as far as COL goes, from personal experience I'd compare the cities this way:
Stockholm < Helsinki <<< Oslo
Nothing can prepare you for how expensive Norway is. Oslo is ironically cheaper than some other cities in Norway, especially the oil cities where most people are expats (on expat salaries). In Svalbard you'll pay 8 Euros for a 30cl (small bottle) beer.
