How much money can you earn with a master's degree in social work?

You want to make money out of social work!

Isn't your question a contradiction in terms?

I'm glad that you want to serve your fellow man/moman. It is noble of you and you should be commended. Too many of todays people are only out for themselves.

To answer your question, you can made a living and survive but don't put any money down on a vacation home just yet.
