Estimated Monthly Payment
What is an Income-Driven Repayment (IDR) Plan?
IDR plans are federal student loan programs that calculate your monthly payment based on your discretionary income rather than the total loan balance. These plans are especially useful for:
- Recent graduates with lower incomes
- Families with multiple dependents
- Borrowers managing multiple loans
IDR plans cap your payments to a percentage of your income above the federal poverty level and may forgive remaining debt after 20–25 years of qualifying payments.
How the Student Loan IDR Calculator Works
The calculator estimates your monthly payment using the formula:Monthly Payment=12Discretionary Income×10%
Where Discretionary Income is:Discretionary Income=Annual Income−(Poverty Guideline×Family Size)
This ensures your monthly payment is proportional to your ability to pay while considering household size and federal poverty levels.
How to Use the Calculator
Using the Student Loan IDR Calculator is simple and intuitive. Here’s a step-by-step guide:
Step 1: Enter Your Loan Balance

Example: $50,000
Step 3: Enter Your Family Size
Include yourself, spouse, and dependents.
Example: 1 (just you)
Step 4: Enter Poverty Guideline

Example Calculation
Let’s assume:
- Loan Balance: $35,000
- Annual Income: $50,000
- Family Size: 1
- Poverty Guideline: $13,890
Discretionary Income:
$50,000 − $13,890 = $36,110
Monthly Payment:
10% of $36,110 ÷ 12 = $301 per month
This means your student loan payment under an IDR plan would be approximately $301/month.

Understanding Discretionary Income
Discretionary income is the portion of income considered “extra” after accounting for basic living needs based on federal poverty guidelines. IDR plans use this calculation to ensure affordable monthly payments:
- Single person: income − poverty guideline
- Family of 4: income − (poverty guideline × 4)
Your monthly payment increases if your income rises or your family size decreases.
