    Financial Aid

    Washington University in St. Louis is need-blind when reviewing applications, which means a student’s financial need will not influence an admission decision. In fact, 54% of undergraduates use financial aid to help cover the tuition and other costs. This may be scholarships, grants, student loans, or a combination of these.

    Generally, financial aid is monetary assistance awarded to students based on personal need or merit. Students who qualify for financial aid can use it to pay for college costs like tuition, books, and living expenses.

    The federal government is the largest provider of student financial aid. However, aid can also be given by state governments, colleges and universities, private companies, and nonprofits. The different types include:

    •  Scholarships: These can be awarded by schools and other organizations based on students’ academic excellence, athletic achievement, community involvement, job experience, field of study, or financial need.

    •  Grants: Generally based on financial need, these can come from federal, state, private, or nonprofit organizations.

    •  Work-study: This federal program provides qualifying students with part-time employment to earn money for expenses while in school.

    •  Federal student loans: This is money borrowed directly from the U.S. Department of Education. It comes with fixed interest rates that are typically lower than private loans.

    Colleges, universities, and state agencies use the Free Application for Federal Student Aid (FAFSA) to determine financial aid eligibility. The FAFSA can be completed online, but note that state, federal, and school deadlines may differ.

    You can find other financial aid opportunities on databases such as:

    •  US Department of Education – Search for grants from colleges and universities by state

    •  College Scholarship Service Profile (CSS) – A global college scholarship application used by select institutions to award financial aid

    •  SoFi Scholarship Finder – Use our handy tool to streamline your search by award type, location, level of study and more.

    Private Student Loans

    Some students take out student loans to help cover WashU tuition and other costs: 16% take out federal loans; 2% get private student loans (with an average amount of $27,740).

    Private loans are funded by private organizations such as banks, online lenders, credit unions, some schools, and state-based or -affiliated organizations. While Federal student loans have interest rates that are regulated by Congress, private lenders follow a different set of regulations so their qualifications and interest rates can vary widely.

    What’s more, private loans have variable or fixed interest rates that may be higher than federal loan interest rates, which are always fixed. Private lenders may (but don’t always) require you to make payments on your loans while you are still in school, compared to federal student loans, which you don’t have to start paying back until after you graduate, leave school, or change your enrollment status to less than half-time.

    Private loans don’t have a specific application window and can be applied for on an as-needed basis. However, if you think you may need to take out a private loan, it’s a good idea to submit your FAFSA first to see what federal aid you may qualify for, since it generally has better rates and terms.

    If you’ve missed the FAFSA deadline or you’re struggling to pay for school during the year, private loans can potentially help you make your tuition payments. Just keep in mind that you will need enough lead time for your loan to process and for your lender to send money to your school.
