Start with the resident or commuter budget
BU Financial Assistance publishes separate 2026–27 undergraduate budgets for resident and commuter students. For most residents, the annual cost-of-attendance table totals 73,024, fees 1,000, housing and food 2,085. The commuter total is 0 for housing and food, 3,935 in incidentals. Those categories are budgeting assumptions, not a quote for each student’s spending. A commuter who pays rent outside BU may have substantial housing expenses that are not represented by the $0 line. The table’s purpose is to support financial-aid budgeting, and the university says tuition and fees can change. Keep the resident and commuter cases separate; do not subtract one total from the other as if the difference were a universal saving. For an international student, compare this cost-of-attendance budget with the separate I‑20 estimate, which uses different assumptions and a different purpose.
Housing and meal-plan scenarios
BU Housing’s 2026–27 rate schedule shows why room type matters. A standard minimum double, triple or quad room costs 7,570, giving a combined 14,020 plus the same plan, or 18,570 before dining, while apartment-style options range from 23,450 for an apartment with one student. The university says apartment-style residents are not required to join a dining plan and that the actual bill depends on the assigned residence. These posted rates are not an off-campus rent survey and should not be used as one. Compare occupancy, location, lease or contract period, included utilities, meal-plan requirement and travel distance to your school. Ask Housing about availability and eligibility for your entry year; the cheapest rate may not correspond to the room or location offered to you.
The I-20 estimate is a separate planning document
For 2026–27, BU’s International Students and Scholars Office lists a 9-month international undergraduate I‑20 estimate of 73,364, university fees 3,715, room and board 1,045, and incidentals $4,992. The ISSO page explicitly says these figures are estimates for I‑20 processing and do not reflect official tuition, fees or living expenses. The insurance figure is based on the 2025–26 Basic rate; special programme fees may apply. This total differs from the resident cost-of-attendance estimate because it has a different audience, period and component basis. Use it to understand the financial documentation baseline for immigration, not as a personal invoice or a prediction of exactly how much you will spend. BU may require funding evidence for tuition, fees and living expenses before it issues immigration documents. Check the current estimate and required documentation for your programme and start term.
Insurance, transport, books and personal spending
The published budgets include allowances that are easy to overlook when students compare only tuition and rent. BU’s undergraduate resident budget includes 2,085 for incidentals. The commuter model uses 2,647 for food on campus. The ISSO I‑20 estimate includes required health insurance and an incidentals category that the page says includes transportation and personal expenses. These are university estimates, not individual spending limits. Your actual transport cost depends on where you live and how often you travel between campus locations; course materials vary by school; insurance coverage depends on the plan and eligibility. Before accepting housing, check which utilities, meals and fees are included. For a personal budget, list recurring costs by month and add one-time arrival expenses such as travel, deposits, bedding and required equipment. Keep the source year beside each estimate and avoid converting the figures into a future-year promise.
Summer study and programme-specific costs
Summer study can add a separate term’s tuition and living costs. BU ISSO’s 2026 summer estimates are 19,115 for two sessions covering twelve weeks. The page says summer expenses should be considered when a student begins during summer, returns from a leave of absence or extends a programme. Summer is optional for many students, but the timing can be required by a particular course sequence or pathway. BU also warns that special fees may apply to specific academic programmes, and first-year College of General Studies students use a different cost-of-attendance page. Students should therefore ask the school how many credits, sessions and additional fees apply to their route. Do not add summer estimates to the standard academic-year total unless your study plan actually includes summer attendance. Confirm whether housing, meal plans and health coverage continue during that period and whether aid applies.
Build a realistic Boston cost comparison
When comparing BU with another university, use matching periods and categories: direct tuition and fees, room, meals, insurance, books, transport, personal spending and any summer term. Label whether a number is an institutional charge, a cost-of-attendance allowance, a housing rate or an immigration estimate. For BU, a 2026–27 resident COA total of 105,666 answer different questions. They should not be added together or treated as interchangeable. If you will live off campus, replace the resident room-and-board assumption with a local housing budget that includes lease duration, utilities, transport and meals; use actual quoted rents rather than assuming the campus rate is equivalent. If you expect a scholarship, subtract only the amount confirmed in writing and verify whether it applies to tuition, fees or another charge. Finally, check the latest BU rates before paying a deposit, because tuition and housing prices can change from one academic year to the next.
