Private student loans are credit-based education loans issued by banks, credit unions, and online lenders to cover college costs after federal aid is exhausted. Because they lack the consumer protections built into federal student loans, the U.S. Consumer Financial Protection Bureau and StudentAid.gov both recommend that borrowers max out federal aid first and use private loans only to fill a remaining gap. As of May 2026, private student loan rates generally run about 5%-15% variable and 6%-15% fixed, with the actual rate driven largely by the borrower’s credit profile and whether a creditworthy cosigner is added.
Key Takeaways
- Always max out federal aid first. Submit the FAFSA and accept federal options in this order: subsidized loans, unsubsidized loans, then Direct PLUS loans if needed. Federal loans carry protections private loans simply do not offer.
- Private rates are credit-driven. Where federal rates are set by Congress and identical for every borrower, private rates depend heavily on your credit history, income, and cosigner. A strong cosigner can lower a rate by roughly 2-4 percentage points.
- No federal safety net. Private loans typically have no income-driven repayment, limited deferment and forbearance, and no broad forgiveness programs (no PSLF equivalent, no IDR forgiveness).
- Cosigner release is possible but not automatic. Many lenders allow a cosigner to be released after 24-48 consecutive on-time payments, provided the primary borrower then qualifies independently on credit and income.
- Fixed vs variable matters. Fixed rates stay the same for the life of the loan; variable rates are tied to a benchmark such as 30-day Average SOFR plus a margin and can rise or fall with the market.
Federal vs private student loans
The single most important decision in student-loan borrowing is the order: federal first, private only to fill what’s left. Federal Direct Loans, available through StudentAid.gov after filing the FAFSA, come with a uniform fixed rate set annually by Congress and a meaningful package of borrower protections.
Federal student loans include:
- Income-driven repayment plans that cap monthly payments at a share of discretionary income.
- Deferment and forbearance rights for unemployment, economic hardship, military service, and in-school enrollment.
- Forgiveness programs such as Public Service Loan Forgiveness (PSLF) for qualifying public-sector workers and forgiveness of remaining balances after the IDR plan term.
- Death and disability discharge available to every federal borrower.
Private student loans, by contrast, are underwritten on credit. Approval and pricing reflect the borrower’s (and cosigner’s) credit score, income, and debt-to-income ratio. There are typically no aggregate federal caps, funding can be faster, and graduate borrowers in fields such as medicine or law can sometimes borrow more than federal limits allow. But private loans generally offer no income-driven repayment, only narrow hardship forbearance, and no broad forgiveness pathway.
The recommendation from CFPB and StudentAid.gov is consistent: exhaust federal eligibility first, then consider private loans only for the remaining gap.
Types of private student loans
- Undergraduate loans – the most common product; typically require a cosigner for traditional-age students.
- Graduate loans – often higher borrowing caps; some specialty products for medical, law, MBA, dental, and health-professions students with deferment through residency or articling.
- Career training and certificate loans – for vocational and non-degree programs that may not qualify for federal aid.
- Bar exam loans – short-term loans for law graduates covering bar prep and living expenses during the study period; typically short repayment terms and higher rates.
- Residency and relocation loans – help newly minted physicians and dentists bridge the gap between graduation and full attending income; also typically short term and higher rate.
How to compare private student lenders
When evaluating private student loan offers, work through this checklist in order:
- APR (fixed and variable). Compare the full annual percentage rate, not just the headline interest rate. Look at both the low and high ends of each lender’s range.
- Origination and disbursement fees. Most major private student lenders now charge $0 origination, but confirm in writing.
- In-school repayment options. Three common choices: deferred (no payments until after school, interest capitalizes), interest-only while enrolled, or immediate full principal-and-interest payments. The earlier you start paying, the less you pay overall.
- Cosigner release policy. How many consecutive on-time payments are required? What credit standard must the borrower meet at release? Some lenders do not offer release at all.
- Multiyear approval. Some lenders prequalify you for future academic years, which helps with planning and avoids re-underwriting each year.
- In-school and post-school grace period. Standard is six months after leaving school, but it varies.
- Hardship forbearance. How many months of forbearance are available over the life of the loan? What qualifies?
- Refinance flexibility. You can almost always refinance private loans later; confirm there are no prepayment penalties.

Why a cosigner matters
Most traditional-age undergraduates have a thin or nonexistent credit file and limited income, so they cannot qualify for a competitive private loan on their own. Adding a creditworthy cosigner – typically a parent, guardian, or other relative – can be the difference between denial and approval, and can lower the rate by roughly 2-4 percentage points.
A cosigner is legally responsible for the loan. If the primary borrower misses payments, the lender can pursue the cosigner, and missed payments hit both credit reports. The cosigner’s debt-to-income ratio also reflects the full loan balance until release.
Most major lenders offer a cosigner release after a set number of consecutive on-time payments (commonly 24, 36, or 48 months) provided the primary borrower can re-qualify independently based on credit, income, and employment. Release is not automatic – the borrower has to apply and meet the lender’s underwriting standard.

Frequently asked questions
Should I get a private student loan or use federal aid first?
Federal first, in nearly every case. Federal Direct Loans come with income-driven repayment plans, broad deferment and forbearance rights, and forgiveness pathways such as PSLF that private loans do not offer. Submit the FAFSA, accept subsidized then unsubsidized loans, consider Direct PLUS if needed, and use a private loan only to fill what remains. The CFPB and StudentAid.gov give the same guidance.
Do I need a cosigner for a private student loan?
Most traditional-age undergraduates do. Lenders underwrite on credit and income, and most undergrads don’t yet have either. A creditworthy cosigner can be the difference between approval and denial, and typically lowers the rate by roughly 2-4 percentage points. Graduate students and working adults with established credit may qualify alone.
Can my cosigner be released later?
At many lenders, yes. Cosigner release usually requires 24-48 consecutive on-time, full payments and a successful re-underwriting of the primary borrower based on credit, income, and employment. Release is not automatic and not offered by every lender, so confirm the policy in writing before you sign.
What’s the difference between fixed and variable rate?
A fixed rate is locked in at origination and stays the same for the life of the loan, so your payment is predictable. A variable rate is tied to a benchmark – most commonly 30-day Average SOFR – plus a margin set by the lender, and it can rise or fall with the market. Variable rates often start lower but carry interest-rate risk over a 10-15 year term.
Can private student loans be forgiven?
Forgiveness on private student loans is rare. There is no private equivalent to Public Service Loan Forgiveness or income-driven repayment forgiveness. Most lenders only discharge balances in cases of total and permanent disability or the borrower’s death, and even those policies vary by lender. If forgiveness eligibility matters to you, that is a strong argument for using federal loans wherever possible.
When does interest start accruing on a private student loan?
Typically at disbursement – interest begins building the moment funds are sent to the school. Most lenders offer three in-school payment options: deferred (no payments until after school, with interest capitalizing onto the balance), interest-only payments while enrolled, or immediate full principal-and-interest payments. The earlier you start paying interest, the less you owe overall.
Can I refinance private student loans?
Yes. Once you have steady income, established credit, and a track record of on-time payments, you can refinance private student loans into a new loan – potentially at a lower rate or different term. See our student loan refinancing hub for current options and considerations.
What’s the 2026 private student loan rate range?
As of May 2026, private student loan rates generally run approximately 5%-15% for variable-rate loans and 6%-15% for fixed-rate loans. Where you land in that range depends heavily on your credit profile, income, school and program, and whether you add a creditworthy cosigner. Always compare APRs – not just headline rates – across at least three lenders before signing.
