IBR vs. RAP: The Case for Locking In Your Repayment Track After SAVE Ended

The SAVE Plan is gone. On March 10, 2026, a federal court officially vacated it following a settlement between the Trump administration and the State of Missouri. The Department of Education then began notifying all 7.5 million borrowers who were still enrolled that they needed to move to a different repayment plan — with roughly 90 days from July 1, 2026 to make the switch.

For context: more than 8 million borrowers joined SAVE during its lifetime. About 7.5 million were still active when the court order came through in March 2026.

Most borrowers are focused on the next bill. What they haven't fully reckoned with is that this decision could shape what they pay over the next two or three decades — and whether they can ever get back to a better option if their life changes.

The two plans at the center of this choice are Income-Based Repayment (IBR) and the brand-new Repayment Assistance Plan (RAP). This article explains how each one works, which borrower profiles each tends to suit, and what the real tradeoffs look like — illustrated through four physician scenarios. It cannot tell you which plan is right for you. That depends on details only you and your servicer can assess.

What Just Happened — and Why It Matters

The SAVE Plan launched in 2023 as the Biden administration's most generous income-driven repayment option. Payments could drop to $0, forgiveness timelines were shorter than anything before, and interest subsidies were broad. More than 8 million borrowers signed up.

Then Republican state attorneys general sued, arguing the administration had overstepped its legal authority. Courts agreed. By August 2025, interest was accruing again on loans that had been frozen in SAVE forbearance. The Trump administration settled with Missouri in December 2025, and the court finalized that on March 10, 2026.

SAVE was ended through two separate processes that landed at the same place: the federal court vacated the plan's authorizing regulation in March 2026, and the One Big Beautiful Bill Act (OBBBA) included a statutory termination provision effective July 2028. Both are now done.

The OBBBA, signed into law on July 4, 2025, also cleared the deck for what came next. It terminated SAVE, PAYE, and ICR, and created a new plan — RAP — launching July 1, 2026. IBR survived, but with real restrictions on who can still get in.

The new repayment landscape:

Understanding IBR: The Legacy Plan That Survived

IBR has been around since 2009. It's the only income-driven plan from the old system that Congress decided to keep permanently — which says something about how it's held up.

Your monthly payment under IBR is based on your discretionary income — your adjusted gross income (AGI) minus 150% of the federal poverty guideline (FPL) for your family size. If you have dependents or a modest income, that formula protects a larger share of your earnings, which keeps payments lower.

Two versions of IBR — which one applies to you:

• Old IBR — Loans before July 1, 2014: payments are 15% of discretionary income, with forgiveness after 25 years.
• New IBR — Loans on or after July 1, 2014: payments are 10% of discretionary income, with forgiveness after 20 years.

Both versions cap your monthly payment at whatever you'd owe under the standard 10-year plan. That ceiling matters most when income rises — it stops your payment from climbing without limit.

One significant change from the OBBBA: the old "partial financial hardship" requirement is gone. You used to have to prove your income-driven payment was lower than your standard one to qualify. That test no longer applies. Any borrower with eligible loans can now enroll.

Understanding RAP: The New Default

RAP is the Trump administration's replacement for SAVE. It launches July 1, 2026. For anyone taking out their first federal loan after that date, it's the only income-driven option available.

RAP calculates your payment differently from IBR. Rather than using discretionary income, it takes a percentage directly from your AGI — no poverty guideline deduction. The percentage ranges from 1% to 10% depending on your income bracket. The minimum payment is $10 per month for those earning under $10,000 a year, which removes the $0 floor that existed under IBR and SAVE.

RAP's two built-in borrower protections:

1. Interest subsidy — Under RAP's statutory interest waiver provision (P.L. 119-21), unpaid interest that exceeds your monthly payment is forgiven by the government rather than rolled into your balance. Your principal is designed to stay flat, not grow. The mechanics of this provision are subject to DoE implementing regulations and servicer processing — verify the specific terms with your servicer when you enroll.
2. Principal match — Under P.L. 119-21, RAP includes a provision designed to ensure your loan principal decreases by at least $50 per month, with the government covering the difference if your payment wouldn't achieve that minimum on its own. This provision is also subject to DoE regulations and servicer processing. Confirm how it applies to your specific account.

