I am in a little dilemma. Hope your experience and some information from you will help me make proper decision. So, if you can, please provide information you have.

I am trying to do a cost-benefit analysis on whether or not to pursue PhD. With Masters degree in Computer Science, I can work for an industry and can earn at least around 80K a year. If I decide to puruse PhD, even with full scholarships and stipends, it will take 4 years, but it will cost me 80k X 4 yrs = 320K since I will not be working. I am not sure about salary for entry level professor (assistant professor, I believe). Let's say it is 100K for computer science... Then to offset my 320K, it will take additional 16 years to make up for the difference. What's your suggestion ? Do you know what entry level computer science professors are paid in United States ?
