There are a number of factors beside income that go into the formula for calculating the EFC (the number that determines your eligiblity for grant aid). For example, the number in the household, the number in college, assets, child support received or paid, contributions to retirements funds, where you live, taxes you paid, whether there is one wage earner or two, etc. Because the amounts for each of these things can influence the outcome, there is no specific income levels that are used to decide financial aid. For example, two families could have the exact same income, but if there are more members of the household in one family, then the eligibility for aid could be very different. The purpose of the FAFSA is to determine the parent's ability to pay for college, and a lot of factors beside income can influence that, so there is not hard and fast cutoff in terms of income.
