If you have federal student loans and you are trying to figure out the difference between Income-Contingent Repayment (ICR) and Income-Based Repayment (IBR), you are not alone — and you are asking the right question at exactly the right time.
The federal student loan repayment landscape is undergoing its most significant overhaul in decades. Plans are being terminated. New plans are launching. Deadlines are approaching that, if missed, could permanently lock you out of certain options. In the middle of all this change, ICR and IBR remain two of the most discussed income-driven repayment plans — but their futures could not be more different.
This guide explains exactly how ICR and IBR work, compares them side by side, and tells you what you need to know right now to make the right decision for your loans.
What Is Income-Driven Repayment — and Why Does It Matter?
Before comparing ICR and IBR specifically, it helps to understand the category they belong to.
Income-driven repayment (IDR) is a federal program that calculates your monthly student loan payment based on your income, family size, and state of residence — not your loan balance. If you owe $80,000 but earn $35,000 a year, an IDR plan can bring your monthly payment down to a manageable amount, sometimes as low as $0.
All IDR plans share three core features:
- Payments are a percentage of your discretionary income
- Any remaining balance is forgiven after a set number of years
- Payments made under IDR plans count toward Public Service Loan Forgiveness (PSLF)
Until recently, borrowers could choose from four IDR plans: IBR, ICR, PAYE, and SAVE. That is changing rapidly.
The 2026 Landscape: What Has Changed
Understanding the current state of IDR plans is essential before making any decision.
SAVE has been eliminated. The SAVE plan (formerly REPAYE) was terminated following the passage of the “One Big Beautiful Bill” in mid-2025, and a federal court vacated its underlying rule in March 2026. If you were on SAVE, you must switch plans.
PAYE and ICR are sunsetting. Both plans are being phased out, with a hard deadline of July 1, 2028. After that date, neither will be available to any borrower.
IBR is the last IDR plan standing. IBR is the only existing income-driven repayment plan that will remain available after 2028. It is the only option for borrowers who want to stay on an IDR plan for the full life of their loans.
A new plan is launching: the Repayment Assistance Plan (RAP). Starting July 1, 2026, RAP becomes available to all borrowers. For anyone whose first loan is disbursed on or after July 1, 2026, RAP is the only IDR-style option available — IBR and ICR are not accessible to new borrowers.
With that context established, here is how ICR and IBR compare for existing borrowers who still have a choice.
What Is Income-Contingent Repayment (ICR)?
ICR is the oldest of the federal income-driven repayment plans. It was introduced in the 1990s and was designed to give borrowers an alternative to the standard fixed-payment plan when their income was too low to manage those payments comfortably.
How ICR Calculates Your Payment
Under ICR, your monthly payment is the lesser of:
- 20% of your discretionary income, or
- What you would pay on a 12-year fixed repayment plan, adjusted for your income
Discretionary income for ICR is calculated as the difference between your annual income and 100% of the federal poverty guideline for your family size and state.
ICR Forgiveness Timeline
Any remaining balance is forgiven after 25 years of qualifying payments.
Who Can Use ICR?
One of ICR’s most important features is that it is the only income-driven plan that Parent PLUS loan holders can access — but only after consolidating their Parent PLUS loans into a Direct Consolidation Loan. This makes ICR uniquely valuable for parents who borrowed to fund their child’s education.
For all other borrowers with standard federal student loans, ICR is generally not the most favorable option available, since IBR typically offers lower payments.
The ICR Sunset: What It Means for You
ICR will be eliminated by July 1, 2028 under current law. If you are currently on ICR, you will need to transition to another plan before that deadline. If no action is taken, you will be automatically moved to the new Repayment Assistance Plan (RAP).
For Parent PLUS borrowers currently on ICR, this is a particularly urgent issue, since RAP eligibility rules differ significantly.
What Is Income-Based Repayment (IBR)?
IBR was introduced in 2009 as a more generous alternative to ICR. It quickly became one of the most popular repayment plans for borrowers with high debt relative to income, and it remains the most important plan in the current environment because it is the only existing IDR plan that will survive beyond 2028.
IBR Comes in Two Versions
IBR is not a single plan — it has two versions based on when you first borrowed:
Old IBR (for borrowers who had their first federal loan before July 1, 2014):
- Payment: 15% of discretionary income
- Forgiveness: after 25 years
- Discretionary income: income above 150% of the federal poverty guideline
New IBR (for borrowers whose first federal loan was on or after July 1, 2014):
- Payment: 10% of discretionary income
- Forgiveness: after 20 years
- Discretionary income: income above 150% of the federal poverty guideline
New IBR borrowers pay less per month and reach forgiveness five years earlier. If you are a recent graduate, this is likely the version that applies to you.
