Discretionary income is money you have left after you pay for essentials, like housing, food and taxes. This portion of your income goes toward "discretionary" wants, like entertainment and travel.
The federal government uses a discretionary income formula to set your student loan repayment amounts under income-driven repayment programs. This could change, though, with proposed legislation.

Fixed APR
2.89% - 17.49%Lowest rates shown include the auto debit discount. Advertised APRs for undergraduate students assume a $10,000 loan to a student who attends school for 4 years and has no prior Sallie Mae-serviced loans. Interest rates for variable rate loans may increase or decrease over the life of the loan based on changes to the 30-day Average Secured Overnight Financing Rate (SOFR) rounded up to the nearest one-eighth of one percent. Advertised variable rates are the starting range of rates and may vary outside of that range over the life of the loan. Interest is charged starting when funds are sent to the school. With the Fixed and Deferred Repayment Options, the interest rate is higher than with the Interest Repayment Option and Unpaid Interest is added to the loan’s Current Principal at the end of the grace/separation period. To receive a 0.25 percentage point interest rate discount, the borrower or cosigner must enroll in auto debit through Sallie Mae. The discount applies only during active repayment for as long as the Current Amount Due or Designated Amount is successfully withdrawn from the authorized bank account each month. It may be suspended during forbearance or deferment. Advertised APRs are valid as of 10/27/2025. Loan amounts: For applications submitted directly to Sallie Mae, loan amount cannot exceed the cost of attendance less financial aid received, as certified by the school. Applications submitted to Sallie Mae through a partner website will be subject to a lower maximum loan request amount. Miscellaneous personal expenses (such as a laptop) may be included in the cost of attendance for students enrolled at least half-time. Examples of typical costs for a $10,000 Smart Option Student Loan with the most common fixed rate, fixed repayment option, 6-month separation period, and two disbursements: For a borrower with no prior loans and a 4-year in-school period, it works out to a 10.28% fixed APR, 51 payments of $25.00, 119 payments of $182.67 and one payment of $121.71, for a Total Loan Cost of $23,134.44. For a borrower with $20,000 in prior loans and a 2-year in-school period, it works out to a 10.78% fixed APR, 27 payments of $25.00, 179 payments of $132.53 and one payment of $40.35 for a total loan cost of $24,438.22. Loans that are subject to a $50 minimum principal and interest payment amount may receive a loan term that is less than 10 years. A variable APR may increase over the life of the loan. A fixed APR will not.

The variable rate is based on the rate published on the 25th day, or the next business day, of the preceding calendar month, rounded to the nearest hundredth of a percent. The rate will not increase more than once a month, but there is no limit on the amount that the rate could increase at one time. Please note, we are not able to offer variable rate loans in AK, IL, MN, NH, OH, TN, and TX. Our lowest rates are only available for our most credit qualified borrowers and require selection of our shortest term offered (5 years) and enrollment in our .25% auto pay discount from a checking or savings account.

For federal loans, the U.S. Department of Education uses a discretionary income total to determine your monthly bill for income-driven repayment plans. These plans can help lower your payment if you’re struggling to repay.
Discretionary income for income-driven repayment plans is calculated using the difference between your yearly adjusted gross income, or AGI, and the poverty line for your family size and state.
The percentage of income above the poverty line for the Income-Contingent Repayment plan is 100%, while Income-Based and Pay As You Earn repayment plans are 150%.
You can find your AGI on your most recent tax return. For 2025, it’s located on line 11 of IRS Form 1040.
Income-driven repayment plans cap your monthly payment from 10% to 20% of your discretionary income. Use a discretionary income calculator to see what your payments could look like — including a $0 payment if your AGI is low enough.
How discretionary income can change
Borrowers on income-driven repayment plans are required to recertify annually. This means you inform the Education Department of any changes to your family size or income so that your repayment amount may be recalculated.
Moving, getting married or receiving a pay increase can all impact your discretionary income amount. Even if you have no changes to income or family size, you must still recertify.
Changes to student loan repayment programs
President Donald Trump’s “one big, beautiful bill” could alter the current parameters of income-driven repayment plans. The bill proposes a new Repayment Assistance Plan (RAP) that would eliminate the use of discretionary income in calculating student loan repayment amounts. Instead, RAP would use gross income, rather than discretionary income, to determine payments.
Discretionary income for budgeting
Building a budget typically involves listing out your income and expenses and creating a spending-and-savings plan around your discretionary income.
First, you need to understand which expenses are essential, or nondiscretionary, to ensure you cover those each month. These usually include housing, utilities, groceries, gas and other fixed bills. Then, you can divide what you have left over — your discretionary income — based on a budgeting method.
Some budgeting methods to consider include the 50/30/20 budget, envelope system, pay yourself first or zero-based budget.
