What can change this

  • Savings and investments above a typical amount raise the price. The curve assumes typical assets.
  • Home equity: some colleges that use the CSS Profile count it. Check this college's own aid page or calculator.
  • Divorced or separated parents: colleges with their own formula usually ask for both parents' finances.

In the college's words:

“Financial assistance for undergraduate students is a top priority for Washington University, and our commitment in this area continues to expand greatly with increased need-based scholarship funds. We meet 100% of need for our admitted students. In addition to this commitment, Washington University also offers the following programs: 1) No Loan: Washington University eliminates loans as part of its undergraduate financial aid offer to all students. 2) WashU Pledge: Incoming first-year, full-time Missouri and southern Illinois students who are from families with annual incomes of $75,000 or less will be provided a free undergraduate education. The WashU Pledge covers the full cost of a Washington University education which includes tuition, housing, food and fees, and is guaranteed for four years. 3) First-Year Grants: First-year students who are from families with incomes of $75,000 or less will receive $1,500 toward the cost of start-up supplies and a $1,550 grant to replace the expectation that students work the summer before starting at Washington University. 4) Technology Grant: Incoming students who have any need-based scholarship or grant aid will receive a bookstore credit of $1,293 to cover the cost of the university standard minimum-requirement-meeting computer. Washington University no longer considers home equity as part of its need-based financial aid offers.”
