Income-Driven Repayment (IDR) Calculator
Estimate monthly student loan payments tied directly to discretionary income and family size.
About Income-Driven Repayment (IDR)
IDR plans cap monthly federal student loan obligations at a set percentage of discretionary income calculated above federal poverty guidelines.
Calculation Logic
Discretionary Income = AGI - (1.5 × Federal Poverty Line)
Standard IDR payments equal 10% of discretionary income divided across 12 calendar months.
