Federal Student Loan Interest Rates for 2026–27: How They Are Set and What They Cost

For federal student loans first disbursed between July 1, 2026, and June 30, 2027, the fixed interest rate is 6.52% for undergraduate Direct Subsidized and Unsubsidized loans. Graduate students pay a fixed rate of 8.07% on Direct Unsubsidized loans, while parents borrowing through Direct PLUS loans face a fixed rate of 9.07%. These rates, published by the Department of Education at fsapartners.ed.gov, remain fixed for the life of the loan and directly determine how much interest accumulates while a borrower repays the debt.

These figures dictate the borrowing costs for millions of families planning for the upcoming academic year. Many families mistakenly believe that federal student loan rates are variable or negotiable based on credit scores, but every student borrower receives the same fixed rate regardless of financial need or credit history. For a dependent undergraduate borrowing the maximum first-year limit of $5,500 under these 2026–27 rates, interest begins accruing immediately on any unsubsidized portion, increasing the total balance before the student even graduates.

Key takeaways

• For the 2026–27 academic year, undergraduate federal student loans carry a fixed interest rate of 6.52% for both subsidized and unsubsidized options.
• Graduate students face an 8.07% interest rate on unsubsidized loans, while parents borrowing through Parent PLUS loans pay a fixed rate of 9.07%.
• Federal student loan rates are determined by adding a fixed margin to the 10-year Treasury note auction yield, which was 4.468% on May 12, 2026.
• Dependent undergraduates can borrow up to $5,500 in their first year, with a lifetime aggregate limit of $31,000 according to studentaid.gov.
• CollegesRef data shows a median average net price of $10,437 for public colleges compared to $27,167 for private nonprofit institutions.

Federal Student Loan Interest Rates for the 2026–27 Academic Year

Federal student loan interest rates change every summer. For loans first disbursed on or after July 1, 2026, and before July 1, 2027, the Department of Education has established new fixed rates that remain locked for the life of each loan. Borrowers can find these rates detailed on their financial aid award letters or by logging into their studentaid.gov dashboard.

Families planning for the upcoming school year must evaluate these borrowing costs alongside the actual net price of their chosen institution. To compare these figures without creating an account, families can use the CollegesRef College Cost Estimator. This tool displays a college's published tuition alongside its average net price and median graduate earnings, though it does not calculate individual loan interest payments.

Undergraduate Subsidized and Unsubsidized Loan Rates

For undergraduate borrowers, the interest rate for both Direct Subsidized Loans and Direct Unsubsidized Loans is 6.52% for the 2026–27 academic year. This rate applies to all undergraduate students regardless of financial need, though need determines whether a student qualifies for the subsidized version. According to the official announcement on fsapartners.ed.gov, this rate is fixed for the lifetime of the loan, meaning the interest rate will not fluctuate with market conditions in future years.

When reviewing a financial aid offer, students should look for the specific line items labeled "Direct Subsidized Loan" and "Direct Unsubsidized Loan" to identify their exact allocations. If the terms on the offer letter are unclear, families should contact the campus financial aid office to request a revised breakdown of financial aid terms explained in plain language.

Graduate Unsubsidized Loan Rates

Graduate and professional students face higher borrowing costs than undergraduate students. For the 2026–27 academic year, the interest rate for Direct Unsubsidized Loans for graduate students is 8.07%. This rate is also fixed for the life of the loan.

According to studentaid.gov, graduate students are subject to different annual borrowing limits than undergraduates. For new borrowers starting July 1, 2026, graduate students may borrow up to $20,500 per year in Direct Unsubsidized Loans, up to an aggregate limit of $100,000. Professional students have an annual limit of $50,000 and an aggregate limit of $200,000. Graduate students should check their school's cost of attendance budget to calculate exactly how much of this limit they need to utilize.

Parent PLUS Loan Interest Rates

Parents who borrow to help fund their undergraduate child's education will pay the highest rate among the federal direct loan programs. For the 2026–27 academic year, the interest rate for Direct PLUS Loans for parents is 9.07%.

According to studentaid.gov, Parent PLUS borrowing for loans first disbursed on or after July 1, 2026, is capped at $20,000 per year and $65,000 in total per dependent student. Parents must complete a separate application and undergo a basic credit check to secure a PLUS loan. To calculate the impact of this 9.07% rate, parents can multiply their desired loan amount by 0.0907 to determine the approximate amount of interest that will accumulate during the first year alone.

