Best Private Student Loans 2026: Rates, Cosigner Rules, Repayment Options — June 2026

Key Takeaways

Federal loans, scholarships, grants, and work-study come first: private loans are a last-mile funding tool, not a first resort.
Choosing deferred repayment on a $15,000 loan at 7% over 10 years costs you roughly $1,400 more in total interest than making interest-only payments in school.
Most undergraduates need a cosigner to qualify for private loans; a creditworthy cosigner can reduce your APR by 1 to 3 points, which adds up to thousands over a 10-year term.

The bottom line

Private student loans fill the funding gap after you have maxed federal loans, scholarships, grants, and work-study. They do not come with income-driven repayment, PSLF eligibility, or federal forbearance. Used strategically, in the right amount and with a strong repayment plan, they are a reasonable tool. Used carelessly, they can become expensive debt with few options if your income falls short after graduation.

Federal loans first: the rule that saves thousands

⚠️ Important

Before comparing any private loan, confirm you have used every dollar of your federal loan eligibility. For the 2025-26 academic year, undergraduate direct loan limits are $5,500 to $7,500 per year depending on dependency status and year in school. Graduate students can borrow up to $20,500 per year in Direct Unsubsidized loans. Federal loans carry income-driven repayment eligibility, PSLF eligibility, and standardized forbearance that private loans do not. Use them first. Private loans are a last-mile tool, not a first line of funding.

The priority order for funding higher education is:

Scholarships and grants (no repayment required)
Work-study and employment income (no debt)
Federal Direct Subsidized loans (interest paused while enrolled at least half-time)
Federal Direct Unsubsidized loans
Parent PLUS loans (see the parent loans guide for trade-offs)
Private student loans

Private loans appear last on this list because they are last in this priority. They cost more, protect less, and leave you with fewer options if your post-graduation income is lower than expected.

What the repayment choice costs you in school

This is one of the most consequential decisions in private student borrowing: what to pay while you are still enrolled.

Real math: $15,000 at 7% APR over 10 years by in-school repayment type

Deferred repayment (no payments in school): Interest accrues during a 4-year undergraduate program and a 6-month grace period. At 7%, that is roughly $4,725 in accrued interest added to your principal before repayment begins. Starting balance at repayment: approximately $19,725. Monthly payment: $229. Total paid over 10 years: $27,478. Total interest paid: $12,478.

Interest-only payments in school: You pay roughly $87.50 per month during a 4-year program (4 years x 12 months x $87.50 = $4,200 total in-school payments). Balance at repayment start: $15,000 (no capitalization). Monthly payment: $174. Total paid: $4,200 in school + $20,880 in repayment = $25,080. Total interest paid: $10,080.

Immediate full repayment in school: Payments begin right away, reducing principal faster. Total interest paid over the loan life is lowest. Best for borrowers with part-time income or family support during school.

Savings from interest-only vs. deferred: approximately $2,398 in total interest over the life of the loan, plus lower monthly payments in repayment.

Verify current APR ranges with each lender before modeling your own numbers. These figures use a fixed 7% APR for illustration.

The practical takeaway: if you can afford to pay even interest-only while in school, do it. It meaningfully reduces your balance at graduation and keeps monthly payments manageable.

Do you need a cosigner?

Most undergraduates need a cosigner because they have limited credit history and little to no income. Graduate students with established credit and full-time employment may qualify without one. Here is how to think through the decision:

You likely need a cosigner if:

You are a first- or second-year undergraduate
You have little or no credit history (less than 2 years of accounts)
Your annual income is under $20,000
Your credit score is below 680

A cosigner can help even if you technically qualify, because:

A creditworthy cosigner (score 740+) can reduce your APR by 1 to 3 points
On $15,000 at 7% vs. 5.5% over 10 years, that difference is roughly $1,200 in total interest
A lower rate also means a lower monthly payment, which matters if your post-graduation income is uncertain

What cosigning means for the cosigner:

They are equally and fully liable for the loan. If you miss payments, they are responsible.
The loan appears on their credit report and affects their debt-to-income ratio.
This can affect their ability to get a mortgage, car loan, or other credit.
Discuss this fully before asking anyone to cosign.

