The
average cost for a year of college is $15,100 at a public university and $32,900 at a private university. Over the last 10 years, the cost of a year of education at a public university has increased 6.5 percent per year. As a result of the (unfortunate in this case) exponential effect of compounding, this means that in 2030 the average cost per year of a public college will be $44,047.
