Your total EFC is $50,000. They split it evenly based on your post.
There are cases where the formula shifts it to one or the other based on things like one living at home and commuting or other things entered.
Remember if one decides to delay a year, then the EFC becomes $50,000 for the one.
Your children will get financial aid packages from the colleges they applied to with various combinations of need based aid, merit, student loans, work study, parent loans, etc…it is hard to compare apples to apples.
If any colleges meet 100% need they will have their own formula and it may or may not get you to $25,000 that they expect you to pay.
If the college is instate and the total cost is $19,000 you would most likely get no need based aid. You would pay $19,000.
If the college is a private college that meets 100% of need and costs $65,000 per year, the financial aid package may be about $40,000. Remember that $40,000 could be made up of a $5000 student loan, $3000 in summer job contributions from student, $12,000 in need based scholarships, and a $20,000 parent plus loan. So you are really expected to pay $25,000 plus take out a $20,000 loan for a total of $45,000 plus interest out of pocket.
Some financial aid packages do not include loans in the need based packages others do.
