The standard advice is simple: exhaust federal loans before considering private. It is good advice. Here is the detailed reasoning -- plus the cases where private loans make more sense than the rule suggests, and how to evaluate the comparison for your specific situation.
Federal Student Loans: Key Features
| Feature | Direct Subsidized | Direct Unsubsidized | Parent PLUS |
|---|---|---|---|
| 2026-27 rate | 6.52% | 6.52% undergrad / 8.07% grad | 9.07% |
| Rate type | Fixed for life of loan | Fixed for life of loan | Fixed for life of loan |
| Credit check | No | No | Yes (adverse credit only) |
| Interest during school | Government pays | Accrues to borrower | Accrues to borrower |
| Origination fee | 1.057% | 1.057% | 4.228% |
| Annual limit | $3,500-$5,500 (year-dependent) | $20,500 grad / $50,000 professional | $20,000 per student |
Parent PLUS Loans (for parents of dependent undergraduates) carry a 9.07% rate for 2026-27 and include a 4.228% origination fee -- making them significantly more expensive than Direct Subsidized and Unsubsidized Loans on a net cost basis.
What Changed on July 1, 2026
The One Big Beautiful Bill Act and the Department of Education's implementing rules reshaped federal student lending as of July 1, 2026. Anyone comparing federal and private loans for the 2026-27 year is comparing against a different federal system than existed a year ago:
- Grad PLUS is eliminated for new borrowers. A narrow legacy exception applies to students continuously enrolled in the same program at the same institution who received a Direct Loan for that program before July 1, 2026 -- for up to three more academic years.
- Graduate borrowing is capped at $20,500/year and $100,000 aggregate ($50,000/year and $200,000 for certain professional programs), with a $257,500 lifetime cap across all Direct Loans.
- Parent PLUS is capped at $20,000 per student per year and $65,000 per student lifetime, replacing the old cost-of-attendance model.
- The SAVE plan is gone. Borrowers who take out any new loan on or after July 1, 2026 have exactly two repayment options: the new Repayment Assistance Plan (RAP) or the Tiered Standard Plan.
- New Parent PLUS loans cannot enroll in RAP, and therefore have no pathway to Public Service Loan Forgiveness.
The practical effect for graduate and professional students is that private loans are no longer a supplement to federal borrowing -- for many programs they are now a structural necessity, because the federal caps no longer reach the cost of attendance.
Federal Protections You Cannot Get With Private Loans
The rate is not the only -- or even the primary -- reason to prefer federal loans. The protections are often worth more than any rate differential:
Income-Driven Repayment (IDR): For any loan first disbursed on or after July 1, 2026, the only income-driven option is the Repayment Assistance Plan (RAP), which sets payments at 1-10% of adjusted gross income with a $10 minimum, reduces the payment by $50 per dependent, and forgives any remaining balance after 30 years. Borrowers whose loans all predate July 1, 2026 keep access to IBR (and, until 2028, PAYE and ICR). SAVE has been eliminated. Whichever plan applies, the principle holds: if your income falls, your federal payment falls. Private loans have no equivalent -- if you cannot make the private payment, you are in default.
Public Service Loan Forgiveness (PSLF): Federal loans held in qualifying repayment plans can be forgiven after 120 qualifying payments (10 years) while working full-time for a qualifying government or nonprofit employer. Private loans are categorically ineligible. For borrowers planning careers in government, education, healthcare, or the nonprofit sector, PSLF eligibility can be worth hundreds of thousands of dollars in forgiveness.
IDR Forgiveness: Remaining federal balances may be forgiven after 20-25 years on the legacy IDR plans, or after 30 years under RAP. Private loans have no forgiveness mechanism at all.
Federal Forbearance and Deferment: Federal loans offer multiple forbearance and deferment options for economic hardship, unemployment, military service, and other qualifying circumstances. Interest may or may not accrue depending on the loan type and situation. Private loan hardship programs are lender-specific, often less generous, and not guaranteed.
Death and Disability Discharge: Federal loans are discharged upon the borrower's death or total and permanent disability. Private loan treatment varies significantly by lender and may not discharge in these circumstances, potentially leaving cosigners liable.
Private Student Loans: When They Make Sense
Given the protections above, the cases where private loans make financial sense are more specific than generally advertised:
Creditworthy borrowers who have exhausted federal limits: Federal Direct Loan limits for dependent undergraduates run $5,500-$7,500/year ($31,000 aggregate). Graduate students are now capped at $20,500/year and $100,000 aggregate, and Grad PLUS -- which previously covered the gap up to full cost of attendance -- no longer exists for new borrowers. For most graduate and professional programs, that cap will not cover the bill, and private loans fill a gap that federal lending simply no longer reaches. A creditworthy graduate student who qualifies for private loans at 5-6% should still weigh that against the 8.07% federal unsubsidized rate -- but only after exhausting the federal allocation, and only if PSLF eligibility is not a factor.
