Student Loan Calculator
A student loan behaves like any other amortising loan, so the balance, the rate and the payment decide everything else. The payment option turns a balance, a rate and a term into a monthly payment with the total interest it carries. The payoff option goes the other way and turns a payment you can afford into a number of months, with the smaller final payment shown separately. Both assume a fixed rate with no missed or extra payments, and are an estimate rather than financial advice.
