So here's my estimation of what I think is a typical monthly budget for family of 3:

Rent: 0 - family owns the house
Groceries: 6000
Cooking Gas: 1000
Water: 1000
Electricity: 1500
Telephone (landline & mobiles): 1500
Transportation (public): 2000
Eat out: 2000
clothing: 2000
Entertainment (movies, cable tv, etc.): 2000
healthcare: 2000
Incidentals (repair, gifts, whathaveyous, etc.): 2000

Total: 23,000

I see above as reasonable budget.  Tell me if I am off the mark.  I have not included the child's tuition, fees, etc. as I do not know how much a typical school costs. 

What do you think?
