The amount of money that the family is expected to be able to contribute to the student's education, as determined by the Federal Methodology need analysis formula approved by Congress. The EFC includes the parent contribution and the student contribution, and depends on the student's dependency status, family size, number of family members in school, taxable and nontaxable income and assets. The difference between the COA and the EFC is the student's financial need, and is used in determining the student's eligibility for need-based financial aid. If you have unusual financial circumstances (such as high medical expenses, loss of employment or death of a parent) that may affect your ability to pay for your education, please tell the Office of Student Financial Services. We can adjust the COA or EFC to compensate.
