<p>Your aid letter is based on estimates. Once you actually do your taxes, your aid package could change due to changes in income, AGI, taxes paid from estimated to actual.</p>
<p>FAFSA EFC is used to compute eligibility for federal aid. If you are using the same info to complete the FAFSA as you used to complete the Profile, your federal aid eligibility will remain the same … the school would have computed federal aid eligibility using the Profile info. The only “guaranteed” federal aid is the Pell (if you qualify), as well as Stafford loans (which not every college will package into your aid award, but for which students will qualify as long as there is a parent/student contribution not covered by grants & scholarships).</p>
