One of the best things about opening a money market account through Discover is that there are no account fees. If you have more than $100,000 to save, then you can earn a 1.50% APY. For balances that are under $100,000, you can still receive a 1.45% APY. A money market rate, also called the APY (annual percentage yield) rate, is the rate at which your account will earn interest over the course of a year. For example, if you store $1,000 in a money market account with a 1.00% APY rate, you’ll have $1,010 in your account after one year. UFB Direct's Premium Money Market Account has a very high rate, but only on accounts with $25,000 or more. And you need to maintain a $5,000 average daily balance in order to avoid monthly fees. 1.80% APY for balances of $25,000 and above.
