The costs of living in Sweden for a student are estimated by the Swedish Migration Board to be SEK 8,064/month. If you are required to have a residence permit before moving to Sweden, you need to show that you have this amount of money for each month you plan on studying in Sweden. If you do not show you can support yourself financially for your entire stay, the Swedish Migration Board will not grant you a residence permit. For more details about this process refer to Residence Permit.

Full-time studies require 40 hours of work a week and are difficult to combine with part-time work. Opportunities for part-time work in Sweden are limited and most jobs require knowledge of Swedish. International students are however allowed to work while studying. Residence permit for studying also includes a work permit.
