Income-Driven Repayment Plans: Complete Student Loan Guide

What Are Income-Driven Repayment (IDR) Plans?

For millions of federal student loan borrowers, standard 10-year repayment plans can create unsustainable monthly bills. Income-Driven Repayment (IDR) plans offer a crucial safety net by tying your monthly payment directly to your income and family size rather than your total loan balance.

Under an IDR plan, if your income drops or you experience financial hardship, your required monthly payment can drop as low as $0 per month without putting your loans into default.

Comparing the 4 Federal IDR Plans (SAVE, PAYE, IBR, ICR)

The U.S. Department of Education offers four main income-driven options for federal Direct and FFEL loans:

1. SAVE Plan (Saving on a Valuable Education)

5%–10% of Discretionary Income

Replaced REPAYE. Protects income up to 225% of the federal poverty line ($0 payments for individuals earning under ~$32,800). Eliminates unpaid monthly interest growth.

2. PAYE Plan (Pay As You Earn)

10% of Discretionary Income

Caps monthly payments at 10% of discretionary income, never exceeding the Standard 10-Year plan amount. Forgiveness achieved after 20 years.

3. IBR Plan (Income-Based Repayment)

10%–15% of Discretionary Income

Available to new and existing borrowers with a partial financial hardship. Forgiveness timeline is 20 or 25 years depending on when loans were disbursed.

4. ICR Plan (Income-Contingent Repayment)

20% of Discretionary Income

The only IDR plan available for Parent PLUS loan borrowers (after consolidating into a Direct Consolidation Loan). Forgiveness after 25 years.

How IDR Monthly Payments Are Calculated

IDR payments are calculated based on your Adjusted Gross Income (AGI) from your tax return minus a set percentage of the Federal Poverty Guideline for your household size.

The Discretionary Income Formula

Discretionary Income = AGI - (Federal Poverty Line × Protection Multiplier). For the SAVE plan, the multiplier protects 225% of the poverty line, keeping more of your income tax-free.

Loan Forgiveness & PSLF Alignment

Any remaining loan balance at the end of your IDR repayment term (20 or 25 years) is completely forgiven by the federal government.

If you work in public service—such as government organizations, public schools, or 501(c)(3) non-profits—enrolling in an IDR plan allows you to qualify for Public Service Loan Forgiveness (PSLF), which forgives your remaining balance completely tax-free after just 10 years (120 qualifying payments).
