Learn How Income-Driven Repayment Plans Work

What Income-Driven Repayment Plans Are and How They Work

Income-driven repayment plans are federal student loan repayment programs that set your monthly payment amount based on your current income and family size rather than how much you borrowed. Instead of paying a standard fixed amount each month, your payment adjusts according to what you actually earn. The U.S. Department of Education oversees these plans, and they apply to most federal student loans, including Direct Subsidized Loans, Direct Unloans, and Direct PLUS Loans taken out by students (but not parent PLUS Loans).

The basic mechanics work like this: You report your current income and family size to your loan servicer. Using a formula set by federal law, the servicer calculates what portion of your discretionary income should go toward your student loan payment each month. Discretionary income is your adjusted gross income minus 150 percent of the federal poverty line for your family size. If your income falls below the poverty line, your monthly payment may be as low as zero dollars, though your loan will continue to accrue interest.

Four main income-driven plans currently exist: Income-Based Repayment (IBR), Pay As You Earn (PAYE), Revised Pay As You Earn (REPAYE), and Income-Contingent Repayment (ICR). Each has slightly different payment formulas and rules about who can use them. The plans were created to provide relief for borrowers whose loan balances grew large relative to their incomes, particularly those pursuing careers in lower-paying fields or facing temporary income reductions.

One practical takeaway: Income-driven plans can be useful when your monthly income is low compared to your loan balance. However, they typically extend your repayment timeline and may result in paying more interest over the life of the loan. Understanding which plan fits your situation requires looking at your specific numbers.

Understanding the Four Income-Driven Repayment Plans

Income-Based Repayment (IBR) calculates your monthly payment as 10 percent or 15 percent of your discretionary income, depending on when you took out your loans. If you borrowed before July 1, 2014, your payment is 15 percent of discretionary income. If you borrowed on or after July 1, 2014, your payment is 10 percent. Under IBR, if you have remaining loan balance after 20 or 25 years of payments (depending on your loan date), the remaining balance may be forgiven, though you would owe taxes on the forgiven amount as ordinary income.

Pay As You Earn (PAYE) sets your monthly payment at 10 percent of your discretionary income and offers forgiveness after 20 years of payments. PAYE is generally the most favorable option for recent borrowers because of the lower percentage and shorter forgiveness timeline. However, PAYE has income restrictions—you must be a new borrower as of October 1, 2007, and have received a disbursement after October 1, 2011, to use this plan.

Revised Pay As You Earn (REPAYE) is available to nearly all borrowers and also calculates payments at 10 percent of discretionary income. The key difference is that REPAYE offers forgiveness after 20 years for undergraduate loans and 25 years for graduate loans. REPAYE can be particularly useful for borrowers who don't meet PAYE's restrictions. One important consideration: Under REPAYE, married borrowers filing jointly must include their spouse's income in the calculation, even if the spouse has no federal student loans.

Income-Contingent Repayment (ICR) calculates your payment as the lesser of two amounts: either 20 percent of your discretionary income, or what you would pay under a 12-year standard repayment plan adjusted for your income. ICR offers forgiveness after 25 years. This plan is often less favorable than the others because the payment percentage is higher, but it serves as a safety net for borrowers who don't qualify for other income-driven options, including those with Parent PLUS Loans (which cannot be discharged under other income-driven plans).

Practical takeaway: Comparing these four plans requires calculating what your actual monthly payment would be under each based on your income and family size. The lowest payment percentage doesn't always mean the lowest overall payment—your discretionary income calculation matters too. Consider creating a simple spreadsheet showing your estimated monthly payment under each plan to see which produces the lowest amount you'd pay monthly.

How Discretionary Income Calculations Work

Discretionary income is the foundation of income-driven payment calculations, and understanding how it's determined is crucial for knowing what your payment will be. The formula is: your Adjusted Gross Income (AGI) from your federal income tax return minus 150 percent of the federal poverty line for your family size and state of residence.

To illustrate with a concrete example: Suppose you filed your most recent tax return as a single person with an AGI of $35,000. In 2024, the federal poverty line for a single person is $14,580. Multiplying by 150 percent gives $21,870. Your discretionary income would be $35,000 minus $21,870, which equals $13,130. If you're on a plan with 10 percent of discretionary income, your payment would be $1,313 per year, or roughly $109 per month.

The poverty line thresholds vary by family size. For a family of four in 2024, the poverty line is $30,000, making 150 percent of that $45,000. A married couple filing jointly with a combined AGI of $60,000 would have discretionary income of $15,000, resulting in a 10 percent payment of about $125 monthly. The larger your family size, the higher the poverty line threshold, which can meaningfully reduce your discretionary income calculation and therefore your monthly payment.

Your income changes from year to year, so you need to recertify your income-driven plan annually. Most borrowers provide their most recent tax return information. However, if your current income has dropped significantly since you filed your taxes, you can submit more recent pay stubs or documentation to show a lower current income. Some borrowers in temporary hardship may have zero income and thus zero monthly payments under an income-driven plan, though interest continues to accrue on unsubsidized loans.

Practical takeaway: Review your last federal tax return before determining which income-driven plan to choose. Calculate your actual discretionary income using the formula above, then multiply by the percentage your chosen plan uses to see your estimated monthly payment. Keep in mind that major life changes—job loss, reduced hours, marriage, adding children—significantly affect this calculation.

Loan Forgiveness and Tax Implications

One of the primary reasons borrowers choose income-driven plans is the possibility of loan forgiveness. After making payments for a set number of years—typically 20 to 25 years depending on the plan—any remaining loan balance can be forgiven. This means you would no longer owe the debt to the federal government. However, there's a critical caveat: the forgiven amount is treated as ordinary income for federal tax purposes, and you would owe income taxes on that amount.

Consider this example: You owe $80,000 in federal student loans and enter an income-driven plan. Over 20 years, you make consistent monthly payments totaling $60,000. At the end of those 20 years, $20,000 remains. That $20,000 is forgiven—meaning you no longer owe it—but you would receive a 1099-C form from the Department of Education treating that $20,000 as taxable income. If your tax bracket is 22 percent, you would owe approximately $4,400 in federal income taxes on that forgiven amount, though state taxes may apply as well.

This tax liability can be substantial. Some borrowers use income-driven plans expecting forgiveness, only to face an unexpected large tax bill in the forgiveness year. Financial planners sometimes recommend setting aside money during the repayment period to cover the projected tax liability, or exploring whether you might file as uncollectible with the IRS in the forgiveness year if your income is still very low. However, tax situations are individual, and speaking with a tax professional before reaching forgiveness is advisable.

It's also important to note that loan forgiveness is not guaranteed. The programs have existed for less than 20 years in their current form, so relatively few borrowers have
