The Saving on a Valuable Education Plan was struck down by federal courts in early 2026. Eight million borrowers are now in forbearance. Do not wait for resurrection. The plan is gone. Choose RAP, IBR, PAYE, or ICR instead.
Income-driven repayment (IDR) is the hidden superpower of the federal student loan system. While standard repayment crushes you with a fixed 10-year payment, IDR plans tie your monthly payment to your income and offer forgiveness at the end of 20–25 years. For public servants, IDR unlocks PSLF. For low-income borrowers, IDR can mean payments of $0 or near-zero in lean years.
The catch: IDR plans are complex. Five separate plans exist, each with different eligibility, payment formulas, interest subsidy rules, and forgiveness timelines. Pick the wrong one and you'll overpay by thousands. This guide dissects each plan and shows you the math.
The IDR Plan Landscape (April 2026)
| Plan | Payment Formula | Forgiveness Timeline | Interest Subsidy | PSLF Eligible? |
|---|---|---|---|---|
| RAP (New) | 5–10% AGI (sliding) | 20–25 years | Yes | Yes |
| IBR (post-2014) | 10% discretionary income | 20 years | No | Yes |
| PAYE | 10% discretionary income | 20 years | Yes | Yes |
| ICR | 20% gross income or fixed payment | 25 years | No | Yes |
| IBR (pre-2014) | 15% discretionary income | 25 years | No | Yes |
| SAVE (Struck Down) | 5% discretionary income | DEAD | No longer available | N/A |
RAP: The New Frontrunner (2026)
The Repayment Assistance Plan launched as part of Trump administration student loan policy in 2026. It operates differently from all prior IDR plans because it uses adjusted gross income (AGI) rather than discretionary income.
Payment formula: RAP uses a sliding scale. Below $10,000 AGI, you pay $0. At $10,000–$24,999 AGI, you pay 5% of AGI. At $25,000+, you pay a graduated percentage rising to 10% at $60,000+. The exact percentage varies by your loan type (undergrad vs. grad).
Forgiveness timeline: 20 years for undergrad, 25 years for graduate and Parent PLUS loans.
Interest subsidy: Unlike IBR and ICR, RAP includes a meaningful interest subsidy. If your payment doesn't cover accrued interest, the government covers the gap. This prevents your balance from growing.
PSLF eligibility: RAP qualifies for PSLF. 120 qualifying payments = forgiveness.
Key advantage: For lower-income borrowers ($20K–$50K income), RAP typically beats all other plans because the 5–10% AGI payment is lower than the 10% discretionary income payment under IBR and PAYE.
Key disadvantage: RAP is brand new. Borrowers are still learning it. Documentation for deferment and forbearance periods is unclear. Payments recalculate annually based on new tax returns.
IBR (Income-Based Repayment) — Still Viable
IBR has been the workhorse of IDR for fifteen years. Two versions exist: pre-2014 (for borrowers who had loans before 2014) and post-2014 (for all newer borrowers).
Post-2014 IBR (most common): 10% of discretionary income, 20-year forgiveness timeline.
Discretionary income calculation: Your AGI minus 150% of the poverty line for your family size. At the federal poverty line level, discretionary income is $0, so your payment is $0.
Example: You earn $40,000 AGI and are single. The 150% poverty line for a single person is about $19,500. Your discretionary income is $40,000 - $19,500 = $20,500. Your IBR payment is 10% of $20,500 = $2,050/year or ~$171/month.
Interest subsidy: IBR post-2014 does NOT include an interest subsidy. If you don't pay accrued interest, it capitalizes and begins earning interest itself. Over 20 years, this can double your effective loan balance.
PSLF eligibility: Yes. IBR payments count toward the 120-payment PSLF threshold.
Advantage: Simple, well-tested, millions of borrowers using it successfully. The 10% formula is predictable.
Disadvantage: No interest subsidy means unpaid interest spirals. If you earn low income and your 10% payment doesn't cover interest, you'll owe more at forgiveness than you borrowed.
PAYE (Pay As You Earn) — The Underrated Option
PAYE is IBR's cousin with one critical difference: it includes an interest subsidy. This single feature makes it dramatically better than IBR for many borrowers.
Payment formula: 10% of discretionary income (same as IBR post-2014).
Forgiveness timeline: 20 years.
Interest subsidy: YES. PAYE subsidizes unpaid interest. If your payment doesn't cover accrued interest, the government pays the difference. Your balance doesn't grow through unpaid interest.
