Income-Driven Repayment Plans Explained: IBR, PAYE, SAVE, and ICR

What Is Income-Driven Repayment?

Income-driven repayment (IDR) is a set of federal student loan repayment plans that cap your monthly payment based on your income and family size — not your loan balance. After 20–25 years of qualifying payments, any remaining balance is forgiven.

For borrowers whose loan payments would be unaffordable at their income level, IDR plans are one of the most powerful tools in the federal student loan system.

The Four Income-Driven Plans

1. SAVE (Saving on a Valuable Education) — Newest and Most Generous

SAVE replaced REPAYE in 2023 and is currently the most generous IDR plan for most borrowers.

Key features:

• Payments capped at 5% of discretionary income for undergraduate loans (10% for graduate loans, blended for mixed borrowers)
• Discretionary income = income above 225% of the federal poverty line (vs. 150% in other plans)
• No interest accrual if payment covers the monthly interest — your balance cannot grow above the original amount
• Forgiveness after 20 years (undergrad-only borrowers) or 25 years (any graduate loans)
• New: borrowers with original balances under $12,000 may qualify for forgiveness in as few as 10 years

Who it helps most: New graduates with high debt-to-income ratios; anyone whose payment would otherwise not cover monthly interest.

Note: SAVE has faced legal challenges. Check current status at studentaid.gov — the underlying income-driven repayment protections remain intact even if the specific SAVE rules are modified.

2. IBR (Income-Based Repayment) — The Most Widely Available

IBR is available to most federal loan borrowers and comes in two versions:

IBR for new borrowers after July 1, 2014:

• Payments: 10% of discretionary income
• Forgiveness: 20 years
• Partial Financial Hardship (PFH) required

IBR for older borrowers (before July 1, 2014):

• Payments: 15% of discretionary income
• Forgiveness: 25 years
• PFH required

Discretionary income in IBR = income above 150% of the federal poverty line.

IBR is notable because unlike some other IDR plans, it is available to borrowers with both Direct Loans and older FFEL loans.

3. PAYE (Pay As You Earn) — For Newer Borrowers With High Debt

Key features:

• Payments: 10% of discretionary income (income above 150% poverty line)
• Forgiveness: 20 years
• Requires: must be a new borrower as of October 1, 2007 AND have received a disbursement after October 1, 2011

PAYE is often better than old IBR for eligible borrowers because forgiveness comes at 20 instead of 25 years. However, SAVE has largely superseded PAYE for most borrowers due to lower payments and no accrual.

4. ICR (Income-Contingent Repayment) — Least Favorable, But Broadest Eligibility

Key features:

• Payments: lesser of 20% of discretionary income OR what you would pay on a 12-year fixed plan
• Forgiveness: 25 years
• Eligibility: any Direct Loan borrower, including Parent PLUS loans (after consolidating into a Direct Consolidation Loan)

ICR is generally the least favorable plan, but it is the only IDR option for Parent PLUS borrowers (after consolidation) and some other loan types.

Side-by-Side Comparison

How Monthly Payments Are Calculated

Step 1: Find your Adjusted Gross Income (AGI) — from your tax return.

Step 2: Calculate the applicable poverty line for your family size. The 2025 federal poverty line for a family of one is $15,060.

Step 3: For SAVE: multiply poverty line by 2.25 (225%) = $33,885. Subtract from your AGI.

Step 4: Multiply the result by 5% (undergraduate) or 10% (graduate), then divide by 12.

Example: AGI = $48,000, family size 1, SAVE (all undergrad loans):

• Poverty line: $15,060 × 2.25 = $33,885
• Discretionary income: $48,000 − $33,885 = $14,115
• Annual payment: $14,115 × 5% = $705.75
• Monthly payment: $705.75 ÷ 12 = $58.81/month

On a $35,000 loan, the standard 10-year payment would be $397/month. SAVE reduces that to $59/month.

The Critical Trade-Off: Longer Timeline, More Total Interest

IDR plans keep monthly payments low — but the longer you pay, the more interest accumulates. Over 20 years, you will pay significantly more interest than on a standard 10-year plan.

However: if your balance is forgiven at the end of IDR, that calculation flips. Borrowers with high debt-to-income ratios often pay less in total on IDR + forgiveness than on the standard plan.

Use the Student Loan Calculator to compare total cost under different plans.

IDR and Taxes on Forgiveness

Balances forgiven through standard IDR plans (not PSLF) have historically been taxable as income in the year of forgiveness. For example, a $60,000 forgiven balance could trigger a $15,000–$20,000 tax bill.

Current status: The American Rescue Plan made IDR forgiveness tax-free through 2025. Legislation extending this is being debated — check current tax treatment with a tax advisor before making long-term decisions based on forgiveness.

PSLF forgiveness has always been tax-free with no planned changes.

Enrolling in an IDR Plan

1. Go to studentaid.gov and log in
2. Navigate to "Repayment Plans" → "Income-Driven Repayment"
3. Apply online (income verified via IRS data transfer or manual upload)
4. Recertify income and family size every year — missing recertification resets you to the standard plan temporarily

Frequently Asked Questions

Does IDR hurt my credit score? No. Enrolling in an income-driven repayment plan does not negatively impact your credit score. Making on-time IDR payments builds positive payment history.

Can I switch IDR plans? Yes. You can switch between IDR plans at any time, though switching may reset your forgiveness timeline in some cases. Consult studentaid.gov before switching if you are close to forgiveness.

What if I have both federal and private loans? IDR plans apply only to federal loans. Private loans require separate payment arrangements. The two payments are independent.

Does my spouse's income count? On most IDR plans, if you file taxes jointly, your spouse's income is included. If you file separately, only your income is counted. This matters most when one spouse has significantly higher income — some couples file separately specifically to keep IDR payments low.