Forgiveness under RAP comes after 30 years — ten years longer than New IBR.

RAP does qualify for Public Service Loan Forgiveness (PSLF), and payments count toward the 120 required for tax-free forgiveness. For borrowers who aren't pursuing PSLF, though, that 30-year timeline is a meaningful disadvantage.

IBR vs. RAP: The Key Differences Side by Side

† Most graduate and professional degree holders have only Direct Unsubsidized Loans and receive no IBR interest subsidy at all. The 3-year benefit applies only to subsidized loan interest. For borrowers with an all-unsubsidized portfolio, RAP's full interest waiver offers a bigger advantage than this row suggests.

Who RAP Tends to Favor

Looking at published plan mechanics and 2026 federal poverty guidelines, RAP generally produces lower monthly payments for borrowers earning under about $80,000 per year with few or no dependents. The tiered bracket structure, combined with the $50 per-dependent monthly deduction, brings payments down for some lower-income households. Whether it does for you depends on your specific numbers.

For borrowers who watched their balances grow during SAVE forbearance — when interest kept accruing even while payments were frozen — RAP's interest subsidy is designed to prevent that from happening again. Your balance should stay flat while you remain enrolled and current on payments. Confirm how your servicer implements this.

RAP is also the only income-driven option for anyone who borrows after July 1, 2026. If you're in school now or starting a graduate program, RAP is the only IDR plan that covers those post-cutoff loans.

Who IBR Tends to Favor

IBR tends to produce lower payments once income rises above roughly $80,000–$90,000 per year. That's when IBR's payment cap kicks in — payments stop rising even as income does. RAP has no equivalent ceiling, so high earners on RAP can end up paying more per month than they would on a fixed standard plan.

The forgiveness timelines also matter. IBR forgives after 20 years; RAP takes 30. For borrowers on an IDR forgiveness path rather than PSLF, that extra decade of payments is a real cost — how much it matters depends on your income trajectory and remaining balance.

IBR also tends to favor borrowers with larger families. It subtracts 150% of the federal poverty guideline — scaled to your household size — before calculating your payment. The bigger your family, the higher the deduction and the lower your effective payment. Your actual results depend on your AGI, filing status, and family composition.

For PSLF borrowers, the question is simple: which plan produces the lower monthly payment? Both qualify for PSLF, so payment size is what matters. The Federal Student Aid Loan Simulator at studentaid.gov is a good place to start.

The Hidden Risk: Mixed-Loan Borrowers and the One-Loan Rule

There's one scenario that catches borrowers off guard, and it's worth spelling out.

If you have pre-July 2026 loans on IBR and you take out any new federal student loan after July 1, 2026 — including a Direct Consolidation Loan — all of your loans fall under the eligibility rules that apply to the new one. The new loan isn't eligible for IBR, and under current implementation, that affects your access to IBR across your entire portfolio.

This matters for graduate students in multi-year programs. It matters for anyone thinking about consolidation. And it matters for anyone who might go back to school.

The Forgiveness Tax Bomb — A New Reality for Both Plans

A temporary federal protection that made IDR loan forgiveness tax-free expired on December 31, 2025. From 2026 onward, any balance forgiven through an income-driven repayment plan — IBR or RAP — is counted as taxable income at the federal level.

PSLF is different. Forgiveness under Public Service Loan Forgiveness is currently excluded from gross income under IRC §108(f)(1). That exclusion has no sunset date, and no legislation to change it is pending as of this writing. Even so, Congress can always act. Borrowers nearing PSLF forgiveness should confirm the current tax treatment with a qualified tax professional.