Eligibility: Must be a "new borrower" as of October 1, 2007. Notably, many borrowers don't qualify for PAYE due to this cutoff. Check StudentAid.gov to verify.
PSLF eligibility: Yes.
Advantage: Interest subsidy is gold. Over a 20-year period with low income, the subsidy can save $20,000–$50,000 in accumulated unpaid interest.
Disadvantage: Eligibility is restricted. If you borrowed before 2007, you don't qualify. Eligibility rules are notoriously confusing on StudentAid.gov.
ICR (Income-Contingent Repayment) — The Legacy Plan
ICR is the oldest IDR plan, dating to the 1990s. It's largely superseded by newer plans but remains available.
Payment formula: The greater of (1) 20% of gross income or (2) a fixed amount based on a 12-year standard repayment amortization. Most borrowers end up paying the 20% formula.
Forgiveness timeline: 25 years.
Interest subsidy: None. Unpaid interest capitalizes.
PSLF eligibility: Yes, though rarely optimal for PSLF because the 25-year timeline is longer than other plans.
Why choose ICR? For very high-income borrowers or those ineligible for other plans. ICR's 20% gross-income ceiling makes it the only IDR option for borrowers earning above certain thresholds who don't qualify for PAYE.
Disadvantage: Longer forgiveness timeline (25 vs. 20 years) and no interest subsidy make it suboptimal in most scenarios.
Step-by-Step: How to Choose Your Plan
The Decision Tree
- Check your PSLF eligibility. Do you work (or plan to work) for a government agency or nonprofit for 10+ years? If yes, go to step 2. If no, go to step 3.
- You need PSLF—choose between RAP, IBR, PAYE, or ICR. Run the Loan Simulator for each. Pick the plan with the lowest payment. PAYE is best if eligible (interest subsidy). RAP is best if you earn under $50K. IBR is the fallback.
- You don't need PSLF—check your income level. If under $50K, RAP likely wins. If $50K–$80K, compare RAP vs. IBR. If above $80K, standard repayment or refinancing likely beats any IDR plan.
- Run the numbers in the Loan Simulator for your top two choices. Compare monthly payment, total interest paid, and forgiveness amount. Choose the lower total cost option.
- Apply on StudentAid.gov. You need to certify your income annually. Set a calendar reminder for one month before your anniversary date.
Interest Subsidies Explained: Why This Matters
The difference between plans with and without interest subsidies is the single most important factor many borrowers miss. Let me demonstrate why.
Scenario: $60,000 student loan, $30,000 income, single, 20-year forgiveness timeline.
Under IBR (10% discretionary income, NO interest subsidy): Your payment is about $200/month. Accrued interest runs roughly $250/month. You're paying $200 but owing $250 in interest. The $50 gap capitalizes yearly. After 20 years, your balance grows to ~$95,000. At forgiveness, you've overpaid by $35,000 through interest capitalization.
Under PAYE (10% discretionary income, YES interest subsidy): Your payment is the same $200/month. But the government covers the $50 gap. Your balance stays flat. After 20 years, forgiveness erases the original $60,000 with minimal additional accrual. You save roughly $35,000.
The difference between these two plans, despite identical payment formulas, is $70,000. This is why the interest subsidy is non-negotiable if you qualify for PAYE.
The federal Loan Simulator at StudentAid.gov now includes all active plans (SAVE is removed). Use it to model exact payment, forgiveness amount, and total interest for your income. It's the most accurate tool available.
FAQ: IDR Plans
Q: Can I switch between IDR plans? A: Yes, at annual recertification or anytime during the year. Switching changes your payment formula and may affect forgiveness eligibility, so model the math first on the Loan Simulator.
Q: Do I have to certify my income every year? A: Yes. IDR plans require annual income certification. Miss the deadline and you default to standard repayment. Set a calendar reminder for your anniversary date.
Q: What if my income drops mid-year? A: You can request an income-driven recalculation immediately. Don't wait until your anniversary. StudentAid.gov allows recalculation requests anytime.
Q: Is the forgiveness amount taxable? A: Yes, forgiven balance is taxable as income in the year of forgiveness. However, Trump administration proposals may change this. Plan for $10,000–$30,000 tax liability on forgiveness.
Q: Do deferment and forbearance count toward PSLF? A: No. Only qualifying payments count. Deferment and forbearance don't count. This is why staying on an active IDR plan is critical for PSLF borrowers.
