Cost of attendance.
In plain English
Cost of attendance, or COA, is the total estimated price of attending a school for one year, set by that school. It bundles direct charges like tuition and fees with indirect costs like housing, food, books, supplies, transportation, and personal expenses. COA matters because it is the ceiling for your financial aid: schools subtract your Student Aid Index from the COA to estimate your need, and your total aid (grants, work-study, and loans) generally cannot exceed it. Because it includes living costs and not just tuition, the COA is usually larger than the tuition bill you picture.
01Why it matters
The COA, not the tuition sticker, is what your aid is measured against, so it sets the real size of any gap you'll need to cover with savings, work, or loans.
02The math, step by step
A school might list tuition and fees at $12,000 but a full cost of attendance of $28,000 once housing, food, books, and transportation are added. Your aid is built against that $28,000 figure, which is also the most you could borrow in federal loans for the year.
03What this is NOT
Cost of attendance is not just tuition. It includes living expenses like housing, food, and books that you may pay out of pocket rather than to the school directly, so it runs higher than the tuition line alone.
