It'll depend on the local market. I make about the national average for a DBA with my level of experience, but I live in an area with less than 80% of the national average cost-of-living. Effectively, I'm making a lot more than the national average, because of that. Seattle has a higher than average cost-of-living per Census Bu, so you have to take that into account. Best numbers I could easily find say that you need to make $90k/year in Seattle to have a $70k/year lifestyle, compared to national averages. Same ratio, applied to $120k/year, comes out to about a $97k/year lifestyle. Doesn't work exactly that way, but it's rule-of-thumb-accurate.

So $125k/year in Seattle puts you at the high end of medium of DBA salaries, compared to national averages of income/cost ratios, assuming c. 8-10 years of experience.
