How much will I be paid for a phd in finance?

Question

for preparing a phd?

for having a phd?

Answer 1

Depends on how much minimum wage is when you graduate.  

Answer 2

You will not be paid for having a phd. You will be paid for what you can do with your phd.

You will need to sell yourself to someone who is willing to pay for your knowledge. So if you do not do a good job of convincing someone that you will be able to make money for them, you will get nothing.

The more money you make for someone else, the more money you will make for yourself.

Start learning to sell, or teach at the college level.
