Students trying to decide between universities, have to consider the cost of  living at various universities when planning to Study in USA. Cost of living at universities vary a lot between each city and state.

Cost of living in Los Angeles is pretty high when compared to most of the other US cities.

Since, USC is located in downtown LA you need to make sure you live in a safe area. This should be the most concern and priority.

Usually a studio apartment in a safe neighborhood around USC will cost around $1,200 and a single bedroom will be around $1300-$1500.

I would say after sharing you need atleast $400 (max) for rent. Apart, for normal living another $200 can add-up. So approximately you will end-up spending $600 every month.

Students in studying in Texas spend around $250 to $400 per month.
