Student Loan Interest Calculator

A student loan charges interest from the day the money is paid out, not from the day repayment starts, and that interest is added to the principal in one lump when the grace period ends. Enter the amount borrowed, the rate, the months left in school and the grace period, and this returns the interest accrued, the amount that capitalises, the balance repayment begins on and the daily interest charge. A second calculation splits a single payment into interest and principal for the days in the billing cycle. It covers the interest only, not eligibility or the events a loan programme treats as triggering capitalisation.
