In the 2017-18 school year, the average tuition for a student attending a four-year private university was $34,740. With tuition for some of the most expensive schools rising again, that average has surely gone up.

Student loan debt in America surpassed $1.5 trillion earlier in 2018, and it's a number that continues to grow as tuition rises. As a prospective college student, you need to be acutely aware of your finances, your family's financial situation and just how expensive your dream college is. The 13 schools on this list, for 2018-19, average out to a yearly tuition of $56,734. Now multiply that by four: $226,936.

For students and parents alike, knowing whether a prospective college is one of the most expensive ones in the country is necessary. It not only lets you know what it is costing your kids now, but paints a picture of how much future students will be paying when they start college.
