Student Loan Refinance Calculator

Student Loan Refinance Calculator

by | Jun 23, 2025 | Student Loan Refinancing

If you're stuck with high interest rates or managing multiple payments each month, refinancing your student loan could be a smart move. This student loan refinancing calculator helps you quickly determine how your current loan setup compares to current refinancing options.

Input a few basic information points, including your APR, credit score, monthly payment, and student loan balance. After which, you'll discover your personalized Student Loan Score and explore whether refinancing makes the best financial sense.

Highlights

  • Identify whether you're overpaying in student loan interest

  • See how your current student loan payment compares to current going rates

  • Estimate your savings from student loan consolidation

  • See and use personalized data to potentially save money over the life of your loan

What’s a Good Student Loan APR?

While federal student loan APRs are currently fixed, private student loan rates vary widely depending on the lender and your credit score details. If your current rate is above 6% or 7%, and your credit score has improved since you graduated or left school, student loan refinance options may allow you to qualify for a lower fixed interest rate or avoid potentially rising variable rates.

Using this calculator, you’ll see if you may be paying more than necessary, and if you could receive a better offer from one of the top student loan refinancing providers available.

How to Calculate If Student Loan Refinancing Is Worth It

Refinancing your student loan is about more than just securing a lower rate. It’s also about improving your financial picture. Here’s a simple formula to estimate your potential savings:

(Old Monthly Payment × Loan Term) – (New Monthly Payment × Loan Term) = Estimated Interest Saved

While this is a very simplified example, the equation helps estimate your potential savings. The loan refinance calculator below does this for you instantly using the information you provide.

Use it to evaluate how much you could save money by locking in a lower rate or switching from variable interest rates to a fixed rate.

Who Should Consider Student Loan Refinancing?

You might benefit from student loan refinance options if:

  • Your current student loan payments include high interest rates

  • You’ve improved your credit score since taking out your loans

  • You’re ready to consolidate multiple loans into one simple payment

  • You want to shorten the life of your loan or lower your monthly payment

If you’re thinking about refinancing federal student loans, be aware that doing so may remove your access to federal benefits like income-driven repayment plans or future student loan forgiveness.

Tips Before Using the Student Loan Refinance Calculator

To get the most accurate results from the student loan refinancing calculator, have these items ready:

  • Your current APR or interest rate or rates

  • Your student loan balance or balances

  • Estimated monthly payment amounts

  • Your credit score

Your results can help you determine how favorable your current loan is, and whether refinancing your student loan might help you save money or simplify your financial life.

Who to Talk to About Refinancing

If your results suggest that you could benefit by refinancing your student loans, the next step is to compare real offers. Credible Student Loan Refinancing is a trusted platform that lets you compare prequalified rates from multiple lenders in minutes, without impacting your credit score.

Frequently Asked Questions

Can I refinance federal and private student loans together?

Many private lenders allow you to consolidate both federal and private student loans into a single refinanced loan. Doing so can reduce your monthly payment, streamline your repayment process, and often save money over the life of your loan. However, once you refinance federal student loans, you’ll lose access to benefits like income-driven repayment plans and any future student loan forgiveness programs. Be sure to evaluate what matters most for your situation.

Will refinancing hurt my credit score?

Using a student loan refinance calculator or checking your prequalified rates through platforms like Credible won’t hurt your score, as the format uses soft credit pulls. However, submitting a full loan application will result in a hard inquiry, which may temporarily lower your credit score. Over time, successful refinancing could improve your score by reducing your debt-to-income ratio and making your student loan payment more manageable.