Borrowers with excellent credit and no PSLF eligibility: A borrower with a 780 credit score, a high-paying stable job in the private sector, and no aspirations for public service may qualify for private loan rates of 4-5% -- meaningfully below federal rates. For this borrower, who needs no IDR protection or forgiveness, the rate savings are real and federal loans' protections are not utilized.
Parent PLUS replacement: For parents who would otherwise take Parent PLUS Loans at 9.07% plus a 4.228% origination fee, private parent loans may offer significantly lower rates to those with strong credit. Two things sharpen this since July 1, 2026: Parent PLUS is now capped at $20,000 per student per year and $65,000 lifetime, so borrowing above the cap requires a private loan regardless of preference; and new Parent PLUS loans are ineligible for RAP, which removes the PSLF pathway that was previously the strongest argument for keeping them federal.
The Refinancing Decision: Distinct from the Origination Decision
The decision to refinance existing federal loans into private loans is separate from the origination decision and deserves its own analysis. Many borrowers who appropriately took federal loans during school later consider refinancing to a lower private rate once they have stable employment.
The refinancing calculus: rate savings must exceed the loss of federal protections' value. If you have $60,000 in federal loans at 6.5%, are in a stable private-sector career earning $90,000, have no PSLF eligibility, and could refinance to 4.5%, the $1,200/year interest savings over 10 years is approximately $12,000. Against that, you lose IDR protection (which you might not use given your income) and forgiveness eligibility (which is 20-25 years away and uncertain).
For most borrowers in stable, well-compensated private-sector careers with manageable debt-to-income ratios, this trade-off may favor refinancing. For anyone with PSLF eligibility or uncertain income, it almost certainly does not.
Private Loan Rates: What to Expect
Private student loan rates vary significantly by credit profile and lender:
- Excellent credit (760+): approximately 4.5-6.5% fixed
- Good credit (700-759): approximately 6-9% fixed
- Fair credit (640-699): approximately 9-13% fixed
- Variable rates: typically lower initially but subject to change
For undergraduates without established credit, most private loans require a creditworthy cosigner. The cosigner is equally liable for the debt -- if the student cannot pay, the cosigner is legally obligated. This is a significant commitment for parents who cosign private student loans, particularly if the loans are large and the career outcomes uncertain.
Making the Decision: A Practical Framework
Work through these questions in order:
- Have you submitted the FAFSA and maximized your federal subsidized loan eligibility? (Always do this first)
- Do you have remaining need that unsubsidized federal loans can cover at 6.52% (undergrad) or 8.07% (grad)? (Use them before private)
- Are you a graduate student at the $20,500 annual cap, or a parent at the $20,000 Parent PLUS cap? (Grad PLUS is gone for new borrowers; compare private rates for anything above the cap)
- Do you have PSLF eligibility or plan a public service career? (If yes, federal loans are almost always preferable regardless of rate)
- Is your income stable and high enough that IDR protection is unlikely to be needed? (If yes, the federal protections have lower value)
Frequently Asked Questions
Can I mix federal and private student loans?
Yes -- and this is common. Many borrowers use federal loans up to the available limit and supplement with private loans if additional funding is needed. They are managed separately, with different servicers, rates, and repayment terms. Keeping track of both is the borrower's responsibility; the government does not consolidate or combine federal and private loan information.
What happens to my private student loans if I die or become disabled?
Federal loans are discharged. Private loans vary dramatically by lender. Some private lenders now offer death and disability discharge provisions, but these are not required or universal. If a cosigner is on the loan, they may remain liable after the primary borrower's death or disability depending on the lender's policies. Review your private loan terms carefully, particularly if you have a cosigner.
Can private student loans be included in bankruptcy?
Student loan discharge in bankruptcy (both federal and private) requires demonstrating "undue hardship" under the Brunner test -- a difficult standard that historically was rarely met. The Department of Justice updated its bankruptcy guidance in 2022 to make federal loan discharge somewhat more accessible; private loan discharge remains lender-specific and difficult. Student loan bankruptcy discharge is not a viable planning strategy for most borrowers.
Are private student loan interest rates fixed or variable?
Both options exist. Fixed rates are constant for the life of the loan, providing predictable payments. Variable rates start lower but can increase over time based on SOFR or LIBOR-linked benchmarks. For loans with long repayment timelines (10+ years), fixed rates provide more certainty. Variable rates may make sense for shorter repayment timelines or if you expect to refinance before rates increase significantly.
What documents do I need to apply for a private student loan?
Typically: proof of enrollment or acceptance at an eligible school, Social Security number, income information (or cosigner's income if you lack your own), and basic personal information. Private lenders will run a credit check and may require additional documentation depending on your financial profile. The application process is similar to other consumer credit applications and can often be completed online in under 30 minutes.
