How RAP Actually Works: Brackets, Credits, and the Fine Print

The Repayment Assistance Plan (RAP) launched July 1, 2026 as the replacement for SAVE and, for anyone borrowing after that date, the only income-driven option that will ever exist for those loans. Most articles describe it in a sentence — "payments of 1–10% of income." That sentence hides four rules that decide whether RAP is a good deal for you. This guide covers all of them, with citations to the final regulations (34 CFR 685.209, as rewritten May 1, 2026).

Rule 1: The brackets are cliffs, not tax brackets

Your annual RAP payment is a single percentage applied to your entire adjusted gross income. Earn $10,000 or less and you pay a flat $120 a year. Above that, the rate starts at 1% and climbs one point per $10,000 of AGI, topping out at 10% above $100,000.

Unlike income tax, these are not marginal rates. At $50,000 AGI you pay 4% of all $50,000 — $166.67/month. At $50,001 you pay 5% of all $50,001 — $208.34/month. That one dollar of extra income costs you $41.67 every month, about $500 a year. At the $100,000 line the jump is $83/month. If your income sits just under a boundary, a small raise, a bonus, or even interest income can genuinely leave you worse off. Our calculator warns you automatically when you're within $3,000 of a cliff.

Rule 2: $50 per dependent, then a $10 floor

From your monthly base payment, subtract $50 for every dependent claimed on your federal tax return (the IRS §152 definition — children and qualifying relatives both count). The floor comes after: no matter how many dependents, the payment never goes below $10/month. A borrower earning $48,000 with three dependents pays $10 — not $10 with three dependents "wasted," since the third credit only partially applies. And there is no $0 payment on RAP at any income, ever. Full details in our dependent credit guide.

Rule 3: Your balance can never grow

RAP's genuinely excellent feature: every month you pay on time, any interest your payment didn't cover is simply not charged (685.209(h)(4)). Not deferred, not capitalized — gone. The negative-amortization spiral that haunted older plans can't happen here.

On top of that sits a principal subsidy most sites misreport. If your payment reduces principal by less than $50 in a month, the government tops up the difference — but the top-up is capped at the lesser of $50 or your payment (685.209(o)(2)). Someone paying $300 where $280 goes to interest gets a $30 match (total principal reduction: $50). But someone paying the $10 minimum gets a $10 match, not $50. Claims that every RAP borrower's balance "drops at least $50 a month" are wrong at exactly the incomes where it would matter most.

One trap: both subsidies require an on-time payment of the amount due. If you pay extra and your servicer advances your due date ("paid-ahead status"), months with no amount due earn no waiver and no match. If you plan to prepay, tell your servicer not to advance your due date.

Rule 4: Forgiveness at 30 years — with a one-way door

RAP forgives whatever remains after 360 qualifying monthly payments. Months you already spent on IBR, PAYE, SAVE, or ICR count toward that 360, and so do certain deferment months (unemployment and economic hardship among them). But the credit only flows one direction: months paid on RAP never count toward IBR's 20- or 25-year forgiveness. Try RAP for five years, switch to IBR, and those five years vanish from the IBR clock. If your strategy leans on IBR forgiveness, treat enrolling in RAP as a door that locks behind you. (PSLF is unaffected: RAP is a qualifying plan, 120 payments, still federally tax-free.)

Also know that forgiveness in 2026 and later is federally taxable for non-PSLF discharges — the exclusion expired December 31, 2025. RAP's first regular forgiveness won't occur until the 2050s, but the tax treatment then is anyone's guess; our tax bomb guide covers the current rules.

Who can and can't use RAP

• Eligible: Direct subsidized/unsubsidized loans, grad PLUS loans, most Direct consolidation loans — including defaulted loans, and loans from any era.
• Never eligible: parent PLUS loans and any consolidation loan that repaid one. Those are permanently locked out of RAP (and after July 2026, largely out of income-driven repayment entirely).
• New borrowers (first loan after July 1, 2026): RAP or the Tiered Standard plan are the only choices — IBR, PAYE, and ICR are closed to those loans.
• Married filing separately: only your own AGI counts — see the married-filing-separately guide, because an early draft of the law said otherwise and the misinformation is everywhere.

The bottom line

RAP is the cheapest monthly payment most middle-income borrowers will be offered, and the no-growth balance guarantee has real psychological and financial value. But a low payment held for 30 years is often the most expensive path in total dollars — in our five worked examples, RAP wins some and loses others by five-figure margins.
