I'm curious how that works for New York City. That calculator gives quite a range. For what I make in a small town in the Pacific Northwest, it says the equivalent is something like $110k in Queens, $120k in Brooklyn, and $160k in Manhattan (I don't remember the exact numbers).
From what I've read, New York has really good public transportation, so one could live in any of those areas and work in another of them reasonably. How does that affect what companies actually pay there? Are salaries in Manhattan actually higher in accordance with the Manhattan cost of living, or does the presence of nearby, cheaper, areas bring the pay down?
