⚠️ Federal Student Loan Advisory Notice
If you are refinancing Federal Student Loans into a private loan, you will permanently lose federal protections including Income-Driven Repayment (IDR/SAVE) plans, Public Service Loan Forgiveness (PSLF), and mandatory administrative forbearance options.
When Does Student Loan Refinancing Make Sense?
Student loan refinancing involves taking out a new private loan with lower interest rates or a modified repayment schedule to pay off your existing federal or private student debts.
Key Refinancing Objectives
- Lower Your Interest Rate: If your credit score or income has improved since college, private lenders may offer interest rates significantly below original federal rates.
- Reduce Monthly Outflow: Extending your loan term lowers your mandatory monthly payment, freeing up monthly cash flow.
- Accelerate Debt Freedom: Shortening your loan term (e.g. from 10 years to 5 years) reduces overall lifetime interest.

What is the US Student Loan Refinancing Estimator?
The US Student Loan Refinancing Estimator is a financial planning tool designed to help borrowers evaluate the monthly and lifetime savings of refinancing their federal or private student loans.
Refinancing involves taking out a new loan with a private lender to pay off your existing student loans, ideally securing a lower interest rate or a more favorable repayment term:
• Interest Rate Savings: A lower interest rate means less interest accrues on your principal balance each month. For large student loan balances (e.g., $35,000 or more), even a 1.0% to 2.0% rate reduction can save thousands of dollars over a 10-year term.
• Term Adjustments: You can choose to shorten your term (e.g., from 15 to 10 years) to pay off debt faster and minimize interest, or extend the term to reduce your monthly payment amount, though this increases total interest paid over time.
• Federal vs. Private Refinancing Warning: Refinancing private student loans is generally a low-risk way to save money. However, refinancing federal student loans into a private loan permanently removes access to federal benefits. This includes Public Service Loan Forgiveness (PSLF), income-driven repayment plans (like SAVE), and administrative deferment or forbearance options.
This calculator compares your current loan's remaining term, balance, and rate side-by-side with a proposed refinanced loan to display your monthly cash flow change and net lifetime interest savings.

Formula & Calculation Method
Monthly payment = P × [r(1+r)^n] / [(1+r)^n - 1]. Total interest = total paid minus principal. Interest savings = current total interest minus new total interest.
Example Calculation
Refinancing a $35,000 loan from 6.5% rate down to 4.5% over a 10-year term saves $4,129 in lifetime interest and reduces the payment by $34/month.
