You said that one of your kids had $150 more in savings…but you never mentioned their actual incomes or the savings amounts.
What were those incomes…in 2018
ETA…you are talking about FAFSA EFC Numbers, right? Please keep in mind that the EFC is used primarily to calculate federally funded need based aid.
Have you run the net price calculators for your two students? Will they be attending or applying to the same colleges? The net price calculator really will give you a better sense of potential for aid than the FAFSA EFC (unless you are divorced, own a business, or own property other than your primary residence).
