Is two-fold:
First, and most importantly, did it aid you in securing a position that you wanted?
Second, and not very important to the question you asked (or really, to the real world at all asides from personal satisfaction), do you feel you learned enough to justify having gone through the program (nothing worse than forking over $20K+ in order to learn that 2 + 2 is always 4)?
Looking at the first question, my suggestion would be to first identify what you want to do. Next, once you have an idea of what you want to do, peruse some job boards, and look up the position type. See what positions are out there, what the salary range is, and what are the requirements for the position.
Once you look through enough postings, you should get a good idea of what it would take to give yourself a realistic chance at the types of position you want.
Another suggestion would be to take your undergrad degree, and begin working at the lower rungs in the general field of your interest for a company that offers tuition reimbursement. Use that tuition reimbursement to help defray the graduate school costs. That way, when you've completed the graduate program, you'll have a more attractive combination of experience and formal education.
That probably wasn't the concrete response you had wanted. Hopefully, it is of some use, regardless.
Best of luck!