Cosigner release: free your cosigner after meeting requirements

A cosigner release lets you remove the cosigner from the loan after you meet the lender's criteria, typically a set number of on-time payments plus a credit and income review. Release timelines vary:

College Ave: 24 consecutive on-time payments, subject to credit review
Sallie Mae: After primary repayment period begins and other criteria are met; verify current terms at salliemae.com
Earnest: Does not currently offer cosigned private student loans; confirm availability directly
Ascent: Cosigner release available after certain payment thresholds; verify terms at ascentfunding.com
Citizens Bank: Cosigner release after 36 months; confirm current terms at citizensbank.com

Until the release is granted, the cosigner's liability and credit exposure remain. Make it a goal to pursue release as soon as you qualify.

In-school repayment options, compared

Repayment option	Monthly payment in school	Interest capitalizes?	Best for
Full deferment	$0	Yes, fully	Borrowers with zero income in school
Interest-only	~$87.50 on $15K at 7%	No	Borrowers with part-time income
Fixed small payment	$25 to $50 (varies by lender)	Partially reduced	Borrowers with limited income
Immediate full payment	Full amortizing	No	Borrowers with employment or family support

Ask each lender which in-school options they offer before signing. Not all lenders offer all four tiers.

Grace period comparison

Most private lenders offer a 6-month grace period after graduation before repayment begins. Some offer extended grace for medical or dental residencies (verify with each lender). Interest typically continues to accrue during the grace period. If your lender capitalizes interest at the end of the grace period, your starting balance in repayment will be higher than your original borrowed amount. Know whether your lender capitalizes grace-period interest before you sign.

Top picks, detailed

College Ave: Best for undergraduates and no-fee borrowing

College Ave charges no application fee, no origination fee, and no prepayment penalty. It offers four in-school repayment options (deferred, interest-only, fixed payment, full payment) and cosigner release after 24 months of on-time payments. Loan terms range from 5 to 15 years. Rates are credit-dependent; get a rate estimate with a soft inquiry at collegeave.com.

Who should apply: Undergraduates with a creditworthy cosigner who want flexible in-school payment options and a path to cosigner release.

Who should skip: Borrowers who need longer terms or who have strong solo credit and want a lender that rewards merit-based underwriting more aggressively.

Watch Out: College Ave's lowest published APRs go to borrowers with excellent credit and a cosigner. If you apply without a cosigner and a limited credit history, your rate will be toward the high end of the range. Get a rate estimate before committing to compare with other lenders.

Sallie Mae: Best for clear in-school interest-only option

Sallie Mae is one of the largest private student lenders in the United States. It offers undergraduate, graduate, and specialty loans (medical, dental, law, MBA). The Smart Option Student Loan offers three in-school repayment choices: deferred, interest-only, and fixed payment. Cosigner release is available after meeting payment and creditworthiness criteria; verify current terms at salliemae.com.

Who should apply: Borrowers who want a large, established lender with clear in-school repayment options and a wide range of school types covered.

Who should skip: Borrowers who prioritize low fees above all else; compare total cost across lenders. Federal loan borrowers who have not yet exhausted their federal limits.

Watch Out: Sallie Mae's variable rates can be attractive at origination but carry long-term payment risk on a 10- to 15-year term. If you choose a variable rate, confirm the rate cap and calculate your payment at the cap before signing.

Earnest: Best for graduate students with strong credit

Earnest's merit-based underwriting looks beyond credit score to your education, savings rate, income trajectory, and employment. This can help graduate students with solid profiles who do not yet have a long credit history. Earnest offers flexible repayment terms and no fees. Verify current product availability (cosigner options vary) at earnest.com.

Who should apply: Graduate students with established credit, steady income, and no need for a cosigner who want a lender that rewards financial responsibility holistically.

Who should skip: Undergraduates with limited credit who need a cosigner (verify Earnest's current cosigner product availability directly). Borrowers who need more than 15 years to repay.

Ascent: Best for professional programs

Ascent specifically serves medical, dental, law, and MBA students with products tailored to the financial profile of professional school: large loan amounts, deferred repayment through training, and grace periods that match residency timelines. Ascent also offers non-cosigned loans for graduate students who meet credit and income thresholds. Verify current APR ranges and program availability at ascentfunding.com.

Who should apply: Medical, dental, or law students with high borrowing needs who want in-school deferment through residency and a lender that understands professional school timelines.

