Pick any two of 30 cities worldwide. See the monthly gap, a full category breakdown, and the visa and tax reality of each — instantly, side by side.
"Cost of living in Thailand" hides enormous variation — Bangkok and Chiang Mai can differ by 30-40%, and the same is true within any country. Comparing specific cities gives a far more honest number than comparing countries, because rent, the single biggest line item, is set city by city, not nationally.
This tool breaks each city's comfortable monthly budget into rent, food, transport and other costs so you can see exactly which category drives the gap — often it is rent alone, which means a smaller apartment or a different neighbourhood could close most of the difference without changing countries at all.
Visa and tax rules matter just as much as the sticker price. A city that looks cheap on paper can be a dead end if the visa only allows 90 days, or expensive if you are a US citizen still taxed on worldwide income wherever you live. Check both columns before you get attached to a number.
