Income-based repayment or income-driven-repayment (IDR) is a student loan repayment program in the United States that regulates the amount that one needs to pay each month based on one's current income and family size. The phrase is an umbrella term for four specific repayment plans that are available within the William D. Ford Federal Direct Loan Program (FDLP, FDSLP, and Direct Loan) and the Federal Family Education Loan Program (FFEL). All these four repayment plans are also named as Income-Based Repayment (IBR), Pay As You Earn (PAYE), Revised Pay As You Earn (REPAYE), and Income-Contingent Repayment (ICR). Mechanics Payments under the IBR Plan are 10% or 15% of discretionary income but never exceed the 10-year standard repayment amount. Whether a borrower pays 10% or 15% of discretionary income depends on when the borrower first started borrowing student loans. 10% of the borrower's discretionary income if they borrowed on or after July 1, 2014 15% of the borrower's discretionary income if they did not borrow on or after July 1, 2014 Payments under the PAYE Plan are 10% of discretionary income but will never be more than the 10-year standard repayment amount. Payments under the REPAYE Plan are also 10% of discretionary income; however, unlike IBR and PAYE, payments for high-income borrowers may be higher than the 10-year standard repayment amount. Also, unlike IBR and PAYE, if required monthly payments do not cover the accruing interest, 50% of the unpaid interest is forgiven, thereby reducing negative amortization. Payments under the ICR Plan are the lesser of 20% of discretionary income or a 12-year standard repayment amount adjusted based on the borrower's income. Eligibility Eligibility requirements for the income-driven repayment plans depend on which plan the borrower chooses and when the student borrowed. The ICR Plan has the fewest eligibility requirements. A borrower is only required to have an eligible loan. The IBR and Pay As You Earn Plans require that the borrower demonstrate a "need" to make income-driven payments and have eligible loans. The Pay As You Earn Plan is limited to those who borrowed recently. Specifically, the borrower must be a "new borrower" as of October 1, 2007, and have received a disbursement of a Direct Loan on or after October 1, 2011. A borrower is a "new borrower" if, when receiving a federal student loan on or after October 1 2007, the borrower did not have an outstanding balance
