Quite the interesting article. Major points:
‘… most expats could live comfortably in Vietnam for about $800 to $1,200 a month.
… consumer prices, including rent, are 47.11% lower in Vietnam than in the United States, grocery prices are 45.42% lower, and restaurant prices (especially important if one of you—or both—says he or she is sick of cooking) are a whopping 72.21% less, although one example they cite, a meal for two in an inexpensive restaurant is, at the equivalent of $1.85, a significant 85.66% lower!’
