What is a money market account?
A money market account, or MMA, is a type of savings account that can come with perks such as check writing or a debit card. Though MMA interest rates have historically been higher than those of regular savings accounts, many currently are roughly the same. MMAs usually require a higher minimum balance.
Money market accounts are insured by the Federal Deposit Insurance Corp. (at banks) and the National Credit Union Administration (at credit unions).

Should I open a money market account?
A money market account is worth considering if you’re looking for a safe place to deposit a large chunk of money and earn some interest. Here are good reasons to open an MMA:
- Your bank’s money market account has a high interest rate
- You want access to funds in a pinch
- You need the ability to write up to six checks per month
- You want a debit card on your account that you can use up to six times per month
- You plan to deposit several thousand dollars and want the safety of an insured account at a bank or credit union account
Be sure to shop around, though, to make sure an MMA is the best option. Keep in mind that high yield savings accounts often have better interest rates and lower minimum deposits.

A money market or high yield savings account also could be a good place to store your emergency fund. It’s smart to keep this money separate from your daily-use checking account, and a higher yield might help your funds grow a bit faster. With an MMA, you could also write a check to cover any surprise expenses — if your bank offers that feature.
How to choose a money market account
If you decide a money market account is your best option, look for one with the best rates and no monthly fees. It also should have a reasonable minimum balance. Some institutions require as much as $10,000 to open an account.

Money market accounts vs. other accounts
MMAs have features that overlap those of other bank accounts, but there are important differences.
|Type of account||How is the interest rate?||Why open this account?|
|Money market account||Competitive with savings account rates||
|Savings account||Competitive with money market account rates||
|Certificates of deposit (CDs)||Generally highest of all bank accounts|

Take note of some crucial differences, though:
- A money market account is not a money market fund, an investment that could lose value if the market falls. Money market accounts are backed by the FDIC or NCUA, up to $250,000 per depositor.
- An MMA is not a checking account. Some money market accounts have check-writing and debit card features. But, as with regular savings accounts, they are limited by the Federal Reserve to six “convenient” transfers or withdrawals a month — including by check, debit card swipe or online transfer. If you want the ability to write checks and make frequent withdrawals, you may be better off opening an interest-bearing checking account. (You can look for high-interest accounts by entering your ZIP code and minimum deposit in our interest checking tool.)
- An MMA is a type of savings account, but one that may have a check-writing ability. If you want a basic account and aren’t interested in checks, you can find comparable or better rates with some high-yield online savings accounts. Check this list of savings accounts with top yields.
- Another type of savings account is a certificate of deposit. It requires you to set aside money for months or years, while an MMA allows easier withdrawals. But a CD could fill the bill if you want to earn better rates and can afford to stash your cash for a while. NerdWallet does a roundup of the best CD rates by month.
