The Repayment Assistance Plan against IBR, assessed
A new federal plan promises a balance that never grows. Assessed on the published regulation: how each plan sets a payment, what happens to unpaid interest, and what thirty years of payments costs against twenty.
The Repayment Assistance Plan is the first income-driven federal plan built around a promise about the balance rather than the payment. The Department of Education’s framing, in the RISE final rule, is that it lets borrowers “actually pay down their student loan debt by preventing negative amortization over the life of the loan”.
That is a testable claim, and the regulation is public. The rule takes effect on 1 July 2026 and the plan’s terms sit in 34 CFR 685.209, against which we compare Income-Based Repayment below.
How each plan sets the payment
IBR takes a percentage of income above a threshold: 15 per cent of adjusted gross income exceeding 150 per cent of the poverty guideline, or 10 per cent for a new borrower, capped at the ten-year standard payment.
RAP takes a percentage of AGI from the first dollar, on a published ladder, with no poverty-line shelter and no cap. The ladder is regular — $120 a year at the bottom, then a percentage point per $10,000 band.
The monthly payment is that base divided by twelve, less $50 per dependent, with a $10 floor except on the final payment. Note the counting unit: RAP works on dependents, IBR on family size.
Does the no-growth promise hold up?
On the regulation’s terms, yes — though not by the mechanism most readers assume.
Two provisions do the work. The Secretary does not charge the account for accrued interest an on-time payment fails to cover. And where an on-time payment reduces principal by less than $50, a matching payment tops that reduction up to the lesser of $50 or the payment made.
Case B is the striking one. A borrower paying $50 against a loan accruing $216.67 still sees the balance fall $50, because the shortfall is not charged and the match applies anyway. Under IBR, unpaid interest is waived only on subsidized loans, and only for three years.
So the claim is real. It is not a claim about total cost.
The thirty-year problem
RAP forgives the remaining balance after 360 qualifying payments over at least 30 years. IBR forgives after 240 payments and 20 years for a new borrower, or 300 and 25 years for one who is not.
That is five to ten additional years of payments, and it is the price of the subsidy. A balance that never grows is not a balance that costs less: for someone who would have reached IBR forgiveness with a large sum outstanding, the longer road can be dearer even with the waiver running.
Two features that catch people out
The bands are cliffs, not marginal rates. The percentage applies to the whole of AGI, so it steps rather than tapers. AGI of $60,000 gives a base of $3,000, or $250 a month; $60,001 crosses into the 6 per cent band and gives $3,600.06, about $300. One dollar adds roughly $600 a year.
Overpaying can switch the subsidy off. This should worry our readers most, because overpaying is the instinct we normally encourage. An excess payment automatically advances the next due date, and no matching principal payment is available for periods without a due date; where a payment is credited forward, accrued interest can be charged. To keep the subsidy, the borrower must opt out of advancing the date, every time.
Eligibility, and a narrowing menu
RAP covers Direct Subsidized and Unsubsidized Loans, Direct PLUS Loans to graduate or professional students, and Direct Consolidation Loans that are not excepted consolidation loans. Parent PLUS sits outside it. The same rulemaking phases out ICR, PAYE and SAVE, which is why this comparison matters at all.
Pros and cons
Verdict
Our assessment is that RAP is better designed than its predecessors and a worse deal than its framing suggests, and that both can be true at once. The transparency is real; the flexibility sits in the wrong place, generous to someone whose income stays low for three decades and awkward for someone whose circumstances improve and who wants the balance gone. The same trade sits underneath hardship arrangements generally: relief now, priced later.