For everyone else, the math shifts. If you're on track to have $60,000 forgiven at the end of a 20-year IBR plan, that $60,000 is taxable income in the year it's forgiven. At a 22% federal rate, that's roughly $13,200 in federal taxes — before state tax. Borrowers in California (top marginal rate 9.3%) or New York could face combined bills exceeding $18,000–$21,000 on the same forgiven amount. This future bill — often called the "tax bomb" — should be part of any long-term IDR plan. How big it gets depends on your income, filing status, state, and the size of the forgiven balance.

RAP carries the same tax exposure. The 30-year forgiveness timeline gives your balance more time to shrink — but it also means 10 more years of payments before you get there.

The July 1, 2028 Deadline: What the Timeline Looks Like

Key dates:

• Now through June 30, 2026 — Eligible borrowers can still enroll in PAYE, ICR, or IBR depending on their specific loan profile. SAVE is closed. Borrowers who have already identified their preferred plan may benefit from contacting their servicer early to reduce the risk of processing delays.
• July 1, 2026 — RAP launches. Loan servicers begin sending 90-day transition notices to SAVE borrowers.
• ~September 30, 2026 — The 90-day window closes for most SAVE borrowers. Those who haven't selected a plan by then will be administratively transitioned — typically to the Standard Repayment Plan under current DoE guidance, which carries fixed payments based on the full loan balance over 10 years and does not qualify for PSLF credit.
• July 1, 2028 — PAYE and ICR sunset under current statutory text. IBR closes to new enrollees. Borrowers still on PAYE or ICR who haven't transitioned are moved to the applicable available plan.

Four Illustrated Physician Scenarios

The four profiles below reflect real situations physicians face at different career stages — from first-year residency to mid-career attending practice. They are fictional composites, not real people. The payment figures are modeled approximations and will differ based on your actual circumstances. Verify your own numbers with your servicer and a licensed financial advisor before making any plan decision.

Illustrated Scenario 1 — Dr. Mark: The PGY-1 Resident at the Start of His PSLF Clock

SAVE forbearance note: Months in SAVE administrative forbearance (approximately July 2024 onward) did not count as qualifying PSLF payments. Borrowers who were in SAVE forbearance should verify their current official PSLF qualifying payment count directly with their servicer. The count above reflects the scenario as modeled.

The Question Being Analyzed

Mark is at the start of a decade-long PSLF track. He'll spend three to four years in residency and potentially two to three more in fellowship — all at a qualifying non-profit employer — before his first attending role. Every one of those months counts toward the 120 qualifying payments he needs. Since PSLF forgives whatever remains at payment 120, tax-free under current law, his entire $245,000 balance — plus any interest that accrues — gets wiped out without a tax bill. The only question right now is which plan keeps his monthly payment as low as possible during training.

A note on Mark's loan type: His $245,000 are Direct Unsubsidized Loans. IBR's partial interest subsidy — which waives accruing interest for the first three years — only applies to subsidized loans. On Mark's unsubsidized balance, interest keeps building under IBR throughout his training, so his balance will grow. Under RAP, the statutory interest waiver is designed to prevent that growth across all loan types while he stays enrolled and current. For a PSLF borrower, this matters less than it might seem — the full remaining balance, whatever it is at payment 120, is forgiven tax-free either way. But from a practical standpoint during training, RAP's balance protection is worth noting.

IBR Payment Calculation — 2026 Official FPL

2026 single-person FPL (48 states): $15,960

• 150% FPL deduction: $15,960 × 1.5 = $23,940
• Discretionary income: $52,000 − $23,940 = $28,060
• Monthly IBR payment (10% ÷ 12): $28,060 × 10% ÷ 12 = $234/month

Payment Comparison — Modeled

What the $17 gap means over 10 years of PSLF — Modeled

Note: The forgiven balance estimate accounts for interest accrual over 10 years at an approximate 7% average rate. Because Mark's loans are unsubsidized, IBR does not subsidize accruing interest, meaning his balance may grow throughout training. Under RAP's statutory interest waiver, the balance is designed to remain stable. For PSLF purposes, both scenarios result in full tax-free discharge at payment 120 — but the size of the forgiven amount will differ.

