I generally do my finances month to month, soooo:
$16,000 per month
$11,500 left after federal and social.
~$10,000 left after California takes its pound of flesh
$1100 for rent (I am frugal and live with a roommate), utilities, cellphone
$170/month for health insurance, $25 a month for motorcycle insurance
Rounding monthly spending up to $2k.
Roughly $8000 left over at the end of each month, meaning I stack up about ~3 months of runway for every month I work.
My biggest indulgence/non-required expense is Instacart. I justify the expense of Instacart as a way of incenting myself to cook from home. (And I do.)
A salaried programmer out here, if they live by themselves and eat out often could quickly find themselves living paycheck to paycheck. God help the people that have families, you need both parents working (now you're coping with the cost of child-care).
Here's how somebody else's story out here looks:
$90,000 a year in salary
$5,500 a month in take-home after taxes.
$3,000 for rent and utilities for a two bedroom apartment for the wife and kid (most people out here have fewer kids. Can't a afford a house for more than one or two).
$600 a month in groceries for a family of 3. If the programmer resists the peer pressure to eat out, the food costs can be constrainted to this.
$1,900 in slop month to month so far.
$150 a month in health insurance premiums (insuring a family is expensive)
$400 a month in car payments + insurance
If any of them are commuting any distance, easily $100 a month in gas.
$1250 left per month.
And you haven't bought your kid any clothes yet.
If you want a decent house in Mountain View (where I live) or Palo Alto you're generally looking at at least $1 million.
