Geographic arbitrage — earning a developed-market salary while living in a lower cost-of-living area — is one of the most powerful financial levers available to remote workers. A $90,000 salary in San Francisco leaves less disposable income than a $65,000 salary in Medellín or Tbilisi. This calculator compares the real purchasing power of any salary across cities using cost-of-living indices.
Example
Base salary: $85,000 (New York) Target city: Lisbon, Portugal
Purchasing Power Formula
Purchasing power = Salary × (Base city index ÷ Target city index) Disposable income difference = (Cost base − Cost target) × 12 Annual savings advantage = Disposable income difference − Any salary reduction
How Cost-of-Living Comparison Works
Cost-of-living indices express relative prices against a baseline city (usually New York = 100). A city with an index of 50 is half as expensive on average. Purchasing power parity applies this to income: if your salary stays the same but your costs halve, your effective wealth doubles. The index covers rent, food, transport, and entertainment — the categories that dominate daily spending.

What about taxes in another country?
Tax residency rules vary widely. Portugal's NHR regime, Georgia's territorial tax, and Estonia's e-residency each offer advantages. Consult a cross-border tax advisor.

Top picks by purchasing power vs. quality of life: Tbilisi, Medellín, Chiang Mai, Lisbon, Mexico City, and Tallinn.
Does this account for healthcare costs abroad?
