As per http://www.dwheeler.com/sloccount/sloccount.html:

  "The default annual salary is $56,286 per year; this value was from
the ComputerWorld, September 4, 2000's Salary Survey of an average U.S.
programmer/analyst salary in the year 2000. You might consider using
other numbers (ComputerWorld's September 3, 2001 Salary Survey found an
average U.S.  programmer/analyst salary making $55,100, senior systems
programmers averaging $68,900, and senior systems analysts averaging
$72,300)."

Those are numbers from 15 years ago.

Taking the same source, but from last year, gives a programmer/analyst
base salary of $73463.
