FAQs – Student Loan Payment Calculator

Interest is the amount of money paid regularly at a particular rate for the use of money borrowed from a student loan lender, or for delaying the repayment of a student loan debt. In essence, it’s the “extra” money you have to pay back the lender for the opportunity to use their money to go to college (or pay off your existing student loans by refinancing).

Interest is calculated as simple daily interest for student loans. This generally means that each day, the outstanding principal balance is multiplied by the interest rate and divided by 365 days to calculate that day’s interest amount. For example, if you have a $10,000 loan and the interest rate is 7%, one day’s interest will be: ($10,000 x 0.07) / 365 = $1.92.

Your repayment term is the amount of time (typically in years) that you are scheduled to repay your loan in full.

When refinancing your student loans, you can also choose a quicker repayment term than the Standard Repayment Plan of 10 years. By choosing a shorter term, you can pay off your loans sooner and get rid of them for good — while maximizing your savings on costly interest.

Yes, it can – and in more than one way. If you get a lower interest rate and/or shorten your repayment term, you save on interest over the life of the loan. On the other hand, if you choose a longer repayment term, you get a lower monthly payment, which can free up room for other monthly expenses.
