Tehran vs. Seattle: Detailed 2026 Comparison

Tehran, with over 14 million inhabitants, contrasts sharply with Seattle's population of approximately 3.5 million. Tehran's cost of living index stands at 22.81, significantly lower than Seattle's 90.05, indicating vastly cheaper basic expenses globally, though these expenses remain high relative to local incomes. Quality of life metrics also differ starkly, with Tehran scoring 66.69 and Seattle 189.22, reflecting significant differences in safety, health, environment, and infrastructure.

Economically, the gap is pronounced. Tehran's average net monthly salary is $1,000, substantially lower than Seattle's $6,535. This purchasing power gap largely explains the difference in cost of living indices. Tehran's GDP per capita is $16,000, significantly lower than Seattle's $74,600, reflecting the city's position in a developing economy versus a major developed economy.

The disparity in costs is particularly evident in housing. Rent for an 85m² apartment in Tehran's city center averages $1,000 per month, compared to $2,500 in Seattle. Property prices per square meter are also considerably lower in Tehran ($1,000) than in Seattle ($7,705). Mortgage interest rates are lower in Tehran (6%) than in Seattle (6.46%).

Quality of life in Seattle is considerably higher across multiple dimensions. Safety is a major differentiator, with Seattle scoring 44.82. Other metrics like environmental quality and infrastructure also favor the American city, contributing to its much higher quality of life score compared to Tehran.

In summary, Tehran and Seattle represent fundamentally different economic and quality-of-life environments. Tehran offers significantly lower costs but operates within a developing economy with a much lower average income. Seattle, while more expensive, provides a higher standard of living supported by a developed economy and infrastructure.