How Are Federal Student Loan Interest Rates Set Each Year?

Federal student loan interest rates do not depend on an applicant's credit score or family income. Instead, Congress establishes federal student loan interest rates through a strict statutory formula tied directly to the financial markets. Every spring, the government determines the rates for the upcoming academic year, which then remain fixed for the entire life of those specific loans.

The 10-Year Treasury Note Auction Connection

The foundation of the federal student loan interest rate formula is the final auction of the 10-year U.S. Treasury note held before June 1 of each year. According to the U.S. Department of Education, the high yield determined at this specific May auction serves as the benchmark rate for all federal student loans disbursed during the subsequent award year, which runs from July 1 through June 30.

For the 2026–27 academic year, the pivotal auction occurred on May 12, 2026. The high yield from this auction was established at 4.468%, as documented by the Federal Student Aid office at https://fsapartners.ed.gov/knowledge-center/library/electronic-announcements/2026-06-04/interest-rates-federal-direct-loans-first-disbursed-between-july-1-2026-and-june-30-2027. This single percentage is the starting point for calculating what families will pay. Families tracking how their borrowing costs might change from year to year can monitor these Treasury auction results online every May to anticipate rate adjustments before official award letters arrive.

Fixed Add-On Margins by Loan Type

To determine the final interest rate, the government adds a federally mandated margin, or add-on, to the 10-year Treasury auction yield. This margin varies depending on the type of loan and the borrower's academic level.

Under the federal guidelines outlined at https://fsapartners.ed.gov/knowledge-center/library/electronic-announcements/2026-06-04/interest-rates-federal-direct-loans-first-disbursed-between-july-1-2026-and-june-30-2027, the fixed add-on margins are structured as follows:

• Undergraduate Direct Subsidized and Unsubsidized Loans: An add-on of 2.05 percentage points. Adding 2.05% to the 4.468% Treasury yield results in the final 6.52% rate for the 2026–27 year.
• Graduate Direct Unsubsidized Loans: An add-on of 3.60 percentage points. Adding 3.60% to the 4.468% Treasury yield results in the final 8.07% rate.
• Parent PLUS Loans: An add-on of 4.60 percentage points. Adding 4.60% to the 4.468% Treasury yield results in the final 9.07% rate.

When reviewing a financial aid offer, families can consult a college financial aid glossary to clarify these loan categories before signing a Master Promissory Note.

Statutory Interest Rate Caps

While interest rates fluctuate annually based on the Treasury auction, federal law protects borrowers from extreme market volatility by imposing maximum interest rate caps. No matter how high market interest rates rise, the rates for newly issued federal loans cannot exceed these statutory limits:

• Undergraduate Direct Loans (Subsidized and Unsubsidized): Capped at 8.25%.
• Graduate Direct Unsubsidized Loans: Capped at 9.50%.
• Parent PLUS Loans: Capped at 10.50%.

Because these rates change every July 1, a student who borrows money over four years will likely have four separate loans, each with its own fixed interest rate. To stay informed about these annual adjustments and learn how financial aid and student loans are changing over time, families should ask their campus financial aid office for a projected multi-year borrowing worksheet. This document helps estimate the blended interest rate of a student's total debt portfolio upon graduation.

The Difference Between Subsidized and Unsubsidized Federal Loans

Federal Direct Loans fall into two primary categories. The financial aid office determines which type a student receives based on the Free Application for Federal Student Aid (FAFSA). The distinction between these two options directly affects the long-term cost of borrowing.

In-School Interest Subsidies for Undergraduates

Direct Subsidized Loans are reserved for undergraduate students who demonstrate financial need on their FAFSA. The federal government pays the interest on these loans while the student is enrolled at least half-time. This subsidy also applies during the six-month grace period after leaving school and during authorized periods of loan deferment.

Because of this subsidy, the principal balance does not grow while the student is in class. If an undergraduate borrows $3,500 in their first year, the balance remains exactly $3,500 when repayment begins. Families can verify whether they qualify for this subsidy by checking the "Direct Subsidized" line on their official college financial aid offer letter.

When Unsubsidized Interest Begins to Accrue

Direct Unsubsidized Loans are available to both undergraduate and graduate students. Financial need is not a requirement to qualify for these loans. The critical difference is that interest begins to accumulate the moment the school receives the loan disbursement from the federal government.

