The Design Price Formula

I pulled this from David Airey's site because pricing is something that I've been think about alot lately. Recently I interviewed for a job where I would be designing logos initially and later on fliers, posters, brochures, etc. But when we talked about price we touched on it, but we really didn't go into too much details because pricing presents its challenges. Hopefully using this formula and using what I learned from researching will help me come up with a price and contract that is suitable for both parties.
