Your student loan repayment term

Your loan repayment term is the number of years you have to pay it back. Federal loans generally have a standard repayment schedule of 10 years. For private student loans, the repayment term can range anywhere from 5–20 years, depending on the loan. You’ll be given a definite term for your loan when you apply.

Interest rates for federal and private student loans

The average interest rate will be different for federal student loans and private student loans. Federal student loans have a single, fixed interest rate, which means that your loan’s rate doesn’t change over time.

You may have noticed that there’s a range of interest rates associated with a private student loan. Private student loans are credit-based. That means the rate you’ll be offered depends on your creditworthiness—and that of your cosigner, if you have one—together with several other factors. When you apply for a loan, you’ll be given an interest rate, either fixed or variable, depending on which is offered and which type of rate you’ve chosen.

Sallie Mae does not guarantee the estimator accuracy or applicability to a person's individual circumstances. The estimated monthly payment assumes the same payment amount and fixed interest rate for the life of the loan and does not account for a variable interest rate. The estimate does not account for missed payments, the use of deferment or forbearance, or any required minimum monthly payment amount for a particular loan. For new loans, this estimate does not account for any payments made during the in-school and separation or grace periods, or any interest that accrues or capitalizes during that time. For Sallie Mae loans entering principal and interest repayment, this estimate does not factor in accruing interest or any payments made between now and when the loan enters principal and interest repayment.
