This is an impossible question. If you focus solely on money, then I can give a tiny bit of helpful information. As to whether or not being a lawyer will make you happy, that's the impossible part.

Financially, you have to look at it this way.

Monthly Loan Payments on 125,000 of student loan debt. (at 7%)

10 year term: $1,451 per month. ($17412 per year $174,120 over lifetime of loan)

15 year term: $1,123 per month ($13476 per year, $202,140 in total payments over lifetime of loan)

25 year term: $883 per month (10,596 per year, $264,900 over lifetime of loan)

So will a law degree make you an average of $10,596 more per year over your whole life?

I had a job offer before law school to make 45,000 with regular raises, and a cap of around 80,000. If I get an offer from my current internship, I will start at around 65,000 (cap is unknown, but it's higher than my last industry)

It's scary being in this much debt, but I think it will actually pay off in the long run, but not by as much as I thought.
