How it works

The Income-Driven Repayment Calculator helps you estimate your monthly payments and potential loan forgiveness under various income-driven repayment plans. This method considers your loan balance, income, family size, and interest rate to determine your payment amounts. For example, if you have a student loan balance of $80,000, an annual income of $55,000, a family size of 1, and an interest rate of 5.5%, the calculator will apply the formula used in the SAVE plan. This plan caps your monthly payments at 10% of your discretionary income, which is calculated as your income minus 150% of the poverty line. Based on these inputs, your monthly payment under the SAVE plan would be approximately $350. Over 20 years, if you remain eligible, a significant portion of your loan may be forgiven after making consistent payments. The tool also compares this with the standard 10-year repayment plan, showing the total forgiven amount at the end of the term, helping you make informed financial decisions regarding your student loans.

Tips

  • Keep your income documentation updated to ensure accurate calculations.
  • Consider increasing your family size input if you're planning to have dependents, as this can lower your monthly payment.
  • Regularly review your income-driven repayment options as your financial situation changes.
  • Use the calculator annually to track your progress towards forgiveness and adjust your plan if necessary.
