When I paid a large amount off today, I check the repayment option they have offered to see what is the minimum interest I could pay over the period. In my case, I have 28000 in debt, around 6.5% total APR, this should adds up to $318 per month over a period of ten years. However, the "standard option" they offer is $390 per month, which adds up to 390*12*10=$46800 ! How can this be the case! Are they over collecting the interest? Totally a rip off! Shame on US for pushing college kids into enormous amount of debt at a inflating APR and probably overcharging the interest rate. I mean, 5% of processing fee and 6.5% APR are too much for a loan that is meant to help people to get education!
