Most Expensive Cities by Cost of Living Index 2026

About This Dataset

Cities ranked by overall cost of living index in 2026 according to Mercer Cost of Living Survey and ECA International data, benchmarked against New York City as the reference city. Hong Kong and Zurich compete at the top of global cost of living rankings — with expatriate accommodation, international schooling, and consumer goods commanding prices that make them among the most expensive places on Earth for internationally mobile workers, even before the extraordinary property prices that characterise both cities.

✨ AI Insight

The stark differences in the cost of living indices reveal a competitive landscape among the world's most expensive cities. Hong Kong and Zurich dominate with indices of 127 and 124, respectively, reflecting the high costs associated with expatriate accommodation and consumer goods. Geneva, at 121, also showcases the financial strain on residents and expatriates alike. In contrast, cities like Singapore and London, with indices of 97 and 89, respectively, suggest a more manageable cost of living, although still high by global standards. This trend indicates that while certain cities continue to escalate in living costs, others may offer a slight reprieve, potentially influencing migration patterns for international workers.
