I live in SF and make 140 k$/yr in pretax income.

On a per month basis:

  * 11.67 k$ in pretax earning

  * 7.85 k$ in posttax earning

  * 4.85 k$ in savings

    * In order, maxing out Roth IRA, then Roth 401k, then non-tax-advantaged brokerage account

  * 3 k$ in spending

    * 1 k$ in rent + utilities (I live in a dump with 3 roommates)

    * 400 $ on food

    * 300 $ on transportation

    * 1300 $ on miscellany (entertainment, clothes, travel)

I could probably put effort into tracking that last item better, but I'm happy enough just tracking the top line.
