https://www.numbeo.com/cost-of-living/compare_cities.jsp?cou... says Zurich is 33% more expensive and I remember it that way.

Numbeo shows averages, and the basket of goods that it considers is not what a well-off person would buy. I Zurich I could live perfectly well without having a car, just with public transportation, and French and Italian cheeses and wine are a cheaper than in Seattle.
