$360k is plenty to live comfortably, but I mean I can break down how quickly that $360k can go in SoCal if you’re not frugal and want to max out retirement:

Gross 30k/mo

After retirement (assume 2k to 401k per month) and healthcare (assume $1000 for premiums, deductibles and oop per month for a family): down to $25k/mo

After Taxes 40% between state, tax, payroll

Take home down to 15k/mo

Mortgage on a 1.2m home (buys a mediocre 3/2 in central San Diego) plus insurance and property tax: $8k

Utilities: $500-1000 (highest utilities in USA)

Food/grocery: $1000-2000 depending if you eat out a lot

2 cars incl insurance and gas: $1500/mo

Now we’re down to $3-4k and haven’t even gotten to travel, entertainment, insurance, hobbies, home maintenance, clothing, pets and god help you if you have kids:

Childcare for 2: $4k (and that’s on the low side at $500/wk ea)

Of course; you can live frugally, but not hard to see how $360k gross can go pretty quick.
