IBR vs. RAP for Medical Residents: Which Student Loan Plan Should You Choose in 2026?

What Happened to SAVE, PAYE, and ICR?

Before getting into the IBR vs. RAP comparison, a fast recap of where things stand.

The SAVE plan is gone. A federal court order ended it on March 10, 2026, and every SAVE borrower has to move to another plan. The One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, created the Repayment Assistance Plan as its replacement.

PAYE and ICR are being phased out. Both plans end no later than July 1, 2028. If you are currently on either plan and do not pick a new one before then, your loans are automatically moved to RAP (or to IBR, for loans RAP can't take, such as consolidated Parent PLUS loans).

IBR is permanent. Unlike PAYE and ICR, IBR was explicitly preserved by the OBBBA and will remain available indefinitely — but with a critical catch covered below.

The bottom line for residents: your two meaningful options going forward are IBR and RAP. Understanding the difference between them is worth real money over the course of a physician's career.

What Is RAP and How Does It Calculate Your Payment?

The Repayment Assistance Plan (RAP) is the new federal income-driven repayment plan created by the OBBBA. It launched July 1, 2026, and is the only income-driven option for anyone with a federal loan first disbursed on or after that date, including a new consolidation loan.

RAP calculates your monthly payment as a percentage of your total adjusted gross income (AGI) — not discretionary income. The percentage follows a sliding scale:

Critical difference from IBR: RAP uses your total AGI with no poverty line deduction and no payment cap. As your physician income grows up into the attending brackets, your RAP payment will grow un-capped at a flat 10%.

RAP does include a generous interest subsidy — unpaid monthly interest is waived rather than capitalized onto your balance. This prevents your loan from growing during low-income residency periods.

Forgiveness under RAP occurs after 30 years of qualifying payments, unless pursuing PSLF which remains locked at 10 years (120 payments).

What Is IBR and How Does It Calculate Your Payment?

Income-Based Repayment (IBR) has been originally available since 2009 and is one of the most physician-friendly plans that will remain available long-term.

IBR calculates your monthly payment based on discretionary income — your AGI minus 150 percent of the federal poverty guideline for your family size. The applicable percentage depends on when you first borrowed:

• New IBR (first borrowed after July 1, 2014, and before July 1, 2026): 10 percent of discretionary income, forgiveness after 20 years
• Old IBR (loans before July 1, 2014): 15 percent of discretionary income, forgiveness after 25 years

Most current residents fall under New IBR at 10 percent of discretionary income.

The feature that matters most for physicians: IBR caps your monthly payment at the 10-year Standard Repayment amount for your loan balance. No matter how high your attending salary climbs, your IBR payment cannot exceed what you would pay on a standard 10-year plan. RAP has no equivalent cap.

Both RAP and IBR qualify for PSLF (Public Service Loan Forgiveness).

The Real Math: What Each Plan Costs a Resident

Here is how the two plans mathematically compare for a typical PGY-2 resident earning $70,000 per year with $230,000 in federal student loans.

Assumptions: $70,000 gross salary, $5,000 in pre-tax deductions (401k contributions, health insurance), AGI of $65,000, family size of one, the 2026 HHS poverty guideline of $15,960 for a one-person household in the 48 contiguous states and D.C., and a 6.5% average interest rate (the default in our IDR comparison calculator).

During residency at this income level, RAP saves approximately $17 per month — modest but real.

But now look at what happens when that exact same physician finishes residency and earns $350,000 as an attending, while still pursuing PSLF:

That is about $305 a month, or roughly $3,700 a year, less than RAP at this income — and the gap widens with every raise, because RAP keeps taking 10% of AGI while IBR stays at the cap. Over the attending years of a PSLF window, that adds up to tens of thousands of dollars.

The math is crystal clear: RAP is marginally cheaper during low-income training years. But IBR is significantly cheaper — and the payment advantage compounds — as income rises toward attending levels, especially for PSLF borrowers.

IBR vs. RAP for Residents Pursuing PSLF

If you are training at a nonprofit hospital or academic medical center and planning to pursue Public Service Loan Forgiveness, the IBR vs. RAP decision has major financial consequences.

