A "money market account" is a type of savings account that typically pays higher interest rates than traditional savings accounts. It is often used by individuals who want to earn more interest while retaining quick access to their funds. However, there are several synonyms for this type of account, including cash management account, high-yield savings account, money market deposit account, and sweep account. These accounts offer similar features and benefits, so it is important to compare the interest rates and fees associated with each before choosing the best option for your financial needs and goals.
