How much do I need to make per month to live in Mexico City?

I don't know about this guy ^, but I'm an international student and my rent is LOADS cheaper than that. For 4,200 peso's a month, I live right near uni and that gets me three meals a day also. You'll be able to find suitable accommodation at around 4,000 per month, and the rest for expenses. Food is reasonably cheap. You'll do fine.
