San Francisco vs. Seoul: Detailed 2026 Cost of Living & Quality Comparison

San Francisco presents a significantly more expensive cost of living compared to Seoul, particularly concerning housing, dining, and transportation. While groceries are slightly cheaper in Seoul, the overall cost of living index for the city is considerably higher. Basic utilities, mid-range restaurant meals for two, and public transportation fares are all substantially more expensive in San Francisco than their Seoul counterparts. Furthermore, property prices in San Francisco are exceptionally high, with even the city center price per square meter being significantly more expensive than Seoul's averages, reflecting a stark difference in real estate affordability.

Despite the high cost of living in San Francisco, the city offers a substantially higher average net income compared to Seoul. The average monthly net salary in San Francisco is nearly double that of Seoul. This higher income partially offsets the greater expenses, but the city's high property price-to-income ratio (25.6) still indicates significant pressure for many residents, although it is marginally better than Seoul's ratio (27.7). Seoul's lower cost of living, particularly for housing, combined with its robust economy, results in a lower average net income, but the disparity in affordability remains notable.

When evaluating quality of life factors, both cities excel in healthcare and have relatively efficient public transportation systems. San Francisco boasts a higher health care index (85) compared to Seoul's (83), suggesting potentially slightly better healthcare access or quality. However, Seoul's public transport is notably cheaper and more frequent, with much lower taxi and fuel costs. The climate indices are comparable, but San Francisco's higher pollution index (42) is a concern, whereas Seoul's slightly lower climate index (68) might indicate a different seasonal feel or perception.

In terms of economic indicators, San Francisco demonstrates a much stronger performance with a significantly higher GDP per capita ($350,000) and a lower mortgage interest rate (3.99%) compared to Seoul ($50,000 and 3.99%, respectively). This combination of high income, relatively low borrowing costs, and excellent healthcare contributes to a potentially higher perceived quality of life in San Francisco, despite its high cost. Seoul offers a more affordable lifestyle with strong public services and a solid economic foundation, presenting a different, but still high-quality, urban experience.
