Quite a few developers I know save more than 50% of their after tax income. If you look at mrmoneymustache.com the vast majority are software engineers and other technologists. It's probably due to that introspective nature that developers typically have. Our needs are often fairly modest. We're pretty happy to have shelter, food, internet, computer, and eat out a few times a week, etc. They are making under $100k too, and putting away $30-40k/year. They started working at 21-22 years old and the time they hit 30 years old, they've probably ended up close to $500k assuming their investments compounded.
