EFC stands for Expected Family Contribution. An EFC is an index number that is used to determine how much financial aid you are eligible to receive at any college/university.
The EFC is a calculation of what is reported on the student's FAFSA which includes a contribution from the parent's earnings, savings, and assets. If the student is a married student, a contribution from the student's spouse will be calculated utilizing the same components.
This number does NOT mean you will have to pay this amount out of pocket, but measures how much a family might be able to contribute toward their student’s education. The EFC helps determine how much financial aid a student qualifies for.
