You're right that I was way above the norm. I could probably cut most of that by 75-80% if I had to. But the "norm" there wouldn't be the kind of living I'm used to.
Look, folks, the reality is there are a handful of countries in which you can live like a King for $12,000 a year.
The reason it's hard to get a handle on this is because the life lived is not like what you live now. If you're in Bangkok (not recommended) you won't own a car. The traffic is jam packed and there's nowhere to park. That's $3000/yr in your pocket, plus gas, plus insurance. Transport in general will cost you over that year what gas would have -- but the car depreciation and the insurance stays in your pocket. Don't think of it as some loss of lifestyle. This is how most in NYC live, too. Subway and taxis.
Housing, air conditioned housing with equivalent furniture and internet and utilities in general will be 1/4 of what you're used to -- or rather, for what you need. You may be used to 3500 square feet for 4 bedrooms for the kids, but you won't need that or even want that. Let's phrase it with one more difference -- it will be 1/4 the price of the equivalent square footage in the US.
Food costs less. Services cost less. Medical costs less.
In general, the bulk of pre retirement costs are housing, medical and car. Those get slashed overseas.