IBR’s Payment Cap
One of IBR’s most valuable features is its payment cap: your monthly payment under IBR will never exceed what you would pay on the standard 10-year repayment plan. This protects borrowers who see significant income growth from runaway payments.
ICR has no such cap. Under ICR, payments can grow indefinitely as your income rises.
IBR’s Interest Subsidy
Under IBR, if your monthly payment does not cover the interest accruing on your subsidized loans, the government covers the difference for the first three years. This prevents your balance from growing during the early, lower-income years of repayment.
ICR does not offer this interest subsidy.
IBR Eligibility Requirement
To qualify for IBR, your loan debt must be high relative to your income — specifically, your IBR payment must be lower than what you would pay on the standard 10-year plan. This means IBR is not available to borrowers with low debt and high income, since their income-based payment would actually be higher than their standard payment.
ICR has no such partial financial hardship requirement. Any borrower with eligible federal loans can enroll.
ICR vs IBR: Direct Comparison
| Feature | ICR | IBR (New) | IBR (Old) |
|---|---|---|---|
| Payment percentage | 20% of discretionary income (or 12-yr fixed, whichever is less) | 10% of discretionary income | 15% of discretionary income |
| Discretionary income baseline | 100% of poverty guideline | 150% of poverty guideline | 150% of poverty guideline |
| Forgiveness timeline | 25 years | 20 years | 25 years |
| Payment cap | No cap | Capped at standard 10-yr payment | Capped at standard 10-yr payment |
| Interest subsidy | None | Yes, subsidized loans, first 3 years | Yes, subsidized loans, first 3 years |
| Parent PLUS eligibility | Yes (after consolidation) | No | No |
| Financial hardship requirement | None | Yes | Yes |
| PSLF eligible | Yes | Yes | Yes |
| Plan sunset | July 1, 2028 | No sunset — survives long-term | No sunset — survives long-term |
| Available to new borrowers after July 2026 | No | No | No |
Which Plan Results in Lower Monthly Payments?
For most borrowers, IBR will produce a lower monthly payment than ICR. Here is why:
ICR uses 20% of your discretionary income, calculated above 100% of the poverty line. IBR uses 10% (new borrowers) or 15% (old borrowers) of income above 150% of the poverty line. The higher baseline and lower percentage both work in IBR’s favor for most income levels.
Example: A single borrower earning $50,000 per year in 2026.
- Federal poverty guideline (single person, 2026): approximately $15,650
- ICR discretionary income: $50,000 − $15,650 = $34,350 → 20% = $572/month
- New IBR discretionary income: $50,000 − ($15,650 × 1.5) = $26,525 → 10% = $221/month
- Old IBR discretionary income: $50,000 − ($15,650 × 1.5) = $26,525 → 15% = $332/month
In this example, New IBR produces a payment that is less than half the ICR payment. Even Old IBR is meaningfully lower.
The one scenario where ICR might produce a lower payment is when the 12-year fixed plan calculation comes out lower than 20% of income. This is relatively uncommon but worth checking if you have a very large loan balance relative to your income.
Which Plan Is Better for PSLF?
Both ICR and IBR qualify for Public Service Loan Forgiveness. Payments made under either plan count toward the 120 qualifying payments required to reach tax-free forgiveness after 10 years of public service employment.
However, since lower payments under IBR mean more of your balance remains at the 10-year mark, IBR is often the better strategy for PSLF borrowers — especially those with high loan balances. The larger the remaining balance at forgiveness, the more value you extract from the program.
That said, the sunset of ICR by July 2028 means that PSLF borrowers currently on ICR need to transition to IBR or RAP before that deadline — ideally before July 1, 2028, and sooner if possible to avoid administrative complications.
The New Alternative: Repayment Assistance Plan (RAP)
Any discussion of ICR vs IBR in 2026 would be incomplete without mentioning the Repayment Assistance Plan (RAP), which launched July 1, 2026.
RAP replaces the discretionary income formula with a tiered percentage of adjusted gross income (AGI) across 11 income brackets. Payments range from 1% to 10% of AGI, with a minimum payment of $10 per month (there are no $0 payment months under RAP). Unpaid interest is waived monthly rather than capitalized, so your balance cannot grow through negative amortization.
