is there a website where i can look up what is the minimum and max a family of 4 should be making ?

Answer 1

Making for what? To qualify for government assistance?

Answer 2

Well, wouldn't that depend on what profession any wage earners are making? Try this site: http://www.bls.gov/bls/blswage.htm . That's the page for the Bureau of Labor Statistics, by area and occupation. Then, all you have to do is look it up by what job the workers in the family have, and total that up.
