Does Stanford meet 100% of demonstrated financial need for admitted students?

Yes. Stanford states that it meets 100% of demonstrated financial need for admitted undergraduates, including international students.

In practice, that means Stanford calculates what your family can reasonably contribute based on its own financial aid methodology, then covers the rest with a package that can include scholarship aid, student work, and a small student contribution. Stanford’s aid is need-based, not merit-based.

For most families, this is a very strong policy. Stanford also has especially generous benchmarks: families with typical assets and incomes below a certain level often pay no tuition, and families with lower incomes may have tuition, room, and board fully covered.

The important detail is that “full demonstrated need” does not always mean “free.” It means Stanford decides your demonstrated need using the financial information you submit, and then fills that gap according to its formula. So two colleges that both say they meet full need can still give different aid packages.
