Right now, it appears that student loan interest rates could rise soon. If you don’t consolidate, your rate is essentially variable.
When you consolidate, though, you lock in your interest rate.
When I finished my graduate degree, I had five different student loans for attendance at two different universities, with various interest rates.
On top of that, most federal student loans have 10-year repayment terms, starting from six months after you graduate from college.
The biggest advantage of federal student loan consolidation is that your monthly cash flow improves immediately.
