About student loan repayment

Standard student-loan repayment spreads the balance over equal monthly payments, often across ten years. Extending the term lowers the monthly payment but adds interest; paying extra each month clears the balance faster and cheaper. This calculator shows both the monthly and total cost so you can plan.

Frequently Asked Questions

Does this model income-driven repayment?

No — it models a standard fixed repayment plan. Income-driven plans adjust payments to your earnings and follow different rules.

How can I pay less interest?

A shorter term or extra monthly payments both reduce total interest. Even small overpayments add up over a ten-year loan.

Is this calculator free and private?

Yes. It's completely free with no signup, and every calculation runs locally in your browser, so your numbers never leave your device.
