A money market account is a hybrid between a savings account and a checking account, offered by banks and credit unions

A money market account (MMA) combines features of both savings and checking accounts. You get a debit card or checkbook to withdraw money, like a checking account, but the account earns interest on your balance, like a savings account. The tradeoff is that federal rules limit how many withdrawals you can make each month—typically six total, though some institutions set lower limits.

Money market accounts are FDIC-insured at banks and NCUA-insured at credit unions, meaning your deposits up to $250,000 are protected if the institution fails. The interest rate you earn varies by institution and changes based on what the Federal Reserve does with its benchmark rate. Rates are higher than traditional savings accounts but usually lower than certificates of deposit (CDs) for the same time commitment.

You need to meet a minimum deposit to open one—this ranges from $500 to $25,000 depending on the bank. Some institutions waive the minimum if you set up automatic transfers or maintain a certain monthly balance. Monthly maintenance fees are common but often waived if you keep your balance above a stated threshold.

Key Takeaways

  • Money market accounts let you earn interest while keeping access to your money through a debit card or checks, unlike savings accounts that typically offer no withdrawal method.
  • Federal rules cap withdrawals at six per month, and exceeding this limit can result in fees or account closure, so these accounts work best for money you do not need to touch frequently.
  • Interest rates on money market accounts change with Federal Reserve decisions and vary widely between institutions, so comparing rates across banks and credit unions is worth doing before opening one.
  • Minimum deposits and monthly fees differ by institution; some banks waive both if you maintain a high balance or set up automatic deposits.

How the withdrawal limit works in practice

Federal Regulation D limits you to six withdrawals or transfers per month from a money market account. This includes debit card purchases, checks written, electronic transfers, and ATM withdrawals. Deposits do not count toward this limit—you can deposit as much as you want.

What happens when you exceed six withdrawals varies by bank. Some charge a fee per excess withdrawal (typically $10 to $25). Others convert your account to a checking account, which removes the interest-earning feature. A few institutions close the account entirely. Check your bank's specific policy before opening, because the consequence matters if you think you might need frequent access.

The six-withdrawal rule exists because money market accounts are technically classified as savings accounts under federal law, even though they function like checking accounts. This classification is why they earn interest—the bank can lend out your balance—but also why the withdrawal cap applies.

Interest rates and how they change

Money market account rates move in the same direction as the Federal Reserve's benchmark rate. When the Fed raises rates, banks typically raise the rates they offer on money market accounts within weeks. When the Fed cuts rates, banks lower their rates as well. This means your earnings can shift significantly over a year if the Fed makes multiple moves.

The actual rate you receive depends on the bank or credit union and your account balance. Some institutions offer tiered rates—a higher percentage if you maintain $50,000 or more, a lower percentage for smaller balances. Online banks typically offer higher rates than brick-and-mortar banks because they have lower overhead costs. Credit unions sometimes offer competitive rates to members, though you must be a member to open an account.

You can compare current rates across institutions using rate-tracking websites, but these sites do not may provide the rates will still be available when you explore. Call or visit the bank's website directly to confirm the rate before you deposit money.

Minimum deposits and monthly fees

Opening a money market account requires an initial deposit that ranges from $500 at some online banks to $25,000 at certain large institutions. The minimum does not have to stay in the account—once it is open, you can withdraw it and drop below the minimum. However, doing so often triggers a monthly maintenance fee.

Monthly fees typically range from $5 to $15 and are charged if your balance falls below the stated minimum. Many banks waive the fee if you maintain a certain balance (often $1,000 to $10,000), set up automatic monthly deposits, or keep a linked checking account open at the same institution. Read the fee schedule carefully, because a $10 monthly fee erodes the interest you earn on a small balance.

Some banks offer no-fee money market accounts with no minimum deposit, though these tend to have lower interest rates. The trade-off is worth calculating: a $0 fee account at 4.00% interest might earn you more than a $10-fee account at 4.75% interest if your balance is under $2,000.

Money market accounts versus savings accounts and CDs

The main difference between a money market account and a regular savings account is access. A savings account typically offers no debit card or checkbook—you withdraw money through an ATM, online transfer, or by visiting a branch. A money market account gives you a debit card and checks, so you can spend directly from the account. Both earn interest, and both are capped at six withdrawals per month under federal rules.

Money market accounts usually pay more interest than savings accounts at the same bank, but the difference is often small—sometimes less than 0.25%. The higher rate reflects the higher minimum deposit required. If you do not need check-writing access and want to keep your balance low, a savings account may be simpler.

Certificates of deposit (CDs) typically pay more interest than money market accounts because you agree to lock your money away for a set term—three months, one year, five years. If you withdraw before the term ends, you pay a penalty that can erase months of interest. Money market accounts have no lock-in period, so you keep your flexibility. Choose a CD if you know you will not need the money for a specific period and want the highest may provide rate.

Who should consider a money market account

Money market accounts work best for people who have a chunk of money they want to earn interest on but might need to access within a few months. Examples include an emergency fund you are building, money set aside for a down payment, or a bonus you received that you have not yet decided how to use.

They are less suitable if you make frequent purchases from savings or if you need to move money in and out more than six times a month. In that case, a regular checking account (which has no withdrawal limits) paired with a high-yield savings account (which earns more interest) is a better structure.

Money market accounts also make sense if you want a single account that does both—earns interest and lets you write checks or use a debit card—without managing two separate accounts. The convenience of one account with one login may outweigh the slightly lower rate compared to splitting your money between a checking and savings account elsewhere.

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. Online applications typically take 10 to 15 minutes and require your Social Security number, address, and employment information. The bank will check your banking history through ChexSystems, a database that tracks account closures and overdrafts. A negative history may result in denial, though some banks specialize in second-chance accounts.

After you submit your process, the bank verifies your information and either approves or denies you within one to three business days. If approved, you fund the account by transferring money from another bank account or depositing a check. The funds typically appear within one to three business days, depending on how you transfer them.

Before opening, confirm the current interest rate, minimum deposit, monthly fee, withdrawal limit, and what happens if you exceed it. These details vary significantly between institutions and directly affect how much money you will earn and how much it will cost you to maintain the account.

Frequently Asked Questions

Can I use a money market account as my main checking account?

Technically yes, because you get a debit card and checks. However, the six-withdrawal limit makes it impractical if you spend from the account multiple times per week. Most people use money market accounts for savings goals and keep a separate checking account for daily spending.

What happens if I go over six withdrawals in a month?

The consequence depends on your bank's policy. Some charge a fee per excess withdrawal ($10 to $25). Others convert your account to a checking account, which removes the interest. A few close the account. Check your bank's fee schedule before opening to know what to expect.

Is my money safe in a money market account?

Yes, up to $250,000 per account owner at FDIC-insured banks and NCUA-insured credit unions. If the institution fails, the government backs your deposit. This protection applies regardless of the interest rate or account type.

Do money market account rates ever go down?

Yes. Rates move with Federal Reserve decisions. When the Fed cuts its benchmark rate, banks lower the rates they offer on money market accounts within weeks. Your earnings can decrease significantly if the Fed makes multiple rate cuts.

Can I withdraw all my money at once from a money market account?

Yes, but it counts as one withdrawal against your six-per-month limit. You can withdraw your entire balance whenever you want without penalty. The withdrawal limit is about frequency, not amount.
