You live at home and received an offer of $73k out of college. The median household income in NJ for a family of 4 is $85k. You’ll be fine. You have no dependents, you have no mortgage. Just save as much money as you possibly can so you can afford a place to live without sacrificing too much when it’s time to move out.

As far as knowing if that’s a good salary, it depends on your degree. If you are a pharmacist you are getting hosed. If you graduated with a marketing degree it’s a good starting salary.
