Educational analysis only, not financial advice; unless otherwise labeled inline, federal figures reflect loans first disbursed between July 1, 2026 and June 30, 2027, and private market rates reflect the week of July 13–18, 2026.
TL;DR — Quick Verdict
- Undergraduate Direct Loans carry a 6.53% fixed interest rate for 2026–27, set by the May 12, 2026 Treasury auction high yield of 4.468% plus a 2.05-point statutory margin.
- The average fixed interest rate on a 10-year private student loan was 7.92% during July 13–18, 2026, for borrowers with credit scores of 720 or higher, according to Credible data reported by Forbes Advisor.
- Federal Direct Loans charge a 1.057% origination fee; Direct PLUS Loans charge 4.228%. Sallie Mae and College Ave charge no origination fee, which narrows the effective gap on PLUS comparisons by roughly 4 points of principal.
- Grad PLUS was eliminated for new borrowers on July 1, 2026, and graduate borrowing is now capped at $20,500 per year and $100,000 aggregate ($50,000 and $200,000 for the 11 statutory professional degrees).
- Comparison result: on a $20,000 undergraduate balance, federal costs about $7,073 in interest over 10 years versus roughly $9,017 at the 7.92% private average — but the federal loan also carries forgiveness and income-driven options a private loan cannot replicate.
- Recommendation: exhaust federal eligibility first at the undergraduate level; run the private comparison seriously only for PLUS-substitution and post-cap graduate gaps, and only with a cosigner rate under roughly 6%.
A single bond auction on May 12, 2026 set the borrowing cost for millions of families. The U.S. Treasury’s 10-year note cleared at a high yield of 4.468%, and under the formula in Section 455(b) of the Higher Education Act, that number fixed federal student loan rates through June 30, 2027. Undergraduates now borrow at 6.53%, graduate students at 8.07%, and PLUS borrowers at 9.07%.
Private lenders operate on entirely different mechanics. Sallie Mae, College Ave, Ascent, and SoFi price each applicant individually against credit history and cosigner strength, producing advertised ranges that span from roughly 2.2% to nearly 18%. That spread is the whole problem: the same lender is simultaneously cheaper and far more expensive than the government depending on who is asking.
This analysis models the true cost of both paths — interest, origination fees, capitalization timing, and the dollar value of protections you forfeit when you leave the federal system. It also accounts for the July 1, 2026 restructuring under the One Big Beautiful Bill Act, which eliminated Grad PLUS and capped graduate borrowing for the first time. The comparison that mattered in 2024 no longer applies.
2026–27 Federal Rates and Fees: What You Actually Pay
Federal pricing is formulaic and public. Congress fixes each loan type at the 10-year Treasury high yield plus a statutory margin: 2.05 points for undergraduate Direct Loans, 3.60 points for graduate Direct Unsubsidized, and 4.60 points for PLUS. The Higher Education Act also caps these at 8.25%, 9.50%, and 10.50% respectively — ceilings that remain untested at current yields.
Fees complicate the headline number. Because of a standing budget sequestration order, Direct Subsidized and Unsubsidized Loans carry a 1.057% origination fee and PLUS loans carry 4.228%, both deducted proportionally from each disbursement. The Congressional Research Service notes the statutory fees are 1% and 4%; sequestration raised them, and they have stayed elevated since 2013.
Rates apply to loans first disbursed July 1, 2026–June 30, 2027. Fees apply to disbursements before October 1, 2026. Sources: Federal Student Aid Knowledge Center and Congressional Research Service. Net disbursement figures are original calculations.
One reconciliation note: several financial-aid outlets published the undergraduate rate as 6.52%. The statutory formula produces 4.468% + 2.05% = 6.518%, which the Higher Education Act rounds up to the nearest one-eighth of one percent, yielding 6.53%. Confirm the exact figure on your disclosure statement before modeling, since a single basis point compounds meaningfully across a four-year borrowing sequence.
How Private Lenders Price You — And Why the Range Is So Wide
Nothing about a private student loan is standardized. Sallie Mae’s published undergraduate rate sheet spans fixed offers from roughly 2.9% to 17.5% APR, and College Ave and Ascent advertise similar spreads. Where you land inside that band is decided by an underwriting model weighing credit score, income, debt-to-income ratio, school, program, and — decisively — whether a creditworthy adult cosigns.
Market averages tell a more useful story than advertised floors. For the week of July 13–18, 2026, the average fixed interest rate on a 10-year private student loan was 7.92% among borrowers with credit scores of 720 or higher who prequalified on Credible’s marketplace, per Forbes Advisor. Five-year variable-rate loans averaged 7.00% that same week. Note the qualifier: that 720-plus population is already the strong half of applicants, and the typical 19-year-old undergraduate is not in it without a cosigner.
Consider a specific case. A sophomore at a state university needs $12,000 beyond her federal eligibility. Applying alone with a thin file and no income, she is quoted 13.4% fixed. Her mother — 748 credit score, $96,000 salary, low utilization — cosigns, and the offer drops to 5.9%. Over a 10-year term, that difference is about $6,100 in interest. The loan did not change. The underwriting risk did.
