Student Loan Interest Rate Formula:
| From: | To: |
The current federal student loan interest rates for the 2024-2025 academic year are 5.50% for undergraduate Direct Loans, 7.05% for graduate Direct Loans, and 8.05% for PLUS loans. Private loan rates vary by lender and borrower creditworthiness.
Student loan interest accrues daily using the formula:
Where:
Explanation: Interest accumulates daily based on your current principal balance. For federal loans, unpaid interest may capitalize (be added to principal) at certain times.
Details: Knowing how interest accrues helps borrowers make informed decisions about repayment strategies, extra payments, and loan consolidation options.
Tips: Enter your current loan balance, the annual interest rate (e.g., 5.50 for 5.5%), and the number of days you want to calculate interest for. The calculator will show how much interest would accrue during that period.
Q1: Are federal student loan rates fixed or variable?
A: All federal student loans have fixed interest rates that don't change over the life of the loan.
Q2: When does interest start accruing?
A: For unsubsidized federal loans and private loans, interest starts accruing immediately. For subsidized federal loans, the government pays interest while you're in school.
Q3: How often is interest compounded?
A: Federal student loans use simple daily interest (not compounded daily), though unpaid interest may capitalize (be added to principal) at certain times.
Q4: Can I lower my interest rate?
A: Federal loan rates are set by Congress, but you may qualify for rate reductions through auto-debit (typically 0.25% reduction). Private lenders may offer lower rates for refinancing.
Q5: Where can I find my exact interest rate?
A: Check your loan servicer's website or your original loan documents. Federal loan rates are set based on the academic year the loan was disbursed.
