Most designers wonder if they're charging enough. You probably do too. And you probably aren't. Where does your hourly rate come from? Out of thin air? From an industry guide? Is it a number that's close to or the same as what your competition charges? Is it a number you chose because it's comfortable to you and no one complains about it? (By the way, if you're getting every job you bid on, you're probably not charging enough.) Or did you sit down and figure out how much you need to charge in order to earn the living you need and achieve your goals?
