We believe everyone should be able to make financial decisions with
confidence. While we don't cover every company or financial product on
the market, we work hard to share a wide range of offers and objective
editorial perspectives.
So how do we make money? Our partners compensate us for advertisements that
appear on our site. This compensation helps us provide tools and services -
like free credit score access and monitoring. With the exception of
mortgage, home equity and other home-lending products or services, partner
compensation is one of several factors that may affect which products we
highlight and where they appear on our site. Other factors include your
credit profile, product availability and proprietary website methodologies.
However, these factors do not influence our editors' opinions or ratings, which are based on independent research and analysis. Our partners cannot
pay us to guarantee favorable reviews. Here is a list of our partners.

What is a cash sweep account or sweep account?
A cash sweep account automatically transfers uninvested cash — typically from a bank or brokerage account — to higher-yielding accounts or investments, such as banks, money market funds or short-term Treasury securities. These options are generally low risk and keep cash easily accessible.
Uninvested cash might include account deposits, dividends or interest from investments, or proceeds from an investment sale.
The main purpose of a cash sweep account, also called a sweep account, is to earn interest on money that would otherwise sit idle.
Many sweep accounts also offer banking features such as electronic payments and check-writing services. The interests rates on sweep accounts can vary.
You may be asked to choose a cash sweep program when opening an investment account, or you may be automatically enrolled in one.
Some programs are free, while others may charge fees such as account management or maintenance fees. Some cash sweep accounts also have minimum account balance requirements.
