If your federal student loan payment feels like it swallows your whole paycheck, you are not alone. Income-driven repayment (IDR) plans exist specifically to make monthly payments more manageable by tying what you owe each month to what you actually earn. But there are four different IDR plans, each with its own rules, and figuring out which one fits your situation can feel overwhelming. This guide breaks down every plan side by side so you can make a confident choice.
What All IDR Plans Have in Common
Before we dig into the differences, here is what every income-driven repayment plan shares:
- Payments are based on your income and family size, not your loan balance.
- You must recertify your income every year. Miss the deadline and your payment jumps to the standard 10-year amount until you recertify. You can recertify through your servicer or at studentaid.gov.
- Any remaining balance is forgiven after 20 or 25 years of qualifying payments, depending on the plan.
- All four plans count toward Public Service Loan Forgiveness (PSLF), though some are a better strategic fit than others.
- Payments can be as low as $0 if your income is low enough. A $0 payment still counts as a qualifying payment for forgiveness.
The Four IDR Plans at a Glance
Here is a structured comparison of each plan's core features. We will go deeper on each one below.
| Feature | SAVE (formerly REPAYE) | PAYE | IBR | ICR | |---|---|---|---|---| | Payment percentage | 5% undergrad / 10% grad | 10% | 10% (15% if you borrowed before July 1, 2014) | 20% or 12-year fixed amount (whichever is less) | | Income exemption | 225% of federal poverty line (~$32,800 for a single filer in 2024) | 150% of federal poverty line (~$22,590 for a single filer) | 150% of federal poverty line (~$22,590 for a single filer) | 100% of federal poverty line (~$15,060 for a single filer) | | Forgiveness timeline | 20 years (undergrad) / 25 years (grad); 10 years if original balance was $12,000 or less | 20 years | 20 years (new borrowers after July 1, 2014) / 25 years (older borrowers) | 25 years | | Interest subsidy | Full interest waiver on unpaid interest | Subsidy on subsidized loans for 3 years | Subsidy on subsidized loans for 3 years | None | | Spouse income | Not included if you file taxes separately | Not included if you file separately | Not included if you file separately | Always included regardless of tax filing status | | Eligible loans | Direct Loans only | Direct Loans only (must be a new borrower as of Oct 1, 2007, with a disbursement after Oct 1, 2011) | Direct Loans and FFEL | Direct Loans only |

SAVE Plan (Formerly REPAYE)
The SAVE plan — Saving on a Valuable Education — launched in 2023 as a replacement for REPAYE. On paper, it is the most generous IDR plan available. Here is what makes it stand out:
Payment Calculation
SAVE uses 5% of discretionary income for undergraduate loans and 10% for graduate loans. If you have both undergrad and grad debt, your rate is a weighted average of the two. Discretionary income is everything you earn above 225% of the federal poverty line. For a single filer in 2024, that means roughly the first $32,800 of your income is protected — compared to just $22,590 under PAYE and IBR.
In practical terms, a single borrower earning $45,000 with only undergraduate debt would pay about $51 per month under SAVE, compared to roughly $187 under PAYE or IBR.
Interest Waiver
This is a big deal. Under SAVE, if your monthly payment does not cover all the interest that accrues, the government waives the remaining interest entirely. Your balance never grows beyond what you originally owed. Under other IDR plans, unpaid interest can capitalize (get added to your principal), meaning you end up owing more than you borrowed.
Early Forgiveness for Small Balances
If your original loan balance was $12,000 or less, SAVE offers forgiveness after just 10 years of payments. For every additional $1,000 borrowed above $12,000, the timeline adds one year, up to the standard 20-year cap for undergraduate loans and 25 years for graduate loans.
The Litigation Challenge
Here is the important caveat: as of early 2025, the SAVE plan is caught up in federal court litigation. Multiple lawsuits challenged the Department of Education's authority to implement parts of the plan. Courts issued injunctions that blocked key SAVE provisions, and borrowers enrolled in SAVE were placed into an interest-free forbearance while the legal situation was sorted out.
What this means for you: The future of SAVE depends on ongoing court decisions and the current administration's policy direction. If you are considering SAVE, check studentaid.gov for the latest status before applying. If SAVE is unavailable, IBR and PAYE remain accessible alternatives.
PAYE (Pay As You Earn)
PAYE was the gold standard before SAVE came along, and it still has a lot going for it.
Payment Calculation
You pay 10% of discretionary income, with the income exemption set at 150% of the federal poverty line (about $22,590 for a single filer). Payments are capped at what you would pay on the standard 10-year plan, so if your income rises significantly, your payment will not exceed that ceiling.
Forgiveness and Interest
Remaining balances are forgiven after 20 years. For the first three years, the government covers any unpaid interest on subsidized loans. After that, unpaid interest can capitalize — but only up to 10% of your original balance.
Eligibility
PAYE has the tightest eligibility window. You must be a "new borrower" — meaning you had no outstanding balance on a Direct Loan or FFEL loan as of October 1, 2007, and you received a new Direct Loan disbursement on or after October 1, 2011. If you have been borrowing since before 2007, PAYE is not available to you.
IBR (Income-Based Repayment)
IBR is the most widely available IDR plan because it covers both Direct Loans and older FFEL loans.
Payment Calculation
If you are a new borrower (no outstanding balance as of July 1, 2014), you pay 10% of discretionary income with forgiveness after 20 years. If you borrowed before that date, you pay 15% of discretionary income with forgiveness after 25 years. Like PAYE, your payment is capped at the standard 10-year amount.
