A money market account combines features of savings and checking accounts

A money market account is a savings product that pays interest on your balance while giving you limited access to your money through checks or debit cards. Banks and credit unions offer them. The account sits between a regular savings account (which pays interest but limits withdrawals) and a checking account (which lets you withdraw freely but pays little or no interest).

The tradeoff is straightforward: you get a higher interest rate than a savings account, but the bank limits how many times per month you can withdraw money or write checks. Most accounts allow six withdrawals per statement cycle before fees kick in. In exchange for accepting this limit, you earn interest that compounds—meaning you earn interest on your interest—which grows your balance faster than a regular savings account.

Money market accounts are FDIC-insured at banks and NCUA-insured at credit unions, up to $250,000 per account owner per institution. That means if the bank fails, your money is protected up to that limit.

Key Takeaways

  • Money market accounts pay higher interest rates than savings accounts but limit you to about six withdrawals per month before charging fees.
  • Your balance must usually meet a minimum—often $2,500 to $25,000—to earn the advertised interest rate, and falling below it can trigger a monthly fee.
  • Interest rates on money market accounts change with the Federal Reserve's rate decisions, so your earnings go up or down over time.
  • You can access your money through checks, debit cards, or transfers, but exceeding the withdrawal limit costs you in fees that eat into your interest earnings.

How interest rates and minimums work on money market accounts

The interest rate a bank offers on a money market account depends on two things: the current Federal Reserve rate and how much competition exists in your area. When the Federal Reserve raises its benchmark rate, banks typically raise the rates they pay on savings products within weeks. When the Fed cuts rates, banks cut theirs. The rate you see advertised is the Annual Percentage Yield (APY), which includes the effect of compounding.

Most money market accounts require a minimum balance to earn the stated interest rate. This minimum varies widely—some accounts start at $2,500, others at $10,000 or $25,000. If your balance drops below the minimum, the bank usually pays you a lower interest rate on the full balance, or charges a monthly fee (often $10 to $25) that reduces your earnings. A few banks waive the minimum if you set up automatic monthly deposits or maintain a linked checking account with them.

Interest compounds daily or monthly, depending on the bank. Daily compounding means the bank calculates interest on your balance each day and adds it to your account, so the next day's interest is calculated on a slightly larger amount. This compounds faster than monthly compounding, but the difference is usually small unless your balance is very large.

Withdrawal limits and what happens when you exceed them

Federal rules once capped money market account withdrawals at six per month, but that rule was suspended in 2020 and has not been reinstated. However, individual banks still impose their own limits—typically six withdrawals per statement cycle—and charge fees when you exceed them. A fee is usually $10 to $25 per excess withdrawal.

The withdrawal limit applies to checks you write, transfers you initiate online or by phone, and debit card transactions. It does not apply to ATM withdrawals or in-person withdrawals at a branch. Some banks count all of these the same way; others count ATM and branch withdrawals separately. Read your account agreement or call the bank to understand exactly what counts toward your limit.

If you regularly need to withdraw money more than six times a month, a money market account is not the right choice. A regular checking account or high-yield savings account with no withdrawal limits would serve you better, even if the interest rate is lower.

How to access your money from a money market account

Money market accounts typically come with a debit card, checks, and online transfer options. You can write checks directly from the account, swipe the debit card at merchants or ATMs, or log into your bank's website and transfer money to another account. Some banks also offer mobile apps that let you transfer money or deposit checks by phone camera.

Transfers between your money market account and other accounts at the same bank are usually instant or complete within one business day. Transfers to accounts at other banks take one to three business days through the standard ACH system. If you need money faster, some banks offer same-day transfers for a fee, or you can withdraw cash at an ATM or branch.

The key difference from a checking account is that you should think of a money market account as a place to keep money you do not need to touch often. The withdrawal limit exists to encourage that behavior—the bank wants your money to stay in the account earning interest, not moving in and out constantly.

Money market accounts versus savings accounts and CDs

A high-yield savings account typically pays nearly as much interest as a money market account but has no withdrawal limits. The tradeoff is that savings accounts usually do not come with checks or a debit card, so accessing your money requires a transfer or a trip to the branch. If you think you might need to withdraw money more than six times a month, a savings account is simpler.

A Certificate of Deposit (CD) pays a higher interest rate than either a money market account or a savings account, but locks your money away for a set term—usually three months to five years. If you withdraw before the term ends, you pay a penalty that can wipe out several months of interest. A CD makes sense if you know you will not need the money for a specific period.

A regular checking account lets you withdraw as many times as you want with no fees, but pays little or no interest. Use it for everyday spending, and keep your emergency fund or savings goal in a money market account, savings account, or CD.

What to watch for when choosing a money market account

Compare the APY across banks, but do not choose based on rate alone. A bank offering 4.50% APY with a $25,000 minimum and a $15 monthly fee if you fall below it may actually pay you less than a bank offering 4.25% APY with a $2,500 minimum and no monthly fee. Calculate what you would actually earn in a year based on your balance and how often you plan to withdraw.

Check whether the bank is FDIC-insured (for banks) or NCUA-insured (for credit unions). Confirm the withdrawal limit and what counts toward it. Ask whether the bank will waive the minimum balance if you set up automatic deposits or link a checking account. Read the fee schedule—some banks charge fees for things like overdrafts, excess withdrawals, or falling below the minimum.

Online banks and credit unions often pay higher rates than brick-and-mortar banks because they have lower overhead costs. However, you lose the ability to walk into a branch and withdraw cash immediately. For most people, the higher rate is worth the trade-off, but if you value in-person service, a local bank or credit union may be worth a slightly lower rate.

How inflation affects your money market account earnings

The interest your money market account earns must outpace inflation, or your money loses purchasing power over time. If inflation is 3% per year and your account earns 2%, you are effectively losing 1% in real value each year. When the Federal Reserve raises rates to fight inflation, money market account rates usually rise too, which helps protect your savings.

During periods of low interest rates—such as 2020 and 2021—money market accounts paid very little, sometimes under 0.1% APY. Many people moved their savings to CDs or other products to earn more. When rates rose in 2022 and 2023, money market account rates climbed quickly, making them competitive again. This is why it pays to check your rate periodically and move your money if a better option appears.

Frequently Asked Questions

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

Technically yes, since most come with a debit card and checks. However, the six-withdrawal limit makes it inconvenient for everyday spending. Use a checking account for regular expenses and a money market account for money you want to save and earn interest on.

What happens if I exceed the withdrawal limit?

The bank charges a fee—usually $10 to $25 per excess withdrawal. If you exceed the limit regularly, those fees will eat into your interest earnings. Switch to a checking or savings account if you need more frequent access.

Do I pay taxes on money market account interest?

Yes. The interest you earn is taxable income. The bank will send you a 1099-INT form at the end of the year showing how much interest you earned, and you report that on your tax return. Interest earned in a money market account inside a retirement account (like an IRA) is not immediately taxable.

Can the bank change the interest rate on my money market account?

Yes. Banks can change rates at any time without notice, though they usually announce changes. Your rate will move up or down as the Federal Reserve adjusts its benchmark rate. This is different from a CD, where your rate is locked in for the full term.

Is my money safe in a money market account?

Yes, up to $250,000 per account owner per bank (FDIC insurance) or credit union (NCUA insurance). If the institution fails, the government guarantees your balance up to that limit. Keep balances under $250,000 at each bank to stay fully protected.
