Managing student loans can feel overwhelming, especially when your income is tight. The Income-Based Repayment (IBR) Calculator helps you take control of your loan payments by estimating how much you’ll owe each month based on your income, family size, and repayment plan. This simple online tool provides quick, accurate results and helps you plan your financial future with confidence.

What Is the Income-Based Repayment Calculator?

The Income-Based Repayment Calculator is an interactive tool designed to estimate your monthly student loan payment under different federal income-driven repayment (IDR) plans. It helps you determine:

• Your estimated monthly and annual payments
• The total amount paid over 20 years
• Your potential loan forgiveness after the repayment period

By using this calculator, borrowers can understand how their income, family size, and repayment plan impact their long-term loan costs.

How to Use the Income-Based Repayment Calculator (Step-by-Step)

Follow these simple steps to calculate your student loan payments:

Step 1: Enter Your Annual Income

In the “Annual Income” field, type your total yearly income before taxes. This value determines how much of your income is considered “discretionary.”

Step 2: Add Your Family Size

Enter the number of people in your household. Family size directly affects your eligibility for lower payments under income-driven repayment plans.

Step 3: Input Your Total Loan Balance

Type your total outstanding student loan balance. The calculator uses this to estimate interest and total repayment.

Step 4: Include Your Interest Rate

Add your annual interest rate as a percentage (e.g., 5 for 5%). This helps calculate how much interest you’ll pay over time.

Step 5: Select a Repayment Plan

Choose between:

• 10% of discretionary income (Standard IBR Plan)
• 15% of discretionary income (Revised IBR Plan)

Step 6: Click “Calculate”

Once you click the Calculate button, a progress bar will appear, showing that your results are being processed. After 3 seconds, your estimated results will appear automatically.

Step 7: View and Save Results

Your repayment summary will display the:

• Monthly payment amount
• Annual payment total
• Total paid over 20 years
• Estimated loan forgiveness amount

You can also copy or share the result with a single click.

Example Calculation

Let’s look at a practical example:

• Annual Income: $45,000
• Family Size: 2
• Total Loan Balance: $60,000
• Interest Rate: 5%
• Repayment Plan: 10% (Standard IBR)

After entering these values and clicking Calculate, the tool might show:

• Estimated Monthly Payment: $210.50
• Annual Payment: $2,526.00
• Total Paid Over 20 Years: $50,520.00
• Estimated Loan Forgiveness: $25,000.00

This means you’d pay about $210 per month, and after 20 years, the remaining balance may qualify for forgiveness under federal rules.
