IBR vs RAP for 2026 Medical School Graduates: Which Plan Wins

You graduated in May 2026 with $247,000 in federal student loans — the median debt load for new MD graduates according to AAMC's 2024 data. Your intern salary is $63,000. You have exactly one question: which repayment plan do you sign up for?

For the first time in years, the answer isn't complicated by four competing income-driven options. SAVE is dead — vacated by the 8th Circuit on March 10, 2026. PAYE closed to new enrollees on July 1, 2026. You're left with two real choices: Income-Based Repayment (IBR) and the brand-new Repayment Assistance Plan (RAP). The problem is that almost nobody in your residency program understands the difference, and picking wrong could cost you tens of thousands of dollars over the next decade.

This article breaks down exactly how IBR vs RAP stacks up for 2026 medical school graduates — payment amounts, forgiveness timelines, PSLF eligibility, and the specific scenarios where each plan wins.

Why IBR vs RAP Is the Only Question That Matters for 2026 Medical Graduates

Before 2026, residents had four income-driven repayment options: IBR, PAYE, REPAYE, and SAVE. Now the landscape has collapsed into two:

• IBR — the long-standing plan, available to any borrower with a partial financial hardship, capping payments at 10% of discretionary income for new borrowers (those who took out their first federal loan after July 1, 2014). Forgiveness at 20 years.
• RAP (Repayment Assistance Plan) — brand new, applies only to loans first disbursed on or after July 1, 2026. This is the critical eligibility gate most residents don't check first.

If your loans were disbursed before July 1, 2026 — which is true for virtually every student who started medical school before fall 2022 — RAP is not available to you. IBR is your default income-driven option. Full stop.

If you are a 2026 graduate who received loans disbursed on or after July 1, 2026 (a small subset of bridge or supplemental disbursements, or incoming MS1s starting July 2026), then RAP becomes relevant. Most M4s reading this article are IBR-only.

This distinction matters enormously, so confirm your loan disbursement dates in studentaid.gov before you read another word.

How IBR Payments Work During Residency (With Real Numbers)

Under IBR for new borrowers post-July 2014, your monthly payment is capped at 10% of discretionary income, defined as your adjusted gross income minus 225% of the federal poverty guideline for your household size.

Let's run the numbers for a single PGY-1 in 2026:

• Gross income: $63,000
• 225% of federal poverty line (single person, 2026 estimate): ~$33,750
• Discretionary income: $63,000 − $33,750 = $29,250
• 10% of that: $2,925/year → $244/month

On a $247,000 balance at 7.05% interest (the 2024–2025 grad PLUS rate was 9.08%, but direct unsubsidized for grad students was 8.08%; let's use 7.05% for illustrative purposes), you're accruing roughly $1,454/month in interest. Your $244 payment doesn't come close to covering it. Your balance will grow — and that's actually fine if you're pursuing PSLF.

Across a standard 3-year internal medicine residency, followed by fellowship, you might spend 4–7 years in residency/fellowship. At $244–$350/month during that entire stretch, you accumulate qualifying PSLF payments while minimizing cash outflow. For physicians targeting PSLF, IBR during residency is a near-universal recommendation.

How RAP Works — And Who It Actually Applies To

RAP replaces SAVE as the new income-driven option for loans disbursed July 1, 2026 and later. The plan is structured differently from IBR in several key ways:

Payment calculation: RAP uses a sliding scale based on income, starting lower than IBR at very low incomes but converging or exceeding IBR payments at higher income levels. The exact percentage schedule is still being finalized in regulation, but early Department of Education guidance suggests payments will range from approximately 5% to 10% of discretionary income depending on income bracket.

Forgiveness timeline: 20 years for undergraduate borrowers, 25 years for graduate borrowers — longer than new-borrower IBR's 20-year term.

PSLF eligibility: Yes, RAP payments count toward PSLF. This is confirmed in the 2026 regulatory framework.

Interest subsidy: RAP includes an interest coverage provision similar to what SAVE had — unpaid interest above your payment does not capitalize as long as you remain enrolled. This is meaningfully better than IBR, where interest does capitalize in certain circumstances.

The catch: If your loans predate July 1, 2026, you cannot enroll in RAP. Period.

IBR vs RAP Side-by-Side: The Key Differences

For most 2026 MD graduates, this table resolves to: you're on IBR. That's not a bad outcome. IBR is a proven, court-tested plan that has produced tens of thousands of PSLF approvals.

