This is a common question that people ask and I get a few people emailing me about this too. The trouble is no-one wants to tell you it’s a taboo question to talk about wages. I remember when I started out freelancing I was fairly lucky as I had previously hired freelance designers (when the company got busy) and knew the kind of going rates that I could charge. One way to find out average design wages is to look at the jobs section of design magazines or design recruitment websites.
