Editing to say that if you make the military a career, you can literally save almost your entire salary if your personal peccadilloes are minimal. I knew guys that decided 4 years was enough and emerged after 4 years with over 50k in savings while paying nothing and they also got the BA/BSc degree on Uncle Sam's dime. They emerged debt free, degreed, and ready to start the next stage of their lives. Doing 8 years gets you a masters all the while doing nothing but work a job with everything paid for. At that rate, you might as well do 20, marry another member and have a steady retirement at 39 or 40 with money enabling you to pursue a job you really love because you can afford to live where you want. Bonus: Tri-Care military medical costs $500 year on retirement. Cannot touch that out here.
