A money market account is a special kind of savings account that you can use to store and grow your money. When you open a money market account, the bank will give you a bank card so you can access your money. Money market accounts usually pay higher interest rates than regular savings accounts, so your money will grow faster. Banks will usually put some limits on your account, like a minimum or maximum balance and some fees if you take out more than a certain amount of money. Ultimately, money market accounts are a great way to safely store and grow your savings with relatively low risk.
