A money market savings account is a hybrid between a regular savings account and a money market fund
A money market savings account (often called an MMA or money market deposit account) lets you earn a higher interest rate than a standard savings account, but it comes with restrictions on how often you can withdraw money. The bank pools your deposit with other customers' money and invests it in short-term, low-risk securities like Treasury bills and commercial paper. In exchange, you get a rate that typically beats regular savings—though the exact rate depends on how much you deposit, current market conditions, and the bank you choose.
The tradeoff is real: most money market accounts limit you to six withdrawals per month (federal rules used to enforce this strictly, though enforcement has loosened). Some banks charge a fee if you exceed that limit. You also usually need a higher minimum deposit to open one—often $2,500 to $25,000, depending on the institution. If you need to move money in and out frequently, a regular savings account is simpler. If you have a chunk of money sitting idle and can leave it mostly untouched, a money market account can earn you more.
Key Takeaways
- Money market accounts pay higher interest rates than regular savings accounts because banks invest your deposits in short-term securities, but you give up easy access to your money.
- Most money market accounts require a minimum deposit between $2,500 and $25,000, and some charge fees if you withdraw more than six times per month.
- Interest rates on money market accounts fluctuate with the market and vary widely by bank, so comparing rates across institutions matters before you open one.
- Your deposits are insured up to $250,000 per account holder per bank under FDIC protection, the same as regular savings accounts.
How interest rates and minimums differ between banks
Money market account rates change constantly because they track short-term interest rates in the broader economy. When the Federal Reserve raises its benchmark rate, banks typically raise money market rates within weeks. When rates fall, so do the rates banks offer you. This means the account that pays 4.5% today might pay 3.8% in six months if the Fed cuts rates.
Minimum deposits vary dramatically. Online banks often require $2,500 to $5,000 to open, while some regional banks ask for $10,000 or more. A few online banks have no minimum at all, though they may offer a lower rate to compensate. The rate you receive can also depend on your balance tier—some banks pay 4.2% on balances under $50,000 and 4.5% on balances above that. Before opening an account, check the bank's current rate sheet and minimum deposit requirement, because both affect whether the account makes sense for your situation.
Withdrawal limits and how they work in practice
Federal rules once capped money market withdrawals at six per month, but that rule was suspended in 2020 and has not been reinstated. However, individual banks still enforce their own limits—most allow six to ten withdrawals monthly before charging a fee, typically $25 to $35 per excess withdrawal. Some banks count only certain types of withdrawals (like transfers and checks) and not others (like ATM withdrawals), so read the fine print for your specific bank.
In practice, this means a money market account works best if you know you will not need the money for several months or longer. If you are saving for a down payment due in six months, or building an emergency fund you hope never to touch, a money market account makes sense. If you are managing monthly bills or know you will need to pull money out frequently, stick with a regular savings account where withdrawals are unlimited.
FDIC insurance and what happens if the bank fails
Money market savings accounts held at FDIC-insured banks are covered up to $250,000 per depositor per bank. This is the same protection that covers regular savings accounts, money market funds, and checking accounts. If you have $100,000 in a money market account at Bank A and $100,000 in a money market account at Bank B, both are fully protected. If you have $300,000 in a single money market account at one bank, only $250,000 is insured.
This protection does not cover money market mutual funds, which are different products sold by brokerages and investment firms. A money market mutual fund is not FDIC-insured and carries market risk. If you see "money market fund" in the product name, confirm whether it is a bank deposit account (FDIC-insured) or an investment fund (not insured) before depositing.
Comparing money market accounts to regular savings and CDs
A regular savings account offers unlimited withdrawals and no minimum deposit, but the interest rate is usually 0.01% to 0.5%—far below what a money market account pays. You trade convenience for a tiny return. A certificate of deposit (CD) locks your money away for a fixed term (three months to five years) and pays a may provide rate, usually higher than a money market account. But if you withdraw before the term ends, you pay a penalty. A money market account sits in the middle: better rates than savings, more flexibility than a CD, but withdrawal limits that fall between the two.
Choose a regular savings account if you need to access your money often or have less than the minimum deposit required. Choose a CD if you know you will not need the money for a specific period and want a may provide rate locked in. Choose a money market account if you have a lump sum you want to earn a competitive rate on, can leave it mostly untouched for months, and want the option to withdraw without a penalty if an emergency arises.
How to open a money market account and what documents you will need
Opening a money market account online takes 10 to 15 minutes. You will need your Social Security number, a government-issued ID, your current address, and a way to fund the account (a linked bank account or a check). Some banks also ask for your employment information and income, though this is less common for deposit accounts than for credit products.
After you submit your information, the bank verifies your identity and runs a check through ChexSystems, a banking history database. Most approvals happen instantly, and your account opens the same day. Funding the account can take one to three business days if you transfer from another bank, or you can mail a check. Once the money arrives, you can start earning interest immediately. The bank will send you a debit card and checks in the mail within one to two weeks.
What to watch for: fees, rate changes, and account closures
Money market accounts charge several types of fees. An excess withdrawal fee (usually $25 to $35) applies if you exceed the bank's monthly withdrawal limit. A monthly maintenance fee ($5 to $15) may apply if your balance falls below the minimum. Some banks charge an inactivity fee if you do not make a deposit or withdrawal for a set period, often 12 months. A few charge a fee to close the account early, though this is rare. Read the fee schedule before opening, because fees can erase the interest you earn.
Interest rates change without notice, and banks are not required to tell you in advance. You may see your rate drop 0.5% or more if the Fed cuts rates or if the bank decides to lower rates to reduce costs. If your rate drops significantly, you can close the account and move to a bank paying more—there is no penalty for closing a money market account. Some banks also close accounts if you do not maintain the minimum balance or if they suspect fraud, though this is uncommon.
Frequently Asked Questions
Can I use a debit card to withdraw from a money market account?
Yes, most banks issue a debit card with a money market account. However, some banks count debit card withdrawals toward your monthly limit, while others do not. Check your bank's rules before opening. ATM withdrawals are usually counted separately from the main withdrawal limit.
What happens if I exceed the withdrawal limit?
The bank charges a fee per excess withdrawal, typically $25 to $35. Some banks also close the account or convert it to a regular savings account if you repeatedly exceed the limit. Contact your bank to ask about their specific policy before you open.
Is a money market account the same as a money market fund?
No. A money market account is a bank deposit account insured by the FDIC. A money market fund is an investment product sold by brokerages and is not FDIC-insured. Money market funds can lose value if interest rates rise sharply. Always confirm which product you are opening.
Can I move money between my money market account and checking account without hitting the withdrawal limit?
It depends on the bank. Some banks count transfers between your own accounts as withdrawals; others do not. Ask your bank before opening whether internal transfers count toward the limit.
What interest rate should I expect right now?
Money market rates change constantly and vary by bank. As of early 2024, online banks typically offer 4% to 5.3%, while traditional banks often offer 0.5% to 2%. Check current rates on banking comparison sites or directly on bank websites, since rates posted here will be outdated within weeks.