Variable pricing adds a second layer. Most variable private loans track the 30-day average Secured Overnight Financing Rate, so a 7.00% starting rate is a snapshot, not a commitment. Lenders cap variable rates — Sallie Mae’s ceiling is 17.95% — but the cap is a disaster boundary, not a planning number. If your repayment horizon exceeds five years, treat variable offers as speculative and compare against the fixed-rate path in any payoff strategies ranked by interest saved.
Federal vs Private: Which Is Better for a $20,000 Undergraduate Gap?
Run the numbers on an identical $20,000 balance, 10-year standard amortization, no in-school payments modeled, and the federal path wins on straight cost. At 6.53%, total interest runs approximately $7,073 with monthly payments near $226. At the 7.92% private average, Forbes Advisor calculates roughly $9,017 in total interest at about $242 per month — a $1,944 spread.
Fees narrow it slightly. The federal borrower loses $211 to the 1.057% origination fee, while Sallie Mae and College Ave charge none, trimming the federal advantage to roughly $1,733 in true cost. That is real money, but it is not the deciding factor.
The deciding factor is optionality. Federal borrowers can enroll in the Repayment Assistance Plan, pause payments during unemployment, pursue Public Service Loan Forgiveness, and rehabilitate after default. Private lenders offer none of these as enforceable rights. Pricing that optionality is imprecise, but a borrower who spends even 18 months in a low-income period covered by income-driven repayment plans compared by cost typically recovers more than the entire $1,733 interest differential.
The comparison inverts only under specific conditions. A private fixed offer at 4.5% with a strong cosigner produces about $4,842 in interest on the same $20,000 — beating federal by roughly $2,231 even after accounting for the missing origination fee. Whether that trade is wise depends entirely on the borrower’s career volatility, a calculation explored further in refinancing savings and what is given up.
Verdict
For undergraduate borrowing, exhaust federal Direct Loans first without exception. The 6.53% interest rate beats the 7.92% private market average outright, and the protections are worth more than the rate gap even when a cosigner beats federal pricing. Private loans belong only in the gap above federal annual limits — and only at a fixed rate under 6% with a cosigner willing to stay on the note.
The Graduate Calculation Changed on July 1, 2026
Graduate students face a genuinely different question than they did last year. The One Big Beautiful Bill Act, signed July 4, 2025, eliminated the Grad PLUS program for new borrowers as of July 1, 2026 and imposed hard caps where none existed. General graduate programs are limited to $20,500 per year and $100,000 aggregate. The 11 statutory professional degree fields — medicine, law, dentistry, veterinary medicine, and similar licensed tracks — get $50,000 per year and $200,000 aggregate. A combined $257,500 lifetime federal cap applies across all student borrowing, excluding Parent PLUS.
Notably, the MBA is not classified as a professional degree under the rule, so business students borrow under the lower general graduate cap despite tuition that frequently exceeds it.

Here is the arithmetic that now forces the private conversation. A medical student at a private institution facing $95,000 in annual cost of attendance can access $50,000 federally. The remaining $45,000 per year has no federal source — Grad PLUS is gone. That gap goes to private lenders, family resources, or institutional aid, which reshapes every assumption in medical school debt repayment strategies. Students already enrolled before July 1, 2026 retain prior limits for up to three years, so the cliff is staggered rather than instant.
At 8.07% federal versus a cosigned private offer near 5.5%, a strong-credit graduate borrower now has a defensible case for private financing above the cap — a reversal from the pre-2026 default. The tradeoffs are laid out in Grad PLUS vs private loan comparison.
What Most Borrowers Get Wrong
Four errors show up repeatedly, and each is expensive.
Comparing interest rate to APR
Federal loans quote an interest rate; private lenders quote APR, which folds in fees. Because federal origination fees sit outside the quoted rate, a naive comparison of 9.07% federal PLUS against a 7.5% private APR understates the federal cost by roughly 4.228% of principal. Correct action: convert the federal loan to an effective APR by amortizing the origination fee across the repayment term before comparing anything. On Parent PLUS specifically, this shifts the answer often enough that Parent PLUS loan rates, fees, and repayment deserves its own analysis.
Treating a cosigner release as automatic
Sallie Mae and SoFi both permit cosigner release applications after 12 consecutive on-time payments, and borrowers hear “12 payments” as a guarantee. It is an application, subject to independent underwriting of the primary borrower. Consequence: a parent expecting to exit the obligation in year two remains liable in year eight. Correct action: assume the cosigner is on the note for the full term and plan accordingly.
Refinancing federal loans for a small rate improvement
Refinancing federal debt into a private loan is irreversible. A borrower trading 6.53% for 5.9% saves a few hundred dollars annually and permanently forfeits RAP eligibility, PSLF, deferment rights, and death-and-disability discharge. Correct action: refinance federal loans only if you have a stable, high income, no public-service career path, and a rate improvement exceeding roughly 200 basis points — and never before confirming your PSLF qualification and paperwork pitfalls.
