD but more restrictions than a checking account. Choose a money market account if you have a lump sum you want to earn interest on but might need to touch within a year or two.
How to Open a Money Market Account
Start by comparing rates and minimums at banks and credit unions in your area and online. Many online banks offer higher rates than brick-and-mortar banks because they have lower overhead. Visit the bank's website, call, or go to a branch and ask for the money market account disclosure document — this is a legal requirement and will spell out the rate, minimum, fees, and withdrawal rules.
To open an account, you will need a government-issued ID, your Social Security number, and proof of address (a utility bill or lease works). You will also need to fund the account with at least the minimum balance. Some banks let you transfer money from another account; others require you to deposit a check or wire money. Ask the bank how long it takes for the money to clear and when interest starts accruing — this varies.
Fees and Penalties to Watch For
The most common fees are a monthly maintenance fee (charged if your balance falls below the minimum), an excess withdrawal fee (charged if you exceed six withdrawals in a month), and an overdraft fee (charged if you write a check or use your debit card when the balance is too low). Some banks also charge a fee to close the account early or to transfer money out.
Read the fee schedule before you open the account. A bank advertising a high interest rate but charging $15 per month in maintenance fees may cost you more than a bank with a lower rate and no fees. Calculate the net return — the interest you earn minus the fees you pay — over a year to compare accounts honestly.
When a Money Market Account Makes Sense
A money market account works well if you have $5,000 or more sitting in a regular savings account earning almost nothing, and you do not plan to touch it for at least six months to a year. It also makes sense if you want a backup account for emergencies that pays better than a savings account but is safer and more liquid than a CD.
A money market account does not make sense if you need to move money in and out frequently, if you cannot maintain the minimum balance, or if you are saving for a specific goal with a known date (like a down payment in two years — a CD would lock in a higher rate). It also does not make sense if the only money market accounts available to you have high fees that eat up the interest you earn.
Frequently Asked Questions
Can I lose money in a money market account?
No. Your principal is protected by FDIC insurance up to $250,000. The interest rate can go down, so you earn less, but the money itself is safe. The only way to lose money is if you pay more in fees than you earn in interest.
What happens if I exceed six withdrawals in a month?
Your bank can charge you a fee per excess withdrawal, usually $10 to $25. If you repeatedly exceed the limit, the bank may convert your account to a checking account, close it, or restrict your access. Call your bank and ask what their specific policy is.
Is the interest rate may provide?
No. The rate is variable, meaning your bank can change it at any time without notice. Most banks lower rates when the Federal Reserve cuts rates, and raise them when the Fed raises rates. Check your account statements or log into your online banking to see if your rate has changed.
Can I have more than one money market account?
Yes, but FDIC insurance covers only $250,000 total across all money market accounts at the same bank. If you have $200,000 in one money market account and $100,000 in another at the same bank, only $250,000 is insured. Open accounts at different banks if you need to insure more than $250,000.
How do I move money out if I need it?
You can write a check, use your debit card, transfer money online to another account, or withdraw cash at a branch. The first six of these actions per month are free; additional ones may trigger a fee. Transfers to another bank typically take one to three business days.
