Can Someone Explain the Difference Between Federal Methodology and Institutional Methodology Financial Aid? - differences between federal methodology and institutional methodology

I have tried to use the query EFC calculator, and always ends with 0, then I'd contribute a little to the institutional methodology in the final. I'm confused, where the Federal Republic of methodology ceases to draw their numbers against the institution.
If 0 does not pay or I get any help?
Federal method is not only more when you pay more taxes on IE (rich)?

Thank you!
