Entry level median salary for devs without higher education from the year I left recruitment (2013/2014) was 28000 USD per year. Add 3000 USD for entry level devs with university/college education.
YMMV but I don't think things have changed that much since then.
I had a look at some old notes and stats from 2012-2013. Knowledge in JS, Php, Java, Python or C/C++ were required for all of the positions.
14 recruits in the 18-20 yr, no edu bracket (high school dropouts/just graduated), mean salary 24451 USD (199200 SEK)
24 recruits in the 18-20 yr, bootcamp/vocational edu bracket (high school dropouts/just graduated), mean salary 27249 USD (222000 SEK)
17 recruits in the 20-22 yr, bootcamp/vocational edu bracket, mean salary 28869 USD (235200 SEK)
29 recruits in the 20-26 yr, higher edu bracket, mean salary 34467 USD (280800 SEK)
These were placed with employers, startups and established companies, in the tech sector. Mainly in central Stockholm and Kista (tech hub outside of Stockholm).
Make what you will of this, the amount of job seekers with bootcamp/vocational education hasn't gotten less than in 2012/2013. I believe this keeps the salaries in Stockholm down, and makes you settle for less if you want the job at all. Entry level salaries for devs in Stockholm are low.
BUT - as soon as you get some experience under your belt, you can rise quickly in salary by job hopping for a year or two.
