Student Loan Calculator

Estimate monthly student loan payments, total interest, and payoff time.

Formula & Methodology

Monthly payment M = P × [r(1+r)^n] / [(1+r)^n − 1] for principal P, monthly rate r, and term n months.

Worked Example

A $35,000 student loan at 6.8% on a 10-year term costs about $403/month.

Frequently Asked Questions

What repayment plans exist?

Standard plans use a fixed term, while income-driven plans tie payments to income and may extend the term. This calculator models a standard fixed-term plan.

Does this include loan forgiveness?

No. Forgiveness programs like PSLF can erase remaining balances after qualifying payments, which this tool does not model.

Should I pay more than the minimum?

Extra payments reduce principal and total interest. Compare the loan rate to potential investment returns to decide.
