How We Calculate Student Loan Payments
We first accrue interest during your selected grace period. If you choose to capitalize it, we add that accrued interest to your principal before repayment begins. Monthly payments use the standard amortization formula. Any extra monthly payment is applied directly to principal, reducing total interest and shortening payoff time.