The borrower is responsible for paying all interest that accumulates during school, grace periods, and deferment. If a student chooses not to pay this interest while enrolled, the unpaid interest accumulates. It will eventually be added to the principal balance when repayment begins. Students can contact their loan servicer to request quarterly interest statements and pay the interest as it accrues to prevent the balance from growing.

Annual and Aggregate Borrowing Limits

The federal government limits how much a student can borrow each year. These limits depend on the student's dependency status and academic year.

According to studentaid.gov, dependent undergraduates can borrow up to $5,500 in their first year, with a maximum of $3,500 in subsidized loans. Second-year students can borrow up to $6,500, with a subsidized limit of $4,500. Students in their third year and beyond can borrow up to $7,500 annually, with a subsidized limit of $5,500. Over four years, a dependent undergraduate can borrow at most $27,000. The aggregate limit for dependent undergraduates is $31,000, of which no more than $23,000 may be subsidized.

Independent undergraduates have higher limits. They can borrow up to $9,500 in their first year, $10,500 in their second year, and $12,500 in their third year and beyond. The aggregate limit for independent undergraduates is $57,500.

Graduate and professional students face different restrictions. For new borrowers starting July 1, 2026, graduate students may borrow up to $20,500 annually in Direct Unsubsidized Loans, up to a $100,000 aggregate limit. Professional students may borrow up to $50,000 annually, up to a $200,000 aggregate limit. Borrowers can read about these new graduate and professional loan limits to understand how these changes impact their funding options. Families can also explore other Financial Aid resources to compare these limits against their total cost of attendance.

How Interest Accrues and Capitalizes on Federal Loans

The Daily Interest Formula

Federal student loans do not charge interest in a single annual lump sum. Instead, interest accumulates every single day. The financial aid office or a loan servicer calculates this daily charge using a simple mathematical formula. You can find this formula on your master promissory note or on studentaid.gov.

To calculate your daily interest charge, multiply your current principal balance by the interest rate. Then, divide that number by 365. For example, if a student has a $5,500 Direct Unsubsidized Loan for their first year of undergraduate study at the 2026–27 rate of 6.52% (as sourced from fsapartners.ed.gov), the daily interest calculation looks like this:

This loan accumulates approximately 98 cents of interest every day. For unsubsidized loans, this daily accumulation starts the moment the federal government disburses the funds to the college. This is true even while the student is enrolled full-time. If you want to verify the exact daily rate on your account, log into your federal student aid portal and look at the "daily interest factor" listed on your disclosure statement.

What is Interest Capitalization?

Interest capitalization is the process where unpaid, accrued interest is added directly to the principal balance of your loan. When this happens, your principal balance increases. Future interest is then calculated based on this new, larger amount. You are essentially paying interest on your interest.

According to studentaid.gov, capitalization typically occurs when your grace period ends and you enter active repayment. It also happens if you leave a deferment or forbearance period, or if you change certain repayment plans. For graduate students adjusting to the news that Grad PLUS loans are ending for new borrowers, managing capitalization on Direct Unsubsidized Loans is critical to keeping post-graduation balances under control. Capitalization permanently increases the lifetime cost of your debt because it resets the baseline for all future daily interest calculations.

How to Prevent Capitalization During School

Borrowers can prevent capitalization by making interest-only payments while they are still in school. When you receive your quarterly interest statements from your federal loan servicer, you have the option to pay off the accumulated interest before it capitalizes.

Families filling out the FAFSA should remember that aid packages are based on financial need, as detailed in our guide on FAFSA Income Limits: Why There Is No Cutoff and What Changes Your Aid. However, even if you only qualify for unsubsidized loans, you can control the final cost.

To take action, contact your assigned federal loan servicer. Ask them for a "voluntary interest payment" schedule. You can set up automatic monthly payments of just the interest amount. Paying off that 98 cents a day during college prevents that interest from ever compounding. This simple step ensures your principal balance remains exactly what you borrowed when repayment officially begins.

Comparing College Costs, Borrowing Needs, and Graduate Earnings

Net Prices Across Higher Education Sectors

A student must look beyond published sticker prices to understand their actual borrowing needs. The financial aid office calculates a student's net price by subtracting grants and scholarships from the total cost of attendance. As shown in the table below, these net costs vary dramatically by institutional sector.

