## How Income-Based Repayment Works
IBR caps payments at a percentage of your discretionary income.
### Formula
**Monthly Payment = (Discretionary Income x IBR%) / 12**
Where Discretionary Income = AGI - 150% of Poverty Guideline for your family size.
- New borrowers (after 2014): 10% of discretionary income
- Older borrowers: 15% of discretionary income

Exemple Résolu
Single borrower earning $45,000 with 10% IBR rate.
- Poverty guideline for family of 1 = $15,060
- 150% of poverty = $15,060 x 1.5 = $22,590
- Discretionary income = $45,000 - $22,590 = $22,410
- Monthly payment = round($22,410 x 10% / 12) = round($187) = $187
