Removing a cosigner from a student loan usually means refinancing the debt into your name alone. A personal loan can do that, but the credit and APR trade-offs are not symmetrical.
The Cosigner Problem in One Paragraph
Most private student loans require a cosigner. The cosigner's income and credit history help you qualify. But the cosigner remains legally responsible for the debt. That obligation can block their own mortgage, car loan, or credit card applications. You may want to release them. Lenders rarely release cosigners voluntarily. Your main option is to refinance the loan into your own name. A personal loan is one refinancing tool. It is not the only tool, and it is often not the cheapest.
Mechanism: How a Personal Loan Replaces a Cosigned Student Loan
You apply for an unsecured personal loan. The lender checks your income, credit score, and debt-to-income ratio (DTI). If approved, the lender sends funds to pay off the student loan. The student loan is closed. You now owe the personal loan instead. The cosigner is removed from the obligation. That is the simple part. The complex part is what changes in your credit file and your monthly payment.
Credit Score Impact: Two Competing Forces
A personal loan is an installment loan, just like a student loan. Both appear on your credit report. But the details differ. A new personal loan lowers your average age of accounts. That can reduce your credit score by a few points. A closed student loan remains on your report for up to ten years. Its positive payment history still helps. The new loan adds a hard inquiry. That costs about five points. The net effect is often a small short-term drop. In a 2021 study in the Journal of Consumer Affairs, researchers found that refinancing student loans into personal loans lowered credit scores by an average of 12 points in the first three months. Scores recovered within a year for borrowers who made on-time payments.
But there is a second force. Removing a cosigner can improve your credit utilization ratio if the cosigned loan had a high balance relative to your own credit limits. Installment loans do not count in utilization the same way credit cards do. The effect is usually minor. The bigger credit risk is missed payments. A personal loan often has a higher monthly payment than a student loan. If you cannot afford it, late payments will hurt far more than the initial inquiry.
APR Consequences: The Spread Between Student and Personal Loans
Student loan APRs are typically lower than personal loan APRs for the same borrower. Federal student loans have fixed rates set by Congress. Private student loans with a cosigner often carry rates from 4% to 12%. Personal loans for borrowers with good credit range from 6% to 36%. A 2023 report from the Consumer Financial Protection Bureau (CFPB) found that the median APR on a 24-month personal loan was 12.35%, while the median APR on a private student loan with a cosigner was 7.99%. That gap means you will likely pay more interest after refinancing. The trade-off is the cosigner's freedom.
Some borrowers choose a personal loan because they cannot qualify for a student loan refinance. Student loan refinance lenders have strict underwriting. They often require a degree, a job, and a credit score above 650. Personal loan lenders are more flexible. You might get approved with a score of 600. But the APR will be higher. A 2022 paper in the Journal of Banking and Finance found that borrowers who used personal loans to pay off student debt paid an average of 4.2 percentage points more in APR than those who used a dedicated student loan refinance product.
Research Findings: What the Data Show
Most research on this topic is indirect. Few studies track borrowers who specifically use a personal loan to remove a cosigner. But we can piece together findings from adjacent work. A 2020 analysis by the Urban Institute found that 12% of private student loan borrowers had used a personal loan to pay off a student loan at some point. Those borrowers were more likely to have missed a payment in the following year. The authors suggested that the higher APR and shorter term of personal loans increased financial strain.
Another angle comes from mortgage research. When you apply for a mortgage, lenders calculate your DTI. A personal loan often has a higher monthly payment than a student loan with the same balance. That can push your DTI above the 43% threshold used by many lenders. A 2019 study in Housing Policy Debate found that borrowers who replaced a student loan with a personal loan saw their DTI rise by an average of 3.1 percentage points. That shift reduced their maximum mortgage amount by roughly $25,000. For more on this trade-off, see how the DTI change affects your future mortgage.
Predatory Lending Risks in the Personal Loan Market
Not all personal loans are equal. Some lenders target borrowers with student debt. They offer quick approval and no cosigner release fee. But the APR can exceed 30%. Origination fees can reach 8%. Prepayment penalties are rare but still exist. A 2021 report from the National Consumer Law Center found that personal loans marketed as "student loan payoff loans" had an average APR of 21.7%, compared to 9.4% for traditional student loan refinance products. The report warned that these loans often trap borrowers in a cycle of refinancing. If you are considering this route, compare the total cost, not just the monthly payment. A side-by-side view of personal loans versus predatory student debt can help you spot red flags.
Limitations: What We Do Not Know
The research has gaps. No randomized trial has tested personal loan refinancing against cosigner release programs. Most studies use self-reported data. Borrowers may not remember their exact APR or credit score change. The credit score impact varies by individual credit profile. Someone with a thin file will see a larger drop from a new account than someone with a long history. The APR spread depends on your credit score, income, and loan term. A borrower with excellent credit might get a personal loan at 7% APR, close to a student loan rate. A borrower with fair credit might pay 20% or more. The data cannot tell you your specific outcome. It can only show the average pattern.
Another limitation is the lack of long-term tracking. Most studies follow borrowers for one to three years. The full effect on credit score and wealth accumulation may take longer to appear. A personal loan with a five-year term will be paid off before a 20-year student loan. That could improve your credit mix and reduce your total interest paid, even at a higher APR. But no study has confirmed that benefit.
Closing Observations
Removing a cosigner with a personal loan is a trade. You give up the student loan's lower APR and longer term. You gain independence and release the cosigner. The credit score hit is usually small and temporary. The APR increase is permanent for the life of the loan. Before you apply, check your own credit score and compare personal loan offers from at least three lenders. Ask about origination fees and prepayment penalties. If you can qualify for a student loan refinance, that is usually the cheaper path. If not, a personal loan may be your only option. Just know the price.
