RAP vs IBR: which should you actually pick?
For most exiting SAVE borrowers this is the real decision — Standard is only for people who can comfortably pay the loan off. Here's how the two income-driven plans differ, and the five questions that decide it.
Last reviewed: August 2026 (corrected 8 Aug: IBR is not being eliminated)
The head-to-head
| RAP | IBR | |
|---|---|---|
| Payment formula | 1–10% of total AGI ÷ 12, − $50 per dependent | 10% of income above 150% of poverty line (15% if you first borrowed before July 2014) |
| Minimum payment | $10/mo — never $0 | Can be $0 with low income |
| Forgiveness | 30 years (360 payments) | 20 years new IBR / 25 years old IBR |
| Prior IDR payments count? | Yes — your IBR/SAVE-era qualifying months carry into RAP | Yes — but months paid under RAP never carry back into IBR |
| Balance growth | Impossible — unpaid interest waived, principal falls by at least min(payment, $50)/mo | Possible — unpaid interest accrues if payment < interest |
| PSLF eligible | Yes | Yes |
| Spouse income (filing separately) | Excluded | Excluded |
| Payment cap | None — 10% of AGI even at high income | Capped at your 10-year Standard payment |
Question 1: How close are you to a forgiveness finish line?
This is the biggest one. If you've already got 10–15 years of qualifying IDR payments behind you, IBR's 20/25-year clock could forgive your balance a decade sooner than RAP's 30-year clock. A borrower with 13 years of credit picks IBR and is 7 years from forgiveness; on RAP they'd be 17 years out. Check your official payment count on StudentAid.gov — it's the single most valuable number in this decision.
Question 2: Is your payment lower on RAP or IBR?
Rules of thumb that fall out of the math:
- Low income, no dependents: IBR often wins on payment (can be $0; RAP's floor is $10 — trivial, but IBR's protected income means $0 until ~$24k AGI).
- Low-to-middle income with kids: RAP usually wins. The $50-per-dependent deduction is worth more than IBR's bigger poverty-line protection at many family sizes.
- Middle income, single: close race — run the numbers. At $55k AGI, RAP ≈ $229 vs new-IBR ≈ $259. At $75k, RAP ≈ $438 vs IBR ≈ $426. It flips around the bracket edges.
- High income: IBR's cap at the 10-year Standard payment protects you; RAP's 10% of total AGI does not. High earners rarely want either — Standard is usually cheaper overall.
Don't guess — the calculator does the exact bracket math in five seconds.
Question 3: Are you going for PSLF?
Both plans qualify. Strategy: pick whichever gives the lowest monthly payment, because after 120 qualifying payments the rest is forgiven tax-free — every dollar you didn't pay is a dollar forgiven. Your 20-vs-30-year timeline doesn't matter for PSLF; only the 10-year mark does.
Question 4: Would your balance grow on IBR?
If your IBR payment is below monthly interest (common at lower incomes with larger balances), your balance climbs on IBR while it would shrink on RAP — up to $600/year of guaranteed principal reduction from the match. If you might leave IDR someday (marriage, income jump, refinance), an IBR balance that grew for years is a real cost, not a paper one.
Question 5: The one-way door — this is the part most people miss
Switching plans is possible, but the payment counts don't travel in both directions, and that asymmetry deserves more weight than almost anything else on this page.
- IBR → RAP: your qualifying months come with you. Nothing is lost.
- RAP → IBR: the months you paid under RAP do not count toward IBR's 20- or 25-year clock. If you spend four years on RAP and then switch to IBR, you restart those four years from IBR's perspective.
So the two plans are not symmetric options you can freely toggle between. IBR is the reversible choice; RAP is the one that quietly costs you if you change your mind. If you're genuinely torn and all your loans predate July 1, 2026, starting on IBR preserves optionality that starting on RAP does not.
What actually ends in 2028 — and what doesn't
This is widely misreported, so to be precise: IBR is not being eliminated. Congress protected it. If all your Direct Loans predate July 1, 2026, you keep access to IBR for the life of those loans, and you can move between IBR and RAP as your circumstances change.
What does end is the other legacy plans. ICR, PAYE and SAVE are eliminated by July 1, 2028, and PAYE additionally closes to new enrollment on July 1, 2027. Anyone still on one of those gets moved to RAP or IBR.
The one action that genuinely costs you IBR access is taking out a new Direct Loan on or after July 1, 2026 — new borrowing puts you on RAP. So if you're thinking about going back to school, understand what that does to your repayment options before you borrow.
None of which removes the real asymmetry: RAP months never count backward toward IBR's clock. That's the reason to think before parking on RAP, not an artificial deadline.
One caveat on IBR right now
You may still see claims that IBR forgiveness is paused. That was true in mid-2025, but discharges resumed in September 2025, and an October 2025 court-supervised agreement with the American Federation of Teachers locked the restart in place. Batches can lag, but your discharge is dated to the day you earned it, and payments made after your eligibility date are refunded.
The short version
- Lots of prior IDR years? → IBR, chase the earlier forgiveness.
- Parent with modest income? → RAP is probably cheaper monthly, and your balance shrinks.
- PSLF? → whichever is lower monthly. Just stay in a qualifying plan.
- High earner, no forgiveness play? → neither. Standard (or aggressive paydown) costs least.
- Do nothing? → you get auto-enrolled in Standard and your payment may triple. Don't do nothing.
- Genuinely torn? → IBR is the reversible one. IBR months carry into RAP, but RAP months never count backward toward IBR's clock.