What this scenario shows

For a PSLF-track physician at the start of residency, RAP's lower monthly payment means roughly $2,040 less in total payments before forgiveness. Since PSLF forgiveness is tax-free under current law and arrives at payment 120 regardless of which IDR plan you're on, RAP's 30-year IDR timeline simply doesn't apply here.

The caveat that matters: this only holds if Mark completes 120 qualifying payments under a qualifying employer. A career change out of non-profit medicine, an employer disqualification, or a missed recertification after the 2028 IBR window closes would strand him on RAP's 30-year IDR track with no path back to IBR and no PSLF exit. Before choosing RAP, any physician should honestly assess how certain they are about staying in non-profit medicine for the full ten years.

Illustrated Scenario 2 — Dr. Esther: The PGY-5 Fellow with 44 Payments Already Banked

SAVE forbearance note: Months in SAVE administrative forbearance (approximately July 2024 onward) did not count as qualifying PSLF payments. Borrowers who were in SAVE forbearance should verify their current official PSLF qualifying payment count directly with their servicer before making plan decisions. The count above reflects the scenario as modeled.

The Question Being Analyzed

Esther is 44 payments into her PSLF track, with 76 to go. Her $310,000 balance — built up over seven years of medical school tuition and living expenses — will be forgiven tax-free at payment 120 regardless of which plan she's on. She has roughly two more years of fellowship ahead, followed by her first years as a pediatric cardiologist at a qualifying non-profit hospital.

Her family size is the deciding factor. IBR's family-size FPL deduction produces a dramatically lower payment than RAP's AGI-based formula at her household income level.

IBR Payment Calculation — 2026 Official FPL for Family of 4

2026 FPL for a family of 4 (48 states): $33,000

• 150% FPL deduction: $33,000 × 1.5 = $49,500
• Discretionary income: $85,000 − $49,500 = $35,500
• Monthly IBR payment (10% ÷ 12): $35,500 × 10% ÷ 12 = $296/month

Payment Comparison — Modeled

What that gap costs over 76 remaining PSLF payments — Modeled

Why family size drives the outcome here

IBR deducts 150% of the federal poverty guideline — scaled to family size — from income before it calculates your payment. A family of four gets a $49,500 deduction, leaving only $35,500 in discretionary income subject to the 10% rate. RAP takes a percentage directly from AGI and then subtracts $50 per dependent. At $85,000 with two children, RAP shields far less income from the calculation. Your actual results depend on your income, filing status, and the number of dependents on your most recent tax return or income certification.

What this scenario shows

In this scenario, IBR's monthly payment is roughly 37% lower than RAP's — or put the other way, RAP costs about 58% more per month for a borrower in this situation. Over Esther's 76 remaining PSLF payments, that adds up to approximately $12,996 more under RAP. Either way, her $310,000 balance gets forgiven tax-free at payment 120. But spending nearly $13,000 extra to reach the same outcome isn't a trade-off with any benefit.

Illustrated Scenario 3 — Dr. Peter: The Outbound Resident Racing to Lock In IBR Before Attending Salary Hits

The Question Being Analyzed

Peter's situation differs from Mark and Esther's in one key way: he's not pursuing PSLF. His employer is for-profit, which rules it out. His repayment strategy is either IDR-based forgiveness — 20 years under IBR or 30 under RAP — or paying down the balance directly once his attending income is high enough.

The decision he's making right now, at the gap between residency and attending practice, may be the most consequential financial plan choice of his career. His AGI this year is $35,000. Next year it will be around $250,000. IBR and RAP produce almost identical payments today. But at attending income, the gap is roughly $200 per month — and it only grows from there. If Peter doesn't lock in IBR before the July 1, 2028 window closes, that payment cap is gone for good.

