How the RAP Interest Subsidy Works for Physicians (2026)

The Repayment Assistance Plan's interest subsidy sounds almost too good to be true. Here's what it actually does: the government pays any interest that accrues beyond what you're putting toward your loans, keeping your balance flat if your income stays low. For a resident earning $65,000 to $85,000 with $250,000 in debt, that's genuinely attractive. But here's the catch—the real value of this subsidy depends heavily on your specific situation. For most physicians, Income Based Repayment (IBR) still comes out ahead anyway.

What Is the RAP Interest Subsidy?

The One Big Beautiful Bill Act created the Repayment Assistance Plan, which launches July 1, 2026. One of its key features is an interest subsidy. If your monthly RAP payment falls short of the interest accruing on your loans, the government covers the difference. Your balance doesn't grow.

Compare this to IBR: you got a partial subsidy for the first three years on subsidized loans only. Now compare it to the SAVE plan that just got struck down—it provided unlimited interest coverage. That's why SAVE's collapse matters so much. Someone paying $400 monthly on $2,000 in monthly interest saw their debt stay flat. RAP does the same thing. But here's where they differ: with IBR, your unsubsidized loan balance actually grew from day one.

RAP subsidy rule: The government covers 100% of any unpaid interest across all loan types. Your balance doesn't increase as long as your RAP payments remain below the interest due.

The critical limitation: You're only eligible if your loans were disbursed on or after July 1, 2026. Anyone who started medical school before then? They're stuck with IBR.

Who Actually Benefits from the RAP Interest Subsidy

Monthly interest on $250,000 at 7.05% runs $1,469. That's your baseline. Now consider when your RAP payment—which equals 10% of discretionary income (AGI minus 225% of the poverty level)—falls short of that.

Sample calculation for a resident earning $70,000 AGI:

• Poverty level at 225%: approximately $33,300
• Discretionary income: $70,000 − $33,300 = $36,700
• RAP payment (10% of discretionary income): $3,670 annually, or $306 monthly

Your monthly interest is $1,469. Your RAP payment is $306. The subsidy covers the $1,163 gap. That's $13,956 per year in interest the government pays for you.

Not bad. But remember—only residents and medical students with loans starting July 2026 or later qualify. Everyone else doesn't get this.

Comparing the RAP Subsidy to IBR's Subsidy

For incoming MS1s in July 2026 and beyond, here's how the subsidies stack up:

For current medical students and residents: IBR is your option—and there's no interest subsidy. Your balance will grow during training. Use the MedDebt Calculator to model what your balance looks like when you hit attending salary.

For MS1s starting July 2026 or later: RAP becomes your income-driven option, and that subsidy genuinely helps during residency. Here's the tradeoff though: RAP takes 30 years to forgive your loans (versus IBR's 20–25 years), and it lacks IBR's payment cap for high earners. Once you're practicing and earning well, IBR might serve you better over the long run. Check our RAP versus IBR comparison for the details on how this plays out during your attending years.

Subsidy Math for a Full Medical Training Cycle

Picture a student starting medical school in September 2026 with $250,000 in loans eligible for RAP. They follow the typical path: four years of medical school (payments deferred), three years of Internal Medicine residency earning $65,000–$75,000 annually, then attending.

Medical School (4 years, payments deferred): No RAP payments are due. Interest still accrues though—and here's the key: the RAP subsidy doesn't apply during deferment. It only kicks in when you're actively repaying. So by graduation, your balance has ballooned to around $316,000 (that's $250,000 plus roughly 7% annual interest compounding).

Residency Years (PGY 1–3, $65,000–$75,000 AGI): In year one, your RAP payment sits around $270 monthly. Meanwhile, monthly interest on $316,000 hits approximately $1,856. The subsidy picks up the remaining $1,586 per month—roughly $19,000 annually.

Over three residency years, this subsidy prevents about $55,000–$60,000 in balance growth. That money would otherwise compound through your entire attending career. Significant? Yes. Available to current borrowers? No.

Attending Years (post-residency): Once your income reaches $250,000 or higher, your RAP payment will exceed the monthly interest. The subsidy stops applying. You pay what you owe, and the subsidy becomes irrelevant.

When the RAP Subsidy Matters (and When It Doesn't)

You benefit most if you:

• Spend residency and fellowship at lower income levels (your payment is much smaller than accruing interest).
• Train in a long specialty like Cardiothoracic Surgery, Neurosurgery, or a pediatric subspecialty requiring additional fellowship. Seven-plus years at low income means years of covered interest.
• Have substantial debt relative to your early-career income.

The subsidy won't help much if you:

• Finish training and move into practice earning well above $250,000 (your payments exceed interest immediately).
• Aggressively pay down loans anyway (you're already paying more than interest accrues).
• Can't access RAP because your loans predate July 2026 (you're locked into IBR).
• Pursue Public Service Loan Forgiveness and expect forgiveness in ten years anyway.

How PSLF Interacts

Physicians targeting PSLF should pursue it regardless of whether you qualify for RAP or IBR. Ten-year forgiveness is the goal. Use the IDR quiz at [/quiz] to find which plan minimizes your out-of-pocket spending while chasing PSLF forgiveness based on your income. The interest subsidy doesn't change your strategy here. It doesn't matter if your balance is $200,000 or $400,000 when forgiveness arrives in a decade—what matters is the forgiveness itself.

PSLF-seeking physicians should still pursue it regardless of RAP versus IBR eligibility. The 10-year forgiveness is what counts. Use the IDR quiz at [/quiz] to determine which plan saves you the most money for PSLF based on your income.

One Catch: Refinancing

Refinance to a private loan, and you immediately lose the RAP subsidy and all federal protections. Residents and fellows should almost never refinance—RAP subsidy during training is real money that private lenders can't match. Wait until you're an attending with stable income before even considering it. Our refinancing page has the full pros and cons breakdown.

Frequently Asked Questions

Does RAP subsidy apply to my existing loans? No. Only loans disbursed on or after July 1, 2026 qualify. Anything from 2025–26 and earlier doesn't qualify. You'll use IBR.

Does the subsidy cover interest while I'm in school? No. During deferment in medical school, you get no subsidy on accrued interest. Once you graduate and enter repayment, the subsidy activates.

What happens if I switch from RAP to IBR later? You lose the subsidy. Interest starts accruing on unpaid amounts under IBR. The subsidy only exists within the RAP plan itself.

Is RAP as good as SAVE was? They're similar in structure—both covered 100% of interest across all loan types. The difference: SAVE forgave undergrad loans after 20 years and graduate loans after 25 years. RAP takes 30 years uniformly. SAVE was better for most physicians. RAP is the new option for loans starting in 2026.

Will this subsidy last forever? Unknown. SAVE ran from 2023 until 2026, then got struck down. RAP is written into law, making it harder to eliminate, but Congress could still amend it. Don't build your entire financial plan assuming this subsidy never changes.
