Take the "180-day Premium product" as an example (the description of the trading rules of each product is more effective than this FAQ). Below shows the profit calculation of BIB Rich Rush Investment:
(1) "T" represents subscription date, in which subscription orders will be processed at T+1 day 12:00 (UTC+8). Interest accrual will start right after an order is confirmed;
(2) At expiration, the system will distribute user's subscription amount after fee deduction along with the interest of final day, in which redemption amount at expiration=subscription amount+subscription amount*APR/365-subscription amount*subscription fee-subscription amount*redemption fee;
(3) Interest accrual will start the following day after subscription confirmation, in which daily interest=subscription amount*APR/365.
For instance, user A has subscribed a 7-day product with 10% APR for 1000USDT without any fee charges on January 1.
At January 2, 12:00, the system will confirm his subscription (he can choose to cancel the subscription before 10:00).
At January 3, 12:00, the system will distribute his interest of day 1 which is 1000*0.1/365=0.2739USDT.
At January 4, 12:00, the system will distribute his interest of day 2 which is 0.2739USDT.
Then, daily interest of 0.2739USDT will be distributed the following days before settlement.
At January 9, 12:00, the system will automatically redeem his subscription and distribute his initial investment amount along with last daily interest 1000+0.2739=1000.2739USDT.
Thus, the settlement amount will be received by user A is amounted to 1001.9173USDT.
