마커스 세이빙 어카운트를 열었어요. 친구 리퍼럴을 받아서. 

이자율이 5.4%였는데

제가 $1000불을 넣었는데 이자가 $1.65 붙었던데

이게 이자가 어떻게 계산되는건지 알려주실수 있나요?

5.4%로면 매달 5.4% 붙는게 아닌가요?

채팅으로 물어봤는데,

Thank you for holding. Interest is compounded daily and credited monthly to your account. Interest is calculated using the daily balance method. This method applies a daily periodic rate to the principal and interest that has accrued in the Account each day. This means that the interest from your Account is calculated every day on a 365-day year/ 366-day for leap years. You can view your interest earned by selecting your account and viewing your account activity.

이렇게 설명하는데 이해가 안가서요ㅠㅠㅠ

부탁드립니다.
