In this article, we’ll break down how discretionary income is calculated, explore real-world examples, and highlight important considerations to help you make informed decisions about your student loans.

How Is Discretionary Income Calculated?

Discretionary income for student loans is calculated by subtracting a protected amount from your Adjusted 💡 Definition:Your total income before any taxes or deductions are taken out—the starting point for tax calculations.Gross Income💡 Definition:Gross profit is revenue minus the cost of goods sold, reflecting a company's profitability on sales. (AGI💡 Definition:Your total gross income minus specific deductions, used to determine tax liability and eligibility for credits.). This protected amount is based on a percentage💡 Definition:A fraction or ratio expressed as a number out of 100, denoted by the % symbol. of the federal poverty guideline (FPG) for your family size and state of residence. Here’s how it works:

• Income-Driven Repayment Plans (IDR): Plans such as Income-Based Repayment (IBR💡 Definition:An income-driven repayment plan requiring 10-15% of discretionary income with forgiveness after 20-25 years, ideal for borrowers whose debt exceeds their income.), 💡 Definition:An income-driven repayment plan with 10% discretionary income payments, capped at the Standard amount, with forgiveness after 20 years for recent borrowers.Pay💡 Definition:Income is the money you earn, essential for budgeting and financial planning. As You Earn (PAYE), and Revised Pay As You Earn (REPAYE💡 Definition:The newest and most generous federal student loan repayment plan, offering 5-10% payments and interest subsidies for eligible borrowers. or SAVE) use 150% of the FPG to determine your discretionary income.
• Income-Contingent Repayment (ICR💡 Definition:The oldest income-driven plan with 20% discretionary income payments or a 12-year fixed amount, with forgiveness after 25 years—the only IDR option for Parent PLUS loans.): This plan uses 100% of the FPG instead.

Calculation Formula

For most IDR plans: [ \text{Discretionary Income} = \text{AGI} - (1.5 \times \text{Federal Poverty Guideline for family size}) ]

For the ICR plan, the formula is: [ \text{Discretionary Income} = \text{AGI} - (1.0 \times \text{Federal Poverty Guideline for family size}) ]

Monthly Payment Calculation

Once you have your discretionary income, your monthly payment is calculated as a percentage (typically 10% or 15%) of this discretionary income, divided by 12 months.

Real-World Example

Let’s look at a practical example to illustrate these calculations:

• Family Size: 3
• Adjusted Gross Income (AGI): $50,730
• Federal Poverty Guideline (150% for three people): $38,730

Discretionary Income Calculation: [ \text{Discretionary Income} = $50,730 - $38,730 = $12,000 ]

Monthly Payment under IDR (10% of discretionary income): [ ($12,000 \times 0.10) / 12 = $100 \text{ per month} ]

Important Considerations

Family Size and Filing Status

• Family Size: The federal poverty guideline increases with family size, which can lower your discretionary income and result in lower monthly payments.
• Filing Status: For married borrowers, filing jointly means using your combined AGI, potentially increasing payments. Filing separately can use individual AGI but may impact tax benefits.

Upcoming Changes

Starting in July 2026, the Repayment Assistance Plan (RAP) will💡 Definition:A will is a legal document that specifies how your assets should be distributed after your death, ensuring your wishes are honored. introduce significant changes, such as using AGI directly without poverty guideline adjustments and setting a minimum payment💡 Definition:Lowest payment card companies accept—usually 1-3% of balance. Paying only the minimum traps you in debt for decades with massive interest. of $10. This plan extends forgiveness to 30 years, which may affect your repayment strategy.

Exclusions

Remember, discretionary income calculations exclude personal expenses like rent or utilities and are solely based on federal poverty guidelines.

Common Mistakes to Avoid

• Ignoring Family Changes: Any changes in family size or income should prompt a recalculation of your discretionary income, as these factors directly impact your repayment obligations.
• Overlooking State Differences: The federal poverty guideline can vary by state, so ensure you’re using the correct figures for your location.

Bottom Line

Understanding how discretionary income is calculated for student loans is essential for effectively managing your debt. By using a formula based on your AGI and the federal poverty guideline, you can determine your monthly payments under various IDR plans. Consider any changes in your family size or income and stay informed about upcoming repayment plan changes to optimize your repayment strategy. This approach not only helps you keep your payments manageable but also ensures you’re prepared for any shifts in your financial situation.
