IBR payment calculator
Estimate your Income-Based Repayment payment and discretionary income.
Income-Based Repayment (IBR) is 10% of discretionary income for new borrowers (or 15% for borrowers from before July 1, 2014). Discretionary income is your AGI minus 150% of the HHS poverty guideline for your family size and region. The tool below shows each step. The real payment is also capped at the 10-year Standard amount, and is $0 when income is at or below 150% of the guideline. Estimate only, not advice.

Frequently asked questions
How is the IBR payment calculated?
IBR is 10% of discretionary income for new borrowers (first loan on/after July 1, 2014) or 15% for older borrowers. Discretionary income is your AGI minus 150% of the HHS poverty guideline for your family size and region. The payment is also capped at the 10-year Standard amount, and is $0 when your income is at or below 150% of the guideline.
Can new borrowers use IBR?
No. IBR is closed to borrowers whose first loan is on or after July 1, 2026; they use the Repayment Assistance Plan (RAP) instead. IBR remains permanently available to borrowers whose first loan is before July 1, 2026.
What poverty guideline does this use?
It uses the 2025 HHS Poverty Guidelines. In practice your servicer applies the guideline in effect when you apply or recertify, which may differ slightly. Verify your figure at studentaid.gov.
