Managing federal student loans can feel overwhelming, especially with varying income levels and family sizes. The IDR (Income-Driven Repayment) Payment Calculator helps borrowers estimate their monthly payments under federal IDR plans such as IBR, PAYE, REPAYE, and ICR.
With this tool, borrowers can plan their finances, avoid default, and maintain affordable payments while working toward loan forgiveness.
What Is an IDR Payment Calculator?
An IDR Payment Calculator is an online tool that calculates your estimated monthly payments based on:
- Federal student loan balance
- Adjusted gross income (AGI)
- Family size
- IDR plan type (IBR, PAYE, REPAYE, or ICR)
The calculator helps:
- Estimate monthly payments

Why Use an IDR Payment Calculator?
The IDR Payment Calculator provides multiple benefits:
