Income-Driven Repayment (IDR) plans are designed to make student loan payments more manageable based on a borrower's income and family size. These plans cap monthly payments at a percentage of discretionary income, which can significantly lower the amount owed each month compared to standard repayment plans. Under IDR, borrowers may also qualify for loan forgiveness after making payments for a set number of years, typically 20 to 25 years. This option is particularly beneficial for those with lower incomes or financial hardships, allowing them to avoid default and maintain financial stability while repaying their federal student loans.
