I get similar numbers to @politeperson.
AGI 250K, one earner, family of 3, non retirement cash/savings $75K, gives $25K in institutional grants.
$75K. I don’t know what proportion, but I expect it’s not an insignificant number of families with college age kids (lived thru great recession) that have limited savings, even at that income. It doesn’t matter why, but that’s the reality for some.
Most schools are not as generous as Princeton, which is arguably the most generous.
