<prompt> Human: Currently live with my SO in PHX at a place paying about 1200mth with rent and utilites. We both make about 30k before taxes. When we graduate, she wants to pursue an opportunity with her employer at their headquarters in San Fran 60k. And I would follow suit, making about the same with another company. From what I understand, the cost of living is roughly doubled, with everything factored in. We would like to fully analyze costsbenefits of moving -wise. What are all the different things that we should be taking into account when we are adding up costs including things like retirement.I would like to avoid saying whoops, guess we forgot that state tax is x times higher here... or something similar as we sadly drive back to live at our parents places. If you have a similar experience, please share it!  <response>: I think one thing I would consider is also how stable you think your jobs will be and how much of an emergency fund you have. One big problem moving to a high COL city is that a 6 month emergency fund in case you lose your job in PHX will only last 3 months in SF.Edit: one other thing to keep in mind is that first and last month and security deposit on a 2500 1br in SF is a much bigger hurdle than 1k or whatever the rent portion is of that 1200 in PHX.
