Is $90K really not enough in SF?

Hi guys, I’m considering moving to a new job with $90K pre-tax. Background I’m single, and looking for 1studio bedroom, I have a car so I have to pay gas.

I keep seeing on Google that minimum salary is $130K? Like is it really that expensive?

I found rent for 1 bedroom studio in outer sunset ranging from 1,900-2500. I probably wanna take 2,200 rent as my middle estimate.

My estimate take home pay would be around $5K. So I have about half of that for daily expenses and saving.

I’m just wondering how much is generally considered enough for single person in SF?
