Hi there, it really depends a lot on which city you are going to and what your program already includes. Do you have to pay extra for field trips, text books, readers, housing? How many trips do you intend to do?
Let me give you two website
- Compare cost of living in different cities
Cost of Living
- Read the budgeting session on this study abroad program in Perugia, to see what you should consider in your budget. Of course some of those info refers to this program in particular.

Hope this helps a little.
