ALMOST? 15 colleges now cost $100K+ per year — and almost none of them are worth it.

Fifteen higher ed institutions cracked the six-figure pricetag this year, up from a just two the previous year, according to an analysis from the the Washington Post.

The most expensive schools in the US are:

Harvey Mudd College, Calif. — $104,512
Duke University, NC — $103,975
University of Chicago, Ill. — $103,821
University of Southern California, Calif. — $103,162
Barnard College, NY — $103,000
Washington University, Mo. — $102,260
Smith College, Mass. — $102,226
Fordham University, NY — $102,188
Claremont McKenna College, Calif. — $101,990
Vassar College, NY — $101,051
Wesleyan University, Conn. — $101,030
New York University, NY — $100,998
Georgetown University, DC — $100,864
Colgate University, NY — $100,224
Haverford College, Penn. — $100,026

Ivy League schools Brown, Columbia and Cornell were close behind, each charging just under $100,000 per year.

Despite those huge prices, separate statistics raised questions about what the money is buying — none of the 15 most expensive schools appeared equally high in college rankings of the best returns on investment.

Insane.
