Rent= $1200 big kitchen, living room big, 1 bedroom, 1 bath. We are lucky, the standard prize would be between 1500 and 2000 per month ($: pesos argentinos)

electricity+natural gas= $100 a month

healthcare=$600 for 3 persons in the family with discount for my work company (very good OBRA SOCIAL swiss) normally at least $1000. Cheaper OSs can be obtained starting at $70 per person.

car fuel= average I have a gas natural comprimido(GNC) or nafta engine(I choose with a switch). In the city there are 3 GNC stations. 200km costs $18 aprox, that is around 17m^3 of GNC. The nafta liter is $3, so the GNC option supposes a lot of saving.

oil change for the car every 10000 kms around $120

buffet in the work meal: $12 the lunch.

food, cleaning stuff per month(family of three): not less than $1200.

milk liter $3. (idem nafta of course)

bus from home to work (12 km ride) $1.6

daycare: at least $600 (whole day care)

I think that for living (couple and a child) would need at least $4000. It can be done with less than that....
