Well, looking at UCLA, students come out making $115K salary per year on average in the technology industry. They also get $5,000 signing bonus and $20,000 guaranteed bonuses. So a year 1 take home of $140K.
Payscale also runs a "20 year median" survey... UCLA grads can expect to make $2.6M over 20 years. If I were you, I'd do an Excel for your career trajectory now and compare it (factoring in 2 years of lost salary and tuition).
Also, look through Linkedin or other places for people with the jobs that you want. What's their background like? And look for the average - not the Bill Gates and Mark Zuckerbergs of the world.
