hehe! We have almost 300K in student loans for my hubby! Talk about making you wanna be sick!
The last thing you should worry about, given that you have a tight budget, it trying to pay the student loans off early. The interest rate is so low that it's not a huge deal. My husband's boss made plenty of money where he could have paid off his loans early but financially it made more sense to use the money in other ways.
Put that extra money toward other things that have more meaning on your total money picture like credit card debt, other loans, and putting extra toward your mortgage (if you have one).
