Every time a freelance writer posts anything relating to salary, they also post many qualifiers. I do it, too-- always noting that I work about 60% of full time, or some other such thing. That's because it's hard to talk about what you make. I get that.
So, today, for the sake of new, young freelancers, I'm just going to put it out there: I make about 40K a year.
Other than wanting to give "full disclosure," what inspired this post was the salary survey at Freelance Writing Gigs. I like when bloggers run these things (Freelance Switch did one a year or two ago), as they are a valuable snapshot of the career. I hope you will consider taking that survey!
