Please contact your exchange coordinator to determine the costs for your exchange.  Tuition at Loyola is waived for all exchange students.  Loyola estimates that you will spend $500/ month on living expenses (food, entertainment and transportation).  You should plan for at least that, especially if you plan on taking trips outside of Baltimore.  Textbooks are also very expensive in the US.  You should expect to spend between $400 – 800 on textbooks depending upon what courses you are taking (business is more expensive) and whether you are taking four or five courses.
