Student Loan Refinance Calculator

Refinancing makes sense when you can secure a lower interest rate than your current loan, which reduces monthly payments and total interest paid over time. However, if you have federal student loans, refinancing with a private lender means losing access to federal protections like income-driven repayment plans and loan forgiveness programs. Private student loan borrowers typically have the most to gain from refinancing.

Your savings depend on the difference between your current and new interest rates, your remaining balance, and the new loan term. Even a 1–2% rate reduction on a $35,000 balance can save thousands of dollars in total interest. Use this calculator to see your exact monthly and lifetime savings based on your specific numbers.

Lenders typically look at your credit score (usually 650+ for approval, 700+ for the best rates), debt-to-income ratio, employment status, and income stability. A co-signer with strong credit can help you qualify if your own profile needs improvement. Most lenders allow you to check your rate with a soft credit pull, which won't affect your credit score.

As of 2024–2025, competitive refinance rates generally range from around 4% to 8% depending on your creditworthiness, loan term, and whether you choose a fixed or variable rate. The best rates go to borrowers with excellent credit (720+), stable income, and low debt-to-income ratios. A fixed rate provides payment certainty, while a variable rate may start lower but can rise over time.

It depends on the loan term you choose. If you select a longer term than what you have remaining, your monthly payments will be lower but you'll pay more interest overall. Choosing a shorter or equal term keeps total interest lower. This calculator lets you compare different term options so you can find the right balance between monthly cash flow and total cost.

Before refinancing, make sure you have stable employment, an emergency fund, and are not expecting to need federal loan protections like deferment or forbearance. If your income varies significantly or you anticipate financial hardship, keeping federal loan options available may be more important than securing a lower rate through private refinancing.

Yes, most private lenders allow you to consolidate both federal and private student loans into a single refinanced loan. However, doing so converts your federal loans to private loans, permanently eliminating access to federal benefits like Public Service Loan Forgiveness (PSLF), income-driven repayment, and federal deferment options. Carefully weigh this trade-off before consolidating federal loans.

There is no legal limit to how many times you can refinance student loans. If your credit score improves significantly or market interest rates drop, refinancing again could yield additional savings. Just be aware that each application may trigger a hard credit inquiry, and you should weigh any fees or costs against the potential savings from a lower rate.
