it's 50k BEFORE interest. and since you won't be making enough to pay more than the minimum for a while, get ready to live off of ramen for a while. after interest the loan is $121,000.00. in a few years you should be making enough to pay more than the minimum if you balance your budget good, so you shouldn't have to pay the whole $121k, but you can expect to pay way more than just $50k.
