First of all: There is no right answer to the question of how much a software developer should make. While top tech hubs such as Silicon Valley pay average salaries of up to 120,000 USD per year, developers elsewhere might be working for only 30,000 EUR gross.
This makes estimating the appropriate salary difficult, but there are guidelines employers can use for orientation.
Please note: Present salary report uses several sources, so the data on salaries and salary ranges may vary.
