A money market account holds your cash and pays you interest, but limits how often you can withdraw
A money market account is a savings account that pays interest based on the current market rate for short-term loans. Banks use the money you deposit to make short-term loans to businesses and other banks, and they pay you a portion of what they earn. The interest rate changes with the market — it goes up when the Federal Reserve raises rates, and down when rates fall. You can withdraw your money, but federal rules limit you to six withdrawals per month (or statement cycle), and some banks charge a fee if you exceed that limit.
The account sits between a regular savings account and a money market fund. A savings account pays almost nothing. A money market fund invests in very short-term debt and can move faster, but it is not insured by the FDIC. A money market account at a bank is FDIC-insured up to $250,000 per depositor, per bank, so your principal is protected even if the bank fails.
Key Takeaways
- Money market accounts pay interest that changes with Federal Reserve rates, so your earnings rise and fall over time.
- You can make up to six withdrawals per month before most banks charge a fee or restrict further withdrawals.
- Your deposit is FDIC-insured up to $250,000, protecting your principal if the bank fails.
- The interest rate you receive depends on the bank and the current market, so rates vary widely between institutions.
- You can usually write checks or use a debit card, but some banks limit check-writing to a certain number per month.
How the interest rate is set and when it changes
Banks set their money market rates based on what the Federal Reserve does with its benchmark rate, called the federal funds rate. When the Fed raises rates, banks can charge more for loans, so they can afford to pay you more. When the Fed cuts rates, banks earn less, and they lower what they pay you. The lag between a Fed move and a rate change at your bank is usually one to two weeks, but it varies by bank.
Your rate is not locked in. It can change at any time, and banks are required to notify you before they lower your rate. Some banks lower rates quickly after a Fed cut; others wait longer. If you want to track whether your bank is keeping pace with the market, you can compare your current rate to the national average on sites like Bankrate or DepositAccounts, which update daily. If your bank falls far behind, moving your money to a higher-paying account at another bank is usually free and takes three to five business days.
The six-withdrawal limit and what happens if you exceed it
Federal Regulation D caps withdrawals from money market accounts at six per month (or per statement cycle, depending on your bank's billing). This rule exists because money market accounts are meant for savings, not frequent spending. Withdrawals include transfers to another account, checks you write, and debit card purchases. Deposits do not count toward the limit.
If you hit the limit, your bank can charge a fee — typically $25 to $35 per excess withdrawal — or freeze the account until the next statement cycle. Some banks close the account if you repeatedly exceed the limit. A few banks have removed the limit entirely, but most still enforce it. Before opening an account, ask the bank what happens if you go over six withdrawals, because the penalty varies.
How deposits and withdrawals actually move
When you deposit money by check or transfer, it takes one to two business days to clear and show up in your account. During that time, the bank holds the funds to verify the check or confirm the transfer came from a real account. Once cleared, the money earns interest immediately at the rate posted for that day.
When you withdraw by check or transfer, the money leaves your account the same day you request it, but it may take one to three business days to reach the other account. If you write a check, the recipient has to deposit it first, so the actual cash movement can take several days. During that time, the money is still in your account and still earning interest. Once the check clears or the transfer completes, interest stops accruing on that amount.
What you actually earn and how interest compounds
Interest on money market accounts is usually compounded daily and credited monthly. That means the bank calculates what you owe based on your balance every single day, adds all those daily amounts together, and deposits the total into your account once a month. If you have $10,000 in an account paying 4.5% annual interest, you earn roughly $37.50 per month (the exact amount depends on the number of days in the month and the bank's calculation method).
The interest you earn is taxable income. At the end of the year, your bank sends you a 1099-INT form showing how much interest you received. You report this on your tax return. If you earned more than $10 in interest across all accounts, the bank must send you the form; if you earned less, they may not, but you still owe tax on it.
Comparing money market accounts to other savings options
A high-yield savings account works similarly — it pays interest that changes with the Fed, and deposits are FDIC-insured — but it usually has no withdrawal limit. The trade-off is that money market accounts sometimes pay slightly more interest because the withdrawal restriction lets banks count on the money staying put longer. In practice, the difference is often less than 0.1%, so the withdrawal limit may not be worth it unless you truly will not need the money for months.
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 early, you pay a penalty. CDs often pay more than money market accounts because the bank knows exactly how long it has your money. A money market account gives you flexibility; a CD gives you a higher rate if you can commit.
A money market fund is similar in name but different in structure. It is a mutual fund that invests in short-term debt, not a bank account. It is not FDIC-insured, so if the fund's investments fail, you could lose money. It can move faster than a bank account and sometimes pays more, but the risk is higher.
Fees and conditions that reduce your earnings
Beyond the excess withdrawal fee, money market accounts can charge a monthly maintenance fee (usually $5 to $15), an inactivity fee if you do not deposit or withdraw for several months, or a fee to close the account early. Some banks waive the maintenance fee if you keep a minimum balance — often $2,500 to $10,000 — or set up direct deposit. Read the fee schedule before you open an account, because a high fee can wipe out months of interest earnings.
If your account falls below the minimum balance, some banks charge a fee or lower your interest rate. A few banks charge a fee just to have the account open, regardless of balance. Online banks typically charge fewer fees than brick-and-mortar banks because their overhead is lower, so if fees matter to you, online accounts are usually the better deal.
How to move money in and out without hitting the withdrawal limit
If you need to access your money frequently, you can use a strategy called "laddering." Open a regular savings account or checking account at the same bank for everyday spending, and keep your money market account as a reserve. Transfer money from the money market account to your checking account once a month (that counts as one withdrawal), and then spend from checking as needed. This way, you stay within the six-withdrawal limit while still having access to your cash.
Another option is to use the money market account only for money you will not touch for at least a few months. If you have an emergency fund or a down payment fund that you are building slowly, a money market account is a good fit. If you need to dip in and out frequently, a high-yield savings account with no withdrawal limit is better, even if the rate is slightly lower.
Frequently Asked Questions
Can I lose money in a money market account?
No, as long as the bank is FDIC-insured and you stay within the $250,000 insurance limit. Your principal is protected. You can only lose money if you withdraw when interest rates have fallen and you move to a lower-paying account, but that is a choice you make, not a loss of the account itself.
What happens if I exceed six withdrawals in a month?
Your bank can charge a fee per excess withdrawal (typically $25 to $35) or freeze the account until the next statement cycle. Some banks close the account if you repeatedly go over the limit. Check your bank's policy before opening the account.
Do I pay taxes on money market interest?
Yes. Interest is taxable income. Your bank sends you a 1099-INT form at the end of the year if you earned $10 or more, and you report it on your tax return. You owe tax even if the bank does not send the form.
Is a money market account better than a savings account?
A money market account usually pays more interest because of the withdrawal limit, but the difference is often small — less than 0.1%. If you need frequent access to your money, a high-yield savings account with no limit is usually better. If you can leave the money alone for months, a money market account may earn you slightly more.
Can I write checks from a money market account?
Many banks let you write checks, but some limit you to a certain number per month (often three to six). Checks count toward your six-withdrawal limit. Ask your bank before opening the account if check-writing matters to you.