According to CollegesRef data from the College Scorecard, public colleges carry a median average net price of $10,437, while private nonprofit colleges rise to a median of $27,167. Private for-profit institutions present the highest median net price at $30,181. For example, a family looking at Southern New Hampshire University will find an average net price of $36,764, according to CollegesRef data. To cover these net prices, families often turn to federal loans after submitting the Free Application for Federal Student Aid. Parents can prepare for this process by reviewing How to Fill Out the FAFSA as a Parent: Each Section, Step by Step.

Balancing Debt with Expected Post-Graduation Salary

Borrowing for college requires a careful comparison of student loan payments against realistic future income. A standard rule of thumb is to keep total student debt below the expected first-year salary after graduation.

The table below highlights the relationship between institutional sectors, graduation rates, and median earnings ten years after entering college. While private nonprofit colleges have a high median graduation rate of 70% and median earnings of $69,656, public colleges offer a median salary of $49,461 with a lower median net price. Families should request the specific program-level earnings data from a college's financial aid office for their intended major. This allows an applicant to calculate their projected monthly debt-to-income ratio before signing a Master Promissory Note. Understanding these metrics helps students evaluate college ROI and payback period to ensure their monthly loan payments remain manageable.

Using the CollegesRef College Cost Estimator

Families can simplify these calculations by using the CollegesRef College Cost Estimator. This free tool sets a college's published tuition beside its average net price, multiplies the year by four, and shows median graduate earnings, all from College Scorecard data, with no account required.

To use the tool, search for any of the 1,408 published U.S. colleges on CollegesRef with at least 2,000 students. The tool displays the school's actual historical net price alongside the median salary of its graduates. A student can compare these figures to determine if the debt required to attend a specific school aligns with the typical earnings of its alumni. This comparison is critical because federal undergraduate borrowing is capped. Dependent students can borrow a maximum of $27,000 over four years, according to studentaid.gov. Any funding gap beyond this limit must be covered by savings, work, or higher-cost parent loans.

Sector	Colleges	Median net price	Median in-state tuition	Median out-of-state tuition	Median graduation rate	Median earnings (10 yrs)
Public	1,041	$10,437	$6,034	$12,715	38%	$49,461
Private nonprofit	323	$27,167	$48,723	$48,702	70%	$69,656
Private for-profit	44	$30,181	$18,367	$18,367	41%	$47,524

Federal Student Loans Versus Private Student Loans

Fixed Rates and Federal Consumer Protections

Federal student loans carry fixed interest rates that remain identical for every borrower of the same loan type, regardless of credit history. A dependent undergraduate borrowing a Direct Subsidized Loan for the 2026–27 academic year receives a 6.52% interest rate, as documented by fsapartners.ed.gov. This rate is locked for the life of the loan.

These federal options come with statutory consumer protections that private lenders do not offer. If a graduate struggles to find work, they can access income-driven repayment plans, such as the Saving on a Valuable Education plan, which caps monthly payments based on discretionary income. Federal loans also provide access to deferment, forbearance, and forgiveness programs, including Public Service Loan Forgiveness. To access these federal protections, families must first complete the Free Application for Federal Student Aid, keeping in mind the specific priority dates listed in the FAFSA State Deadlines for 2027–28: Priority Dates That Matter.

How Private Loan Rates and Terms Differ

Private student loans are issued by commercial banks, credit unions, and state-based agencies. Unlike federal loans, private loans are priced based on underwriting criteria, meaning the interest rate depends on the credit score and debt-to-income ratio of the applicant or their co-signer. Most undergraduate applicants lack the credit history to qualify alone and must apply with a co-signer who agrees to take equal responsibility for the debt.

Private lenders offer both fixed and variable interest rates. Variable rates can change monthly or quarterly based on market indexes, which makes future monthly payments unpredictable. Furthermore, private loans lack federal safety nets. If a borrower experiences economic hardship, private lenders are not required to offer income-driven repayment, and loan discharge due to permanent disability or death is subject to individual lender policies rather than federal law.

Evaluating Which Option Fits Your Family Budget

Families must calculate their total funding gap before looking at private financing. First, subtract all grants and scholarships from the school's cost of attendance. Next, exhaust the maximum federal student loan limits, which are capped at $5,500 for first-year dependent undergraduates according to studentaid.gov.

To determine if a private loan is necessary, request a sample amortization schedule from the private lender before signing the promissory note. Look specifically at the "Total of Payments" line on the Truth in Lending disclosure form. Compare this total cost against the federal repayment terms. If you must use private loans, ask the financial aid office if they maintain a preferred lender list, which often details lenders that have passed school evaluations for customer service and lower fees. Families can also calculate how much college will really cost over four years to ensure they do not borrow more than their expected post-graduation starting salary.

