This article from the Los Angeles Times can help.
First, it recommends categorizing your student loans:
"If you have been borrowing all the way through school, you probably
have a variety of loans with different interest rates and terms. Before
considering repayment options, you need to examine the type of loans
you have and separate your loans into piles. Gather your documents and
sort them by loan type:
* Perkins loans
* Subsidized Stafford loans (the federal loans that you were granted because you had financial need)
* Unsubsidized Stafford loans (federal student loans that anyone can apply for)
* Stafford loans that you got before 2006.'
Then, it describes repayment options:
"* Standard repayment, which repays your loan over a 10-year period.
* Extended repayment, which allows you to repay a significant balance over as much as 30 years.
* Income-based repayment, which allows you to pay what you can afford, based on your discretionary income."
Finally, here is some expert advice they gathered:
"If you have sufficient income to repay your loans, standard repayment
is the best bet, said Mark Kantrowitz, president of FinAid.org, a
website that explains financial aid options. It gets the job done
fastest with the lowest overall cost...If you need a lower monthly payment, you could choose the extended repayment option and spread your repayment over 25 years...If your earnings are low, income-based repayment could allow you to pay
nothing at all, Kantrowitz said. The catch? There's far more continuing
paperwork with this loan because you have to verify your income each
year. When your income rises, your payments will too."
With the grace period for recent graduate's student loans ending, this is useful advice to be presenting.
