A money market account is a hybrid between a savings account and a checking account, with higher interest rates but limited withdrawal options

A money market account (MMA) holds your money at a bank or credit union and pays you interest on the balance. The interest rate is typically higher than a regular savings account because the bank can use your money for longer periods without you withdrawing it. In exchange, you get fewer withdrawals per month—usually between three and six—and you may need a larger opening deposit than a savings account requires.

The account sits somewhere between a savings account and a checking account. Like savings, it earns interest. Like checking, it usually comes with a debit card and check-writing ability, though the withdrawal limits make frequent use impractical. Most people use a money market account to hold money they want to earn interest on but might need within a few months, not money they spend from daily.

Key Takeaways

  • Money market accounts pay higher interest than savings accounts because you agree to limit your withdrawals to three to six per month.
  • The Federal Reserve's Regulation D caps certain types of withdrawals, though the exact rules depend on your bank and the withdrawal method.
  • Minimum opening deposits for money market accounts are typically $2,500 to $10,000, much higher than savings accounts.
  • Your money is insured up to $250,000 per account owner at FDIC-insured banks and NCUA-insured credit unions, the same as any other deposit account.

How the interest rate and withdrawal limits connect

Banks offer higher rates on money market accounts because they want your money to stay put. When you withdraw money frequently, the bank has less of your balance to lend out or invest. By limiting you to a set number of withdrawals per month, the bank can count on keeping most of your balance on hand and earning returns from it.

The withdrawal limit is usually stated as "six withdrawals per month" or "three withdrawals per month," depending on the bank. Some banks count all withdrawals the same way—whether you use the debit card, write a check, or transfer money online. Others count only certain types. For example, some banks limit transfers and checks but allow unlimited debit card withdrawals at ATMs. Read your account agreement to know which withdrawals count toward your limit.

If you exceed the limit, the bank may charge a fee per excess withdrawal, typically $10 to $25. Some banks will straightforward decline the transaction instead. A few will close the account if you repeatedly exceed the limit.

Minimum deposits and who should open one

Money market accounts require more money upfront than savings accounts. Most banks ask for $2,500 to $10,000 to open one, though some online banks have lowered this to $1,000 or eliminated it entirely. A few still require $25,000 or more. The higher the minimum, the higher the interest rate tends to be—the bank is betting you have more money to keep stable.

A money market account makes sense if you have money you want to earn interest on but expect to need within six months to a year. Examples: a down payment you are saving for, an emergency fund you want to earn more than a regular savings account pays, or money set aside for a specific purchase you know is coming. It does not make sense if you need to withdraw money frequently or if you have less than the minimum deposit available.

Interest rates and how they change

Money market account rates are variable, meaning they change when the Federal Reserve changes its benchmark interest rate. When the Fed raises rates, your bank usually raises the rate on your money market account within weeks. When the Fed cuts rates, your bank cuts yours too. You do not control the rate, and you cannot lock it in.

The rate your bank offers depends on the current Fed rate, how much competition exists in your area, and how much money the bank needs to attract. Online banks typically offer higher rates than brick-and-mortar banks because they have lower overhead costs. As of early 2024, money market account rates at online banks range from 4% to 5.35%, though this changes frequently. Rates at traditional banks are often 0.5% to 2% lower.

Interest is usually compounded daily and deposited monthly. That means the bank calculates interest on your balance every day, adds it to your account once a month, and you earn interest on that interest going forward.

FDIC and NCUA insurance on money market accounts

Money held in a money market account at an FDIC-insured bank is protected up to $250,000 per account owner. If the bank fails, the FDIC returns your money. At a credit union, the same protection applies through the NCUA (National Credit Union Administration) up to $250,000 per account owner.

The $250,000 limit applies per account owner, per bank, per account type. If you have a money market account and a savings account at the same bank, both are insured separately up to $250,000 each. If you have a joint money market account with your spouse, each of you is insured for $250,000, so the account itself is insured for $500,000 total.

Money market accounts versus money market funds

Do not confuse a money market account with a money market fund. They sound similar but work differently. A money market account is a bank deposit account insured by the FDIC or NCUA. A money market fund is an investment product sold by brokerages and mutual fund companies. It invests your money in short-term debt securities and is not insured by the FDIC.

Money market funds can offer higher returns but carry investment risk—the value can go down. Money market accounts are safer but earn less. If you see "money market fund" offered by an investment company, that is not the same product as a bank money market account.

How to open a money market account

Opening a money market account takes the same steps as opening any bank account. You choose a bank or credit union, provide your name, address, Social Security number, and initial deposit, and sign the account agreement. Most banks let you open online in 10 to 15 minutes. You will need a valid government ID and a way to fund the account—usually a transfer from another bank account or a check deposit.

Before you open, compare rates across several banks. The difference between a 4% rate and a 5% rate on $10,000 is $100 per year. Check the minimum deposit requirement, the withdrawal limit structure, and whether the bank charges monthly fees. Some banks charge $5 to $15 per month if your balance falls below the minimum, so factor that into your decision.

Frequently Asked Questions

Can I withdraw money from a money market account anytime?

You can withdraw money anytime, but your bank limits how many withdrawals you can make per month without penalty—usually three to six. Exceeding the limit typically costs $10 to $25 per excess withdrawal. The exact rules depend on your bank and which withdrawal methods count toward the limit.

What happens if I need to withdraw more than my limit allows?

You can still withdraw the money, but you will pay a fee for each withdrawal over the limit. Some banks charge per excess withdrawal; others may close the account if you repeatedly exceed the limit. Call your bank before you withdraw to understand the fee structure and whether there are exceptions for emergencies.

Is a money market account safe?

Yes, if it is at an FDIC-insured bank or NCUA-insured credit union. Your balance is protected up to $250,000. The money does not go into investments—it stays in the bank's vault or is lent out by the bank. Your only risk is that the bank fails, which is extremely rare because of federal regulation.

How often does the interest rate change?

The rate can change at any time, though most banks adjust it when the Federal Reserve changes its benchmark rate. You have no control over the rate and cannot lock it in. If rates fall, your earnings fall with them. If rates rise, your earnings rise.

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

Technically yes, but it is not practical. The withdrawal limit means you cannot make unlimited purchases or transfers. Most people use a money market account to hold money they do not spend from regularly, and a separate checking account for daily expenses.
