NEW YORK (TheStreet) -- Over the past few decades, the average cost of attending college in the United States has increased faster than the rate of inflation.

Family income, unfortunately, hasn't been growing enough to offset these increases, making it even more difficult for many people to afford higher education.

Although many students apply for scholarships and financial aid, there is still a substantial amount of student debt taken out each year to cover all the costs.

So, how much does a single year of college cost? For a four-year college, tuition alone can range from less than $1,500 to more than $50,000.

Using data from The College Board, we have compiled a list of 25 colleges in the United States with the highest tuition fees. Although only private four-year colleges make the list, public, private, and for-profit two- and four-year colleges were all considered.

These prices don't include room and board, books, health care, or any other fees that students may need to pay.
