All payments minus the balance: 120 payments, the last in September 2036.
The payment is the fixed amount that repays the balance over the plan's term: M = B × r × (1 + r)^n ÷ ((1 + r)^n − 1), where B is the balance, r the annual rate ÷ 12 and n the number of months. Federal fixed plans set n: 10 years on the standard plan, 25 on the extended plan, and 10 to 25 years by balance on the tiered standard plan for borrowers with a loan made on or after July 1, 2026. Payments are at least $50 a month.
With the defaults, 35,000 at the 2026–27 undergraduate rate of 6.52% costs 397.77 a month on the 10-year standard plan, with 12,732.90 of interest. The tiered standard plan gives the same balance 15 years: 305.27 a month but 19,949.05 of interest. Adding 100 a month to the 10-year plan ends it 31 months early and saves 3,516.78.
Income-driven plans (the Repayment Assistance Plan and IBR) are left out because their payments depend on income and family size; Federal Student Aid's Loan Simulator covers them.

Fixed monthly payments that repay the loan in 10 years, at least $50 a month, for borrowers whose federal loans were all made before July 1, 2026 (34 CFR 685.208(b)(1)). A 35,000 balance at 6.52% costs 397.77 a month and 12,732.90 of interest.
Borrowers with a federal loan made on or after July 1, 2026 get a term set by their total Direct Loan balance when repayment starts: under 25,000, 10 years; 25,000 to under 50,000, 15 years; 50,000 to under 100,000, 20 years; 100,000 or more, 25 years (Public Law 119-21, 34 CFR 685.208(c)). A 60,000 balance at 8.07% gets 20 years: 504.48 a month and 61,075.46 of interest.
Borrowers with more than 30,000 in Direct Loans and no federal loan made on or after July 1, 2026 can stretch repayment to 25 years with fixed or graduated payments (34 CFR 685.208(b)(4)). It lowers the payment but nearly triples the interest: 45,000 at 8.07% costs 349.41 a month and 59,821.98 of interest over 25 years, against 547.64 and 20,716.81 over 10 years.
6.52% for undergraduate Direct Subsidized and Unsubsidized Loans, 8.07% for graduate and professional Unsubsidized Loans and 9.07% for PLUS Loans first disbursed from July 1, 2026 to June 30, 2027 (Federal Student Aid). Each is the 4.47% high yield of the May 12, 2026 10-year Treasury auction plus a set margin, and stays fixed for the life of the loan (20 U.S.C. 1087e(b)(8)).
Yes, with no penalty: a borrower may prepay all or part of a Direct Loan at any time (34 CFR 685.211(a)(2)). On 35,000 at 6.52% over 10 years, 100 extra a month saves 3,516.78 and 31 months; 200 extra saves 5,490.71 and 49 months. An extra amount of at least one full payment counts as paying ahead and delays your next due date unless you tell the servicer otherwise.
