Ok, so here are some ways to take advantage of the governments revisions to IBR (enacted last December 2012). this is a great deal but it depends on what you want to be making. obviously i support the student loan forgiveness act but i cant see the government being more generous than this (with the caveat that not everyone qualifies for the new IBR and those people still need relief)
also called "pay as you earn". basically, your payments are not contingent on your loan balance - they are calculated off your income. 10% of your AGI over 20 years. after 20 years, your debt is forgiven (10 years if you work for gov or non-profit)
Lets start with the average dude, graduating with $30k in debt, starts out working at starbucks
all of these calculations assume 3% raises (which may or may not be accurate)
The government is giving you a $30k interest free loan for 20 years
Next scenario: Accountant, $50k debt (on the high end), starts out at a Big 4 accounting firm
This person would have been slightly better off paying it over a 10-year plan, where his total payments would have been $69,279 (depending on his time preference).
the more you make, the less you benefit
the real boon here is for grad students.
Now lets look at an MBA grad, making $90k after graduating, borrowing the average MBA debt of 120k. Let's say he also has $30k debt left over from undergrad he never paid off

i was more aggressive and assumed 5% raises, so his final salary at year 20 is $227,425.
although this person ends up paying $75k of interest, its not much over a 20 year period especially for someone making six figures.
also, under a ten year "standard" plan he would have paid $218,390. Why would he do the ten year plan if he could pay almost the same in 20?
Now for the real comedy
A med student who spends 5 years in residency making 50k. He then works at a hospital for 5 years (a nonprofit) making $250k+ (3% raises). Since he works for a nonprofit, he qualifies for 10-year forgiveness.
he borrowed $300k in loans

for shyts and giggles lets say he had 50k left over from undergrad
Here's the catch, the forgiven amount under the 20-year plan is taxed. so you could end up with a tax bill at the end (if they dont change it, which they probably will).
but that doesnt apply to the doctor since you are exempt from forgiven loans being taxable if you work at a nonprofit
the bottom line is that the incentive here is to max out your loans and hold onto your savings. they really need to fix this shyt
