How to use this consolidation calculator

You’ll need your loan balance, interest rate and monthly payment. You can estimate, but your result will be more accurate if you have specifics handy.
You’ll see a total of all your loan balances and payments, plus the weighted average interest rate for all loans. Use this information to compare interest rates and monthly payments.
Each option will change your interest rate, monthly payment or repayment term.

  • If you’re consolidating federal loans, you may see a lower monthly payment and longer repayment schedule.
  • If you’re refinancing student loans, a lower interest rate will save you money. The best rates go to borrowers with good or excellent credit.
  • Income-driven repayment plans are for borrowers who have a large amount of debt compared to their income. These programs may mean substantially lower payments, but a longer repayment timeline and more accrued interest, too.
Keep in mind that refinancing with a private lender can help lower your payments for both your federal and private student loans, while the other options will only affect your federal loans. The best approach for you may be a combination of two or even three of the approaches.
