This varies a lot depending on your region, but I'm using data from the Stack Overflow Developer Survey to get to my answers, and the data can be found here: https://insights.stackoverflow.com/survey/2018/#salary.

Developers in the US seem to make anywhere from $90k to $130k but thats just some averages. Newer devs will make less and more experienced devs will make a lot more.

Globally it seems to be less, $51k-$89k.
