The answer varies depending upon which university you attend and the state it is located in. I live on campus with the school provided housing and eat meals in the school dining hall. My living cost is slightly more than $15000 each year here in New Haven, CT.
If you live in an apartment with friends and cook your own meal, you can bring down the cost to less than $10,000. Again, living costs in cities like New York, Washington, Boston or any other major cities is expensive. The cost greatly varies depending upon which university you attend.
