It depends on several factors, but you can pay off your loans (a little bit), only do so if you understand the rates, deferrment, and taxes.
I've been able to pay back $7,000 this year so far, and plan on $10k by the years end.
I have multiple loans, but the rates are low on all of them except for 1 at 7% and accrues interest while in deferrment, so it makes sense to pay it off as I would probably break even with an investment over 3 years if it beat 7% (w/fees and all).
Once I have paid off the 7% loan, my others are around 2-4%, mostly subsidized, and in deferrment, so it makes no sense to pay them off, and instead place the $$$ in a mmf or CD's.
....long story short, I take home around $2300/mo, and have paid off $7k. Don't forget that if you do your taxes correctly during your first year, you may get anohter $2k+ back in a tax return (different conversation).....and for that matter cost of living, debt, etc.
