Learn about student loan consolidation.

Know what kind of loan you have. Stafford and PLUS loans that originated before July 1, 2006, are variable rate; on or after that date, they are fixed rate loans. If yours is variable, the rate will reset on July 1 of each year. I recommend waiting until July 1 to consolidate as rates will drop by more than 3 percent, says Mark.

Know the benefits of consolidation.
The main benefit of consolidation, aside from locking in a good rate, is having a single bill and access to different repayment options. But if you have a fixed rate loan, it's better to leave it as is. Mark says most lenders offer unified billing these days, and you can get something like extended repayment without consolidating.

Good debt
Remember that student loan debt is considered good debt in the eyes of creditors, and it's likely to the lowest interest rate you'll ever see on money borrowed. If you have costly credit card or other debt, it makes sense to extend your student loan repayment plan and put the extra cash toward paying off the more expensive credit card debt.