Who should skip: Undergraduates or community college students (Ascent's non-cosigned products have specific eligibility requirements). Anyone eligible for NHSC or PSLF with federal loans.

Watch Out: Professional school borrowers face the highest private loan balances in higher education. A medical student borrowing $50,000 per year at 7% for 4 years, deferred through a 3-year residency, could have a capitalized balance exceeding $280,000 before repayment begins. Calculate this number before borrowing. Federal Graduate PLUS loans offer income-driven repayment and PSLF eligibility that private loans do not.

Discover Student Loans: Best for cashback reward at graduation

Discover offers a one-time 1% cashback reward on the loan principal if you graduate. This is not a rate reduction but a rebate paid after you complete your degree. Discover charges no fees and offers a 6-month grace period. Verify current APR ranges and cashback program terms at discover.com, as program terms can change.

Who should apply: Borrowers who want a no-fee lender with a straightforward cashback incentive tied to graduation.

Who should skip: Borrowers who need a cosigner release timeline shorter than Discover currently offers; verify current terms directly.

Citizens Bank: Best for multi-year approval

Citizens Bank offers a multi-year approval feature for undergraduate borrowers, meaning you can be approved for your total program borrowing needs upfront and receive funds each year without reapplying. This reduces credit inquiries and simplifies the annual borrowing process. Cosigner release is available after 36 months; verify current terms at citizensbank.com.

Who should apply: Undergraduates who want to lock in their borrowing approval across all four years without annual reapplications.

When this recommendation changes

When the answer flips

Private loan rankings shift when: (1) a lender changes its APR range, fee structure, or underwriting criteria; (2) federal loan limits are adjusted by Congress, changing how much of your funding gap is left for private loans; (3) interest rates move significantly, which affects variable-rate offers more than fixed; (4) your credit profile changes between years, which can unlock better rates at different lenders than you used previously. Revisit lender comparisons each academic year before borrowing new funds.

How we ranked

SwitchWize ranked private student loan lenders on five factors: APR range (published low-to-high for fixed rates), fee structure (origination, application, prepayment, late fees), in-school repayment flexibility (how many options offered), cosigner options and release terms, and specialty program availability (professional school programs, medical residency deferment). Lenders receive affiliate compensation for applications made through SwitchWize links. This compensation does not affect our rankings. All rate claims should be verified directly with each lender, as rates and eligibility change frequently.

Frequently Asked Questions

Should I take out private student loans before using up my federal loan limit?

No. Federal Direct Subsidized and Unsubsidized loans should be exhausted first. They come with income-driven repayment options, PSLF eligibility, and federal forbearance. Private loans have none of these protections. Use scholarships, grants, work-study, and federal loans in that order before turning to private lenders.

Do I need a cosigner for a private student loan?

Most undergraduates need a cosigner because they have limited credit history and income. Graduate students with established credit and employment may qualify without one. A cosigner typically improves the rate and approval odds significantly, but the cosigner is fully liable for the loan until released.

What is the difference between deferred and interest-only repayment in school?

Deferred repayment means you make no payments while in school, but interest accrues and capitalizes (is added to your balance) when repayment begins. Interest-only payments keep the balance from growing but do not reduce principal. Fixed payments while in school reduce both. Each choice has a different long-term cost.

How do I compare private student loan APRs when they show wide ranges?

The low end of a published APR range typically goes to borrowers with excellent credit and a cosigner. The high end goes to thin-file or lower-credit borrowers. Get a rate quote with a soft inquiry (no credit score impact) to see your personalized rate before comparing across lenders.

Can private student loans be forgiven?

No. Private student loans have no forgiveness programs equivalent to PSLF or IDR forgiveness. Some lenders offer limited discharge in cases of death or permanent disability, but the terms vary widely and must be confirmed with each lender directly.

What happens if I cannot make my private student loan payments?

Contact your lender immediately. Most private lenders offer some form of hardship forbearance (typically 12 months maximum over the life of the loan) at their discretion. Unlike federal loans, there is no standardized program and no income-driven payment option. Missing payments damages your credit and can trigger collections.

Do private student loans have grace periods after graduation?

Grace periods vary by lender. Most offer a 6-month grace period after graduation, during which you are not required to make payments, though interest may continue to accrue. Some lenders offer longer grace periods for medical or dental residencies. Verify the grace period terms before choosing a lender.
