Not sure what you are asking here. The FAFSA gives a family contribution. That’s it. It’s a financial aid application form not a money awarding agency.
The family contribution is what the FAFSA calculates you can pay for the full cost of attending college. BUT most colleges do NOT meet full need at all for everyone so that number should be viewed as the MINIMUM you will be paying per student.
The net price calculators are a better bet, but as a divorced parent, these might not be accurate, especially for colleges that also require either the Profile, or their own form.
And the CA publics do NOT meet full need for all accepted students.
