Cost of living

The cost of living varies drastically from city to city, state to state and type of accommodation. In general, although exceptions are frequent, living costs are lowest in the South and Southwest regions and highest in large cities and in New England.
Urban, rural and suburban campuses offer different advantages and pose separate problems. Be sure to weigh advantages and disadvantages, and choose an area where you will feel most comfortable.
A student usually has an opportunity of on-campus housing accommodation that is convenient due to its proximity to school, facilities offered and an opportunity to mingle with other students. Living alone off-campus has its advantages as well: i.e. your own freedom and proximity to city. This freedom however has a price. It will usually cost more to live off-campus. Many students spend their freshmen year on-campus and later when they are already familiar with the city and people, decide to share apartments in the city with friends.
Since the cost of living varies from location to location, it is only possible to give you a rough estimate of what your stay in the United states may cost.

Personal expenses: about $1,500-2,500 per academic year

Room and board rent per academic year (usually 9 months): $2,200-5,500; some of these might require extra furnishing like lamps, sheet, towels etc. which might cost up to $100-150.

Housing off-campus
Hotel accommodations: $ 25-100 per night
Single furnished room: $150-350 per month
Furnished one bedroom apartment: $200-600 (depending on the size and area of the city this is for basic apartments with basic furniture and draperies; larger or luxury apartments cost much more)
Unfurnished Apartments: $150-500 per month ( but the cost of buying the furniture might well exceed the cost of renting furnished apartments)
Meals: students living off campus often purchase meal tickets for dining halls; these range from $1000-1800. If you have your own kitchen, shopping for food is convenient and the food bill per month for one person runs from $150-250.
Bus/Metro Ticket: 80c to $1
Transportation cost varies; if you live on-campus, you may have fewer or no transportation costs. If you live off-campus you may budget for a bicycle or a car.
Price of gas: $1.45 per gallon, $15 to fill up the tank
Hamburger: $1-5 in fast food restaurant, $5-10 in a normal restaurant
