What Is Student Loan Refinancing?

Through student loan refinancing, you apply for a loan with a private lender that will pay off and replace your existing student loans. Going this route could allow you to change or modify the terms of your loans, provided you find the right lender.

A common reason you may choose a refinance is to replace higher-interest student debt like Direct PLUS loans or private student loans. If you have decent credit, income, and other financial strengths, a lender could approve you for student loan refinance rates that are lower than what you’re currently paying.

Student loan refinancing can have other benefits, too. You might want to refinance to remove a co-signer from a private student loan, or transfer ownership of parent PLUS loans.

How Do You Apply For a Student Loan Refinance?

First, shop around with different lenders to find one that offers a good rate along with features you’re looking for.

You can request rate offers from lenders that offer pre-qualification or rate quotes based on soft credit checks. This will tell you if you’re likely to get approved and what rates the lender could offer you without affecting your credit.

Next, start your application to refinance student loans once you find a lender you like. You'll likely need to provide identity-verification information such as your Social Security number and pay stubs.

Then, review and sign your loan agreement. If the lender approves you, it will send you a loan agreement outlining the full terms of the refinance. Make sure you read it carefully, and, if you have questions, ask your lender.

Lastly, the lender will process the refinance. To do so, it’ll cut checks to send to each of your old lenders to pay off the student debt you refinanced. Keep making payments to those other lenders until you’re absolutely certain the refinance has gone through.

Once the previous lenders are paid off, you'll make payments to your new lender under the terms of your refinance agreement.

You don’t have to refinance all of your student debt. It might make sense to refinance only your higher-interest student loans.

Refinancing Federal Student Loans vs. Private Student Loans

Both student loan consolidation and refinancing combine multiple loans into a single loan with a single payment. That’s about where the commonalities end for student loan refinancing and consolidation.

Refinancing federal student loans with a private lender is a significant change, and borrowers should carefully weigh their options before deciding to take this step.

What Is Federal Student Loan Consolidation?

Federal student loan consolidation combines your federal student loans into a single loan account. 

A consolidated loan’s interest rate is a weighted average of your existing student loans, so it’s not an option to lower interest costs. However, federal consolidation will preserve access to federal student loan protections and repayment options like deferment, forbearance, and income-driven repayment.

What Is Private Student Loan Refinancing?

Student loan refinancing, on the other hand, is offered by private student lenders. Unlike federal student loan rates that are set by law, lenders set their own rates—which can beat what borrowers might pay on federal student debt if you have good enough credit scores.

Private Student Loan Refinance Pros and Cons

  • Combine federal and private student loans

  • Lower interest rates

  • Change monthly payments

  • Modify student debt ownership

  • Choose your new lender

What We Don't Like
  • Credit-based application and rates

  • Not every borrower will pay less

  • Limited deferment and forbearance

  • Lose federal student loan benefits

  • Fixed repayment terms

Pros Explained

The only way to consolidate your federal and private student loans together to get a simple, single payment is through refinancing. A new refinanced student loan can come with lower costs, especially if a borrower has higher-interest federal student debt.

A lower interest rate will generate less student loan interest, which means lower monthly payments. You can also choose a longer term, which will lower monthly costs, or a shorter term, which would cost more each month but get you out of debt faster. You can refinance student loans to change who’s legally responsible for them by adding a co-signer or removing a co-signer. And you can transfer parent-owned debt such as the parent PLUS loan to the student child.

Cons Explained

Refinancing may only be an option if you have decent credit or better, a steady income, and other solid financials. Your credit will also be used to set your interest rates. If you don’t have excellent credit, you might not qualify for rates that beat what you’re already paying. It’s also up to lenders’ discretion to offer borrower protections like deferment or forbearance that can help you avoid default.

However, private student loans lack the income-driven repayment plans that federal student loans offer. Also, unlike federal student loans, private loans don't offer loan forgiveness. And, finally, many federal student loans offer three years of forbearance and three years of deferment, whereas most private lenders provide 12 months of forbearance. Shorter payment relief options mean you have less leeway if you incur a long-term income or job loss.

How Does Student Loan Consolidation Work?

Consolidating federal student loans is a pretty straightforward process. The Federal Student Aid website says you should do the consolidation in a single sitting of about 30 minutes. Here’s how it works for student loans in good standing:

  1. Start the federal direct consolidation loan application, and enter your borrower information.
  2. Select the loans you do and don’t want to consolidate, and select your desired repayment plan.
  3. Sign a promissory note for your new direct consolidation loan, agreeing to repay it.
  4. Your student loan servicer will process this application and complete the student loan consolidation. You’ll start repaying the new consolidated loan within 60 days of when it is disbursed.

Your new student loan will have the same balance as your previous loans, as well as a new rate that’s set as a weighted average of your existing rates.

Consolidating loans can also be a way to convert student loans that are ineligible for certain federal benefits into a new direct consolidation loan that might be eligible. Make sure you understand the eligibility requirements for the federal student loan program you’re interested in to be sure consolidation is right for you.

How Should I Choose a Student Loan Refinance Lender?

Refinancing student loans can be a big step. You want to be sure it will actually help you achieve your financial goals rather than set you back. The best way to ensure your student loan refinance has a positive impact is to choose the best student loan provider.

First, you should consider the costs of refinancing student loans. Collect rate quotes from at least a few private lenders, and compare these to each other as well as your current rates. This will help you figure out whether you could save money by refinancing your loans.

Next, survey lenders to figure out which ones offer what you need. If you’re refinancing to accomplish a specific purpose, such as taking over repayment of parent PLUS loans, you’ll need to know which lenders allow it. Or, if you’re planning to add a co-signer to get a lower rate, find out if the lender offers co-signer releases. Lenders that offer forbearance or deferment are also preferable, too, because they can suspend your payments while you’re facing a job loss or financial hardship.
