A family borrowing $30,000 through the federal Parent PLUS program this fall will pay roughly $3,400 more in interest over a standard 10-year repayment than a family that took out the same loan last year. The reason: starting July 1, 2025, new Parent PLUS loans carry a fixed rate of 9.07%, up from 8.05% the previous year and the highest rate attached to new federal parent borrowing since the 2006-07 academic year.
Undergraduate Direct Loans are also climbing, resetting to 6.52% from 5.50%. Graduate Direct Loans will carry a rate of 8.07%, up from 7.05%. None of these increases were voted on this spring. They are the automatic result of a formula Congress locked into law more than a decade ago, and they apply to every federal loan disbursed during the 2025-26 academic year.
Why rates rose and how the formula works
The rate-setting mechanism traces back to the Bipartisan Student Loan Certainty Act (H.R. 1911), signed into law in August 2013. Before that legislation, Congress periodically set student loan rates through standalone bills, a process that invited political brinkmanship every time a reset was due. The 2013 law replaced that approach with a market-indexed formula: each May, the Department of Education takes the high yield from the 10-year Treasury note auction held just before June 1 and adds a fixed statutory margin that varies by loan type.
For undergraduate Direct Loans, the add-on is 2.05 percentage points above the Treasury yield. For graduate Direct Loans, it is 3.60 points. For Parent PLUS loans, it is 4.60 points. Each loan type also has a statutory ceiling: 8.25% for undergrad, 9.50% for grad, and 10.50% for PLUS. Once set, the rate locks in for the life of every loan disbursed during that July-to-June window, regardless of what markets do afterward.
The Department of Education confirmed the 2025-26 figures in a Federal Register notice dated March 2, 2026, covering loans made under the William D. Ford Federal Direct Loan Program between July 1, 2025, and June 30, 2026. The underlying Treasury yield movements that drove the increase are documented in the Federal Reserve’s H.15 statistical release. Ten-year Treasury yields climbed through much of spring 2025, pushed higher by investor expectations about inflation, federal deficits, and the pace of Federal Reserve rate decisions.
How much more borrowers will actually pay
The jump hits Parent PLUS borrowers hardest in raw dollars. Under the standard 10-year repayment plan, a $30,000 Parent PLUS loan at 9.07% requires a monthly payment of about $382, compared with roughly $364 at last year’s 8.05% rate. Over the full repayment period, that gap adds up to approximately $3,400 in additional interest, bringing total interest costs above $15,800.
For a dependent undergraduate borrowing the annual maximum of $5,500 as a first-year student, the rate increase from 5.50% to 6.52% is smaller in absolute terms but still meaningful over time. On a $27,000 cumulative balance (the aggregate limit for a dependent undergraduate who borrows the maximum each year), the higher rate adds roughly $1,500 in total interest over a decade of repayment.
These figures assume borrowers stay on the standard plan. Borrowers who enter income-driven repayment (IDR) may pay more or less depending on their income and whether any remaining balance is eventually forgiven. Most IDR options, however, are structured around loans held by students, not parents. Parent PLUS borrowers can access the Income-Contingent Repayment plan only after first consolidating into a Direct Consolidation Loan, a step that resets the repayment clock and can increase total interest paid. Ongoing litigation over the SAVE repayment plan has also created uncertainty about which IDR pathways will be fully available going forward; borrowers should check studentaid.gov for the latest status before making consolidation decisions.
A decade of rate creep
When the market-indexed formula first took effect for the 2013-14 academic year, undergraduate Direct Loans carried a rate of 3.86% and Parent PLUS loans were set at 6.41%. Rates dropped even further during the pandemic: undergraduate loans disbursed in 2020-21 hit a historic floor of 2.75%, and PLUS loans bottomed out at 5.30%. Borrowers who locked in during those years got a deal that now looks extraordinary by comparison.
The climb since then has been steep, tracking the broader rise in Treasury yields as the Federal Reserve tightened monetary policy starting in 2022. The current 9.07% PLUS rate surpasses even the pre-formula era. In 2006-07, the last year PLUS loans exceeded 8%, Congress had set a flat rate of 8.5%. The formula was designed to give borrowers the benefit of low rates when markets cooperated; the tradeoff is that borrowers also absorb the full impact when yields rise.
What families should weigh before borrowing
At 9.07%, federal Parent PLUS loans are no longer the obvious default for families with strong credit. Some private lenders are currently offering fixed rates below the PLUS rate for well-qualified borrowers, though advertised ranges vary widely by lender and credit profile. Private loans, however, lack the federal protections that make PLUS borrowing a safety net: access to IDR (after consolidation), deferment and forbearance options, and potential eligibility for future forgiveness programs.
Families weighing their options should consider several concrete steps before the fall semester:
- Run the numbers on both sides. Compare the total cost of a PLUS loan at 9.07% against private loan offers using each lender’s actual rate quote, not just advertised ranges. Factor in origination fees: federal PLUS loans disbursed between Oct. 1, 2024, and Sept. 30, 2025, carry a loan fee of 4.228%, which is deducted from each disbursement before the money reaches the borrower.
- Borrow less if possible. At these rates, every dollar not borrowed saves roughly 50 to 60 cents in interest over a 10-year repayment. Families who can cover even part of the gap through savings, tuition payment plans offered by the school, or increased student employment reduce their exposure significantly.
- Understand the repayment timeline. PLUS loans enter repayment 60 days after the final disbursement for the academic year unless the parent requests a deferment while the student is enrolled. Parents who are not prepared for payments to begin that quickly can be caught off guard.
- Consider refinancing later, but borrow strategically now. Borrowers who take federal PLUS loans can explore refinancing with a private lender after graduation if rates fall or their credit improves. Refinancing converts the loan to a private product, which means giving up federal protections. That tradeoff may or may not make sense depending on individual circumstances.
- Watch for policy changes, but do not bank on them. As of June 2026, no pending legislation or regulatory proposal in the public record directly targets relief for the 2025-26 PLUS rate cohort. Borrowing decisions should be based on current terms, not speculation about future forgiveness.
What happens when the formula resets again
The rate formula resets in the spring of 2026 for loans disbursed starting July 1, 2026. If 10-year Treasury yields remain near their current levels or climb further, next year’s rates could push even closer to the statutory caps. For Parent PLUS loans, that ceiling is 10.50%, a threshold that once seemed theoretical but now sits only about 1.4 percentage points above the current rate.
Congress has shown little appetite to revisit the 2013 formula. Occasional proposals to cap rates or return to fixed statutory pricing have stalled in committee, and no bill with significant co-sponsorship has advanced in the current session. For now, the formula runs on autopilot, and the cost of borrowing for college tracks the same forces that drive mortgage rates, car loans, and the federal government’s own borrowing costs.
Families who need to borrow for the 2025-26 academic year are locked into the rates already published. The most productive use of the months before fall enrollment is to minimize the amount borrowed, compare federal and private options side by side, and build a repayment plan that accounts for the real cost of money at 6.52% or 9.07%, not the lower rates that may still appear in older planning guides and online calculators.
