Federal Student Aid set new interest rates for the 2026-27 academic year in a June 4 announcement, and the numbers are steep across every loan category. A parent who takes out a Direct PLUS Loan to help cover a child’s tuition this fall will pay 9.07 percent for as long as that loan exists — not an introductory rate, not a number that adjusts if the broader market shifts, but a fixed figure locked in at disbursement and never revisited for the life of the loan.
How the Rate Gets Set Every Summer
Federal student loan rates aren’t set by Congress or announced case by case; they’re calculated by a formula written into law. Each year’s rate equals the high yield from the final 10-year Treasury Note auction held before June 1, plus a fixed add-on that varies by loan type. This year, the Treasury’s May 12 auction produced a high yield of 4.468 percent. Add the statutory 2.05 percent add-on for undergraduate loans and the rate comes to 6.52 percent; add 3.60 percent for graduate unsubsidized loans and it’s 8.07 percent; add 4.60 percent for Direct PLUS loans — the category that covers both Parent PLUS and graduate PLUS borrowing — and the rate lands at 9.07 percent.
The add-on itself is fixed in statute and doesn’t move year to year, according to Federal Student Aid’s June 4 announcement; the only variable that changes the final rate is where the Treasury auction lands each May, which is why a rate can jump noticeably from one loan year to the next even though the underlying formula hasn’t changed at all.

Three Different Rates, One Fixed-for-Life Rule
Every federal Direct Loan disbursed between July 1, 2026 and June 30, 2027 falls into one of three tiers: 6.52 percent for undergraduates, 8.07 percent for graduate students borrowing unsubsidized loans, and 9.07 percent for PLUS borrowers. None of the three is anywhere near its statutory ceiling yet — the caps are 8.25 percent, 9.50 percent and 10.50 percent respectively, according to Federal Student Aid’s own explanation of how the rates and their limits work — but each tier has climbed steadily from the near-zero borrowing costs of the early 2020s. Because the rate is fixed at the moment of disbursement rather than for the borrower overall, a family sending one child through four years of college can end up holding four separate loans, each carrying whatever rate applied the summer it was taken out.
New Borrowing Limits Are Squeezing Parent PLUS at the Same Time
The higher rate isn’t the only change hitting parent borrowers this year. As of July 1, 2026, new Parent PLUS borrowers are capped at $20,000 per year per child, with a $65,000 lifetime limit, according to Federal Student Aid’s current Parent PLUS overview. Previously, Parent PLUS borrowing had no fixed annual or lifetime ceiling beyond the cost of attendance minus other aid, so a family covering an expensive private school could borrow whatever the gap required. Now a parent who hits the new cap and still has tuition left to cover has to look elsewhere — a private loan, the student’s own borrowing, or savings — at the same time the federal rate on the PLUS loan itself has climbed to 9.07 percent. The two changes land in the same academic year on purpose: a lower ceiling on how much a family can borrow federally, paired with a higher rate on whatever they do borrow, means Parent PLUS is doing noticeably less of the heavy lifting it used to for households counting on it to close a large tuition gap.
What 9.07 Percent Actually Costs Over Time
Run the math on a representative $25,000 Parent PLUS loan repaid over the standard 10-year term. At 9.07 percent, the monthly payment comes to roughly $317. Over the full repayment period, that adds up to about $38,100 paid back on the original $25,000 borrowed — more than $13,100 in interest alone, before counting the loan’s origination fee, which is deducted from the disbursement before the money ever reaches the school. A parent borrowing the same amount at the 6.52 percent undergraduate rate available to the student directly would pay several thousand dollars less in interest over the same term, which is part of why financial aid offices routinely encourage families to exhaust a student’s own federal borrowing capacity before turning to Parent PLUS. The $13,100 interest figure also assumes the loan is repaid on the standard 10-year schedule without a missed or deferred payment; PLUS loans that go into an income-driven or extended repayment plan, or that are deferred while a student stays in school, accrue interest the entire time and typically cost meaningfully more in total by the time they’re paid off.
Locking In Before Rates Reset Next July
Because the rate resets every July 1 based on the following spring’s Treasury auction, anyone borrowing between now and June 30, 2027 is locked to this year’s 9.07 percent, 8.07 percent or 6.52 percent — whichever tier applies. Next year’s rate depends entirely on where 10-year Treasury yields sit next May, a number nobody can know in advance. What’s fixed, and confirmed directly from Federal Student Aid’s own June 4 announcement, is that whatever a family borrows under this year’s window carries this year’s rate for as long as the loan exists, with no refinancing back to a lower federal rate if borrowing costs eventually come down.
