How to Get a Private Student Loan in 2026: Requirements, Application Steps, and Approval Tips
Here's a number that reframes the whole decision: at Citizens, 98% of undergraduate private student loans are issued with a cosigner. That figure applies specifically to Citizens' undergraduate loans rather than the entire private student loan market, but it illustrates how common cosigners are among traditional undergraduate borrowers.
The "solo" private student loan many 18-year-olds imagine applying for can therefore be difficult to obtain. Private lenders underwrite applications based on creditworthiness, income, existing obligations, and other factors that many traditional students have not yet had time to establish.
Why this matters more in 2026 than it did last year
The private student loan market became more important in 2026 because of major changes to federal graduate borrowing. Under the One Big Beautiful Bill Act, Grad PLUS Loans are generally no longer available for graduate and professional students for loans first disbursed on or after July 1, 2026.
A limited transition exception applies to certain students who were already enrolled in the same program and had received a Direct Loan for that program before July 1, 2026. The National Association of Student Financial Aid Administrators tracks how the One Big Beautiful Bill Act is being implemented , including the transition provisions.
New federal borrowing limits also took effect. Graduate students are generally limited to $20,500 per year and $100,000 in aggregate, while eligible professional students may borrow up to $50,000 per year and $200,000 in aggregate. A separate $257,500 lifetime maximum generally applies across federal student loans borrowed by the student.
Grad PLUS previously allowed eligible graduate and professional students to borrow up to the school-certified cost of attendance, minus other financial aid. With that option generally unavailable to new borrowers, some students may need to consider private loans to cover a remaining funding gap. Unlike most federal undergraduate loans, private loans are approved and priced according to the borrower's or cosigner's creditworthiness, income, and other underwriting criteria.
Rates depend on the lender, repayment term, applicant's credit profile, cosigner strength, and whether the rate is fixed or variable. The lowest advertised rates are generally available only to applicants with excellent credit, sufficient income, and any required discounts, such as automatic payments.
What this means for you: Do not treat the advertised "as low as" APR as the rate you are likely to receive. Compare current offers from several lenders and review the APR, repayment term, fees, discounts, and whether the rate is fixed or variable.
Step 1: File the FAFSA and max out federal loans first
This isn't a formality — it's a money decision. Federal Direct loans don't require a credit check or income for most undergraduates, carry fixed rates set by Congress, and come with protections private loans rarely match: income-driven repayment, deferment, forbearance, and statutory rehabilitation after default. The Consumer Financial Protection Bureau lays out how federal and private student loans compare in detail.
The practical rule is to use private loans as a gap-filler after grants, scholarships, work-study, and available federal loans — not as the first borrowing option.
Federal and private loans also follow different delinquency and default rules. The Consumer Financial Protection Bureau notes that most federal student loans go into default after more than 270 days of missed payments. Private-loan default timelines depend on the lender and the promissory note and may be considerably shorter — often after roughly 90 days, though some notes specify even sooner. For a fuller comparison, see our guide to the federal vs. private late-payment penalty gap.
Step 2: Understand what lenders actually check
Private student loan underwriting comes down to four inputs. Miss the mark on one, and a cosigner usually becomes the fix rather than a nice-to-have.
Credit score
There is no universal minimum credit score across private student lenders. Many lenders prefer applicants or cosigners with credit scores in at least the mid-600s, while the strongest rates are generally reserved for borrowers with very good or excellent credit, sufficient income, and a strong overall financial profile. Citizens provides additional information about qualifying for private student loans with limited or weaker credit .
Income and employment
Lenders want evidence that the borrower or cosigner has enough reliable income to manage the new loan payment alongside existing obligations. Some lenders may accept different forms of documented income, but requirements vary significantly by company and loan product. Stable income can improve both approval odds and the terms offered.
Debt-to-income ratio (DTI)
DTI compares your required monthly debt payments with your gross monthly income. Private student lenders use income, existing debts, and the expected new loan payment to assess whether the borrower or cosigner can reasonably afford the debt.
Exact DTI limits vary by lender and are often not disclosed publicly. A strong credit score therefore does not guarantee approval if the applicant's existing monthly obligations are already high.
Basic eligibility
Eligibility rules vary by lender and loan product. Common requirements may include enrollment at an eligible school, meeting the lender's age and credit criteria, and being a U.S. citizen or permanent resident.
Some lenders also work with international or DACA students, either with an eligible U.S. cosigner or through specialized loan products. Check the lender's current eligibility requirements before applying. For more, see this overview of education loans for international students .
Illustrative example: $25,000 loan with a 10-year repayment term. The comparison uses a 12.5% fixed rate for one example and a 6.5% fixed rate for another. These rates are used only to demonstrate how a lower APR affects the payment and total interest; they are not representative offers and are not guaranteed by adding a cosigner.
What this means for you: A creditworthy cosigner may improve approval odds and may help the borrower qualify for a lower rate. In this illustration, moving from 12.5% to 6.5% reduces the monthly payment from approximately $366 to $284 and lowers total interest by about $9,800.
Step 3: Run the numbers before you sign
The rate you're offered translates directly into dollars. The examples below use hypothetical fixed rates to show how APR affects the cost of a $25,000 loan over 10 years. They are illustrations, not current market averages or loan offers.
The spread is the story: in these illustrations, the borrower with the highest rate repays nearly $15,000 more than the borrower with the lowest rate for the same $25,000 principal.
