You can consolidate all, just some, or even just one of your student loans.
Since you must select a repayment plan on your application, start by determining which plan makes the most sense for your situation.
You may be able to consolidate private loans through a private financial institution, but this is not generally recommended.
A federal Direct Consolidation Loan has a fixed interest rate based on the average interest of your federal loans rounded up to the nearest one-eighth of 1 percent.
Repayment generally starts within 60 days of the disbursement of your loan, and the repayment term can range from 10 to 30 years, depending on the repayment plan you select, your additional educational loan debt, and the amount of your consolidation loan.
In order to consolidate your federal loans, you must be either in your grace period or repayment period.
