How much FAFSA for financial aid will I be qualified for ? TOTAL INCOME 80k? 7 PEOPLE IN MY FAMILY?

I'm a high school junior but recently I've been freaking out about financial aid and wanted to know your estimates about how much financial aid I would be qualified for (need based, not academic). My family has never been wealthy but not very financial unstable (I've never really needed to figure out where my next meal was coming from). My parents combined income is no more than 80k and there's seven people in my family, including my older sister who is currently in college. She has taken out loans and has 2 jobs (I'm planning to do the same). My parents work crazy hours and lots of overtime just to provide for all five of their kids and so on paper it looks like they make a lot of money, but they virtually have no savings. I know it's depends on a lot of factors but how much would I possibly be able to get if I'm applying to all public universities in my home state? THANK YOU SO MUCH!!!