IBR Payment Calculation — 2026 Official FPL (Transition Year)

2026 single-person FPL (48 states): $15,960

• 150% FPL deduction: $15,960 × 1.5 = $23,940
• Discretionary income: $35,000 − $23,940 = $11,060
• Monthly IBR payment (10% ÷ 12): $11,060 × 10% ÷ 12 = $92/month

IBR Payment Calculation — Attending Year (AGI $250,000)

• 150% FPL deduction: $15,960 × 1.5 = $23,940
• Discretionary income: $250,000 − $23,940 = $226,060
• Monthly IBR payment (10% ÷ 12): $226,060 × 10% ÷ 12 = $1,884/month

RAP Payment Calculation — Attending Year (AGI $250,000)

• RAP bracket above $100,000: 10% of AGI
• Monthly RAP payment: $250,000 × 10% ÷ 12 = $2,083/month

Payment Comparison — Transition Year vs. Attending Year — Modeled

Note: IBR's payment cap on a $180,000 loan balance at ~7% is approximately $2,090/month, reached at roughly $275,000 AGI. Above that income, IBR payments stop rising. RAP has no equivalent ceiling — payments continue scaling at 10% of AGI regardless of income.

Why the IBR payment cap is the core issue for Peter

IBR caps monthly payments at the 10-year Standard Plan amount, no matter how much income rises. For Peter's $180,000 balance at roughly 7%, that cap sits at about $2,090/month. Once his payment hits that ceiling — at around $275,000 AGI — it stays there regardless of what he earns.

RAP has no ceiling. At the 10% bracket that applies to incomes above $100,000, a $400,000 attending salary produces a modeled RAP payment of about $3,333/month — $1,243 more per month than IBR's capped figure, or roughly $14,900 more per year.

Right now, at a $35,000 transition-year AGI, the difference is just $5/month. This is the window. If Peter enrolls in IBR today, the cap is his permanently. If he waits past July 1, 2028 without enrolling, IBR closes and RAP — with no ceiling — becomes his only option as his income climbs.

What this scenario shows

Right now, IBR and RAP look almost identical for Peter. The real difference shows up next year and compounds from there. Enrolling in IBR while the payments are minimal and the window is still open locks in the cap before it matters most. Waiting — whether until the attending salary arrives or until after the 2028 deadline — gives up that protection permanently.

Illustrated Scenario 4 — Dr. Linda: The Mid-Career Attending Locked Out of IDR by Legacy FFEL Loans

The Question Being Analyzed

Linda went to medical school in the late 1990s and early 2000s, when the Federal Family Education Loan (FFEL) program was the standard way to borrow for graduate and professional school. FFEL loans were issued by commercial lenders — banks and credit unions — and backed by a federal guarantee. The Direct Loan program didn't take over the market until 2010.

That history matters. Linda holds $145,000 in commercial FFEL Graduate Stafford Loans. They're federally guaranteed, but privately held — and that distinction locks her out of every modern income-driven repayment plan. IBR, RAP, PAYE, ICR: all of them require federal Direct Loans. Her FFEL loans don't qualify. She can't enroll in IBR or RAP. She can't pursue PSLF. Right now, she's stuck on a fixed commercial repayment schedule.

At the standard 6.8% FFEL Graduate Stafford rate, the 10-year Standard Plan payment on $145,000 comes to roughly $1,670/month — a significant fixed obligation for a family medicine physician in private practice.

The fix is Direct Loan Consolidation. Converting her FFEL loans into a federal Direct Consolidation Loan before the June 30, 2026 deadline unlocks IBR access and could reduce her monthly payment considerably — based on her current AGI.

What the two analytical paths look like

Note: Unlike Parent PLUS borrowers — who must route through ICR before accessing IBR — FFEL Graduate Stafford Loans consolidate into a Direct Consolidation Loan that is eligible for IBR enrollment directly. The ICR-first requirement applies to Parent PLUS loans, not to FFEL Graduate Stafford debt. Linda's consolidation pathway is more direct, but the June 30, 2026 deadline is equally binding.

