Student Loan Refinance Calculator — Compare Rates and Save

Compare your current student loan against a refinanced option. See monthly savings, total interest saved, and how long it takes to break even on refinancing fees — all with a clear recommendation based on your numbers.

Federal Loan Warning

Refinancing federal student loans to private loans permanently eliminates access to income-driven repayment (IDR), Public Service Loan Forgiveness (PSLF), and federal forbearance. This tool measures financial costs only. If you work in public service or rely on IDR, do not refinance.

Who Should Use This Calculator?

•Borrowers with private student loans looking for lower interest rates
•Federal loan holders considering refinancing (with awareness of trade-offs)
•Graduates with strong credit scores who may qualify for significant rate reductions
•Anyone wanting to compare the total cost of their current loan vs. a refinanced alternative
•Financial advisors helping clients evaluate student loan refinancing options

How This Calculator Works

Enter your current student loan balance, interest rate, remaining term, and the refinanced rate you have been offered. The calculator computes your monthly payment under both scenarios using standard amortization formulas, then shows you the exact monthly savings, total interest saved over the life of the loan, and how long it takes to break even on any refinancing fees.

The tool also provides a clear recommendation based on your numbers — factoring in the magnitude of savings relative to the risks and costs of refinancing. For federal loan holders, a prominent warning reminds you of the protections you would permanently lose by refinancing to a private lender.

Understanding Student Loan Refinancing

Student loan refinancing replaces your existing loan(s) with a new private loan at (ideally) a lower interest rate. This can save thousands of dollars over the life of your loan and reduce your monthly payment. However, refinancing is not right for everyone — especially federal loan borrowers who benefit from income-driven repayment plans, Public Service Loan Forgiveness, or federal forbearance.

Student loan debt affects over 43 million Americans, with an average balance exceeding $37,000. For borrowers with private loans or high interest rates (above 5-6%), refinancing can be a straightforward way to save money. For federal loan holders, the decision requires careful weighing of financial savings against the loss of federal protections. Our calculator helps you see both sides clearly.

Key Student Loan Terms

Term	Definition
Refinancing	Replacing existing loan(s) with a new loan, ideally at a lower interest rate. Creates a brand new loan agreement with a private lender.
IDR Plans	Income-Driven Repayment plans cap federal loan payments at 10-20% of discretionary income, with forgiveness after 20-25 years.
PSLF	Public Service Loan Forgiveness — forgives remaining federal loan balance tax-free after 120 qualifying payments while working for government or nonprofits.
Forbearance	Temporary pause on loan payments during financial hardship. Available for federal loans; rarely offered by private lenders.
Break-Even Point	The number of months until your cumulative monthly savings from refinancing exceed any upfront refinancing fees paid.
Origination Fee	A one-time fee charged by some lenders to process a refinance. Typically 0-2% of the loan amount. Factor this into your break-even calculation.

Expert Tips for Student Loan Refinancing

1
Never refinance if you qualify for PSLF: If you work for a government or nonprofit employer, Public Service Loan Forgiveness forgives your remaining balance after 120 payments. Refinancing makes you permanently ineligible — this could cost you tens of thousands in forgiveness.
2
Refinance private loans first: Private student loans lack federal protections anyway, making them ideal candidates for refinancing. If you can drop the rate by even 1%, the savings add up significantly over 10+ years.
3
Compare at least 3-5 lenders: Rates and terms vary significantly between lenders. Most offer rate checks with a soft credit pull that does not affect your credit score. Comparing multiple offers takes 30 minutes and can save thousands.
4
Consider shortening your term: If your budget allows, refinancing into a shorter term (e.g., 5 years instead of 10) dramatically reduces total interest paid. Even if the monthly payment is higher, the interest savings are often substantial.
5
Build an emergency fund first: Before committing to private refinanced payments, ensure you have 3-6 months of expenses saved. Private lenders offer limited forbearance compared to federal programs — if your income drops, you still owe the full payment.

Student Loan Refinance FAQ

When should you refinance student loans?+

Refinancing makes sense when you can qualify for a meaningfully lower interest rate (typically 1%+ reduction), you have stable income and good credit (670+), and you don't need federal loan protections like income-driven repayment or Public Service Loan Forgiveness (PSLF).

What are the risks of refinancing federal student loans?+

Refinancing federal loans to private loans permanently removes access to income-driven repayment plans (IDR), Public Service Loan Forgiveness (PSLF), federal forbearance and deferment options, and potential future federal loan forgiveness programs.

What credit score do I need to refinance?+

Most private lenders require a minimum credit score of 650-680, but the best rates typically go to borrowers with 720+ scores. You can often add a creditworthy co-signer to access better rates.

What is a break-even point for refinancing?+

The break-even point is how long it takes for your monthly savings from refinancing to cover the upfront refinancing fee. If your fee is $350 and you save $50/month, break-even is 7 months. Only refinance if you plan to keep the loan past break-even.

Can I refinance just some of my student loans?+

Yes. Many borrowers refinance only their private loans while keeping federal loans intact to preserve federal protections. This is often the safest approach if you have a mix of federal and private loans.

What is income-driven repayment and why does it matter?+

Income-driven repayment (IDR) plans cap your monthly federal loan payment at 10-20% of your discretionary income and forgive any remaining balance after 20-25 years. This is a critical safety net if your income drops. Refinancing to a private lender eliminates access to IDR permanently.

Should I refinance if I work in public service?+

No. If you work for a government or nonprofit employer, you may qualify for Public Service Loan Forgiveness (PSLF) after 120 qualifying payments. PSLF forgives your entire remaining federal loan balance tax-free. Refinancing to a private lender makes you permanently ineligible.

Fixed rate vs variable rate: which should I choose when refinancing?+

Fixed rates offer payment predictability and protection against rate increases. Variable rates start lower but can rise over time. If you plan to pay off the loan within 5 years, a variable rate may save money. For longer terms, fixed rates are safer.

How much can I save by refinancing student loans?+

Savings depend on your rate reduction and remaining balance. A borrower with $50,000 in loans dropping from 6.8% to 4.5% on a 10-year term saves approximately $6,500 in total interest and $55/month. Use our calculator to see your exact numbers.

Can I refinance student loans more than once?+

Yes. There is no limit on how many times you can refinance. If rates drop further or your credit score improves significantly, refinancing again can save additional money. Just watch for any origination fees that could offset the savings.