Hypothetical Scenarios: Calculating the True Cost of 2026–27 Federal Loans

A dependent undergraduate borrowing the maximum first-year limit

This scenario uses hypothetical household figures to show how interest accumulates on a first-year undergraduate loan. A dependent student enrolls in a public university and accepts the maximum first-year Direct Loan limit of $5,500, as documented on https://studentaid.gov/understand-aid/types/loans/subsidized-unsubsidized. The financial aid office awards $3,500 in a Direct Subsidized Loan and $2,000 in a Direct Unsubsidized Loan. According to https://fsapartners.ed.gov/knowledge-center/library/electronic-announcements/2026-06-04/interest-rates-federal-direct-loans-first-disbursed-between-july-1-2026-and-june-30-2027, both loans carry a fixed interest rate of 6.52% for the 2026–27 academic year.

To calculate the cost of borrowing during school, the student tracks the interest accrual over 12 months. The federal government pays the interest on the $3,500 subsidized portion while the student is enrolled at least half-time. The $2,000 unsubsidized portion accrues interest immediately. To find the daily interest rate, the student divides the annual rate of 6.52% by 365 days, which equals 0.01786% per day. Multiplying this daily rate by the $2,000 principal yields a daily interest charge of approximately $0.36. Over one full year, this unsubsidized loan accrues interest that the student can calculate by multiplying the principal by the 6.52% annual rate.

The student decides to pay the accrued interest out of pocket before graduation. By making regular interest payments, the student prevents the interest from capitalizing and adding to the principal balance. This choice ensures that the repayment period begins with the principal still at exactly $2,000, saving money on compounding interest over the standard ten-year repayment term.

A parent balancing a funding gap with Parent PLUS loans

This scenario uses hypothetical household figures to evaluate the cost of a parent borrowing to cover an in-state funding gap. A family sends their child to The Pennsylvania State University-Main Campus, which has a CollegesRef verified average net price of $24,012. The student receives a maximum first-year student loan of $5,500, leaving a remaining balance of $18,512. The parent decides to cover this entire remaining balance using a federal Parent PLUS loan.

According to https://fsapartners.ed.gov/knowledge-center/library/electronic-announcements/2026-06-04/interest-rates-federal-direct-loans-first-disbursed-between-july-1-2026-and-june-30-2027, the fixed interest rate for a Parent PLUS loan disbursed for the 2026–27 year is 9.07%. This loan amount is within the Parent PLUS annual borrowing limit of $20,000 per year, as stated on https://studentaid.gov/understand-aid/types/loans/plus/parent. To calculate the annual cost, the parent multiplies the $18,512 loan principal by the 9.07% interest rate to find the amount of interest accruing in the first year alone.

The parent decides not to defer payments while the student is in school. By choosing to make immediate monthly payments that cover both the accruing interest and a portion of the principal, the parent prevents the interest from capitalizing. This decision prevents the loan balance from ballooning by the time the student graduates, keeping the overall cost of the loan manageable.

An independent student funding an associate degree

This scenario uses hypothetical household figures to analyze the borrowing path of an independent adult student. The student enrolls in a public associate degree program with an annual net price of $10,437, which matches the CollegesRef median net price for public colleges. As an independent undergraduate, the student is eligible to borrow up to $9,500 for their first year, according to https://studentaid.gov/understand-aid/types/loans/subsidized-unsubsidized. The student borrows the full $9,500, consisting of $3,500 in a subsidized loan and $6,000 in an unsubsidized loan.

The student calculates the interest on the $6,000 unsubsidized portion at the 2026–27 undergraduate rate of 6.52%. The annual interest on this portion is calculated by multiplying the $6,000 principal by the 6.52% rate. Over a two-year program, the accrued interest on the first-year unsubsidized loan accumulates based on this annual rate.

The student decides to let the interest capitalize upon graduation because they cannot afford payments while studying. This capitalization increases the starting repayment principal of the first loan by adding the accrued interest to the original $6,000. The student accepts this higher cost because the median earnings for public college graduates reach $49,461 ten years after entry, providing a stable path to manage the larger monthly payment.

Families can repeat these calculation steps with their own target colleges by using the CollegesRef College Cost Estimator.
