Three of us in the household.
Mortgage + P tax :3600
Utility (plus phones): 600
Daycare: 1300
Donation and life insurance: 500
Grocery + clothing + gas + blabla = 3000
Extra spending :1000 (vacation, house maintainance and so on).
Total: 10000 a month
We only bring home 11000 amonth after 401K, tax and health insurance. We also have some extra bonus in the end of year but hard to depend on it. Life if expensive and it is hard to save. Maybe we just making too little.
