The cost of university dormitories in the United States varies depending on factors such as the school, region, and dormitory type. Generally speaking, the cost of on-campus housing at a US university for a year (9 months) is approximately US$3,000-7,500. Below are some dormitory costs for different school types and regions:

Public Universities:
For example, at the University of Washington-Seattle, Residence Halls cost US$7,059-9,084 per year, Apartments cost US$8,040-18,009 per year, and Family Housing costs US$9,210-11,610 per year.
Private universities:
For the 2024-2025 academic year, traditional-style dormitories at American universities cost between $4,240 and $5,760 per semester for double rooms and between $7,250 and $8,640 per semester for single rooms; for suite-style dormitories, double rooms cost between $6,600 and $6,940 per semester and single rooms cost between $8,270 and $10,410 per semester; for apartment-style dormitories, double rooms cost between $7,050 and $7,120 per semester and single rooms cost between $7,190 and $9,180 per semester.
Different regions:
In some large cities such as New York, Boston, and San Francisco, the cost of school dormitories is relatively high. For example, the cost of on-campus dormitories for undergraduates at MIT is approximately between $9,000 and $14,000 per year. In some cities in the central region, such as Atlanta and Pittsburgh, accommodation fees are relatively low, and on-campus dormitories may be at an average level or even lower.
In addition, some schools may also require students to pay an application fee and a deposit, and these fees are usually non-refundable regardless of whether or not they move in. At the same time, some schools' dormitory fees may include utilities and some meal plans, but some schools require students to purchase a meal plan separately.
