What salary--this is a good question. Aside from looking at salary
    surveys, I would take into consideration the cost of
    living in your local community:

    For example:

    What is the rental cost of a one bedroom apartment in a
    decent neighborhood?   What is the average cost of a car payment?
    And so forth.  I would recommend that you put together a cost of
    living budget for your community, taking into account extra for
    savings, recreation, etc.  This would make a likely post tax
    salary that the average person could live on comfortably.

    Just my two cents and glad you asked.
