The coroflot salary survey gives you a better idea and breakdown by region, as well as title and employment area (corporate/freelance/consultant).
The answer is going to depend on who you talk to, but the survey gives you a pretty good idea of what you can expect based on where you plan on working, along with a decent ball park for starting salaries. As you can see from the curve, you have everything from students fresh out of school who are making $20k a year scraping by on freelance jobs, to design directors who are making well over 6 figures. Where you want to slot into is going to be a function of your skills as a designer and where you choose to work.
I personally don’t have anything to complain about.