Partial Financial Hardship Requirement
Unlike SAVE, you must demonstrate a "partial financial hardship" to enroll in IBR. This means your IBR payment must be less than what you would pay on the 10-year standard plan. If your income eventually rises above that threshold, you stay on IBR but your payment is capped at the standard amount.
Interest Subsidy
The government covers unpaid interest on subsidized loans for the first three years. After that, interest accrues but does not capitalize as long as you stay on the plan.
ICR (Income-Contingent Repayment)
ICR is the oldest IDR plan and generally the least favorable, but it fills an important niche.
Payment Calculation
You pay the lesser of 20% of discretionary income or the amount you would pay on a 12-year fixed plan, adjusted for income. The income exemption is only 100% of the federal poverty line (about $15,060 for a single filer), which means more of your income is counted.
Why ICR Still Matters
ICR is the only IDR plan available for Parent PLUS loans — but only after you consolidate them into a Direct Consolidation Loan. If you are a parent who borrowed PLUS loans and need income-driven payments, ICR is your only path. Forgiveness comes after 25 years.
Spouse Income
One unique downside: ICR always factors in your spouse's income, even if you file taxes separately. Every other IDR plan lets you exclude spousal income by filing separately.
Which Plan Gives You the Lowest Payment?
For most borrowers, SAVE produces the lowest monthly payment — sometimes dramatically lower — because of its higher income exemption and the 5% rate for undergraduate loans. If SAVE is unavailable due to the litigation challenges, PAYE is typically the next-best option for eligible borrowers, followed by IBR.
Quick example for a single borrower earning $50,000 with $35,000 in undergraduate Direct Loans:
- SAVE: ~$72/month (if available)
- PAYE: ~$228/month
- IBR (new borrower): ~$228/month
- ICR: ~$581/month
These are estimates. Your actual payment depends on family size, state of residence, and specific income. Use the Loan Simulator at studentaid.gov to run your own numbers.
Which Plan Works Best with PSLF?
All four IDR plans qualify for Public Service Loan Forgiveness, which forgives your remaining balance after 120 qualifying payments (10 years) while working for a qualifying employer. Since PSLF forgiveness comes at year 10 regardless of which IDR plan you pick, the smart strategy is to choose the plan with the lowest monthly payment so you pay the least before forgiveness kicks in. That usually means SAVE (if available) or PAYE.
How to Apply
You can apply for any IDR plan through the Income-Driven Repayment Plan Request at studentaid.gov. The application takes about 10 minutes. You will need your FSA ID and recent income information (the application can pull your tax data automatically with your consent). Your loan servicer will process the request and notify you of your new payment amount, typically within a few weeks.
Recertification: Do Not Forget This Step
Every IDR plan requires you to recertify your income and family size once a year. Your servicer will notify you when it is time, but do not rely on that reminder alone — mark your calendar. If you miss the deadline:
- Your monthly payment resets to the standard 10-year repayment amount.
- Any unpaid interest may capitalize, increasing your total balance.
- You will need to reapply to get back on your IDR plan.
You can recertify early if your income drops or your family size changes. There is no penalty for recertifying ahead of schedule.
Tax Implications of Forgiveness
Here is where things get tricky. Under the American Rescue Plan Act, any student loan balance forgiven through IDR plans is tax-free through December 31, 2025. After that date, the law is set to revert to its previous rule, where forgiven loan balances are treated as taxable income by the IRS.
What does that mean in real numbers? If you have $80,000 forgiven in 2026 and you are in the 22% tax bracket, you could owe roughly $17,600 in federal income tax on the forgiven amount. That is a serious sum, and it is worth planning for.
Congress could extend the tax-free provision, but as of now there is no guarantee. Keep this on your radar, especially if your forgiveness date is approaching. A tax professional can help you set up a savings strategy just in case.
Roadblocks to Watch
- SAVE plan uncertainty. The litigation could reshape or eliminate the plan entirely. Stay current on developments at studentaid.gov before making decisions that depend on SAVE being available.
- Recertification lapses. Missing your annual deadline can undo months of progress and add capitalized interest to your balance. Set a recurring reminder well ahead of the due date.
- Filing taxes separately. Excluding your spouse's income lowers your IDR payment, but filing separately often means losing valuable tax credits and deductions. Run the numbers both ways to see which approach actually saves you more money overall.
- Forgiveness tax bomb. If the tax-free provision expires after 2025, a large forgiven balance could trigger a significant tax bill. Start setting aside funds or consult a tax advisor as your forgiveness date approaches.
- Negative amortization. On plans other than SAVE, your balance can grow over time if your payment does not cover all accruing interest. This does not affect your forgiveness timeline, but it can feel discouraging — and it matters if you ever leave the plan or refinance.
- Parent PLUS limitations. Parent PLUS borrowers can only access ICR, and only after consolidation. Consolidation restarts your PSLF payment count, so weigh that tradeoff carefully.
The Bottom Line
Income-driven repayment plans are one of the most powerful tools available to federal student loan borrowers. The right plan depends on when you borrowed, what types of loans you have, and whether you are pursuing PSLF. For most borrowers with Direct Loans, SAVE (if available) or PAYE will deliver the lowest payments and the clearest path to forgiveness. If you have older FFEL loans, IBR is your best bet. And if you are a parent with PLUS loans, ICR through consolidation is your only IDR option.
No matter which plan you choose, the key is to apply, recertify on time every year, and keep your eye on the forgiveness finish line.
