With a Consolidation loan, you can extend your repayment period to up to 30 years — depending on your total education loan debt. This can lower your monthly payment, but it can also increase the total amount you pay in interest.
TG has developed some charts to help you understand how much more interest you'll pay if you extend your repayment period. These charts show, based on sample debt amounts and allowable repayment lengths, what the monthly payment will be. They also show what the total interest and total loan amount will be once the loan is paid in full. For the following repayment schedules, we used a fixed interest rate of 6.875%.

As you can see, relatively small reductions in monthly payments can have an enormous impact on the total loan debt you'll have to repay. If you consolidate, your best option — if you can afford it — is to request a shorter 10-year or 15-year repayment schedule. If you must request a longer repayment schedule to make your monthly payments more manageable, consider making an extra payment whenever possible to be applied directly to the principal balance of the Consolidation loan — it makes smart financial sense!
