Money market account
A bank deposit account that pays interest like a savings account and may include checks or a debit card. It is FDIC insured.
A money market account is a savings account with a few checking features. Some require a higher minimum balance to earn the best rate, and some limit how many withdrawals you can make each month.
Do not confuse it with a money market fund. A money market fund is an investment sold by brokerages. It aims to be very stable, but it is not FDIC insured.