The PSLF Lens: IBR Still Wins for Residents at Academic Centers

If you're training at a nonprofit academic medical center or public hospital — which covers the majority of U.S. residency programs — IBR remains the strongest tool available. Every residency month on IBR with an eligible employer counts toward your 120 qualifying PSLF payments.

A 5-year surgical resident who starts IBR on July 1, 2026 has 60 qualifying payments before their first day as an attending. That's halfway to forgiveness before you sign your first employment contract.

The math gets dramatic for primary care: a family medicine physician with $247,000 in loans who spends 10 years at a nonprofit hospital and qualifies for PSLF walks away from that balance entirely — tax-free. The PSLF vs aggressive payoff comparison shows just how large this gap becomes over a 15-year horizon.

When RAP Would Win (For the Minority Who Qualify)

For incoming MS1s starting in fall 2026 who receive their first disbursement on or after July 1, 2026, RAP will become relevant at graduation. Here's where RAP has a real edge:

Interest doesn't snowball. Under IBR, a resident making $244/month while accruing $1,454/month in interest technically doesn't have that unpaid interest capitalize immediately — but the mechanics are less protective than RAP's explicit subsidy provision. Over a 5-year residency, the difference in ending loan balance could be $20,000–$40,000.

Lower payments at very low incomes. At intern-year salary levels, RAP's sliding scale may produce payments $30–$80/month lower than IBR, which matters when you're paying resident rent in San Francisco or New York.

Longer forgiveness window is actually neutral for PSLF pursuers. If you're going for PSLF, you get forgiveness at 120 payments regardless of whether your plan's non-PSLF forgiveness term is 20 or 25 years. The 25-year horizon only matters if you leave PSLF-eligible employment, which is worth planning around.

The tradeoff: if you don't achieve PSLF and ride RAP to term, you're waiting an extra five years for forgiveness compared to IBR. For high earners who eventually move to private practice — common in orthopedic surgery, dermatology, and radiology — that extra five years of payment accumulation is worth modeling carefully.

The Refinancing Question: When Neither Plan Is Right

There is a subset of 2026 graduates for whom IBR and RAP are both wrong answers: physicians who are certain they will not pursue PSLF, plan to pay off loans aggressively within 5–7 years, and are entering high-income specialties out of residency.

A neurosurgery attending earning $650,000 carrying $300,000 in loans has no business on an income-driven plan as an attending. The income-driven payment would be enormous, and the forgiveness timeline is irrelevant — they'll be debt-free in 3 years with aggressive payoff. Refinancing to a 5-year private loan at 5.5%–6.5% saves them roughly $80,000–$120,000 in interest compared to running out the federal loan rate.

If this describes your trajectory, see PSLF vs refinancing for attending physicians and explore current refinancing rates at /refinance.

The decision tree is simple:

• Nonprofit employer likely → Stay federal, use IBR, pursue PSLF
• Private practice certain �� Model aggressive payoff, consider refinancing as attending
• Unsure → Stay federal through residency, reassess at the PGY transition

Frequently Asked Questions: IBR vs RAP for 2026 Medical Graduates

Can 2026 medical graduates enroll in RAP? Only if they have loans first disbursed on or after July 1, 2026. Most M4s who graduated in May or June 2026 took their last disbursements in 2025 or early 2026, making them ineligible for RAP. Their income-driven default is IBR.

Is IBR or RAP better for PSLF? Both plans generate qualifying PSLF payments. For borrowers eligible for both, RAP's interest subsidy means a lower balance if PSLF falls through, but payment counts toward 120 qualifying payments work the same way under either plan. Eligibility — not plan preference — is the deciding factor.

What happened to SAVE and PAYE in 2026? SAVE was vacated by the 8th Circuit Court of Appeals on March 10, 2026. PAYE was closed to new enrollees on July 1, 2026, as part of the Higher Education Act regulatory changes. New graduates can no longer enroll in either plan.

What is the IBR payment for a typical PGY-1 resident? For a single resident earning approximately $63,000 with the standard deductions, IBR payments typically fall between $220–$270/month in 2026. This is based on 10% of discretionary income (AGI minus 225% of the federal poverty line). Your exact payment depends on household size, filing status, and any pretax deductions like 403(b) contributions.

Should residents on IBR worry about interest accrual? Yes, but not in the way most residents fear. Your balance will grow during residency — by $30,000–$60,000 or more depending on balance and length of training. That's expected and acceptable if you're pursuing PSLF, because the entire remaining balance is forgiven tax-free at 120 payments. If you're not pursuing PSLF, that accruing interest is a real cost that should factor into your repayment strategy. See IBR vs standard repayment for doctors for a full comparison.
