What Is an Income-Based Student Loan Repayment Plan?
An income-based repayment (IBR) plan adjusts your monthly student loan payment according to your income and family size. Rather than a fixed payment, your repayment is tied to discretionary income, allowing flexibility during periods of lower earnings.
Key features of income-based plans include:
- Monthly payments aligned with your earnings
- Possible forgiveness after a set number of years (e.g., 20–25 years)
- Financial relief for borrowers with high debt relative to income
These plans are particularly helpful for recent graduates, parents, or those managing multiple financial responsibilities.
How the Income-Based Student Loan Calculator Works
The calculator estimates your monthly payment using a simplified formula based on discretionary income:Monthly Payment=12Discretionary Income×(Plan %)
Where discretionary income is calculated as:Discretionary Income=Annual Income−1.5×Poverty Guideline for Family Size
- Annual Income: Your pre-tax yearly earnings
- Family Size: Number of people in your household
- Plan %: Percentage of discretionary income applied toward loan repayment
The calculator automatically adjusts for family size, helping you determine what portion of your income is considered discretionary.

Example Calculation
Let’s assume:
- Annual Income: $45,000
- Family Size: 3
- Loan Balance: $35,000
- Plan Percentage: 10%
Discretionary income calculation:Poverty Guideline=13890+(3−1)×4820=23,530 Discretionary Income=45,000−1.5×23,530=8,205
Monthly Payment:Monthly Payment=128,205×0.10=$68.38
This borrower would pay approximately $68.38 per month under this plan.
