How Student Loan Payments Work

Student loans use simple daily interest during in-school and deferment periods, and amortizing monthly payments during repayment. During deferment, interest typically accrues and is capitalized (added to the principal), increasing your total debt. The grace period is the time after graduation before repayment begins. This calculator helps you understand the total cost including accrued interest during deferment and grace periods.
