Any loans requested while at Relay must be repaid to the federal government with interest. The interest rate for loans disbursed during the 2017-18 academic year was 6%. Interest begins accruing from the date of disbursement.
Your Relay loans will enter repayment when you are no longer enrolled at least half-time at Relay. At that point, you will be responsible for making payments on the full balance of your loans plus any interest that has accrued. The total amount you will end up repaying to the federal government will depend on the total amount borrowed and the repayment plan and timeline you select.
