1. What is Income-Based Repayment (IBR)?

Income-Based Repayment (IBR) is a federal student loan repayment plan that caps your monthly payment at a percentage of your discretionary income. It's designed to make repayment more manageable for borrowers with lower incomes relative to their student loan debt.

2. How Does the Calculator Work?

The calculator uses the IBR formula:

\[ PMT = \min\left(P \times \frac{r (1 + r)^n}{(1 + r)^n - 1}, \text{income} \times \text{percentage}\right) \]

Where:

\( P \) — Loan principal amount
\( r \) — Monthly interest rate (annual rate ÷ 12)
\( n \) — Total number of payments (loan term in months)
\( income \) — Annual income
\( percentage \) — IBR percentage (typically 10% or 15%)

Explanation: The calculator compares your standard loan payment with your income-based payment and selects the lower amount.

3. Importance of IBR Calculation

Details: Calculating your potential IBR payment helps you understand repayment options, budget effectively, and determine if you qualify for loan forgiveness programs.

4. Using the Calculator

Tips: Enter your total loan amount, monthly interest rate (divide APR by 12), repayment term in months, annual income, and IBR percentage (typically 0.10 or 0.15).

5. Frequently Asked Questions (FAQ)

Q1: Who qualifies for IBR?
A: Federal student loan borrowers with a partial financial hardship (when IBR payment is lower than standard payment).

Q2: What's the difference between IBR and PAYE?
A: PAYE (Pay As You Earn) typically uses 10% of discretionary income versus IBR's 15%, and has different eligibility requirements.

Q3: How is discretionary income calculated?
A: For IBR, it's typically your AGI minus 150% of the poverty guideline for your family size and state.

Q4: Are there loan forgiveness options with IBR?
A: Yes, remaining balance may be forgiven after 20-25 years of qualifying payments (depending on when loans were taken out).

Q5: Does this calculator work for private loans?
A: No, IBR is only available for federal student loans. Private loans have different repayment options.
