Student Loan Interest Rates

Student loan interest rates can be difficult to understand. It helps to have a few key terms explained first.

Your interest rate will be either fixed or variable. Your actual interest rate will depend on:

A fixed interest rate means that it will remain the same over the life of your loan.

A variable interest rate typically means that it will fluctuate over the life of your loan based on the change to an index that reflects changes in the market rates of interest. Variable rate loans typically change rates every July 1.

Private, Institutional, and State Loans

While federal student loans have standard interest rates set by the federal government, private, institutional, and state loan terms can vary greatly.

  • Private loans are provided by private banks or credit unions, and they generally have variable interest rates set by the lender. Contact your lender to learn more.
  • Institutional loans are provided by your school, and they can have variable or fixed interest rates set by the school. Contact your school to learn more.
  • State loans are loans provided through state-funded programs, and their interest rates vary depending on the state you are in. Contact your servicer or state's office of education to learn more.

Weighted Averages

Consolidation loan interest rates are calculated by using the process below.

As an example, if you were in repayment on a loan of $5,000 at 6.8% and a loan of $10,000 at 6.0%, your rate would be 6.375%. Here is why:

  • The amount you owe on each loan is multiplied by its respective interest rate (5,000 x 0.068 = 340; 10,000 x 0.06 = 600).
  • These amounts are then added together (340 + 600 = 940).
  • This total is divided by the total amount you owe (940 / 15,000 = 0.063).
  • Multiplied by 100, this number creates your weighted average interest rate (100 x 0.063 = 6.3).
  • Your weighted average is then rounded up to the nearest 1/8% percent (6.3 + 0.075 = 6.375).

Keep in mind that rates are capped at 8.25%.
