I haven't moved from ATX to Bay Area, but some co-workers of mine have. Roughly speaking it's about 15-18% increase in cost of living from ATX to SF (overall).

I haven't moved from ATX to Bay Area, but some co-workers of mine have. Roughly speaking it's about 15-18% increase in cost of living from ATX to SF (overall). Unfortunately, my company was only willing to give 7% salary increase for relocating from ATX to SF. Granted, this is only one Fortune 500 company, but it would seem the CNN adjustment is a bit high.
