Federal student loan rates for 2026-27

Rates on new federal loans are fixed for the life of the loan and reset every July 1 for new loans, based on the 10-year Treasury auction in May plus a fixed margin. The May 12, 2026 auction yield was 4.468%.

Loan, first disbursed July 1, 2026 to June 30, 2027RateLegal cap
Direct Subsidized and Unsubsidized, undergraduate6.52%8.25%
Direct Unsubsidized, graduate and professional8.07%9.50%
Direct PLUS (parents, and graduate students with older PLUS eligibility)9.07%10.50%

Autopay discount: from July 1, 2026 the Department of Education cut the rate by a full percentage point, instead of the usual 0.25 point, for Direct Loans on automatic payments. Borrowers enrolled by December 31, 2026 keep it through June 30, 2028. After that the calculator assumes the usual 0.25-point discount.

The repayment plans after July 1, 2026

The 2025 reconciliation law (P.L. 119-21) rebuilt federal repayment. For loans made on or after July 1, 2026 there are two plans:

  • Standard plan. Fixed payments over a term set by how much you owe: 10 years below $25,000, 15 years from $25,000, 20 years from $50,000 and 25 years from $100,000.
  • Repayment Assistance Plan (RAP). Payments are a share of your adjusted gross income: 1% if you earn $10,001 to $20,000, rising one point for every extra $10,000, up to 10% above $100,000. The payment drops by $50 a month for each dependent and is never less than $10. Any unpaid monthly interest is not charged, and if your payment cuts the principal by less than $50, the government makes up the difference, up to $50. Whatever remains after 360 qualifying payments (30 years) is forgiven.

Borrowers with no loans made on or after July 1, 2026 keep access to the classic 10-year standard plan, Income-Based Repayment (IBR), and the graduated and extended plans, and can opt in to RAP. The SAVE plan was ended by court order, and PAYE and ICR close on July 1, 2028; borrowers still in them by then are moved to RAP unless they pick another plan. Check your options at studentaid.gov or with your servicer.

A worked example

Owing $35,000 at 6.52% on the classic 10-year plan costs $397.77 a month and $12,733 in interest. The new tiered standard plan stretches the same balance over 15 years: $305.27 a month, but $19,949 in interest. On RAP with an AGI of $55,000 and no dependents, the rate is 5%, so the first payment is $55,000 × 5% ÷ 12 = $229.17. That is more than the $190 of monthly interest, so the balance still shrinks, and the payment rises as your income does.

Paying it off faster

Extra payments go straight to principal once interest is covered, and they shorten every plan except when forgiveness is the goal. If you work for a government or a qualifying nonprofit, Public Service Loan Forgiveness cancels the rest after 120 qualifying payments, so paying extra makes little sense. Otherwise, pay extra on the highest-rate loans first. Refinancing with a private lender can lower the rate for strong credit profiles but ends access to income-based plans, forgiveness and deferment.

Questions people ask

What is the student loan interest rate for 2026-27?

6.52% for undergraduate Direct Loans, 8.07% for graduate unsubsidized loans and 9.07% for PLUS loans first disbursed between July 1, 2026 and June 30, 2027.

How is the RAP payment calculated?

Your AGI times a percentage from 1% to 10% based on income, divided by 12, minus $50 for each dependent, with a $10 minimum. For AGI of $55,000 the percentage is 5%.

Is RAP better than the standard plan?

RAP lowers the payment when your income is modest compared with what you owe, and unpaid interest is not charged. If your income is high relative to your debt, the standard plan usually costs less in total. The comparison table shows both for your numbers.

Does interest accrue while I am in school?

Yes on unsubsidized and PLUS loans, and it is added to the balance when repayment starts. Subsidized loans do not charge interest while you are enrolled at least half-time and during the six-month grace period.

Is forgiven student debt taxable?

Forgiveness under Public Service Loan Forgiveness is tax-free. The federal exclusion for other forgiven student debt expired at the end of 2025, so forgiveness under an income-driven plan may count as taxable income. Check the rules for the year your balance is forgiven.
