What Is an IDR Payment Calculator?

An IDR Payment Calculator determines monthly payments under federal income-driven repayment plans, including IBR, PAYE, and REPAYE. It helps borrowers see how their income affects monthly payments and assess eligibility for long-term loan forgiveness.

Key Uses:

• Compare repayment options
• Budget effectively for loan payments
• Understand potential forgiveness eligibility

Essential Inputs

1. Loan Balance: Total federal student loan amount
2. Annual Income: Gross yearly income
3. Family Size: Household members for calculation
4. State of Residence (optional): For poverty guideline reference

Expected Outputs

• Estimated Monthly Payment based on income
• Repayment Term (20–25 years under IDR)

Calculation Formula

IDR monthly payment:$$\text{Monthly Payment} = \frac{\text{Discretionary Income} \times \text{Percentage (10–15\%)}}{12}$$Monthly Payment=12Discretionary Income×Percentage (10–15%)​

Discretionary income is calculated as:$$\text{Discretionary Income} = \text{Adjusted Gross Income} - (150\% \text{ of Poverty Guideline})$$Discretionary Income=Adjusted Gross Income−(150% of Poverty Guideline)

Example:

• Annual Income: $40,000
• Family Size: 1
• 150% Poverty Guideline: $20,385

$$\text{Discretionary Income} = 40,000 - 20,385 = 19,615$$Discretionary Income=40,000−20,385=19,615 $$\text{Monthly Payment} = 19,615 \times 10\% ÷ 12 \approx 163.46$$Monthly Payment=19,615×10%÷12≈163.46

How to Use the Calculator

1. Enter your loan balance and annual income.
