This weighted average, 6.2%, is then rounded up to the nearest 1/8th of a percent, yielding a consolidation loan interest rate of 6.25%.
Note that the weighted average does not fundamentally alter the underlying cost of the loan. It preserves the cost structure by including each interest rate to the extent that it applies to part of the overall loan balance. For example, the consolidation loan in the previous paragraph says that of the $15,000 consolidation loan balance, $5,000 will be at 5.0% and $10,000 at 6.8%, yielding an equivalent interest rate of 6.2%.
If you are consolidating loans with different interest rates, the weighted average interest rate will always be in between. Don't be fooled if someone tries to suggest that this will save you money by getting you a lower interest rate. The interest rate may be lower than the highest of your interest rates, but it is also higher than the lowest of your interest rates. More importantly, the amount of interest you pay over the lifetime of the loan will be about the same.
(For the mathematically inclined, there is a slight difference due to the different shapes of amortization curves at each interest rate. In the example given above on a 10 year term, $10,000 at 6.8% has a monthly payment of $115.08 and total interest paid of $3,809.66, $5,000 at 5.0% has a monthly payment of $53.03 and total interest paid of $1,364.03. If you add these, you obtain a total monthly payment of $168.11 and a total interest paid of $5,173.69. Using the weighted average, $15,000 at 6.2% has a monthly payment of $168.04 and a total interest paid of $5,165.01. So using a weighted average yields a very small reduction in the monthly payment (in this case, 7 cents) and in the total interest paid ($8.68) due to a kind of triangle law. Of course, when you consolidate the interest rate is rounded up to the nearest 1/8th of a point, so $15,000 at 6.25% has monthly payments of $168.42 and total interest of $5,210.42, yielding a slight increase. So you pay a tiny bit of a premium for consolidation, due to the rounding up of the interest rate.
The PLUS loan interest rate loophole can reduce the interest rate on 8.5% fixed rate PLUS loans by 0.25% through consolidation.
If you were deferring the interest on an unsubsidized Stafford Loan by capitalizing it, most lenders will add the capitalized interest to principal when you consolidate. (Lenders can capitalize interest at most quarterly, but most capitalize it once when the loans enter repayment or at other loan status changes.)
No Cost to Consolidate
Aside from a slight increase in the interest rate on the consolidation loan, there is no cost to consolidate your loans. There are no fees to consolidate.
Under no circumstances pay a fee in advance to get a federal education loan or consolidate your federal education loans. There are no fees to consolidate your loans. While other federal education loans, such as the Stafford and PLUS loans, may charge some fees, the fees are always deducted from the disbursement check. There is never an up front fee. If someone wants you to pay an up front fee, chances are that it is an example of an advance fee loan scam.
Who Can Consolidate
Both student and parent borrowers can consolidate their education loans. (Students and parents cannot combine their loans through consolidation, since only loans from the same borrower can be consolidated. But they can consolidate their loans separately.)
Married students are no longer able to consolidate their loans together. This provision was repealed effective July 1, 2006. When married students consolidated their loans together, each spouse became responsible for the full amount of the loan, and the loans could not be separated if the couple got divorced. To avoid such problems in the future, Congress decided to repeal this provision as part of the Higher Education Reconciliation Act of 2005.
Students can only consolidate their education loans during the grace period or after the loans enter repayment. (Loans that are in default but with satisfactory repayment arrangements may also be consolidated.) Students can no longer consolidate while they are still in school. (The early repayment status loophole and the ability of Direct Loan borrowers to consolidate during the in-school period was repealed as part of the Higher Education Reconciliation Act of 2005, effective July 1, 2006.)
Parents, however, can consolidate PLUS loans at any time.
You Can Consolidate with Any Lender
Students and parents can consolidate their loans with any lender, even if all of their loans are with a single lender. (The single holder rule was repealed on June 15, 2006, as part of the Emergency Supplemental Appropriations Act of 2006. Borrowers no longer need to exploit the single holder rule loopholes in order to consolidate with any lender.) Direct Loans can also be consolidated with any lender. This allows you to shop around for a lender that offers a lower rate or better discounts.
Most lenders require a minimum balance before they will consolidate your loans. For example, many lenders will only offer consolidation loans for borrowers with loan balances of at least $7,500. A few lenders will offer consolidation loans for balances of $5,000 or more, and the Federal Direct Consolidation Loan program has no minimum balance for consolidation loans. (Lenders may not discriminate against borrowers who seek consolidation loans on the basis of number/type of student loans, type/category of educational institution, the interest rate on the loans, or the type of repayment schedule sought by the borrower. Lenders are, however, able to discriminate on the basis of the amount of the loans being consolidated, so lenders can set a minimum balance on the loans.)