RAP also counts toward PSLF. Forgiveness comes after 30 years — longer than either IBR or ICR.
Key consideration: RAP has no payment cap. For borrowers with rising incomes, IBR’s cap may become increasingly valuable over time. For borrowers with more modest income trajectories, RAP’s interest waiver and lower payment floor may be more attractive.
For new borrowers (loans first disbursed on or after July 1, 2026), RAP is the only IDR-style option — IBR and ICR are not available.
Who Should Choose ICR in 2026?
Given its higher payments and July 2028 sunset, ICR is rarely the best choice for most borrowers in 2026. However, it remains the right option in one specific scenario:
Parent PLUS loan borrowers who have consolidated their loans into a Direct Consolidation Loan have only ICR available to them among the existing IDR plans. IBR is not available for Parent PLUS loans. For these borrowers, ICR remains the primary income-driven option — at least until RAP launches and until the 2028 sunset forces a transition.
If you are a Parent PLUS borrower currently on ICR, start planning your transition now. The 2028 deadline will come faster than expected, and the administrative process of switching plans takes time.
Who Should Choose IBR in 2026?
IBR is the right choice for most existing borrowers who:
- Have federal Direct Loans or FFEL loans (not Parent PLUS)
- Qualify based on partial financial hardship
- Want an IDR plan that will remain available for the full life of their loans
- Are pursuing PSLF and want a plan guaranteed to remain eligible
Critical deadline: To access IBR, you must not borrow any new federal loans after July 1, 2026, and you must enroll in IBR before July 1, 2028. Miss the deadline and you are permanently locked out of IBR.
“compare your estimated payments under each plan”
If you are currently on SAVE, PAYE, or ICR and considering your next move, IBR is the plan most financial advisors are recommending as a stable long-term foundation.
Common Mistakes When Choosing Between ICR and IBR
Assuming ICR and IBR are interchangeable. They are not. ICR’s payment formula is fundamentally different, and its sunset makes it unsuitable as a long-term strategy for most borrowers.
Forgetting to recertify annually. Both ICR and IBR require annual income recertification. Missing the deadline can cause your payment to spike to the standard amount and interrupt your progress toward forgiveness.
Refinancing to private loans. If you refinance your federal loans into private loans, you permanently lose access to both ICR and IBR — and to PSLF. This is an irreversible decision that eliminates all federal protections.
Assuming all forgiveness is tax-free. PSLF forgiveness is currently tax-free at the federal level. But forgiveness after 20 or 25 years under an IDR plan may be taxable as income in the year it is received, depending on current tax law at that time.
Not checking employer eligibility for PSLF. Being on an eligible repayment plan is only half the equation. Your employer must also qualify. Verify this annually using the PSLF Help Tool at studentaid.gov.
Step-by-Step: How to Choose Your Plan Right Now
Step 1: Identify what type of loans you have. Parent PLUS loans are not eligible for IBR. If that is your situation, ICR (before 2028) or RAP are your options.
Step 2: Determine when you first borrowed. If your first federal loan was before July 1, 2014, you may qualify for Old IBR (15%, 25 years). If it was on or after July 1, 2014, you likely qualify for New IBR (10%, 20 years).
Step 3: Calculate your estimated payment under each plan. Use the Loan Simulator tool at studentaid.gov to compare actual payment amounts based on your income and family size. Do not guess — run the numbers.
Step 4: Consider your career path. If you work or plan to work for a qualifying nonprofit or government employer, PSLF changes the calculus entirely. Lower payments under IBR leave more balance available for forgiveness.
Step 5: Enroll before the deadlines. If you want IBR and you have not enrolled, do it before July 1, 2028. Do not wait for a reminder — the deadline is firm.
Final Verdict: ICR vs IBR in 2026
For most borrowers, IBR is the clear winner over ICR in 2026. It offers lower payments, a payment cap, a partial interest subsidy for subsidized loans, and — most importantly — it is the only existing income-driven plan that will remain available after July 2028.
ICR remains relevant only for Parent PLUS borrowers who have exhausted other options, and even then only as a bridge strategy until RAP provides a comparable alternative.
If you are an existing borrower currently on SAVE, PAYE, or ICR and wondering where to go next, IBR is the destination that most financial advisors are pointing toward — provided you meet the eligibility requirements and act before the 2028 cutoff.
