5Stockholm – CPI 0.934
Stockholm has been an important economic, political and cultural center ever since the mid-13th century.
The Swedish capital is home to many high-tech companies such as Ericsson, Electrolux and IBM.
And you already figured it out that all major Swedish banks such as Skandinaviska Enskilda Banken, Handelsbanker and Swedbank are headquartered here.
While the city is obviously expensive, some prices come as a shock. Rent is actually cheaper in Stockholm than in Helsinki. Alcohol and groceries are all cheaper than in Olso.
