What is a good salary for a family of four?

-In the Pennsylvania/Maryland area. Living comfortably but with extra money to save and not be stressed. I'm not talking a ton of money but enough so my family has what they need, a good amount of what they want, my saving's account is profiting, and we have a little vacation money.I suppose that depends on what you consider to be "comfortable". I raised a family of five on less than $60K a year. We never had a lot of money for extras, but the three kids were always clean, happy and well fed, and they all went to college.
