The nonprofit research organization Hildreth Institute released three reports from its Cost of Attendance Transparency Project on October 20, 2026, comparing the housing, food, transportation, and other living-cost estimates published by 5,235 colleges, and found that colleges in the same local area often publish markedly different figures. For Irvine families now comparing early-application colleges by cost of attendance and net price, the research is a reminder that differences in the living-cost line do not necessarily reflect differences in actual expenses.

Who Is Affected by Uneven College Living-Cost Estimates

The families affected are those of 12th graders who are comparing college costs and preparing financial aid applications. Federal law requires a college’s published cost of attendance to include estimated housing, food, transportation, and other living expenses, including for students living off campus. These figures are estimates, not charges the college actually collects, but they set the limit on financial aid and underpin measures such as net price and unmet need. The press release notes that in most sectors studied, tuition accounts for less than half of published cost of attendance.

The reports have three main findings:

  • The pattern is inconsistency rather than uniformly high or low estimates. Colleges in the same local market can publish very different living-cost allowances, while others report identical amounts in places with very different costs. Nationally, above-benchmark estimates are more common, but substantial below-benchmark estimates remain, and fewer than one-quarter of institutions report totals close to the benchmark.
  • Setting one living-cost budget for an entire student body is difficult. Colleges must make choices about data sources and housing and transportation assumptions.
  • Standardization does not guarantee accuracy. State- or system-level methods improve consistency but do not necessarily better reflect local costs.

The reports also state that the benchmark is a common reference point, and that a difference from it does not show whether a college’s estimate fits an individual student’s needs.

What to Do About College Living-Cost Estimates Now

Break down the cost of attendance before comparing. When comparing two colleges, look at tuition, housing and meals, transportation, and personal expenses separately. At the University of California (UC), for example, the published 2027–28 average costs for California residents list tuition of $16,278, campus housing and meals of $21,700, and off-campus housing and meals of $20,400; books and supplies are $1,400, and personal and transportation expenses are $3,900 on campus and $4,800 off campus.

Adjust living costs to the family’s own situation. Living at home in Irvine and commuting, living on campus, and attending college out of state lead to very different living costs. When using each college’s net price calculator, replace the living-cost line with the family’s own realistic expectation before comparing net prices.

Living-cost estimates affect the financial aid limit. A college with a low living-cost estimate may also calculate lower need and lower available aid. After receiving admission and aid offers, a family whose actual expenses are clearly higher than the college’s estimate can explain the situation to the college’s financial aid office.
