Discretionary Income Calculator - 2026 Guideline Estimate

A discretionary income calculator estimates how much annual income remains after subtracting a poverty-guideline allowance for your household size and location. Use it when you are checking an income-driven student loan estimate, comparing repayment scenarios, preparing a budget, or explaining why a monthly payment changes after income recertification.

• • Student loan planning: Estimate the income above a selected poverty-guideline allowance before comparing income-driven repayment scenarios.
• • Household budget review: Separate income protected for basic living costs from the amount available for debt, savings, and flexible spending.
• • Income change check: Model a raise, job loss, family-size change, or move to Alaska or Hawaii before sending updated income information.
• • Advisor worksheet: Document the poverty-guideline table, allowance percentage, and payment-rate assumption used in a counseling conversation.

The result is not the same as everyday spending money. In student-loan and public-program language, discretionary income usually means income above a protected benchmark. The benchmark can change by program, household size, location, and year, so the calculator makes those assumptions visible instead of hiding them inside a single payment number.

For student-loan planning, enter the income figure your servicer or worksheet asks for, usually adjusted gross income. For a personal budget, enter the annual income you want to stress-test. Then choose the allowance percentage that matches your scenario. If the result is zero, the discretionary income calculator is showing that your income does not exceed the selected protected amount.

After estimating income above the allowance, use the Student Loan Payment Calculator to compare that payment with a regular amortized loan payment.

The calculator looks up the 2026 HHS poverty guideline, multiplies it by your selected allowance percentage, and subtracts that protected amount from annual income.

• Annual income: The yearly income or AGI used for the scenario.
• Poverty guideline: The 2026 HHS amount for household size and location.
• Allowance percentage: The portion of the guideline protected before income is counted.
• Payment rate: An optional percentage applied to discretionary income for a rough annual and monthly payment estimate.

For household sizes above eight, the calculator starts with the eight-person guideline and adds the official additional-person amount for each extra household member. That matters for larger families because the protected allowance grows by location-specific increments rather than by a flat percentage of income.

The optional payment outputs are included so you can see the size of a percentage-based payment. They do not certify eligibility and do not replace a servicer calculation.

According to HHS ASPE 2026 Poverty Guidelines, the 2026 poverty guideline for one person is $15,960 in the 48 contiguous states and DC, $19,950 in Alaska, and $18,360 in Hawaii.

If your pay is hourly, weekly, or monthly, the Annual Income Calculator can convert it to the annual figure needed here.

These terms explain why two people with the same salary can have different discretionary income results.

The calculator uses current 2026 poverty-guideline values, but it lets you choose the allowance percentage because different worksheets may use different multiples. A 150% setting means one and a half times the guideline is protected. A 100% setting protects only the guideline itself.

Discretionary income is also different from disposable income. Disposable income usually means take-home pay after taxes and payroll deductions. Discretionary income in this context is a formula result tied to a guideline table and a selected allowance.

To see how formula-based discretionary income differs from real monthly cash flow, compare the result with the Budget Calculator.

Enter the assumptions from the worksheet or repayment scenario you are checking, then compare the annual and monthly outputs.

1. 1 Enter annual income: Use adjusted gross income for a student-loan estimate unless your form or servicer asks for a different income measure.
2. 2 Set household size: Enter the family or household count used by the program, not just the number of people with income.
3. 3 Choose location: Select the 48 contiguous states/DC, Alaska, or Hawaii so the calculator uses the correct 2026 table.
4. 4 Pick the allowance: Use 150% when checking an IBR-style formula, 100% for an ICR-style formula, or another percentage only when your worksheet calls for it.
5. 5 Review payment estimate: Choose 0% if you only need discretionary income, or pick a payment percentage to see a rough annual and monthly amount.

If your AGI rises from $60,000 to $66,000 with the same one-person 150% allowance in the 48 states/DC, annual discretionary income rises by $6,000 because the protected income stays $23,940 until the guideline year or household assumptions change.

For a broader federal repayment comparison after this worksheet, review the Student Loan Repayment US Calculator with your loan balance and term assumptions.

A transparent worksheet helps you see which assumption moved the result before you change a repayment or budget decision.

• • Shows the protected amount: You can see the poverty guideline and allowance separately, which makes the subtraction easier to audit.
• • Compares locations: Switching between the 48 states/DC, Alaska, and Hawaii shows whether a location-specific guideline changes the estimate.
• • Supports recertification planning: A borrower can test income or family-size changes before an annual income-driven repayment update.
• • Connects budget and debt views: The monthly discretionary income output can be compared with bills, savings targets, and debt payments.
• • Keeps assumptions visible: The allowance percentage and payment rate remain visible, reducing confusion between income protection and payment calculation.

Use the result as a planning estimate, then compare it with your official statement or servicer calculation. If the two numbers differ, check the income year, household size, spouse-income treatment, poverty-guideline year, and selected repayment formula before assuming one number is wrong.

For household planning, the calculator is most useful when paired with a full budget. Discretionary income can describe a formula result, but it does not show rent, medical costs, childcare, local taxes, or irregular expenses.

When you review the monthly number, compare it with actual room in your checking account, not just with the formula output. A lower payment can still feel tight if insurance premiums, commuting costs, or seasonal bills arrive in the same month.

When lenders or budgets focus on total debt load instead of guideline allowances, the Debt to Income Ratio Calculator gives that separate view.

Small input changes can move the output sharply because the formula subtracts a fixed protected amount before applying any payment percentage.

• • This calculator estimates the arithmetic of income above a selected poverty-guideline allowance; it does not determine eligibility for any repayment plan or benefit.
• • The optional payment output ignores loan balance caps, interest treatment, filing-status rules, servicer processing, and future rule changes.

If your result is close to zero, a small income change or household-size correction can have a large percentage effect on the payment estimate. Keep the income documentation and household-size support you used so you can reconcile the estimate later.

If your loans are involved, verify the current repayment option directly with Federal Student Aid or your servicer. Rules around income-driven repayment have changed in recent years, and a simple discretionary-income worksheet cannot capture every transition rule.

According to Federal Student Aid IDR Plan Request, IBR discretionary income is adjusted gross income above 150% of the poverty guideline amount, while ICR discretionary income is AGI above 100% of the poverty guideline.

According to Consumer Financial Protection Bureau, IBR payments are capped at the lower of a percentage of discretionary income or the 10-year Standard Repayment Plan amount.

If the payment estimate affects a long forgiveness timeline, the Student Loan Forgiveness Calculator can help frame the remaining-balance scenario.
