With a PhD, I know I'm a lot more flexible in job positions than I ever was with just a master's degree. I expect a higher salary and I got it. However, you are correct, I gave up 2 years of high paying job for 2 years of graduate student salary. I lost ~$65,000 in those 2 years. I also start with 0 years experience, instead of the 2 years experience that I would have had with a master's degree. Will I make it up + interest? Maybe. Maybe not. However, I now enjoy the pick of any job at any location. The job I have is also made much easier since I do much governmental grant research. A PhD after my name gives me a heads up over those people applying for grants without it.
I'm in chemical engineering, so I'll only post data from that field. This data is from my copy of the 2000 AIChE (Ameircan Institute of Chemical Engineers) Salary Survey. This data is the median salary by year of bachelor's degree and by degree (I'm rounding to the nearest $1000 since I'm lazy):
Year, BS Salary, MS Salary, PhD Salary
99, $47k, NA, NA
98, $48k, NA, NA
97, $48k, Not enough data, NA
96, $52k, $50k, NA
95, $53k, $55k, Not enough data
94, $57k, $57k, Not enough data
93, $59k, $56k, $58k
92, $59k, $60k, $66k
91, $63k, $54k, $67k
90, $67k, $60k, $72k
85, $72k, $64k, $79k
80, $85k, $80k, $97k
75, $93k, $90k, $79k
70, $85k, $98k, $140k
65, $101k, $85k, $105k
Mean, $74k, $83k, $90k
Median, $70k, $80k, $85k.
The way the data is set up by year of bachelor's degree, experience is built in automatically. For example, looking at 1990 data, the bachelor's had 10 years of experience and earned $67k, the master's had ~8 years of experience and earned $60k, the PhD had ~6 years of experience and earned $72k.
I skipped many years since I got lazy typing. Out of 33 years of data, the PhD had significantly more salary than the master's in 27 years. In 2 years, they were within $2k. Only in 4 measly years did the masters median salary exceed the PhD median salary.
With a mean salary of $7k more per year, after working 40 years, I very well may make up for the lost $65k at the beginning.
