Money market accounts blend checking and savings features, but they are legally savings accounts

A money market account is a savings account under federal banking law, even though it acts like a hybrid. It has a savings account's restrictions — you can make only six transfers or withdrawals per month before the bank charges you a fee or closes the account — but it also has a debit card and check-writing privileges that look like checking. The key difference: a money market account earns interest on your balance, while a standard checking account typically does not.

Banks classify money market accounts as savings because they are designed to hold money you are not spending every day. The interest rate is higher than a regular savings account but usually lower than a certificate of deposit (CD). The tradeoff is access: you can reach your money faster than with a CD, but you cannot treat it like a checking account without hitting withdrawal limits and fees.

The hybrid nature is what confuses people. You get check-writing and a debit card, which feel like checking. But the six-transaction limit per month is a savings account rule, set by the Federal Reserve. If you exceed it, you pay a fee — usually $10 to $25 per excess transaction — or the bank may convert your account or close it.

Key Takeaways

  • Money market accounts are savings accounts under federal law, which means they have a six-transaction limit per month and earn interest on your balance.
  • The debit card and check-writing privileges make them feel like checking accounts, but using them beyond the monthly limit triggers fees or account closure.
  • Interest rates on money market accounts are higher than regular savings accounts but lower than CDs, and rates vary by bank and balance tier.
  • If you need unlimited transactions and no interest, a checking account is the right tool; if you want to earn interest and rarely move money, a money market account works better.

Why the six-transaction limit exists

The Federal Reserve set the six-transaction rule for savings accounts to encourage people to keep money in savings rather than treat it as a spending account. The rule applies to money market accounts because they are classified as savings products. Banks enforce this limit by charging a fee for each transaction over six per month, or by downgrading your account to a non-interest-bearing checking account.

In practice, most people do not hit this limit. If you use your money market account as a true savings vehicle — moving money in once a month and leaving it alone — you will never pay a fee. The limit only matters if you are writing checks or using the debit card multiple times per week.

Some banks have relaxed enforcement of this rule since the pandemic, but it remains on the books. Always check your account agreement to see whether your bank charges fees for excess transactions or simply converts your account type.

When to use a money market account instead of checking

Use a money market account if you have money you want to keep separate from your daily spending and you want it to earn interest. Common scenarios include an emergency fund, a down payment fund, or money set aside for a specific goal six months to two years away. The interest rate — which varies by bank but typically ranges from 0.01% to 5% depending on the current rate environment — means your balance grows without you doing anything.

A checking account is the right choice if you need unlimited transactions, write checks frequently, or use a debit card multiple times per week. Checking accounts do not earn interest, but they do not penalize you for moving money in and out. If your primary need is a place to park your paycheck and pay bills, checking is simpler and cheaper.

Some people maintain both: a checking account for bills and daily spending, and a money market account for savings. This setup lets you earn interest on money you are not touching while keeping your spending money in a no-limit account.

How interest rates and minimum balances work

Money market account interest rates are set by each bank and change based on the Federal Reserve's interest rate decisions. When the Fed raises rates, banks typically raise money market rates within weeks. When the Fed cuts rates, money market rates fall. The rate you receive depends on your bank and, at many banks, your account balance.

Many banks use tiered rates: a lower rate on balances under $10,000, a higher rate on balances from $10,000 to $100,000, and an even higher rate on balances above $100,000. Some banks have no minimum balance requirement; others require $1,000 to $25,000 to open the account or to earn the advertised rate. Read the account terms before opening to understand what rate you will actually receive.

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 the following month. Over time, this compounds and grows your balance faster than a simple savings account.

Fees and penalties to watch for

The most common fee is the excess-transaction fee, charged when you exceed six transfers or withdrawals per month. This fee is typically $10 to $25 per transaction over the limit. Some banks charge a monthly fee if you fall below the minimum balance, ranging from $5 to $15. A few banks charge an inactivity fee if you do not make a deposit or withdrawal for a set period — usually 12 months — though this is less common.

Overdraft fees apply if you write a check or use the debit card and your balance goes negative. These fees range from $25 to $35 per overdraft and can stack if multiple transactions post on the same day. Some banks offer overdraft protection, which links your money market account to a checking account or line of credit and transfers money automatically if you overdraft.

Always review the fee schedule before opening a money market account. Some banks advertise high interest rates but charge fees that eat into your earnings. A bank with a slightly lower rate and no fees may leave you with more money in the end.

Money market accounts versus money market funds

Do not confuse a money market account with a money market fund. A money market account is a bank product insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor per bank. A money market fund is an investment product sold by brokerages and mutual fund companies, not insured by the FDIC, and its value can fluctuate based on the securities it holds.

Money market accounts are safer because your balance is may provide by the FDIC. Money market funds offer potentially higher returns but carry investment risk. If you want may provide safety and interest, choose a money market account at a bank. If you are comfortable with risk and want higher potential returns, a money market fund through a brokerage may be worth exploring — but that is a different product entirely.

How to move money in and out without hitting the limit

The six-transaction limit counts transfers and withdrawals, but not deposits. You can deposit money into a money market account as many times as you want without penalty. The limit applies only to money leaving the account: checks you write, debit card purchases, transfers to other accounts, and ATM withdrawals.

To stay under the limit, batch your transactions. Instead of writing one check per week, write all your checks at once. Instead of transferring money to your checking account multiple times per month, do it once. If you need to access money frequently, keep a separate checking account and transfer a lump sum once per month.

Some banks offer a workaround: a linked checking account with no transaction limit. You keep most of your money in the money market account earning interest, and transfer to checking only when you need to spend. This setup gives you the best of both worlds — interest on savings and unlimited spending flexibility.

Frequently Asked Questions

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

Technically yes, but it is not practical if you spend money frequently. The six-transaction limit means you will hit fees quickly if you write checks or use the debit card more than once or twice per week. A checking account is designed for frequent transactions and costs less in the long run.

Do I lose interest if I withdraw money before a certain date?

No. Money market accounts are not like CDs, which charge a penalty for early withdrawal. You can withdraw money anytime without losing interest. The only cost is the excess-transaction fee if you exceed six withdrawals per month.

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

Your bank will charge a fee — usually $10 to $25 — for each transaction over six. If you repeatedly exceed the limit, the bank may convert your account to a non-interest-bearing checking account or close it entirely. Check your account agreement to see your bank's specific policy.

Is my money safe in a money market account?

Yes, as long as your bank is FDIC-insured. The FDIC guarantees up to $250,000 per depositor per bank, so your money is protected even if the bank fails. Check your bank's FDIC status on the FDIC website if you are unsure.

Can I get a higher interest rate by moving to a different bank?

Yes. Money market rates vary significantly by bank. Shopping around every few months — especially when the Fed changes rates — can help you find a bank offering a higher rate on your balance. Some online banks offer higher rates than traditional brick-and-mortar banks because they have lower overhead costs.
