This tool allows you to estimate your monthly payment and total repayment amount based on your income, chosen repayment percentage, and repayment period.
Income Based Student Loan Calculator
What is an Income-Based Student Loan Calculator?
An Income-Based Student Loan Calculator is a free online tool that helps borrowers estimate their repayment amounts under an income-driven repayment plan. Instead of a fixed monthly installment, payments are calculated as a percentage of your income, spread across a set number of months.
This approach ensures your student loan payments remain manageable and aligned with your earnings.
How to Use the Income-Based Student Loan Calculator
Using the calculator is simple and requires only three inputs:
- Annual Income:
Enter your yearly income before taxes. This forms the basis for your repayment calculation. - Payment Percentage (% of Income):
Specify the percentage of your income you can allocate to loan payments. Common ranges are 10%–15% for income-driven plans. - Repayment Period (Months):
Decide how long you want to spread your repayment. Typical repayment plans range from 120 months (10 years) to 300+ months.
Once you enter these values, click Calculate. The tool will instantly show:
- Your Monthly Payment
- Your Total Paid over the entire repayment period
You can reset the values anytime using the Reset button.
Example Calculation
Let’s look at a practical example:
- Annual Income: $48,000
- Payment Percentage: 10%
- Repayment Period: 120 months (10 years)
Step 1: Calculate Annual Payment
Annual Payment = $48,000 × (10 ÷ 100) = $4,800
Step 2: Monthly Payment
$4,800 ÷ 12 = $400 per month
Step 3: Total Paid Over 120 Months
$400 × 120 = $48,000
In this example, you’ll pay $400 per month for 10 years, totaling $48,000.
