This would have been a great resource except that it is presented as an XLS spreadsheet.I really don't find it convenient to download and few such information in a spreadsheet. The use of a few table tags and presented it directly on their website would have been an interesting and useful resource.
As a spreadsheet it is just a waste.
p.s. So you don't have to waste your time they come up with a monthly budget of US$2171 a month, though I haven't a clue as to what area of Brazil it relates to.
Some things I suspect are high.. $50/month for haircuts and others low $316 for rent.
