"I'm not paid what I'm worth." Who hasn't said this at least once? I certainly have. But if we subscribe to classical economics which says that the price paid for any given service is the price at which the quantity supplied equals the quantity demanded, aren't we paid precisely what we're worth? And if we still believe we're trading at a discount to our intrinsic value, is it possible to change the market's mind?
I've been a freelancer for more than 25 years and one thing I can tell you about this topic is do not compare your fees to others. You'll always find someone who gets more for less and this will tick you off. I made a point of asking what I wanted and NEVER ever tried to discover my colleague's rates. It's not about price it's about value ... And whether you do. Calculate what $ you need and want then ask for that. The rest be damned. That's their issue - not yours. I assure you that this approach will make you happier and more content. Sure sometimes you'll find out someone got more than you - so what? Big deal. Ask better next time.
