📌 What Is a Student Loan Interest Rate?
A student loan interest rate is the percentage charged on the total amount you borrow to attend school. This rate determines how much extra you’ll pay over the life of your loan, making it one of the most important factors when choosing how to finance your education.
There are two main types:
- Fixed interest rate – Stays the same for the life of the loan.
- Variable interest rate – Can fluctuate over time depending on market conditions.

💸 What Affects Your Student Loan Interest Rate?
Several factors determine your interest rate:
- Loan type (federal vs. private)
- Credit score (for private loans)
- Cosigner strength
- Loan term (shorter terms usually = lower rate)
- Repayment plan
For federal loans, your rate is set by Congress. For private loans, lenders evaluate your creditworthiness.