Choosing in-school deferment without pricing capitalization
Deferred repayment on an unsubsidized or private loan lets interest accrue and then capitalize at the end of the grace period. Sallie Mae’s own disclosure illustrates the effect: a $10,000 loan under the Fixed Repayment Option with a four-year in-school period and a six-month grace can reach a total loan cost above $36,000 at the high end of its rate band. Correct action: make interest-only payments while enrolled, and understand the mechanics in deferment vs forbearance interest accrual.
Who Should Actually Consider a Private Loan?
Conditional logic beats blanket advice here. Private student loans make defensible sense in four situations and almost none others.
You have a cosigner with a 740-plus credit score producing a fixed offer at least 150 basis points below your federal rate, and your intended career carries low income volatility — engineering, actuarial work, established trades. The interest savings are real and your need for federal protections is genuinely low.
You are a graduate or professional student who has hit the new federal cap. There is no federal option above $100,000 or $200,000 aggregate. The choice is private borrowing, institutional aid, or not attending, and the calculus differs sharply by field — a point developed in law school debt vs lawyer salary analysis.
You are a parent facing the 9.07% Parent PLUS rate plus a 4.228% origination fee. Private parent loans from Sallie Mae and College Ave frequently price below this combination for well-qualified borrowers, making PLUS one of the few federal products routinely beaten on cost.
Your employer offers repayment assistance that applies to private debt. Many programs do not distinguish loan type, and the tax treatment covered in employer repayment benefits and tax rules can change the ranking entirely.
Conversely, skip private loans if your income is uncertain, you are pursuing public service, your credit is thin without a cosigner, or you have not yet checked your total borrowing against the salary-to-debt rule for borrowing limits. Undergraduates with any federal eligibility remaining should not be shopping private lenders at all.
Frequently Asked Questions
Can I still get a Grad PLUS loan in fall 2026?
Only under grandfathering. The Department of Education eliminated Grad PLUS for new borrowers as of July 1, 2026. Students who had already borrowed a federal loan for their current program before that date retain access to prior limits for up to three years or until program completion, whichever comes first. New enrollees are capped at $20,500 annually for general graduate programs and $50,000 for the 11 statutory professional degree fields.
Does the 1.057% origination fee apply to private loans?
No. The 1.057% figure applies to Direct Subsidized and Unsubsidized Loans, and 4.228% to Direct PLUS Loans, both through disbursements before October 1, 2026. Major private lenders including Sallie Mae, College Ave, and SoFi charge no origination fee, which is why comparing a federal interest rate directly against a private APR overstates the federal advantage by roughly 1 to 4 points of principal.
Is a 7.92% private fixed rate good?
It is the market average, not a good deal. Forbes Advisor reported 7.92% as the average fixed interest rate on 10-year private student loans during July 13–18, 2026, among borrowers with credit scores of 720 or higher. That sits above the 6.53% undergraduate federal rate. A private loan only outperforms federal borrowing when a cosigner pushes the offer materially below 6%.
What happens to my repayment options if I refinance federal loans privately?
You lose them permanently and cannot reverse the decision. Refinancing converts federal debt to private debt, forfeiting the Repayment Assistance Plan, remaining income-driven options, Public Service Loan Forgiveness eligibility, statutory deferment and forbearance rights, and death-and-disability discharge. Given that RAP offers forgiveness after 30 years of qualifying payments, borrowers with volatile income should treat federal refinancing as a last resort.
How We Researched This Article
Every interest rate, fee, and borrowing limit in this analysis was verified against a primary source in July 2026 rather than drawn from prior-year figures. Federal interest rates come from the Federal Student Aid Knowledge Center electronic announcement published June 4, 2026, which documents the May 12, 2026 Treasury auction high yield of 4.468% and the statutory margins applied to each loan type. Origination fee percentages and their sequestration history come from the Congressional Research Service report on federal student loan origination fees, updated January 9, 2026.
Borrowing caps, the Grad PLUS elimination, and repayment plan restructuring were confirmed through the U.S. Department of Education negotiated rulemaking announcement and cross-checked against NASFAA’s guidance for graduate students. Private market rates come from Forbes Advisor’s weekly survey of Credible marketplace prequalification data for the week of July 13–18, 2026, restricted to borrowers with credit scores of 720 or higher, supplemented by Sallie Mae’s published rate sheet.
All dollar figures in the comparison scenarios are modeled, not measured. Interest totals assume standard 10-year amortization, full disbursement at term start, no in-school payments, and no prepayment. Real borrowers with staggered disbursements, in-school interest payments, or autopay discounts will see different totals. The cosigner scenario in the private pricing section is illustrative and constructed from published rate bands rather than drawn from a specific loan file.
Two limitations deserve acknowledgment. First, private rate averages reflect prequalified applicants who self-selected into a marketplace and skew toward stronger credit than the full borrower population, so typical outcomes are likely worse than 7.92%. Second, origination fee percentages are scheduled to reset October 1, 2026, and the figures here apply only to disbursements before that date. Where secondary sources reported the undergraduate rate as 6.52%, we applied the statutory rounding formula and reported 6.53%, flagging the discrepancy inline rather than silently choosing one.
