Probably not common, but that's a little more than I made as a developer 10 years ago at a small company with like 6 employees. It was not a tech company, the CEO knew enough to keep the website running and I did some enhancements. I worked there for almost a year then got a 250% pay increase at a real software company. The owner of the small company said he could not match the salary, and that I would be making more than him. I felt kind of bad, but did honest work during the time I had there and that's all I could do.
