How much to charge for graphic designing jobs

I want to know that how much one should charge for freelance graphics designing jobs with all the concept designs. like for brochure, packaging, logo,
poster and ads.[/b]

Totally depends on experience, location, ability, and budget of the client.

Ok but if you are about to start working with a outsourcing company as a freelancer graphics designer who work for US clients then what will be the rates ?
