Federal Direct Loan Rates for 2026-27
For Direct Loans first disbursed from July 1, 2026 through June 30, 2027, the fixed rate is 6.52% for undergraduate Direct Subsidized and Unsubsidized Loans, 8.07% for graduate and professional Direct Unsubsidized Loans, and 9.07% for Parent PLUS and Grad PLUS Loans. Those rates apply to new loans in that disbursement window. An existing federal loan keeps the fixed rate assigned when it was disbursed, so enter the rate shown by your servicer when modeling an existing balance.
Four Payment Models, Not Four Eligibility Decisions
Run $42,000 at 6.52% through the payment models and the spread is substantial. Standard repayment at 10 years costs about $477 per month and $15,279 in total interest. Extended repayment over 25 years lowers the modeled payment to about $284 but increases total interest to roughly $43,234. Graduated repayment starts lower and rises every two years. The PAYE/new-borrower IBR option is different: it estimates a payment from AGI under a deliberately limited set of assumptions and does not decide whether you qualify.
Payment math is only one part of the choice. Loan type and disbursement dates determine which federal plans are available, while future income, family size, public-service work, and interest benefits can change the long-run cost. Use this page to explore arithmetic, then verify the available plan and official projection through StudentAid.gov.
What the PAYE/New-Borrower IBR Estimate Does
For a one-person household in the 48 contiguous states and D.C., the 2026 HHS poverty guideline is $15,960. PAYE and new-borrower IBR protect 150% of that amount, or $23,940, before applying 10%. With $54,000 of annual AGI, the modeled discretionary income is $30,060 and the estimated payment is $250.50 per month. The estimate is capped at a proxy 10-year Standard payment calculated from the balance and rate entered here.
This is not a universal IDR formula. It does not model RAP, older-borrower IBR at 15%, ICR, a larger household, Alaska or Hawaii guidelines, spouse income or debt, changing AGI, plan-specific interest treatment, or existing qualifying-payment credit. The projected balance at month 240 is therefore an illustration, not a promise that the amount will be forgiven. The official Loan Simulator uses more borrower and loan details to show current options.
Extra Payments: Small Amounts, Outsized Impact
Adding $150 per month to a standard 10-year payment on $42,000 at 6.52% cuts the modeled payoff from 120 months to 84 months and saves $4,928 in interest. That is about a 32% reduction in total interest. The leverage is even higher on longer terms: $150 extra on the 25-year extended model cuts payoff by 13.5 years and saves about $25,479 in interest.
Direct extra payments to the highest-rate loan first. Federal loan payments are generally applied to outstanding interest before principal; once accrued interest is covered, an amount above the required payment reduces principal. If you have multiple loans, use your servicer's payment directions to target the specific loan or loan group you want to reduce. Unsubsidized loans often deserve priority because interest generally accrues during more periods.
Refinancing: When the Rate Spread Justifies the Tradeoff
A lower quoted rate does not by itself prove that private refinancing is better. Compare the new APR, fees, term, monthly payment, and total repayment with the existing loans. An illustrative $42,000 balance refinanced from 6.52% to 4.25% over the same 10-year term lowers the modeled payment from about $477 to $430 and total interest from about $15,279 to $9,629, but an actual offer and any change in term will produce different results.
Refinancing a federal loan with a private lender is generally irreversible and can remove access to federal repayment, forgiveness, discharge, deferment, and forbearance provisions. Review the current federal program rules and the private contract before proceeding. The calculator can compare payment math, but it cannot assign a dollar value to protections you may later need.
Interest Capitalization: The Silent Balance Inflator
Interest can continue accruing during deferment or forbearance, and unpaid interest may be capitalized in situations allowed by the loan terms. On a $42,000 unsubsidized loan at 6.52%, one year with no payments accrues about $2,738 under this simple annual illustration. If that amount capitalizes, principal becomes about $44,738. Amortizing that larger balance for a new 10-year period at the same rate adds roughly $996 in interest beyond the interest already added to principal. Your servicer can confirm whether and when capitalization applies to your loan.
Paying interest during deferment or forbearance - even if you can't make full payments - prevents capitalization. Even $100/month toward interest during a 12-month forbearance reduces the capitalization hit by roughly 42%. If full interest coverage isn't possible, any amount helps reduce the compounding effect.