PSLF strategy is simple: minimize total payments made before the 120-payment threshold is reached. PSLF forgives the remaining balance tax-free. Every dollar you do not pay before that point is a dollar you do not owe.

Under PSLF, IBR wins for most physicians as income rises. At first the edge comes from the poverty-line deduction, which keeps a single borrower's IBR payment about $200 a month below RAP's once both plans are charging 10 percent (150% of the 2026 guideline × 10% ÷ 12 = $199.50). Then the cap takes over: in the example above, IBR stops rising at about $337,000 of AGI, while RAP keeps charging 10 percent of every dollar. Over the 5 to 7 years most physicians spend completing PSLF as attendings, that difference in monthly payment represents a substantial reduction in total amount paid before forgiveness.

Still, the simplest and safest approach for most PSLF-pursuing residents with loans from before July 1, 2026 is to enroll in IBR now and stay there.

IBR has no enrollment deadline — July 1, 2028 is when PAYE and ICR end, not IBR — and a borrower whose loans all predate July 1, 2026 can move between RAP and IBR. The door closes only if you take out a new federal loan or consolidate on or after July 1, 2026; after that, all of your loans must be repaid under RAP or the Tiered Standard Plan, and IBR is off the table. Do not borrow or consolidate without running the full numbers first.

IBR vs. RAP for Residents Not Pursuing PSLF

If you are training at a for-profit hospital, planning a private practice switch, or have already decided to refinance once you finish training, the analysis is very different.

In this scenario, you are not trying to minimize payments before forgiveness — you are trying to manage cash flow during residency while positioning to aggressively pay down or refinance the debt as an attending.

For these residents, the choice between IBR and RAP during training is less consequential because neither plan is part of a long-term forgiveness strategy. The small monthly payment difference matters less than getting your financial fundamentals in order during residency — building an emergency high-yield savings fund, starting a Roth IRA, getting disability insurance in place — so you are positioned to refinance strategically when your attending income begins.

The July 1, 2026 Line Every Resident Needs to Know

This is the most time-sensitive action item in this entire article.

• If you were on SAVE: Starting July 1, 2026, your servicer gives you a 90-day deadline to choose a new plan. If you do not choose within that window, you will be automatically enrolled in the Standard Repayment Plan or the new Tiered Standard Plan — both set a fixed payment from your balance rather than your income, and Tiered Standard payments don't count toward PSLF.
  
  Do not wait for the auto-enrollment. Go to StudentAid.gov now and apply for IBR if that is the right plan for your situation.
• If you are currently on PAYE or ICR: These plans end no later than July 1, 2028, and you must pick a new plan by June 30, 2028. However, the longer you wait to analyze your situation and choose, the more likely you are to miss the window or make the switch under time pressure without running your numbers properly.
• If any of your federal loans was first disbursed on or after July 1, 2026 (including a new consolidation loan): RAP is your only income-driven option, and IBR is no longer available for any of your loans. Your decision is RAP versus the Tiered Standard Plan — and for PSLF-eligible residents at qualifying institutions, RAP is the clear choice since the Tiered Standard Plan does not qualify for PSLF.

The Married Filing Separately Question

For married residents, one of the most powerful tools for reducing income-driven repayment payments is filing taxes as Married Filing Separately (MFS) rather than jointly. Both IBR and RAP allow you to globally exclude a spouse's income from the payment calculation when filing separately.

This matters significantly when one spouse is a resident earning $70,000 and the other earns $100,000 or more. Filing jointly would include the higher income in the payment calculation, materially increasing monthly payments. Filing separately entirely excludes it.

The trade-off is the loss of certain tax deductions available only to joint filers. Whether MFS saves money on balance requires running the combined federal and state tax implications against the loan payment savings. For many physician households, MFS produces meaningful net savings despite the lost deductions — often $5,000 to $15,000 or more annually.

One key difference between IBR and RAP on this point: IBR uses a broader definition of family size that can include household members you support even if you do not claim them as dependents. RAP counts only dependents explicitly claimed on your federal tax return. For residents with children or other dependents, IBR's broader family size definition typically produces a slightly lower payment for the same income level.
