As a starting point…
A school’s Cost of Attendance (COA) MINUS your Expected Family Contribution (EFC) as determined on the FAFSA = Financial Need, or how much need based aid you can get.
I thought all of the top 10’s met full demonstrated ‘Financial Need’ using this formula as a base. Setting aside the CSS profile for a second, double check the stated EFC on your FAFSA. If the school’s calculation has you paying more than that EFC, there may be an error somewhere in the school’s calculation, or, the school has determined you have a higher EFC than the FAFSA suggests, possibly based on your CSS profile.
CSS profile schools considers the other assets that may be available to pay college costs and may reduce your financial aid such that you are paying substantially more than the EFC per your FAFSA. The previous poster is correct in that it is often home equity that ends up affecting aid. Take a look at this website’s calculator and run it for your school using your parents home equity…the extent to which a school expects parent to leverage their home asset to pay tuition truly varies. I am not sure if this calculator is 100% current (https://www.edmit.me/home-equity-financial-aid-calculator). Some schools cap home equity, some don’t. Good Luck.
