Attending Duke University as an undergraduate student involves a substantial financial commitment, with the total estimated annual cost of attendance—encompassing steep private tuition, mandatory institutional fees, housing, dining plans, textbooks, and personal expenses—surpassing ninety thousand dollars per year. Over a standard four-year undergraduate degree program, total cumulative expenses frequently exceed three hundred and sixty thousand dollars, though the university's robust need-based financial aid policies ensure that many qualifying students receive substantial tuition assistance.
