Income-Driven Repayment Estimator

Estimate your monthly federal student loan payment under the four main Income-Driven Repayment (IDR) plans: SAVE, PAYE, IBR (new & old), and ICR.

Adjusted Gross Income (AGI) — annual ($)

Family Size

State of Residence

Contiguous 48 states / D.C. (default) Alaska Hawaii

Total Federal Loan Balance ($)

Weighted Average Interest Rate (%)

New borrower on or after July 1, 2014?

⚠️ Negative amortization means your payment does not cover monthly interest; your balance may grow. SAVE plan has interest subsidy that prevents balance growth for qualifying borrowers. Forgiven amounts may be taxable income (except PSLF). Consult your loan servicer for exact figures.

#### Formulas Used

Federal Poverty Level (2024, contiguous US): FPL = $15,060 + $5,380 × (family_size − 1)

Discretionary Income: SAVE: max(0, AGI − 2.25 × FPL) PAYE / IBR New: max(0, AGI − 1.50 × FPL) IBR Old: max(0, AGI − 1.50 × FPL) ICR: max(0, AGI − 1.00 × FPL)

Monthly Payment: SAVE = DiscretionarySAVE × 10% ÷ 12 PAYE = min(Discretionary150 × 10% ÷ 12, Standard 10-yr payment) IBR New = min(Discretionary150 × 10% ÷ 12, Standard 10-yr payment) IBR Old = min(Discretionary150 × 15% ÷ 12, Standard 10-yr payment) ICR = min(Discretionary100 × 20% ÷ 12, Standard 12-yr payment)

Standard N-Year Payment: PMT = P × [r(1+r)n] / [(1+r)n − 1]   where r = annual rate ÷ 12, n = months
