The cost of living in Sweden is similar to many countries in Europe and North America (slightly less expensive than some and slightly more expensive than others).
For example, rent for small student accommodation (10 – 30 sq. m.) ranges from 3500 – 5000 sek/month incl electricity, water and heating. Larger apartments in Karlskrona (45 – 65 sq.m.) may cost in the order of 4500 – 6000 sek/month. A nice lunch at the student cafeteria will cost about 65 sek and a monthly pass for the local transit system is about 380 sek/month. As of October 2022, 1 USD equals approximately 11.26  Swedish Krona (SEK). The Swedish Institute also provides information about the cost of living in Sweden.
