Two versions, and the older one has no balance gate at all. 34 CFR 685.208(b)(3) covers borrowers who entered repayment before July 1, 2006. It imposes no minimum balance and sets the term by balance bands: under $10,000 is 12 years, then 15, 20 and 25 years at the $10,000, $20,000 and $40,000 breakpoints, and 30 years at $60,000 or more. Paragraph (b)(4) covers borrowers entering repayment on or after that date, applies the more-than-$30,000 test, and simply caps the term at 25 years with no bands.
The $30,000 figure is statutory and frozen. It comes from a 1998 amendment and has never been indexed, while the balances it is meant to sort have risen in nominal terms. That makes it a threshold more borrowers clear over time, which is the opposite of how most eligibility figures age, and it is worth knowing that it is "more than $30,000" rather than "at least": a borrower owing exactly $30,000 does not qualify.
The statute adds a minimum the regulation states differently, and the two agree. 20 USC 1087e(d)(1)(C) offers the extended plan "except that the borrower shall annually repay a minimum amount determined by the Secretary in accordance with section 1078(b)(1)(L)," and that provision sets the annual floor at $600, or the remaining balance if less, but never less than the interest due. Six hundred dollars a year is fifty dollars a month, which is exactly the monthly minimum the regulation imposes, so a reader who finds the statutory cross-reference has not found a second and larger requirement.
The "new borrower" test is a separate trap and it is not the test used elsewhere. 685.208(b)(4)(i) defines a new borrower here as "an individual who has no outstanding principal or interest balance on a Direct Loan as of October 7, 1998, or on the date the borrower obtains a Direct Loan on or after October 7, 1998." A borrower who still had a 1996 loan outstanding in 1998, and who has not since started clean, fails it permanently. The Income-Based Repayment and Pay As You Earn plans also use a phrase called "new borrower," at 34 CFR 685.209(b)(13), and those tests use different dates and different conditions. Reasoning across from one to another gives the wrong answer.
Public Service Loan Forgiveness and the extended plan pull in opposite directions. An extended payment is not on the named list of qualifying plans, so it can qualify only under the catch-all at 20 USC 1087e(m)(1)(A)(iii), which requires the monthly payment to be at least what would have been paid on the ten-year standard plan. Stretching a term to 25 years is the act of paying less than that amount, so in the ordinary case an extended payment earns no credit. A borrower whose extended payment happens to exceed the ten-year figure would qualify, but the arithmetic makes that rare.
The plan owns the term; graduated payments own the shape; one plan can have both. 685.208(b)(4)(i) permits the extended plan to be paid on "either a fixed annual or graduated repayment amount," so an extended plan with stepped payments is a normal configuration rather than a contradiction. The graduated repayment plan is the separate entry that carries the rules on how far a step may travel.
Two boundaries that apply to the whole legacy menu. 20 USC 1078(b)(9)(A) sets a five-year floor: no plan may require repayment in less than five years unless the borrower specifically asks for a shorter period in the six months before repayment begins. And the plan is offered only for Direct Loans made before July 1, 2026, with 20 USC 1087e(d)(6)(B) barring the Secretary from authorizing it for a newer loan. It is not part of the 2028 wind-down, which reaches the income-contingent authority rather than the fixed-payment plans: paragraph (d)(1) offers its income-contingent option only "before June 30, 2028" and puts no date on the extended option beside it. So what ends access is taking a new federal loan or consolidating rather than missing a date.
One drafting artifact worth knowing if you read the regulation yourself. Paragraph (b)(3)(i) directs the reader to "paragraph (b)(4)(iv) of this section" for its own term bands, but the bands for that version are at (b)(3)(iv). The cross-reference did not survive the 2026 renumbering, and secondary summaries have copied it.
