The data is based on what the companies advertise, and the data size is of around 2000 salaries for each country:
- Switzerland: https://swissdevjobs.ch/salaries/all/all
- Germany: https://germantechjobs.de/en/salaries/all/all
- UK: https://devitjobs.uk/salaries/all/all
- Romania: https://devjob.ro/en/salaries/all/all
Important to add that we don't catch the whole spectrum of the market (missing FAANG-like and some top international startups), so basically our 90 percentile will be probably an 80 percentile if you add those.
I think it's important to also have this perspective, because not everyone has the determination & luck to go through the whole interview process at FAANG-like companies.
Interesting. The avg salary after tax in romania is 11k ron, around 2300 eur. Tax and national insurance for permanent employees in that country is around 45-50%. So the average pay is around 4400 eur. More than the german average of 45k per year before tax.
