Income-Driven Repayment Calculator
Estimate your monthly federal student loan payment under IBR, PAYE, or ICR from your AGI, family size, and the federal poverty guideline.
Income-Driven Repayment Plan Formulas
The calculator uses 2026 HHS poverty guidelines for the 48 contiguous states and DC. Alaska and Hawaii are not modeled. Federal repayment rules can change, so verify your official loan-servicer estimate.
| Plan | Income formula | Poverty-guideline multiplier | Other modeled limit |
|---|---|---|---|
| PAYE | 10% of discretionary income | 150% | Capped at the standard 10-year payment |
| New IBR | 10% of discretionary income | 150% | Capped at the standard 10-year payment |
| Old IBR | 15% of discretionary income | 150% | Capped at the standard 10-year payment |
| ICR | 20% of discretionary income | 100% | Uses the lower income-adjusted 12-year amount when applicable |
Frequently Asked Questions about the Income-Driven Repayment Calculator
How is the income-driven repayment amount calculated?
For IBR and PAYE, the calculator subtracts 150% of the poverty guideline from AGI and applies the plan's 10% or 15% rate. For ICR, it subtracts 100%, calculates 20% of the remainder, and compares that result with an income-adjusted 12-year payment. It uses the lower ICR amount. This remains a simplified estimate and does not reproduce every servicer calculation or program rule.
What counts as discretionary income?
In this calculator, IBR and PAYE protect 150% of the poverty guideline, while ICR protects 100%. The built-in values are the 2026 guidelines for the 48 contiguous states and DC; Alaska, Hawaii, later guideline years, and other program changes are not modeled. Any negative result is treated as zero.
Which plans does this cover, and how do they differ?
The tool models simplified PAYE, new IBR, old IBR, and ICR. For ICR, it includes the income-adjusted 12-year comparison, using the selected single or married-or-head category. It does not model the Repayment Assistance Plan, SAVE, current enrollment eligibility, loan-type restrictions, spousal-income rules, or every program rule. Check StudentAid.gov and your servicer for the plans currently available to your loans.
Why does the calculator ask for my loan balance and interest rate?
IBR and PAYE limit your monthly payment to the amount you would pay on the standard 10-year plan, so the calculator needs your balance and interest rate to compute that ceiling. It amortizes your balance over 120 months at your rate and uses the lower of that figure and the income-driven amount. For ICR, the balance and rate are used in the income-adjusted 12-year comparison, so they can change the modeled payment.
Is this the exact payment my loan servicer will set?
No. It uses 2026 poverty guidelines and simplified plan formulas. It does not determine eligibility or model every loan type, spouse-income rule, recertification date, interest rule, or current federal repayment option. Confirm any payment with StudentAid.gov and the loan servicer.
What if my calculated payment comes out to $0?
A $0 estimate means AGI did not exceed the protected amount under the selected simplified formula. Whether a month counts toward a particular discharge or forgiveness program depends on current enrollment, loan status, plan, and program rules. Confirm the account record with the servicer.