Why June 30, 2026 is the line

After July 1, 2026, a newly consolidated Direct Consolidation Loan is not eligible for IBR if the original loans included any post-July 2026 disbursements. Linda's FFEL loans were all issued well before that, so consolidating before the June 30, 2026 cutoff preserves her full access to IBR. Missing it closes that path permanently under the current statutory framework.

Without consolidation, the $1,670/month Standard Plan payment continues indefinitely.

If Linda consolidated in time, the next step is enrolling in IBR before July 1, 2028. If she hasn't yet consolidated, she should contact her servicer right away and speak with a licensed student loan attorney or financial advisor. This deadline can't be made up after the fact.

What to Consider Before Acting: A Framework, Not a Prescription

If you were on SAVE:

1. Log into studentaid.gov and confirm your loan details, current servicer, and any existing PSLF qualifying payment count.
2. If you've already identified your preferred plan, reaching out to your servicer before the 90-day notice window may reduce processing delays during the transition period.
3. Use the FSA Loan Simulator at studentaid.gov to model projected payments under both IBR and RAP using your actual income, family size, and loan details before deciding.
4. If you're on a PSLF track with pre-July 2026 loans and no planned future borrowing: compare modeled IBR and RAP payment amounts. The plan producing the lower monthly payment generally minimizes total out-of-pocket cost before forgiveness — but your specific career stability and employer qualification status both factor into that analysis.
5. If you're not pursuing PSLF and hold pre-July 2026 loans: IBR's 20-year forgiveness timeline and payment cap may represent a structural advantage over RAP's 30-year track, particularly if income growth is expected. Individual results depend on your actual income trajectory and loan balance.
6. Submit your application well before the 90-day window closes. Servicer processing times during transition periods can stretch longer than expected.

If you have Parent PLUS loans:

• Parent PLUS borrowers seeking income-driven repayment access should discuss the June 30, 2026 consolidation deadline with their servicer and assess whether consolidation makes sense for their specific loan situation. The eligibility rules are complex and fact-specific; a licensed student loan advisor can help assess your options.
• Under current law, at least one qualifying ICR payment is required before a consolidated Parent PLUS borrower can access IBR. Confirm the specific procedural steps with your servicer.

If you're considering new federal borrowing after July 2026:

• IBR is not available for post-July 2026 loan disbursements under current law.
• Under current statutory implementation, new federal borrowing after July 1, 2026, by a borrower currently on IBR may affect IBR eligibility across the entire loan portfolio. Confirm the specific implications with your servicer and, where appropriate, a licensed advisor before borrowing.

For all IDR plan holders:

• IDR forgiveness outside of PSLF is taxable under current federal law from 2026 onward. Working with a qualified tax professional to build a long-term reserve strategy is a reasonable step for borrowers not pursuing PSLF.
• Annual income recertification is required for all IDR plans. Missing a recertification deadline can result in administrative plan changes and potential interest consequences. Confirm your recertification schedule with your servicer.

The Bottom Line

SAVE was the most generous student loan repayment plan the federal government had ever offered. It's gone. The replacement offers less income protection, longer forgiveness timelines under RAP, and — for many borrowers — higher monthly payments than IBR.

The IBR versus RAP decision doesn't have one right answer. For eligible existing borrowers — those whose loans were all disbursed before July 1, 2026 and who don't plan to take new federal loans after that date — IBR's 20-year forgiveness track and payment cap may be the better structural fit, especially for higher earners, larger families, or those in private practice. For lower-income borrowers with few dependents who want protection against a growing balance, RAP's interest subsidy may produce a better outcome. For anyone whose first federal loan is disbursed on or after July 1, 2026, IBR isn't available — RAP is the applicable IDR plan. Confirm your eligibility with your servicer.

Analytical summary by profile — for illustrative reference only:

For most borrowers, waiting past the 90-day transition window comes with real financial risk — higher Standard Plan payments and lost PSLF qualifying months. Auto-enrollment into the Standard Plan produces significantly higher monthly payments and earns no PSLF credit. Individual situations vary. If you're uncertain about your next step, talk to your servicer or a qualified student loan advisor before the deadline.
