Your student loan interest rate is the single number that decides how much the debt grows while you sleep. Federal and private loans set that number in completely different ways, and the gap between them is where most borrowers either save or lose real money. Here is the 2026-27 federal lineup, how the rate is built, and what it means if you are thinking about refinancing.

Federal Rates for 2026-27

These are fixed rates for loans first disbursed between July 1, 2026 and June 30, 2027. Once your loan is disbursed, the rate is locked for the life of that loan.

Loan typeBorrower2026-27 rate2025-26 rate
Direct SubsidizedUndergraduate6.52%6.39%
Direct UnsubsidizedUndergraduate6.52%6.39%
Direct UnsubsidizedGraduate or professional8.07%7.94%
Direct PLUSParents and graduate students9.07%8.94%

Every tier rose about 0.13 points year over year. The change is small, but on a $40,000 balance it adds a few hundred dollars of interest over the life of the loan. Graduate and PLUS borrowers feel it most, because their rates already sit well above the undergraduate level.

How the Federal Rate Is Set

Congress does not pick these numbers. Each May the Treasury holds a 10-year note auction, and the high yield becomes the base. For 2026 that base was 4.47%. A statutory add-on is then layered on by loan type:

  • Undergraduate loans: base plus 2.05%, capped at 8.25%
  • Graduate loans: base plus 3.60%, capped at 9.50%
  • PLUS loans: base plus 4.60%, capped at 10.50%

The caps matter because they are the ceiling the formula can never cross, even if the Treasury auction spikes. The result is announced in early summer and applies to every loan disbursed the following July through June. Your existing loans are never re rated, which is why a borrower with three degrees can be carrying three different fixed rates at once.

Private Loan Rates Work Differently

Private student loans are not tied to the Treasury. Each lender sets its own rate based on your credit score, your income, whether you have a co-signer, and whether you pick a fixed or variable product. As of 2026, well qualified borrowers can see fixed private rates that beat the federal 6.52% to 9.07% band, while weaker credit profiles can land well above it. Variable private rates start lower but can climb as the market moves, which is the opposite of the federal fixed model.

The trade off is not about rate alone. A private loan trades away every federal protection: income-driven payments, deferment, forbearance, and forgiveness. Our consolidation vs refinancing guide breaks down exactly when that trade is worth it and when it is a trap.

How to Find Your Own Rate

Your rate is printed on the promissory note you signed and on every monthly statement. You can also pull it from StudentAid.gov under My Aid for federal loans, or from the lender portal for private ones. Do not guess. The rate drives both your monthly payment and the total interest you will ever pay, so it is the first thing to confirm before you run any repayment math. Our interest calculation guide shows exactly how servicers turn that rate into a daily balance.

What the Rate Means for Refinancing

The 2026-27 federal rates sit high enough that many private lenders can offer a lower fixed number, especially to borrowers with strong credit. That is genuinely attractive if your income is stable and you will never need an income-driven plan or Public Service Loan Forgiveness. But refinancing is permanent: once federal loans become private, the federal safety net is gone and you cannot get it back. If your payment feels unmanageable rather than merely expensive, the cheaper fix is usually an income-driven plan, not a refinance. Our guide to lowering your payment ranks every lever from free to final.

The Rate Is Fixed, the Decision Is Not

Federal rates lock on disbursement, but your response to them is always live. A higher rate simply raises the value of paying extra early, of picking the right repayment plan, and of weighing refinance only when your credit and income can clear the federal hurdle. Know the number, run it through a calculator, and decide from the total cost, not the headline.

Frequently Asked Questions

What are the federal student loan interest rates for 2026-27?

For loans first disbursed from July 1, 2026 through June 30, 2027, the fixed rates are 6.52% for Direct Subsidized and undergraduate Unsubsidized loans, 8.07% for graduate Unsubsidized loans, and 9.07% for all Direct PLUS loans. Each is fixed for the life of that loan, so the rate you get the day it is disbursed never changes.

Why did student loan rates go up for 2026-27?

Federal rates are tied to a May Treasury auction of 10-year notes. The 2026 add-on yielded a 4.47% base, and the statutory formula added 2.05% for undergraduates, 3.60% for graduate loans, and 4.60% for PLUS. That lifted every tier by about 0.13 points over the 2025-26 rates of 6.39%, 7.94%, and 8.94%.

Are federal student loan rates fixed or variable?

Fixed. Each loan is locked at the rate set the year it is disbursed, and it stays there until the loan is paid off. The rate on a new loan changes every July, but your existing loans are untouched. This is the opposite of most private loans, where a variable rate can move with the market.

Should I refinance to get a lower rate?

Only if you are comfortable giving up federal protections, because refinancing replaces federal loans with a private one and ends access to income-driven plans, deferment, and forgiveness. Borrowers with strong credit and steady income can beat 6.52% to 9.07% in the private market, but anyone who might need an IDR plan or PSLF should keep their federal loans as they are.
