cost of living is as fascinating to me now as when I began traveling, especially considering how little the cost of living correlates to the standard of living. quality health care, utilities, building materials, ,organic foods, vehicles, electronics, everything is cheap or expensive largely dependent on where you are standing.
I began traveling with only a few hundred coming in a month, so cost somewhat determined my lifestyle. I backpacked more, hostels in SEA are $100 a month still today, and I stayed in those, but at that time I also lived in Ireland, Germany, Italy, Australia, and just paid a little more for private rooms or hostels rather than larger private apartments, which is what I primarily rent now.
If you can bring in $500 a month, you're good in half the world; $1000 a month, you're good to live in most countries in the world, so after budgeting for a year,and understanding the real cost of living, I invested much more and built up my passive income past that point. No bills, no maintenance fees, no insurance required as a traveler, so reaching $500 and then a $1000 a month is very doable.
Even at $500 a month, you can live comfortably in well over a hundred countries, and I've still only been to a few dozen.
If you have any questions, please ask away.
