My calculation is 1.5M!!! Suppose you have 2 kids and you are in your 30s or 40s. To invest 1.5M in funds, it's not too difficult to get 8% return, right? I get more than 8% dividend. I did't even consider the appreciation. So you have $10,000/month income. Here are the expenses:
$2,500 rent in Pleasanton or San Ramon. No need to live in PA or Cupertino since you don't need to communte
$175 car (insurance&gas). One car is enough since you and your wife don't work. LOL
$75 tv/inet
$50 cell phone. One phone is enough. LOL
$125 pg&e
$75 water/trash
$1,000 kids education (piano, violin etc.) Use public schools, which are not bad
$250 cloth. Don't buy name brand stuff
$1,000 food. Try to cook more at home
$1,000 health insurance
$700 entertainment (good for 1 trip to China)
$3,000 tax (Uncle Sam wants your money)
Total expenses: $9,900/month
Save $100/month
If you can earn 10% (which is my goal by the way), then 1.2M can get you a comfortable life in silicon valley... hahaha
Any comment?
