What are some of the disadvantages of getting a Direct Consolidation loan?

While loan consolidation can simplify loan repayment and lower your monthly payment, it also can significantly increase the total cost of repaying your loans. Consolidation offers lower monthly payments by giving you up to 30 years to repay your loans. But, if you increase the length of your repayment period, you'll also make more payments and pay more in interest than you would otherwise. In fact, in some situations, consolidation can double your total interest expense. If you don't need monthly payment relief, you should compare the cost of repaying your unconsolidated loans against the cost of repaying a consolidation loan.
You also should take into account the impact of losing any borrower benefits offered under repayment plans for the original loans. Borrower benefits from your original loan, which may include interest rate discounts, principal rebates, or some loan cancellation benefits, can significantly reduce the cost of repaying your loans. You may lose those benefits if you consolidate.