This does not mean that adding a cosigner will produce a specific rate reduction. However, stronger credit, a qualified cosigner, a smaller loan amount, or a shorter repayment term may reduce the overall borrowing cost. You can model your own numbers with our free loan calculator .
In the current market, a fixed APR below 5% would generally be highly competitive and is usually available only to exceptionally strong applicants. However, no single rate range is appropriate for every borrower.
Compare offers based on APR, repayment term, fees, available discounts, cosigner requirements, and whether the rate is fixed or variable. An offer in the 9%–12% range may still be reasonable for some borrowers, but it makes comparison shopping especially important.
Rates near the upper end of a lender's advertised range should be reviewed carefully against available federal loans, scholarships, school payment plans, and offers from other lenders.

Fixed vs. variable rate: the trade-off
Private lenders commonly offer both fixed and variable rates. The difference between the two can change over time and varies by lender, so borrowers should compare current APRs rather than assume that one option always starts lower.
Fixed rate — pros
- Payment never changes — full predictability across a 10–15 year term
- Protects you if benchmark rates (SOFR, Prime) rise
- Easier to budget for a long repayment window
Variable rate — trade-off
- May start below or above the available fixed rate, depending on market conditions and lender pricing
- Can change monthly, quarterly, or at another interval stated in the loan agreement
- Creates more uncertainty over a long repayment term
- May cost less if the starting rate is lower and the loan is repaid quickly, but that outcome is not guaranteed
A fixed rate provides payment predictability, which may be valuable over a long repayment term. A variable rate can be worth considering when the initial APR is meaningfully lower and the borrower expects to repay the balance quickly, but future rate changes cannot be predicted.
What if your situation is different?
Approval on your own can be difficult, and any offer you do receive will likely carry a higher rate. A creditworthy cosigner is often the most effective path and may help you qualify for better terms. If no cosigner is available, confirm you've used available federal options before accepting an expensive private loan.
Many private lenders require U.S. citizenship or permanent residency, but policies vary. Some lenders allow eligible international or DACA students to apply with a qualifying U.S. citizen or permanent-resident cosigner, while a smaller number offer specialized products without a U.S. cosigner. Review each lender's citizenship, residency, school, visa, and cosigner requirements before applying. See this overview of international student loans for more.
Some lenders offer cosigner release after a required number of consecutive on-time payments, provided the borrower can then qualify independently based on credit, income, and other underwriting criteria. Not every lender offers cosigner release, and release is not automatic. Review the lender's written policy before signing and confirm the minimum payment history and qualification requirements. See this general overview of private student loans and cosigners for more.
A variable rate may cost less before refinancing if its initial APR is lower, but that result is not guaranteed. Interest rates may increase, and future refinancing depends on your credit, income, employment, and market conditions at the time you apply. Do not accept a variable rate that you could not afford if it increased, and do not rely on refinancing as a guaranteed exit strategy.
Your application, step by step
Once federal aid is locked in and you know your gap, the private process is fairly consistent across lenders:
- Check your credit report first and correct errors — this is free and can move your rate.
- Line up a cosigner early if your profile is thin; their credit and DTI will be evaluated too.
- Check rates with several lenders that offer prequalification through a soft credit inquiry. Confirm that the lender uses a soft pull before submitting your information, because not every lender offers the same rate-check process. A full application will generally require a hard credit inquiry.
- Compare APR, repayment term, fees, discounts, and total repayment cost — not just the advertised interest rate.
- Borrow only the gap — every dollar borrowed is repaid with interest, and a smaller loan strengthens your application.
Bottom line
Private student loans are approved and priced according to the borrower's or cosigner's creditworthiness, income, existing obligations, and other lender-specific criteria. This is why a cosigner is common among younger borrowers with limited credit and income.
File the FAFSA and use available grants, scholarships, work-study, and federal loans first. Consider a private student loan only for the remaining funding gap, compare offers from several lenders, and review the APR, repayment term, fees, discounts, and borrower protections before committing.

Confirm current federal loan rules with the Consumer Financial Protection Bureau and the U.S. Department of Education, and see the NASFAA overview of the 2026 loan-limit and program changes. Confirm current private-loan rates, fees, discounts, eligibility requirements, and repayment terms directly with each lender before borrowing.
Not always, but cosigners are very common among traditional undergraduates — at Citizens, 98% of undergraduate loans are cosigned. If you have established credit and income (more common for graduate students), you may be able to qualify on your own, subject to the lender's underwriting.
There is no universal minimum credit score across private student lenders. Many prefer applicants or cosigners with credit scores in at least the mid-600s, while the lowest rates generally require very good or excellent credit, sufficient income, and a strong overall financial profile.
Private lenders commonly offer both fixed and variable rates. Fixed rates remain unchanged for the life of the loan, while variable rates can increase or decrease according to the benchmark and adjustment terms stated in the loan agreement. Compare the current APR and long-term risk of each option.
Private lenders generally cap borrowing at your school-certified cost of attendance minus other aid received. That's a ceiling, not a target — borrow only what you actually need.
Some lenders offer prequalification using a soft credit inquiry, which generally does not affect your credit score. Confirm the type of inquiry before checking your rate. A formal application commonly requires a hard credit inquiry, which may cause a small, temporary change to your score.
