Here in Philadelphia, software developer interns are typically paid $15-25 per hour. Drexel University runs one of the nation's largest coop programs (required work experience as part of the degree), and the employers that work with them to list jobs for students pay an average of $16,000 for 6 months across all majors. Most of the majors with a coop requirement are engineering related, including CS.

One of my friends is now a sophomore at Berkeley with some good hacking skills and he made about 8k/month at a start-up over this past summer in SF. He does iOS and JS.

That would be about $65/hour based on his hours.

The university of Waterloo publishes the salary ranges and averages for its students [1]. You want math or engineering, work terms 4 or higher.

The ranges cover mom and pop shops in small towns as well as big tech companies in Silicon Valley. Hopefully it's a good starting point!

My Coop while I was a Georgia Tech student payed 16.50$ to start out. The people I knew who did some free lance or part time development charged or were payed between 10$ to 30$ depending on their reputation.

I was paid $18-$24/hr as an developer intern in college in Raleigh, NC (about 5 years ago).
