Choose the value to solve for, then provide the remaining balance, term, rate, or monthly payment as applicable.
Worked example
With a balance, rate, and term, the calculator estimates the required monthly payment.
Understanding your result
The answer helps compare repayment scenarios.
- Forgiveness, income-driven plans, and fees are not modelled.
- Double-check values and units before calculating.
Student-loan results are estimates and do not account for income-driven repayment, forgiveness, or loan-servicer rules.
Frequently asked questions
What does this student loan calculator do?
Solve for a student-loan payment, balance, term, or interest rate.
How do I use this student loan calculator?
Choose the value to solve for and enter the remaining three values.
What does the result mean?
The answer helps compare repayment scenarios.
What should I check before relying on it?
Forgiveness, income-driven plans, and fees are not modelled.
What happens if I try to solve for the term but the payment is too low?
If the monthly payment doesn't cover the monthly interest, the balance would never shrink, so there's no valid term — the calculator asks for a higher payment or lower rate instead.
Does this factor in income-driven repayment or forgiveness programs?
No — it models a standard fixed-payment loan. Income-driven repayment, forgiveness, and grace periods follow different rules than the standard amortization formula used here.
